I use my turbo timer to warm up my Mr2 GT. Go turn car on, turbo time 5 min, lock door with key. Go back inside have a tofu sundae. Get back in car and she's ready to go. MAD
Garfield Baltista btw running an engine idle in freezing temps? hmmmmssss. it's like appel sirop going through your engine to long. thick sticky lupe like oil doesn't really work at idle tbh. I use 5w40 fully synthetic put that in a freezer over night see what happens.
Jeroen Kerstens, I'm assuming you live somewhere you don't scrape ice off your window 5 months of the year. I do, as do millions of others. most of us have automatic car starters, you know. Sitting on the couch, decide, 'i better warm the car', hit a button on your keys, the car starts. Most of us warm their car at idle for 20 or more mins. All our vehicles are fine, aside from rotting prematurely from all the rock salt they spread on the road whenever it's potentially icy. You clearly don't know enough to be commenting on this sort of shit, bro.
A turbo timer was designed and recommended for the early turbos with a bush rather than bearings as they are today. It allowed the turbo to wind down while still allowing oil pressure to lubricate the bush/bearings.
Thought this was interesting, the manual for my 2004 Volvo v40 says "Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast enough to prevent turbocharger damage. Before switching off the engine, let it operate at idle for a short time to allow the spinning of the turbocharger compressor's turbine vanes to slow. After hard driving, this idle time should last a couple of minutes, during which the vanes will slow and the compressor will cool down while still receiving oil lubrication. If the turbine vanes are spinning at high speeds when the engine is switched off, there is a great risk of heat damage and/or turbine seizure due to lack of lubrication.
IWHBYD 69 I had turbo issues 40k miles ago (now at 130k) and I decided to upgrade from 12t turbo to 16t and get a tune. Car has 250ish HP now (stock was 170) and absolutely rips while getting 30mpg its pretty fun.
U could use that to cool down your car even if it doesnt have a turbo, like the rotary motors in rx8's and rx7's. They require a little cool down time for good engine life and reliability because they run so hot
HWP doesn't regulate modified cars, they raise revenue by issuing bullshit defects that cost you money to get them cleared, even if your car isn't actually defective. It's totally ridiculous.
@@OF01975 Lmao sounds right. me and my mate were in killarney and walked up to a guy who had just burned out and gotten pulled over and dropped all his change, we were super drunk, picked it all up and handed it to him while the cops were like uhhh wtf do you know him we were like nah good luck mates
He's on the MCM Forum plus the guy who helped us organise it called MAX REVSON is also on the forum and knows Edward. Check out the link in the description and you'll find them. Cheers .
The turbo timer I bought (You had me second guessing purchasing one, haha) has many other features like 0-60 timer, 1/4 timer, auto door lock so even though, I do agree, there are many other features they include that make them worth price tag (140-160ish I think). And yes, the added little, "OH it's a turbo thing. You wouldn't understand!" thing is real too, lol.
Turbo timers are actually a VERY good thing to have. Even though cars in the last 25-30 years have been coming with oil and watercooled, most manufacturers recommend you to let the car idle for 30 seconds to 1 minute before shutting off the engine. A lot of Celica GT4s/All Tracs like mine actually come with a decal on the door panel from Toyota telling you this. Also, my mitsubishi eclipse has the same instruction in the owners manual.
I use a HKS tubotimer on my single turbo Toyota Supra, it's cool but im unsure if its nessesary or not. Its an old car with a BIG turbo...Better to be safe than sorry....and its kinda cool :)
Basically this! If it helps even 1%, it may be worth it if it literally saves your engine, lol. I have a BRZ I am boosting soon and it's not the best engine to boost without building the engine. I got the timer in case it might help protect things even a little bit.
They actually do help, most car manuals will say let run at idle for a while to cool. Bc the oil can cook when left sitting in the turbo. Amd watter can boil. Also helps manifolds amd the rest cool down. I've cracked a manifold by turning it off without a cool down
4 years of school and 10 years of experiance as a mechanic under my belt, I did my research. Every car is different, you do the neccesary precausions needed for the car you are working on.
A turbo timer may not be needed for a car. But my 2006 dodge ram 3500 with a oil cooled turbo where my egts can be well over 1300f....a turbo timer is helpful.
4 years later, but this. Definitely not a scam. Plenty of oil cooled turbos out there that need the oil to keep circulating to cool the turbo down and keep wear to a minimum.
Hand brake function is also handy when filling up with fuel. Turn off the engine before putting on the handbrake. Saves waiting for the timer to time out if there isn't an easy off function on the timer. For this reason I wouldn't use the park position on automatic cars.
but when you have a high performance turbo they are not watercooled and when you been driving fast on the highway and suddenly need to pee and you drive fast to a gas station and then turn of your car you are happy you installed a turbo timer to keep oil flowing through your turbo
Great episode. It's cool that even though you're saying that timers are bunk (backed up by reliable sources), you still install one for a guy who wants one.
hate to say it guys but you are absolutely wrong about turbo timers being useless... in water cooled turbo applications this may be the case but not all turbos are water cooled and are only oil cooled. if you go romping around and oil temps are rising and then go to park your car, it is not good for the bearings in an oil cooled only turbo to just shut the car down, this causes coking of the bearings in the turbo, This "coking" will destroy the ability of the grease or oil to lubricate the bearing
I know I'm late to the game, but the theory of a turbo timer has some validity, as in jet engines (which are just very very big turbos where the "engine" has been simplified to a burner unit) you are supposed to let the engine idle before shutoff, the metal of the turbine blades and the turbine housing/compressor blades and compressor housing are of different alloys, and because of this, their expansion rates differ, wherin the compressor/turbine blades expand/contract much more slowly than their housing. So, just for added security that the blades won't contact the housing on cooldown, you idle the engine to allow them to contract and give the housing clearance. Not sure if this principle transfers to an automotive turbo, but it at least gives it some basis in truth.
Hell yeah!! The old turbo Dodge scene is huge here. Mine had the (crap 525) 5spd. 12psi computer. Big downpipe and exhaust. I smoked some 240s and integras in that. lol. Had it a year, put a lot into it, and sold it a few months ago. I looked for an Omni first, lol
For those who only live 5 mins away from work and drive it like we stole it, I'd roll with a turbo timer. 10$ and 20 minutes.. Plus you will have a reliable voltage readout. The hotside will glow red hot after a pull or two, shutting it off right away is not appealing to me as I want everything to cool to operating temperatures, letting that sit an extra 30/60 seconds could make the difference between failure or not on turbo's with high miles still being abused! It get's old trying to go slow or wait a few. :2cents: Pro's System cools to operating temperatures. You have an accurate digital readout of your voltage. You can set your time, and hide the whole unit, even the face plate. Only costs 10$, super easy to install. If the leading country of Forced induction puts one on every car, who has built us some of the best boosted/desired motors known to date... Why think they haven't invested research into this, as their warranty's blow any American automotive warranty out of the water!! Out of box pro Save on starter wear!!! If you deliver pizza's and don't want to leave your keys behind and it's freaking cold... Or any reason you get in and out frequently without being away for over the maximum set time. Cons Some people think they are silly? Made in China/Japan "Quality one's are Japanese" To me, 10$ is worth peace of mind.
Although a turbo timer is absolutely pointless, I do like the idea, especially if you can lock the car and walk off and just let it stop a few seconds later. Then you get to hear your own engine from outside more often. It strikes me as the sort of thing that'll be in modern cars, that the key just has to be in the car to use a push button start and to stop the engine you just park and when the key gets a few metres away then it stops.
Aidan Šeštokas they are not completely useless i am a professional they are basically for impatient people who want to flog there vehicles and shut them down immediately if you let your vehicle back to idle just for a 10 seconds it would be enough so in that case i would say they are useless and in 99% of the vehicles i have fit them to they are just a complete wank but i guess there is worse things to spend your money on
Aidan Šeštokas "Although a turbo timer is absolutely pointless[...]" It's funny to see how you generalize that everyone on earth has a watercooled turbo installed. Those people who don't have a watercooled turbo will suffer from carbon build-up inside the turbo and on the turbo shaft which will lead to an early death of the turbo.
Metatr0n watercooled or not isn't the main issue. It's about the rotation of the turbo assembly. If your car idles for a bit, the whole thing slows down, a lot. If you pull in on full revs, and shut down, your turbo is spinning like mad, and the oil-pressure goes away. Since there isn't any "bearings" in modern turbos, the oil is what keeps the assembly centered, and with no pressure, the assembly just drops down on the metal. In the long run you simply mill bits of the housing, and axle away, making your turbo in to a expensive letter weight.
It's not for cooling your turbo. It's for continuing oil pressure after driving. To prevent oil starvation thus ruining your journal bearings. ANY car you buy that is turbocharged from the factory says to let the car idle for a period of time after hard driving. The timer simplifies this. Though the introduction of ball bearing turbos has changed this a bit. It still helps. I would recommend a turbo timer to anyone with $2500-3000 invested in a turbo. Simple as that.
sucks when driving a wasasaabie (saab) only works if shift up reverse lock is removed... so for saabs a turbo timer doesn't work without ripping gear lever apart. I'm my own turbo yoda
For YEARS I just figured if I ever had a turbo car I’d need a turbo timer. I’d always wanted a turbo but after 12 years of driving cars I finally got one. Every time I drive it, before I stop the car, I’ve been sitting in my car for a minute or two letting the oil cool. Then just a day ago I was told that most modern turbos are wet cooled and have oil cooling while running + liquid cooled while off so you don’t need to let them cool down unless it’s a track day or something. I won’t be installing a turbo timer but I will probably still wait 30 seconds or so just in case
Isn't it best to leave a diesel idling for a few seconds before shutting it off? Surely a 10 second "turbo timer" would be a great addition to an older diesel motor :D
I was told to let my diesel idle for about a minute before shutting it off as the oil going through the bearing in the turbo stops circulating when you shut the engine off and if it's super hot the oil can start evaporating and leaving behind waxy chunky gunky bad stuff residue and that doesn't make a very good lubricant and then your turbo bearings are gone and you start breaking shit so yeah I just take it easy for the last minute of driving like they said and it should be fine. You'd have to be really pushing a diesel for it to get that hot anyways
supercowmoo3 As far as i know, most turbo powered cars actually benefit from a (short) idle before you shut them down. It's not about cooling, or cooking anything. It's about letting the turbo spin down. Modern, cheap turbos, which is what we got in 99% of all vehicles, don't actually have bearings to support the rotating parts, but instead use the oil, and oil-pressure to support the rotating center axle. When you shut down the engine, the pressure drops, and with it, the entire assembly. Fast rotating metal in direct contact with other, stationary metal, causes wear, and sooner or later the bits wear out, and so on. There still are the rare ball bearing turbo's that doesn't really suffer from this, but in general, it's a good idea to let the turbo wind down with oil-pressure. But it has nothing to do with the temperature...
InvisibleYetVisible Funny, since we keep replacing turbos for this specific purpose. High performance turbos are still provided ball bearings, rather then oil film bearings, for the same reason turbos used to have ball bearings in the first place. Your welcome to prove me wrong, of course, but i'd hope your willing to take a few of the broken turbos we replace, and tell them they aren't really broken... Of course. If you actually had an intelligent rebut, it would have been above, so forgive me for ignoring you from hear on and out. Have a nice day.
I have a Blitz turbo timer system and the inlet air temp it allows me to see has always been handy for me to keep the temp of things. Once I learnt to set it up correctly, it will adjust the time the car keeps running depending on the temp it's detecting. Handy stuff indeed and in my Subaru manual, it says to keep the car running for 20-60 seconds after I have finished driving.
I think you replied to the wrong person, I was the one making fun of the guy who said that you should never mod a BMW. But sweet video, that E36 was MAAAAADDDD!!!
Doing that is like putting some $500 dollar sauce on a $2 tofu burger. You're going to try to improve something that isn't great anyway. You're trying to add performance to a non-performance car. I mean obviously if you want to, that's your choice and if you like it then whatever, but you'll probably get a lot of crap for it.
What does being automatic have to do with his mods? Guess you don't realize automatics are faster than stick shifts (Stock vs stock\Mod vs mod), due to human speed and possible cause of error.
Suikakuji Thats not always true... maybe in a ferrari or a lambo with one of those crazy triple clutch transmissions that already has the next gear ready, run by a crazy computer... but in the average car manual is faster road speed wise (not shifting wise). Unless you suck at manual...
there are many exceptions to that rule, as long as the car is in a state where it cant be driven off it is acceptable to have the engine running, that is why turbo timers have to be fitted with a "run lock" that cuts the ignition immediately if the throttle is pressed or the wheels move. as far as I know those are the only conditions required, in the UK anyway (my work van has one for some reason so they brought it up in a training meeting)
turbo timers allow the turbo to slow down after a drive, because they can spin at hundreds of thousands of rpms. it allows the oil to keep circulating through the turbo so as not to cause wear
A turbo timer is a device designed to keep an automotive engine running for a pre-specified period in order to automatically execute the cool-down period required to prevent premature turbo wear and failure. After a period of driving when a turbocharger has been working hard, it is important to let the engine run at idle speed for a period, allowing the compressor assembly to cool from the lower gas temperatures in both the exhaust and intake tracts.
Turbo Timers... it's like being back in the 80's. Turbo timers worked on cars like the Renault 5 GT mk1 where the turbo's were 100% oil cooled which means that immediately switching the car off after a drive would cause the oil pump to also switch off. The oil would stop pumping and natural heat soak would cause the oil in the turbo to burn, gel and turn into sludge. Hence, turbo failure within a few weeks. The last Renault 5 GT mk1 came off the production line in 1986!!! 198-fucking-6 guys. The MK2 released in 1987 had a watercooled turbo and has no need for this marketing gush. I doubt a turbo timer has been necessary on a car for over 20 years. Water cooled turbos obviously solved this but as well, the pump keeps running after the car switches off. Duh.
+daniel krause 90 000 dollars, for a Lancer in a country that has one of highest car tax rates in world, Evo costs around 250-400 000 dollars, MCM has already made video about Singapore and how expensive the cars are there. Though, remember that 90 000 Singapore dollars are just about 62 000 USD or 88 700 Australian dollars. 62 000 USD doesn't sound that bad for a turbo Evo with A/T, i guess in U.S. the price would be around 30-40 000 for new one. Meanwhile here, an Lancer costs 60 000 euros if it's any special at all, Evo costs extra 20-30k Oh, and doesn't Evo 400 cost just 3 grands less than a Nissan GT-R?
I've seen a glowing red exhaust side on a Delica turbo diesel after a highway run. As well on older turbos with ceramic exhaust wheels, not allowing the vehicle to run for a minute or two before shut down can cause the wheel to cool down too quickly and become brittle and or crack. But like they said, a minute or two of light driving before shutting down achieves the same goals.
Let me make it clear that soldering connections will *always* be more reliable than crimping. Unless you plan for your wiring to get 500ºF, soldering is stronger mechanically than crimping, and is capable of carrying more current and without creating a point of high resistance. It also is not susceptible to corrosion like a crimped connector. The ONLY reason someone would prefer not to solder is if they don't know how to do it properly. Learn to solder and you'll never go back to wobbly, high-resistance and corrosion-prone crimp connections.
dregenius it’s not though; heat embrittlement, solder creep. That’s why aircraft wiring is almost all crimped. It’s crimped with calibrated tooling and not a pair of rusty pliers, but it will last 30 years and millions of miles.
Most water pumps are mechanical so after the engine stops so does the flow of coolant, the coolant still does a very good job of removing heat. Turbo timers are insurance, they are there when you need them if you cherry your turbine housing you will be glad you cooled it down with a turbo timer.
Fan for years but guys not soldering! Recent experience:engine fan switch controls thermo fan op, eg Tridon fan switch, Two fail me in 14 months, $48 each, this time I took to the kettle to test, still not work, so i cleaned and soldered the lugs, surprise surprise both switches began working. What you need to be carefull with soldering is earthing your body with an earth strap if working on or near CPU, solder with low temp, use a good brand of solder.
A turbo timer is completely pointless on a water cooled turbo. And any factory turbocharged vehicle doesn't have these timers for a reason because it's pointless. Just to waste your money. At most ill run my car for 30 seconds but unless your turbo is air cooled it doesnt matter.
+mahunik This. Turbo timers are a complete waste of money, water cooled turbo or not. The actual solution is simple.. don't run teh piss out of your car then immediately shut it down.
GB_GREEN Or you could, you know, not run the piss out of the engine right before you shut it down? These worthless timers would cost an OEM like a dollar fifty to integrate into their cars..... but not a single OEM car comes with one. Hmm.... I wonder why?! Watercooling a turbo isn't *just* to cool the turbo either, dipshit. You're an idiot if you think these are necessary.
+elesjuan so you're saying that the coolant a is use to cool the oil? And you're right your vehicle was not design for racing so why you doing it. And if you are going to run your car hard the turbo timer could be useful.
GB_GREEN Whatever dude. You're right. I know absolutely nothing about cars, engines, turbos, or thermodynamics. That's why I build engines, transmissions, turbo systems from scratch, and build / install / tune ECUs. I know nothing and you're the god of automotive knowledge.
At the same time the lubricating oil from the engine is able to circulate properly so the turbine won't burn the lubricating oil that would otherwise be trapped within the charger with the turbine rotating at high speed. With regard to modern automotive turbochargers, the need for a turbo timer can be eliminated by simply ensuring the car does not produce any 'boost' (during driving) for several minutes prior to the ignition being shut off. Most turbo timers are based on digital electronics.
Evo vs. STi...I've always loved the Evo, but my girlfriend's dad just bought a new STi, and it is insane. Not to mention, it is more "user friendly" per say, with heated seats, leather/alcantera, full radio and sound system, and other comfort items. This is a tough battle.
This is a perfect application for the wankle rotary engine, due to its flooding issue at low temps. You need to heat up the car before shutting it off or it will flood. This will leave it on when you walk away solving the issue. As far as other applications its a scam.
The turbo timer in my FTO didn't have a safety cut out on the hand brake. I managed to drive half way home from work with my keys in my pocket.... when the engine cut out on the motorway all of sudden and the power steering died it was great fun.
I just bought a limited edition STI and I love it. Thought about the evo 10 but it has much less luxurys then the subi. Evo 10 is a teak car. You can't even change the steering wheel hight or the seat to make it comfortable.
I have to say I agree with Moog. My S15 had a turbo timer in it when I bought it but I only use it on the track or if I need to leave it running to defrost the windscreen etc. saying that though my work makes turbo timers and we sell tonnes of them to auto electricians.
Hey Guys, speaking for the old 2.3 liter 5 cylinder, it think from roundabout 1984 onwoards (i think both turbo and even non turbo / engines 200 - 20V / 2.3l) AUDI built in a secondary small electrical water pump, which is connected to a simple mechanical tempswitch in engine compartment. The temp switch enables both the water pump and main radiator fan on slow mode, to cool complete engine compartment (engine = off). So if you park the car with (too) hot engine, it would start after-cooler mode after some seconds where hot air built up in engine bay, then stop again when cooled down a bit...and if theres still enought heat from exhaust etc will start again. Still talking for the turbo faction: If kicking your turbo, you should warm up everything before kicking and at least drive around the block once more if it's really hot (which it shouldn't be anymore if you live in a 50km/h or 30km/h zone when reaching your garage...). Just leaving the car idling without moving it, almost always leads to more heat in engine+cooling system. If you got corrections/positive additions, please feel free to add. edit: afaik the turbo is only oil cooled there, but currently available "better" oil will not be f-ed up/crystallize by heat, which could reduce lifetime of turbo bearings. (...if really parking a hot-glowing turbo)
I used to set mine to 15mins and use my turbo timer to warm up the skyline in winter, living in the UK i'd rather be inside with a cup of tea nice and warm while the car gets warm and toasty and helps avoid cold engine damage.
5:10 Multimeter should be set to Ohms, and test for a good connection between the wires on at the 'ON' position. Test the points still connect to the key barrel (obviously). Martin doesn't really explain what he's testing for (perhaps intentionally), but he has the meter set to DC Voltage, which you won't get any since the Ground of the battery has already been disconnected.
Precision Turbo actually recommends running your car for a few minutes before shutdown after hard driving(think between runs at the track). They recommend it so much that they even made a video to emphasize it. I can see how it doesn't matter for daily driving with a water cooled turbo....but most large performance turboes arent watercooled so... $15 for a little insurance against coking in your new $400-$3000 turbo? yea I'm game.
I do agree that most cars do not need them but I had a variation of a turbo timer on my very modified Dodge Ram with a Cummins turbo diesel since it was not a water cooled turbo. My SPA EGT gauge was wired up with some relays to let the truck run until the EGT was below a certain point.
I think it's worth it. (Or at least kinda cool. Water cooling really makes it unnecessary except in cases like my bike) My bike over-runs two minutes after shutdown. Great Channel guys! (The cooling system. Not the engine!)
No.When you immediately turn your turbo car off after a long trip or after you drove it at full boost you risk to blow up your turbo because when you turn the car off the water in the turbo coolling system will get hot because your radiator is off,so when you keep the car running the radiator will spin and cool your water:)
No they are not needed but handy to have if you just wanna lock ur car and pop into dairy for a minute to quickly pick up 1-2 items. most wear and tear happens when you start your car so by reducing the number of times you have to start your car per day, you're not having to shut off and start just for quick stop.
Diesel engines can use something like this, but they use a tempeture probe so shut off the engine when the exhuast temp drops below a certain point. That really comes into play when you are hauling heavy loads.
Since turbo's are oil cooled, it helps keep oil circulating through the turbo after a hard run to keep it lubricated and cooled. You're half right, they're half right.
Boxer engines are what Subarus use. It's a normal int. combustion engine mounted sideways. A Wankel rotary engine was used mostly in Mazda's RX line... They're a completely different still of engine and use rotors instead of cams.
As someone who works with electronics and electrical components regularly. Crimping is the way to go. Hands down. The only solder that was reliable was lead based. Hard to get now. CRIMP THOSE WIRES!
i know you guys are more pointed towards JDM's but i thought it would would be cool if you guys tried and make an off road worthy car or truck. i havent seen a video like that from you and i would love it as i have a 2001 kia sportage truck. love you guys keep it up
I think the turbo timer is rely a precaution because u won't always remember to let it cool down before switching it off. especially when ur the type of person that trashes it every time u pull out the garage
Basically it's not necessary, but with a turbo you're supposed to give you car a cool down period after a hard workout? What if you were just driving nicely and not very aggressively? Still needs to idle /cooldown?
+Ben L yeah, basically when running a turbocharged engine hard u need to give it a period to cool down before switching off the engine. And in my opinion a minute isn't enough when pushing extremely hard especially if the car doesn't have an oil cooler. The theory behind it is that the oil which remains near the turbo burns due to the excess heat and lack of flow. This burns the light part of the oil making it more viscus and hence having to change your oil more regularly. There's a video on engineering explained that talks about this. And well a more viscus oil reduces lubrication and increases engine wear. Day to day, light driving and calm low revs should be fine without a cool down period though. But for longevity of your oil, especially if you use expensive synthetics you should give it a minute to cool at idle before switching off
+Darian Wallace your absolutely right my friend this mighty car guys are idiots. When u stop the engine, you stop the flow of oil and I you just ran your car pretty good the the turbo internals shaft, bearing, bushings get extremely hot and the oil that is running through it to lubricate stops flowing will cause the oil on the parts to boil and yeah...... You get the point. Turbo timers are not meant to cool the turbo but to cool the oil. Correct me if I'm wrong.
It allows the oil in the turbo to remain circulating while it cools, this prevents it from caking on internals and leading to premature failure. Or so the argument goes.
Oh I see, I just glanced over it lol I retract everything I said from being completely off topic haha I've actually set mine up very well for hills and with the right rims and tires it might be able to get close to it ! You are right though, they are very tail happy. Despite that, what I have found with Hillruns is that turbo cars lack A LOT. Even with their power, they don't spool up quick enough to have any benefits over N/A. That's how I have beaten all the cars ! :3
They put turbo timers in, especially oil fed because once the engine is turned off when not let run to cool down, the turbo looses its oil feed and screws the bearings in the turbo so they aren't totally useless.
Every turbo I've seen on a vehicle has been water cooled, its pretty much essential these days. The reason a turbo timer is a waste of money and a marketing scam is because while the coolant in the turbo is hot, the coolant will still circulate through the turbo due to thermal siphoning. That's why the water return placement is always higher on the turbo than the water inlet.
About that turbo timer, i don't think it's rubbish. That's a good thing. When you turn off your ignition when turbo is doing some 100k rpm mad spins. Then the oil pressure is gone and turbo keeps spinnin' with no oil. So, if you want to keep your turbo's bearings good and healthy, you should keep your car running until turbo stops or install a turbo timer. Thanks :)
I think thats what the turbo timer was originally designed for.. If a car with an oil cooled turbo is run hard and then switched off without letting the turbo cool down sufficiently then the heat will soak into the oil that is in the tiny oil galleries in the turbos bronze bearings, which will cook and turn to carbon and eventually block them... Iv seen a few turbos go that way :-)
I think they would be useful for older diesels that don't have water cooled turbos or don't have good water cooling on their turbo. Beyond that, they seem pointless.
The real point in the soldering vs. crimping thing is this: A solder joint leaves a solid point inside the wire where the solder has wicked in and it creates a point where it goes from flexible to non-flexible. It can break there with mechanical bending such as vibration. A good crimp does not do this. Source: I solder for a living and have done J-std certification.
80's Subarus (Leone/Loyale) have water cooled turbos yet there is a factory installed warning sticker on the drivers side door stating that you must let the idle for 2 mins after driving on the highway.
PEOPLE, TURBO TIMER and REMOTE STARTER are 2 different thing.. turbo timer is design to prevent choke oil/line and to prevent damage to bearing, impeller etc. thats why most diesel and forced induction car use turbo timer to equalize the temperature difference between the turbo and outside temperature and also to equalize the thermal expansion due to different metal :)
After pushing a car pretty hard, the turbo is extremely hot and it needs time to cool down before you shut off the car. A turbo timer isnt really necessary, just leave the car on for a minute or two after a little bit of "aggressive" driving
Yup...thats where I connected mine.....to the Handbrake.....so if i need to kill it quick for any reason, I don't have to wait for the time to count down ( as mine doesnt have the power switch ) As far as im concerned - they good - my opinion: • My turbo glows red hot, killing the ignition stops the oil running through the turbo. ( Boosting at 1.2 BAR ) • The turbo has a small shaft that runs through it - If the oil stops, there is a risk of the shaft warping. - rather be safe than sorry.
I use my turbo timer to warm up my Mr2 GT. Go turn car on, turbo time 5 min, lock door with key. Go back inside have a tofu sundae. Get back in car and she's ready to go. MAD
great idea dude will remember!
Garfield Baltista 5 mins is way too long unless it's winter
Garfield Baltista isn't it the same as running your car at idle?
Garfield Baltista btw running an engine idle in freezing temps? hmmmmssss. it's like appel sirop going through your engine to long. thick sticky lupe like oil doesn't really work at idle tbh. I use 5w40 fully synthetic put that in a freezer over night see what happens.
Jeroen Kerstens, I'm assuming you live somewhere you don't scrape ice off your window 5 months of the year. I do, as do millions of others. most of us have automatic car starters, you know. Sitting on the couch, decide, 'i better warm the car', hit a button on your keys, the car starts. Most of us warm their car at idle for 20 or more mins. All our vehicles are fine, aside from rotting prematurely from all the rock salt they spread on the road whenever it's potentially icy.
You clearly don't know enough to be commenting on this sort of shit, bro.
A turbo timer was designed and recommended for the early turbos with a bush rather than bearings as they are today. It allowed the turbo to wind down while still allowing oil pressure to lubricate the bush/bearings.
Should be really handy in my delivery van, I'll be able to lock the van when I go drop off a package and won't have to start it 150+ times a day
Thought this was interesting, the manual for my 2004 Volvo v40 says "Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast enough to prevent turbocharger damage.
Before switching off the engine, let it operate at idle for a short time to allow the spinning of the turbocharger compressor's turbine vanes to slow. After hard driving, this idle time should last a couple of minutes, during which the vanes will slow and the compressor will cool down while still receiving oil lubrication. If the turbine vanes are spinning at high speeds when the engine is switched off, there is a great risk of heat damage and/or turbine seizure due to lack of lubrication.
Swap it out for a SAAB turbo if it ever goes bad ;)
+Hannah Brock saab vs volvo...volvo will take it tbh...if he blows a turbocharger, id go to just upgrading to a v6 and turbo charging that.
IWHBYD 69 I had turbo issues 40k miles ago (now at 130k) and I decided to upgrade from 12t turbo to 16t and get a tune. Car has 250ish HP now (stock was 170) and absolutely rips while getting 30mpg its pretty fun.
you swapped the 2.0 low pressure turbo for the T4 turbo without doing anything just remapping? How well is it?
+rudkacka Well due to unrelated issues it no longer runs so sadly not very well :(
Like me, I wonder how many other people watch these videos even though they don't own a car with a Turbo?
me, i have a 97 nissan hardbody 2.4l N/A mini truck
Same here, I've a 2.5L V6 Lexus but wish to know what it would be with a turbo!
yeah i would like to put a turbo kit on my nissan, but i would need to rebuild my engine first. i have 215,400+ miles
Lol. I have a 69 Mini Cooper no turbo what so ever
I don't even have a car!
U could use that to cool down your car even if it doesnt have a turbo, like the rotary motors in rx8's and rx7's. They require a little cool down time for good engine life and reliability because they run so hot
Its an engine not a motor

HWP doesn't regulate modified cars, they raise revenue by issuing bullshit defects that cost you money to get them cleared, even if your car isn't actually defective. It's totally ridiculous.

He's on the MCM Forum plus the guy who helped us organise it called MAX REVSON is also on the forum and knows Edward. Check out the link in the description and you'll find them. Cheers .
The turbo timer I bought (You had me second guessing purchasing one, haha) has many other features like 0-60 timer, 1/4 timer, auto door lock so even though, I do agree, there are many other features they include that make them worth price tag (140-160ish I think). And yes, the added little, "OH it's a turbo thing. You wouldn't understand!" thing is real too, lol.
Turbo timers are actually a VERY good thing to have. Even though cars in the last 25-30 years have been coming with oil and watercooled, most manufacturers recommend you to let the car idle for 30 seconds to 1 minute before shutting off the engine. A lot of Celica GT4s/All Tracs like mine actually come with a decal on the door panel from Toyota telling you this. Also, my mitsubishi eclipse has the same instruction in the owners manual.
I use a HKS tubotimer on my single turbo Toyota Supra, it's cool but im unsure if its nessesary or not. Its an old car with a BIG turbo...Better to be safe than sorry....and its kinda cool :)
Basically this! If it helps even 1%, it may be worth it if it literally saves your engine, lol. I have a BRZ I am boosting soon and it's not the best engine to boost without building the engine. I got the timer in case it might help protect things even a little bit.
They actually do help, most car manuals will say let run at idle for a while to cool. Bc the oil can cook when left sitting in the turbo. Amd watter can boil. Also helps manifolds amd the rest cool down. I've cracked a manifold by turning it off without a cool down
Loved the episode guys! Especially love the last few minutes when you basically summarize the positives and negatives!
I think Im going to install a turbo timer on my N/A Mustang.
I have it on my N/A Minivan ..
4 years of school and 10 years of experiance as a mechanic under my belt, I did my research. Every car is different, you do the neccesary precausions needed for the car you are working on.
A turbo timer may not be needed for a car. But my 2006 dodge ram 3500 with a oil cooled turbo where my egts can be well over 1300f....a turbo timer is helpful.
4 years later, but this. Definitely not a scam. Plenty of oil cooled turbos out there that need the oil to keep circulating to cool the turbo down and keep wear to a minimum.
Hand brake function is also handy when filling up with fuel. Turn off the engine before putting on the handbrake. Saves waiting for the timer to time out if there isn't an easy off function on the timer. For this reason I wouldn't use the park position on automatic cars.
but when you have a high performance turbo they are not watercooled and when you been driving fast on the highway and suddenly need to pee and you drive fast to a gas station and then turn of your car you are happy you installed a turbo timer to keep oil flowing through your turbo
Great episode. It's cool that even though you're saying that timers are bunk (backed up by reliable sources), you still install one for a guy who wants one.
hate to say it guys but you are absolutely wrong about turbo timers being useless... in water cooled turbo applications this may be the case but not all turbos are water cooled and are only oil cooled. if you go romping around and oil temps are rising and then go to park your car, it is not good for the bearings in an oil cooled only turbo to just shut the car down, this causes coking of the bearings in the turbo, This "coking" will destroy the ability of the grease or oil to lubricate the bearing
I know I'm late to the game, but the theory of a turbo timer has some validity, as in jet engines (which are just very very big turbos where the "engine" has been simplified to a burner unit) you are supposed to let the engine idle before shutoff, the metal of the turbine blades and the turbine housing/compressor blades and compressor housing are of different alloys, and because of this, their expansion rates differ, wherin the compressor/turbine blades expand/contract much more slowly than their housing. So, just for added security that the blades won't contact the housing on cooldown, you idle the engine to allow them to contract and give the housing clearance. Not sure if this principle transfers to an automotive turbo, but it at least gives it some basis in truth.

Hell yeah!! The old turbo Dodge scene is huge here. Mine had the (crap 525) 5spd. 12psi computer. Big downpipe and exhaust. I smoked some 240s and integras in that. lol. Had it a year, put a lot into it, and sold it a few months ago. I looked for an Omni first, lol
For those who only live 5 mins away from work and drive it like we stole it, I'd roll with a turbo timer. 10$ and 20 minutes.. Plus you will have a reliable voltage readout. The hotside will glow red hot after a pull or two, shutting it off right away is not appealing to me as I want everything to cool to operating temperatures, letting that sit an extra 30/60 seconds could make the difference between failure or not on turbo's with high miles still being abused! It get's old trying to go slow or wait a few. :2cents:
Pro's
System cools to operating temperatures.
You have an accurate digital readout of your voltage.
You can set your time, and hide the whole unit, even the face plate.
Only costs 10$, super easy to install.

Although a turbo timer is absolutely pointless, I do like the idea, especially if you can lock the car and walk off and just let it stop a few seconds later. Then you get to hear your own engine from outside more often. It strikes me as the sort of thing that'll be in modern cars, that the key just has to be in the car to use a push button start and to stop the engine you just park and when the key gets a few metres away then it stops.
It's not useless.. It saves the turbo.
Stuart Campbell You didn't see the bit about 20 different professionals saying that they are rubbish, did you?
Aidan Šeštokas they are not completely useless i am a professional they are basically for impatient people who want to flog there vehicles and shut them down immediately if you let your vehicle back to idle just for a 10 seconds it would be enough so in that case i would say they are useless and in 99% of the vehicles i have fit them to they are just a complete wank but i guess there is worse things to spend your money on
Aidan Šeštokas "Although a turbo timer is absolutely pointless[...]" It's funny to see how you generalize that everyone on earth has a watercooled turbo installed. Those people who don't have a watercooled turbo will suffer from carbon build-up inside the turbo and on the turbo shaft which will lead to an early death of the turbo.
Metatr0n watercooled or not isn't the main issue. It's about the rotation of the turbo assembly. If your car idles for a bit, the whole thing slows down, a lot. If you pull in on full revs, and shut down, your turbo is spinning like mad, and the oil-pressure goes away. Since there isn't any "bearings" in modern turbos, the oil is what keeps the assembly centered, and with no pressure, the assembly just drops down on the metal. In the long run you simply mill bits of the housing, and axle away, making your turbo in to a expensive letter weight.
It's not for cooling your turbo. It's for continuing oil pressure after driving. To prevent oil starvation thus ruining your journal bearings. ANY car you buy that is turbocharged from the factory says to let the car idle for a period of time after hard driving. The timer simplifies this.
Though the introduction of ball bearing turbos has changed this a bit. It still helps.
I would recommend a turbo timer to anyone with $2500-3000 invested in a turbo. Simple as that.
sucks when driving a wasasaabie (saab) only works if shift up reverse lock is removed... so for saabs a turbo timer doesn't work without ripping gear lever apart. I'm my own turbo yoda
For YEARS I just figured if I ever had a turbo car I’d need a turbo timer. I’d always wanted a turbo but after 12 years of driving cars I finally got one. Every time I drive it, before I stop the car, I’ve been sitting in my car for a minute or two letting the oil cool. Then just a day ago I was told that most modern turbos are wet cooled and have oil cooling while running + liquid cooled while off so you don’t need to let them cool down unless it’s a track day or something. I won’t be installing a turbo timer but I will probably still wait 30 seconds or so just in case
Isn't it best to leave a diesel idling for a few seconds before shutting it off?
Surely a 10 second "turbo timer" would be a great addition to an older diesel motor :D
I was told to let my diesel idle for about a minute before shutting it off as the oil going through the bearing in the turbo stops circulating when you shut the engine off and if it's super hot the oil can start evaporating and leaving behind waxy chunky gunky bad stuff residue and that doesn't make a very good lubricant and then your turbo bearings are gone and you start breaking shit so yeah I just take it easy for the last minute of driving like they said and it should be fine. You'd have to be really pushing a diesel for it to get that hot anyways
supercowmoo3 What you are referring to is the oil 'cooking'.
supercowmoo3 As far as i know, most turbo powered cars actually benefit from a (short) idle before you shut them down. It's not about cooling, or cooking anything. It's about letting the turbo spin down. Modern, cheap turbos, which is what we got in 99% of all vehicles, don't actually have bearings to support the rotating parts, but instead use the oil, and oil-pressure to support the rotating center axle. When you shut down the engine, the pressure drops, and with it, the entire assembly. Fast rotating metal in direct contact with other, stationary metal, causes wear, and sooner or later the bits wear out, and so on. There still are the rare ball bearing turbo's that doesn't really suffer from this, but in general, it's a good idea to let the turbo wind down with oil-pressure.
But it has nothing to do with the temperature...
Mr B This is one of the least educated replies I've ever read in my life. Terrific.
InvisibleYetVisible
Funny, since we keep replacing turbos for this specific purpose. High performance turbos are still provided ball bearings, rather then oil film bearings, for the same reason turbos used to have ball bearings in the first place.
Your welcome to prove me wrong, of course, but i'd hope your willing to take a few of the broken turbos we replace, and tell them they aren't really broken...
Of course. If you actually had an intelligent rebut, it would have been above, so forgive me for ignoring you from hear on and out.
Have a nice day.
First jack up your car... The most important thing to do when modding your vehicle.
I have a Blitz turbo timer system and the inlet air temp it allows me to see has always been handy for me to keep the temp of things. Once I learnt to set it up correctly, it will adjust the time the car keeps running depending on the temp it's detecting. Handy stuff indeed and in my Subaru manual, it says to keep the car running for 20-60 seconds after I have finished driving.
"Does he use shrimps ?" ......"what's a shrimp?" ....."it's a prawn Mate !"
I just pissed myself laughing lol
I think you replied to the wrong person, I was the one making fun of the guy who said that you should never mod a BMW. But sweet video, that E36 was MAAAAADDDD!!!
It's a performance car, that's modded and everything, and it's an auto...
Do u feel it was a good idea to mod an auto. Serious question bc im thinkin of doin the same
Doing that is like putting some $500 dollar sauce on a $2 tofu burger. You're going to try to improve something that isn't great anyway. You're trying to add performance to a non-performance car. I mean obviously if you want to, that's your choice and if you like it then whatever, but you'll probably get a lot of crap for it.
Tru. I have also thought about switching the transmission but it might b to costly. I have a 2000 jetta 1.8t
What does being automatic have to do with his mods? Guess you don't realize automatics are faster than stick shifts (Stock vs stock\Mod vs mod), due to human speed and possible cause of error.
Suikakuji Thats not always true... maybe in a ferrari or a lambo with one of those crazy triple clutch transmissions that already has the next gear ready, run by a crazy computer... but in the average car manual is faster road speed wise (not shifting wise). Unless you suck at manual...
there are many exceptions to that rule, as long as the car is in a state where it cant be driven off it is acceptable to have the engine running, that is why turbo timers have to be fitted with a "run lock" that cuts the ignition immediately if the throttle is pressed or the wheels move. as far as I know those are the only conditions required, in the UK anyway (my work van has one for some reason so they brought it up in a training meeting)
3:54 Why do I need to jack up the car?
+YOLO Magee IT's a running joke for them
turbo timers allow the turbo to slow down after a drive, because they can spin at hundreds of thousands of rpms. it allows the oil to keep circulating through the turbo so as not to cause wear
MAKE SURE YOU FOLLOW THE INSTRUCTIONS!! I forgot to jack up my car and ruined my flux capacitor.
A turbo timer is a device designed to keep an automotive engine running for a pre-specified period in order to automatically execute the cool-down period required to prevent premature turbo wear and failure. After a period of driving when a turbocharger has been working hard, it is important to let the engine run at idle speed for a period, allowing the compressor assembly to cool from the lower gas temperatures in both the exhaust and intake tracts.
Turbo Timers... it's like being back in the 80's. Turbo timers worked on cars like the Renault 5 GT mk1 where the turbo's were 100% oil cooled which means that immediately switching the car off after a drive would cause the oil pump to also switch off. The oil would stop pumping and natural heat soak would cause the oil in the turbo to burn, gel and turn into sludge. Hence, turbo failure within a few weeks.
The last Renault 5 GT mk1 came off the production line in 1986!!! 198-fucking-6 guys. The MK2 released in 1987 had a watercooled turbo and has no need for this marketing gush.
I doubt a turbo timer has been necessary on a car for over 20 years. Water cooled turbos obviously solved this but as well, the pump keeps running after the car switches off. Duh.
you watch the video m8?
I have a 240Z and an AE86 and I like them both in different ways.
Keep da love brotha :)
90,000$ oh my lord in Michigan you can pick one up for like 2,500-10,000$...I'm good
+daniel krause They said: when new... You can't get a new Evo for $10.000.
+OverSoft that's not an EVO. It's a Lancer with a turbo kit.
Meat Amigo Who cares...
+OverSoft new they'd be 25K watch the documentary from them you'll find out why its 90K
+daniel krause 90 000 dollars, for a Lancer in a country that has one of highest car tax rates in world, Evo costs around 250-400 000 dollars, MCM has already made video about Singapore and how expensive the cars are there.
Though, remember that 90 000 Singapore dollars are just about 62 000 USD or 88 700 Australian dollars.
62 000 USD doesn't sound that bad for a turbo Evo with A/T, i guess in U.S. the price would be around 30-40 000 for new one.
Meanwhile here, an Lancer costs 60 000 euros if it's any special at all, Evo costs extra 20-30k
Oh, and doesn't Evo 400 cost just 3 grands less than a Nissan GT-R?
I've seen a glowing red exhaust side on a Delica turbo diesel after a highway run. As well on older turbos with ceramic exhaust wheels, not allowing the vehicle to run for a minute or two before shut down can cause the wheel to cool down too quickly and become brittle and or crack. But like they said, a minute or two of light driving before shutting down achieves the same goals.
Let me make it clear that soldering connections will *always* be more reliable than crimping. Unless you plan for your wiring to get 500ºF, soldering is stronger mechanically than crimping, and is capable of carrying more current and without creating a point of high resistance. It also is not susceptible to corrosion like a crimped connector. The ONLY reason someone would prefer not to solder is if they don't know how to do it properly. Learn to solder and you'll never go back to wobbly, high-resistance and corrosion-prone crimp connections.
dregenius it’s not though; heat embrittlement, solder creep. That’s why aircraft wiring is almost all crimped. It’s crimped with calibrated tooling and not a pair of rusty pliers, but it will last 30 years and millions of miles.
Most water pumps are mechanical so after the engine stops so does the flow of coolant, the coolant still does a very good job of removing heat. Turbo timers are insurance, they are there when you need them if you cherry your turbine housing you will be glad you cooled it down with a turbo timer.
you installed it then totally SLAMMED the hell out of it, hope he wasnt listening lolol
Fan for years but guys not soldering! Recent experience:engine fan switch controls thermo fan op, eg Tridon fan switch, Two fail me in 14 months, $48 each, this time I took to the kettle to test, still not work, so i cleaned and soldered the lugs, surprise surprise both switches began working. What you need to be carefull with soldering is earthing your body with an earth strap if working on or near CPU, solder with low temp, use a good brand of solder.
A turbo timer is completely pointless on a water cooled turbo. And any factory turbocharged vehicle doesn't have these timers for a reason because it's pointless. Just to waste your money. At most ill run my car for 30 seconds but unless your turbo is air cooled it doesnt matter.
+mahunik This. Turbo timers are a complete waste of money, water cooled turbo or not. The actual solution is simple.. don't run teh piss out of your car then immediately shut it down.
You my friend you're an idiot. Do your research. Turbo timers is not to cool your turbo but let the oil cool down. If u want me to explain let me know
GB_GREEN Or you could, you know, not run the piss out of the engine right before you shut it down?
These worthless timers would cost an OEM like a dollar fifty to integrate into their cars..... but not a single OEM car comes with one. Hmm.... I wonder why?! Watercooling a turbo isn't *just* to cool the turbo either, dipshit.
You're an idiot if you think these are necessary.
+elesjuan so you're saying that the coolant a is use to cool the oil? And you're right your vehicle was not design for racing so why you doing it. And if you are going to run your car hard the turbo timer could be useful.
GB_GREEN Whatever dude. You're right. I know absolutely nothing about cars, engines, turbos, or thermodynamics. That's why I build engines, transmissions, turbo systems from scratch, and build / install / tune ECUs. I know nothing and you're the god of automotive knowledge.
At the same time the lubricating oil from the engine is able to circulate properly so the turbine won't burn the lubricating oil that would otherwise be trapped within the charger with the turbine rotating at high speed. With regard to modern automotive turbochargers, the need for a turbo timer can be eliminated by simply ensuring the car does not produce any 'boost' (during driving) for several minutes prior to the ignition being shut off. Most turbo timers are based on digital electronics.
How can we visit Edward in prison?
sanityd1 if he exceeded 90kph in Singapore highways
Evo vs. STi...I've always loved the Evo, but my girlfriend's dad just bought a new STi, and it is insane. Not to mention, it is more "user friendly" per say, with heated seats, leather/alcantera, full radio and sound system, and other comfort items. This is a tough battle.
This is a perfect application for the wankle rotary engine, due to its flooding issue at low temps. You need to heat up the car before shutting it off or it will flood. This will leave it on when you walk away solving the issue. As far as other applications its a scam.
The turbo timer in my FTO didn't have a safety cut out on the hand brake. I managed to drive half way home from work with my keys in my pocket.... when the engine cut out on the motorway all of sudden and the power steering died it was great fun.
31 second intro is not appreciated.
well fast forward....
I have to say, that is probably my favorite Mitsubishi of all time. That car is 1000% clean (even with the silly Altezza taillights!)
+Matt Bonaccio that is the OEM taillights for ralliart version. thats why its turbocharged
I just bought a limited edition STI and I love it. Thought about the evo 10 but it has much less luxurys then the subi. Evo 10 is a teak car. You can't even change the steering wheel hight or the seat to make it comfortable.
I have to say I agree with Moog. My S15 had a turbo timer in it when I bought it but I only use it on the track or if I need to leave it running to defrost the windscreen etc. saying that though my work makes turbo timers and we sell tonnes of them to auto electricians.
Hey Guys,
speaking for the old 2.3 liter 5 cylinder, it think from roundabout 1984 onwoards
(i think both turbo and even non turbo / engines 200 - 20V / 2.3l)
AUDI built in a secondary small electrical water pump, which is connected to a simple mechanical tempswitch in engine compartment. The temp switch enables both the water pump and main radiator fan on slow mode,
to cool complete engine compartment (engine = off).
So if you park the car with (too) hot engine, it would start after-cooler mode after some seconds where hot air built up in engine bay, then stop again when cooled down a bit...and if theres still enought heat from exhaust etc will start again.
Still talking for the turbo faction:
If kicking your turbo, you should warm up everything before kicking and at least drive around the block once more if it's really hot (which it shouldn't be anymore if you live in a 50km/h or 30km/h zone when reaching your garage...).
Just leaving the car idling without moving it, almost always leads to more heat in engine+cooling system.
If you got corrections/positive additions, please feel free to add.
edit: afaik the turbo is only oil cooled there,
but currently available "better" oil will not be f-ed up/crystallize by heat, which could reduce lifetime of turbo bearings.
(...if really parking a hot-glowing turbo)
If you guys are ever in the States, I have a GTR in Georgia we could have some fun with. love your videos!
I used to set mine to 15mins and use my turbo timer to warm up the skyline in winter, living in the UK i'd rather be inside with a cup of tea nice and warm while the car gets warm and toasty and helps avoid cold engine damage.
Come to New Zealand please and install a turbo timer on my r33 🤙🏾 summer down Mount Maunganui is awesome.. come and look see!
5:10 Multimeter should be set to Ohms, and test for a good connection between the wires on at the 'ON' position. Test the points still connect to the key barrel (obviously).
Martin doesn't really explain what he's testing for (perhaps intentionally), but he has the meter set to DC Voltage, which you won't get any since the Ground of the battery has already been disconnected.
Precision Turbo actually recommends running your car for a few minutes before shutdown after hard driving(think between runs at the track). They recommend it so much that they even made a video to emphasize it. I can see how it doesn't matter for daily driving with a water cooled turbo....but most large performance turboes arent watercooled so... $15 for a little insurance against coking in your new $400-$3000 turbo? yea I'm game.
Best advice from video 6:02 - 6:08! But it made a world of difference in my Geo Metro! Pulled 68 more HP outta my lil 3cylinder!
more videos please. been watching you guys for years. so much better them cars shows on tv and other youtube shows
i like the way people have to listen to the sound of your car for another minute!
I do agree that most cars do not need them but I had a variation of a turbo timer on my very modified Dodge Ram with a Cummins turbo diesel since it was not a water cooled turbo. My SPA EGT gauge was wired up with some relays to let the truck run until the EGT was below a certain point.
I think it's worth it. (Or at least kinda cool. Water cooling really makes it unnecessary except in cases like my bike) My bike over-runs two minutes after shutdown. Great Channel guys! (The cooling system. Not the engine!)
No.When you immediately turn your turbo car off after a long trip or after you drove it at full boost you risk to blow up your turbo because when you turn the car off the water in the turbo coolling system will get hot because your radiator is off,so when you keep the car running the radiator will spin and cool your water:)
No they are not needed but handy to have if you just wanna lock ur car and pop into dairy for a minute to quickly pick up 1-2 items. most wear and tear happens when you start your car so by reducing the number of times you have to start your car per day, you're not having to shut off and start just for quick stop.
Diesel engines can use something like this, but they use a tempeture probe so shut off the engine when the exhuast temp drops below a certain point.
That really comes into play when you are hauling heavy loads.
I watch MCM and I don't even have a car. That's how much I like this show.
Turbos spin in the 100k RPM range. They don't slow down in a matter of seconds. Moreover, they still spin at idle even. So it does make sense.
Since turbo's are oil cooled, it helps keep oil circulating through the turbo after a hard run to keep it lubricated and cooled. You're half right, they're half right.
Boxer engines are what Subarus use. It's a normal int. combustion engine mounted sideways. A Wankel rotary engine was used mostly in Mazda's RX line... They're a completely different still of engine and use rotors instead of cams.
As someone who works with electronics and electrical components regularly. Crimping is the way to go. Hands down. The only solder that was reliable was lead based. Hard to get now. CRIMP THOSE WIRES!
i know you guys are more pointed towards JDM's but i thought it would would be cool if you guys tried and make an off road worthy car or truck. i havent seen a video like that from you and i would love it as i have a 2001 kia sportage truck. love you guys keep it up
I think the turbo timer is rely a precaution because u won't always remember to let it cool down before switching it off. especially when ur the type of person that trashes it every time u pull out the garage
Basically it's not necessary, but with a turbo you're supposed to give you car a cool down period after a hard workout? What if you were just driving nicely and not very aggressively? Still needs to idle /cooldown?
+Ben L yeah, basically when running a turbocharged engine hard u need to give it a period to cool down before switching off the engine. And in my opinion a minute isn't enough when pushing extremely hard especially if the car doesn't have an oil cooler. The theory behind it is that the oil which remains near the turbo burns due to the excess heat and lack of flow. This burns the light part of the oil making it more viscus and hence having to change your oil more regularly. There's a video on engineering explained that talks about this. And well a more viscus oil reduces lubrication and increases engine wear. Day to day, light driving and calm low revs should be fine without a cool down period though. But for longevity of your oil, especially if you use expensive synthetics you should give it a minute to cool at idle before switching off
+Darian Wallace your absolutely right my friend this mighty car guys are idiots. When u stop the engine, you stop the flow of oil and I you just ran your car pretty good the the turbo internals shaft, bearing, bushings get extremely hot and the oil that is running through it to lubricate stops flowing will cause the oil on the parts to boil and yeah...... You get the point. Turbo timers are not meant to cool the turbo but to cool the oil. Correct me if I'm wrong.
It allows the oil in the turbo to remain circulating while it cools, this prevents it from caking on internals and leading to premature failure.
Or so the argument goes.
Oh I see, I just glanced over it lol
I retract everything I said from being completely off topic haha
I've actually set mine up very well for hills and with the right rims and tires it might be able to get close to it !
You are right though, they are very tail happy.
Despite that, what I have found with Hillruns is that turbo cars lack A LOT.
Even with their power, they don't spool up quick enough to have any benefits over N/A.
That's how I have beaten all the cars ! :3
Poor fella Marty , ALWAYS doin all the work .
They put turbo timers in, especially oil fed because once the engine is turned off when not let run to cool down, the turbo looses its oil feed and screws the bearings in the turbo so they aren't totally useless.
I totally agree that soldering is outdated. Using crimps and other connectors is so much easier, safer, and there's easier to undo.
yup, means this is a sick mod. MCM are big fans of MAD stuffs!
Every turbo I've seen on a vehicle has been water cooled, its pretty much essential these days.
The reason a turbo timer is a waste of money and a marketing scam is because while the coolant in the turbo is hot, the coolant will still circulate through the turbo due to thermal siphoning. That's why the water return placement is always higher on the turbo than the water inlet.
About that turbo timer, i don't think it's rubbish. That's a good thing.
When you turn off your ignition when turbo is doing some 100k rpm mad spins.
Then the oil pressure is gone and turbo keeps spinnin' with no oil.
So, if you want to keep your turbo's bearings good and healthy, you should keep your car running until turbo stops or install a turbo timer.
Thanks :)
Turbo timers can usually be disabled by an external switch, this is normally done using the handbrake switch, or using an automatic
I think thats what the turbo timer was originally designed for.. If a car with an oil cooled turbo is run hard and then switched off without letting the turbo cool down sufficiently then the heat will soak into the oil that is in the tiny oil galleries in the turbos bronze bearings, which will cook and turn to carbon and eventually block them... Iv seen a few turbos go that way :-)
Just made my day with all the Mitsu love. Maybe one day you'll actually get your hands on an evo. Then you'll finally have a proper car to work on!
Are those nike classics Marty? If so then you are the man. Fly cars. Fly sneakers. MAAADD!!!
Those bloopers revealed the future
I think they would be useful for older diesels that don't have water cooled turbos or don't have good water cooling on their turbo. Beyond that, they seem pointless.
The real point in the soldering vs. crimping thing is this:
A solder joint leaves a solid point inside the wire where the solder has wicked in and it creates a point where it goes from flexible to non-flexible. It can break there with mechanical bending such as vibration. A good crimp does not do this.
Source: I solder for a living and have done J-std certification.
80's Subarus (Leone/Loyale) have water cooled turbos yet there is a factory installed warning sticker on the drivers side door stating that you must let the idle for 2 mins after driving on the highway.
PEOPLE, TURBO TIMER and REMOTE STARTER are 2 different thing.. turbo timer is design to prevent choke oil/line and to prevent damage to bearing, impeller etc. thats why most diesel and forced induction car use turbo timer to equalize the temperature difference between the turbo and outside temperature and also to equalize the thermal expansion due to different metal :)
I love how the last few words of an episode about turbo timers somehow winds up being
"prawn legs & egg shells" :')
After pushing a car pretty hard, the turbo is extremely hot and it needs time to cool down before you shut off the car. A turbo timer isnt really necessary, just leave the car on for a minute or two after a little bit of "aggressive" driving
hi mcm ur vids r epic i watch it all the time .
p.s i live in New Zealand
Yup...thats where I connected mine.....to the Handbrake.....so if i need to kill it quick for any reason, I don't have to wait for the time to count down ( as mine doesnt have the power switch )
As far as im concerned - they good - my opinion:
• My turbo glows red hot, killing the ignition stops the oil running through the turbo. ( Boosting at 1.2 BAR )
• The turbo has a small shaft that runs through it - If the oil stops, there is a risk of the shaft warping. - rather be safe than sorry.
MCM with another new vid?!?! Awwww yeaaa!!
