These are some of our tips for keeping the car cool.. What are yours?
I'm always in front so I never have an issue with getting max airflow to my radiator :-) LOL!
One other thing, a vacuum filler is a life saver. I have a Lotus Elise where there are numerous runs in the coolant system that trap air. Filling the system without it is a complete pain in the ass!
Electric water pump/assist pump
Mine is having a working fan clutch with a proper shroud
Turbulators prevent laminar flow and keep the liquid in turbulent flow. Turbulators are tuned to the cfm of the flow. Anything below the minimum cfm and the liquid will remain in laminar flow and the radiator will not cool as well.
Mike is the most genuine car enthusiast/tuner out there. Love these videos!
Great video Mike
Mike is the kinda guy you can talk with in any environment for hours and have a pleasant, no-B.S. experience.
This man spittin fax.
Mike always spittin fax.
Straight fax
For a few decades now
Always does
Lol sometimes but not really
Watching him talk, you can tell Mike truly loves cars.
I love the mention of electrolysis/ galvanic corrosion inside the engine. Mike, I swear if I ever have the money I'm going to send my 3SGE for you all to build. Love your content ❤
This guy is so chill but he really knows his stuff.
I remember walking into O’Reilley’s and asking for water wetter. Dude behind the counter didn’t even skip a beat and told me they didn’t carry that. I walked around the store and found it. Same dude ring me up and was like, “huh, I didn’t know we sold that.”
Walking performance-car-guy encyclopedia. What a legend this Mike dude.
Great advice. If I may offer advice not mentioned: A mechanical clutch fan. I had done all of the mentioned tips in this video and my time attack camaro with a stout 383 would always get too hot on track. I had a popular oem electric fan setup on it and rather than spend 500+ on an insane brushless electric I simply bought a stock mechanical fan with thermal clutch. I deliberately left it unshrouded so that vortex ring state would limit hp loss at high rpm. I also went to an underdrive crank pulley. I also was able to duct the "prop wash" out of the hood quite easily.
IMMEDIATELY solved my cooling issues and set new personal lap records.
Just imagine what even a 3 hp electric motor looks like in size and youll realize no electric fan can really pull much air because they simply don't have enough power to do so.
I saved 6 lbs off the front end of the car to boot.
Water wetter is AWESOME. I put it in my truck that I tow with. I was staying at 230F-240F consistently pulling a trailer up the mountains in Colorado. Then I did a cooling system flush and changed the radiator and added water wetter. Never get above 220F now.
Do a video on braking system setups 👍great videos btw
Good Idea!
When I heard Sacrificial Anode it was right their you know Mike Kojima knows something about chemical engineering, Pretty cool I love proven science and engineering.
I freaking love this guy. TONS of knowledge.
Spent forever trying to stop my turbo miata from getting hot on the highway and what fixed it was making an air dam/duct so no air could go around the radiator and intercooler. After like 10 minutes on the highway I would have to pull over and after I swapped it it keeps it cool enough the thermostat doesn’t have to open. I made it out of the same stuff people use for signs in their yard. Like those vote for this senator/ governor ones.
Cardboard is your best friend when doing home built fab projects on a budget!
Adding an under tray greatly improves radiator efficiency.
Because without one high pressure air builds up into engine bay from under.
And this can actually cause the radiator air flow to be so obstructed it actually reversed.
Look it up.
Don’t spend your fuel catching air in the front of the car.
Spend it spinning the tires.
You were probably missing your under tray.
I love watching your videos Mike! Always so easy to digest and so informative! I'm an apprentice mechanic, not much money to pay for expensive stuff ups, so thank you for sharing your hard earned knowledge!
Yes, couldn't of said it better myself
This guy should be in a podcast.
Man that’s so good you mentioned cavitation.
My classic ford mk1 escort has a Kent 1600-1700(90tho over sized) that revs to 8000rmp. The cast aluminium coolant outlet on the head shows massive cavities in the alloy after only 1500km of hard driving.
To the point I had a smaller crank pulley made. The alternator doesn’t like 8k either, so hopefully that is better now to.
If we could harvest cavitations energy for say pre combustion chambers water injection charge, we might be onto something.🇦🇺🤜🏼🤛🏼😎🍀😊😊
Most coolant flanges and block/head outlets benefit from porting.
Easier flow
Means less cavitation.
Great video. We are struggling with an LS in a 350z. We added a swirl pot (Merlin Motorsport - UK), lower thermostat (Summit racing 160), higher pressure cap (Moroso 23-25) and a vented hood. It might be our radiator, so that's next. We bought an expensive Flex-A-Lite (they quit making radiators recently) so we will probably go with a Koyorad next.
A 350z is one of the cars where an air lift is a must because the radiator is so low, we have to keep sucking for about 20 min, run the car and repeat a few times.
I’ve seen bro in quite a few videos about different areas and a bunch of insightful tips… I’d definitely pay him whatever he wants to build a car for me…
The bleeder funnel with the lid works well with the liquid block test kits - All you need to do is cut approx 1" hole in that lid so the block test kit's tapered rubber bottom fits snuggly. Keep the coolant level in the tapered part of the funnel and use the block test kit as normal. I've gotten best results with this
Ooooh that’s a good idea!
Thanks!
It always sucks to lower the coolant level for the test and have the coolant level rise and spoil the test
Awesome video! Thank you for all the great info! 🤙
This is easily becoming my favorite channel
Thanks for your time.
Super informative as always love the channel❤️
These Moto iq videos are such a great informative resource 🙏🏼
omg i like this guy vids he is so calm and kind and honest and he knows what he talking about
Thank you Mike.
Always the best advice from this man!
Thanks man. Lots of useful information and products I had no idea about. Appreciate it.
Great stuff Mike. Thanks.
Thank you Mr. Treasure Trove! Love all your video's sir! The difference is in the detail for sure my man.
Thank you very much. We like your knowledge, skills, passion, and your smile.😊
What a great professional! Congratulations for all knowledge you have and thanks for sharing.
I've tried to explain electrolysis to so many people in and out side of automotive instances, and people are like.....wut? So when I heard
"the aluminum acts like a sacrificial anode and....gets all messed up"
it reminds me of all the tiems I started to explain electrolysis and, in the moment, realize I am about to lose my audience and need to keep it simple.
love Mike's explanations including both the laymen and in depth explanation for important concepts
Well Done!
Thank You.
Very informative video. Thank you for taking the time to make it for us.
Great stuff! I didn’t know about the surge tank.
Thanks for your service Mike been fallowing you since sr20forums
Great info Mike !
Thanks so much Mike! I'm a 60-something guy that's only got into tracking my car in recent years and every time I'm on the track I realize some modification I've made is not right, or not enough, and beside whatever I've done, I need more! So your vids are a great help. Thanks!!
I don't know why some people think every damn video is a product advertisement. You guys want me to just stand in front of an empty table with no visual aids all the time, get real, start your own channel...
hey there@@davconelectric , you sound like an arm chair wannabe "enthusiast." If you ever actually build a car for the track you'll realize there's a LOT of junk you can buy for your car. I appreciate that Mike gives some clues on quality products. If you wanna bitch and moan about product adverts, go ahead. But I'd asy your just a troll.
@@motoiq shots fired! You tell him buddy!
@@motoiqpoint taken
@@motoiq meanwhile i'm out here taking notes on what brands the real race cars use... that's like half of my research done right there! Thank you!!
Thanks so much for sharing all the valuable information that has always been kept secret we are so blessed nowdays. Always listen to your elders
This man must be protected at all costs!
Great info !
Great video! Very informative
A big hello from Australia , thank you so much for all your advise , will apply your recommendations onto my SR / 20 DET .
Most of the stuff on the table is going on an SR powered S13!
I hope you never stop making these types of videos, thank mr katt
Thank you
great video great advice
Well explained. Will apply these to my xr 6t. Thanks for info.
Wonderful information. Thank you
Thanks 🙏
Thank you sir!!
thanks you very much.
one of the best channel
Thanks!
This is such a good video.
I really like Gates green belts. I use them for my tow vehicle and also my supercharged f150z
Nice video and thanks for your hard work! I can't find a oil thermostat that goes past 180F? I would like to go a bit hotter? What do you think? Would that help with some issues using E85 and just have the oil last longer?
Pretty cool facts
Norma clamps is great!
Good stuff as always Mike! What is your opinion on heat shrink hose clamps (Gates power grip etc)?
I heard they work well but have no actual experience with them.
I just love mikes videos
I like how the ford FE engines in the Fairlanes and Galxies had the radiator expansion tank bolted straight to the thermostat housing above the block. Zero chance of the heads running dry due to elevation changes. There were plenty of cars during the 80s when their was a push for lower bonnet lines for reduced drag and better fuel efficiency that suffered from overheating and engine damage if the coolant level got low due to having the radiator at or not much abovethe cylinder head height, a risk that the other 98% of the population who arent petrolheads and treated their car as a simple appliance to take them from A to B everyday and didnt keep on top of maintenance.
Thanks lot
My eclipse probably needs a bleed. Temp guage only hits 1/4 fully warmed up at idle. Driving it goes to the 1/2 mark until stopped. Ill try jacking the front up, thankyou for the advice. Also iron block and aluminum head, thankyou for the heads up.
Great stuff and explanations. 👍👍👍👍
Not selling/shilling snake oil or miracle products, birthed by the marketing departments.
He is really good super smart
Great video, I overheated just seeing that global time attack car in the background 😜
Subscribed 👏😀
the g20 in the back 😍
🔥🔥🔥🔥🔥🔥❄️❄️❄️❄️❄️❄️❄️. Thx for the great info.
Big fan of certified OEM parts 🤔✊🏼
Thank you for another great video. I live in Japan, what Japanese coolants would you recommend here?
Honestly I have no idea, we have not tested any Japanese specific coolants.
Didnt know they had thermostats for the oil system thats awesome
He always look like he had strong bong rip b4 recording
Mike could be talking about how to unroll toilet paper and it would sound intriguing 👏😅
Get the Norma clamps with the integrated steel spring. It helps with thermal expansion and keep the pressure up.
Do you have a link for these?
@@louiC6Z NORMACLAMP® TORRO® that’s the name.
very true…❤😊
99 GC8 recreational car I use a racing tstat with stock radiator and stock radiator fans. I rewired my driver fan to a stand alone power switch and the passenger side fan activates like normal it turns on when Temps get 180d.
One better than the bleeder funnel is using one of those vacuum fillers. That way I can do a leak down test then flip a valve and pretty much fill the entire coolant system from there. That a Koyo radiator and using a swirl pot and high pressure cap on the pot and I haven't had any more problems with my G overheating at trackdays. That and I put in the Z1 oil cooler and got rid of the stock oil cooler (warmer?) sandwich plate.
I totally agree with you and we use one at the shop for known difficult cars like the RSX and the Z. This funnel is something that's cheap and makes a huge difference and everyone should use one!
+1 for the vacuum fillers. The NC miata is A TOTAL PAIN to bleed. The bubbles come out when they want to, not a second sooner. I'd have to drive in 1st gear at 6000 rpm around the neighborhood to finally push everything through. (Including the funnel, raising the car, revving, holding at 5000 rpm, anything.) Vacuum fill works every time.
@@TurboHappyCarThat's just God's way of telling you to k swap it.
@@ebf1003 Heeellll nooo. 😂 I'm completely happy with my ford fusion sedan engine that makes 50 hp less. 😅 My buddy k-swapped his NB and it had so many problems I don't think he completed a track day.
This man is nothing short of GENIUS.
I believe every word he speaks as gospel.
This guys knowledge is straight up brain ASMR
Great advice Mike! I use the same funnel. Do you have an opinion on Oetiker clamps? Thanks!
Supposed to be good but hard to service especially on a racecar.
Oetiker clamps are great. SeaDoo used them in the ‘90’s on the water hoses. The best part is that it gives good clamping pressure all the way around the clamping surface. Only downside that I see is that it is a one time use clamp.
Though, compared to worm gear clamp, the Oeticker clamp does not scratch your skin when working near it, or reaching beyond the clamp to access something else in the bilge, or engine bay in this case.
Hi Mike.
Referring to "tucked" radiator setups with AN hoses on a dedicated track car -- Any pros/cons in cooling / coolant flow when converting from traditional rad hoses (Larger Hose I.D) to AN-hoses (Smaller Hose I.D) + fittings?
On high-powered race, track, and drift cars other than drag racers, we have had lots of problems with those setups.
Pro!!!😊
Do you happen to know where you got that Stance water pump pulley for the SR, I can't seem to find it from Enjuku.
Great info here! I wonder what mods does the ae100 have🤔😂
stock beater
Is it better to use a 1.1psi in a semi modified car ( 4A carb with ported & polished head and lightened flywheel) with a spirited driving habit or just stick with stock spec of 0.9 psi? Loving your videos btw. Every vids are full of knowledge.
PSI or Bar? 1.1 is fine as long as the cooling system is in good shape with fresh parts just as stated in the video.
@@motoiq Sorry it's 1.1 kg/cm^2 (16psi). Noted on this. Thank you!
Been using Koyo aluminum racing radiators for years but the Australian company PWR has a track version that tests to do a better job specifically made for the track. Got one for my fk8. It costs more but it’s proven on the track.
They are very good radiators.
so underrated
Tell us about the green Camry in the back? Maintenance and suspension for a few topics?
Actually its a Corolla, bone stock, and 300k miles on it. It's Martins's beater, runs like a champ!
@@motoiq can you tell me anything about the 5s fe engine? Is there anything else besides maintenance that I can buy to squeeze out more reliability?
Hello, would you recommend a lower temp thermostat aswell? Thanks!
some times
Genius
Thank you for this knowledge. I like the 95 Corolla back there!
Swirl pot at the vent vs inline to the radiator. Why and ot when is it needed?
I’m afraid to skip your videos and miss out on some cool info
awesome
I have a 350z, so the underdriven belt doesn't affect the water pump due to the water pump being chain driven off the crank. But I have lowered temps with hood vents, header wrap, upgraded radiator, and Z1 oil pan spacer for extra oil capacity. All the small changes make a big difference, think i'll look into a swirl pot now since the car is virtually impossible to bleed lol
Used a vacuum bleeder too. The 350 is really hard to get all the air out.
