😂😂😂 we did do a basic tune and several warm up start up tunes and that test drive was supposed to be a chill start to the tuning so we had data under load…. Unfortunately Dylan only has one setting 😂 WOT.
@thatjdmkid8170 probaly the opsite with the new injectors I've seen this before when the injectors are to large for a stokeometric rate at idle or low rpms. But your analysis might be correct as well. Sounds like wot due to turbo and supercharger being to close.
@@CountDrankula0o0no compression probably means good chance it ran lean and melted a piston. A tune would have helped prevent a lean condition. I'm looking forward to seeing where this goes. Hopefully the rad lads can scrape together enough funds from merch sales to get it going.

Just discovered you guys a little while ago and I love that you're having fun and not just destroying shit for views like a lot of other channels now days.
It's actually unreal what you guys can do by yourselves in a garage. Gav gotta be world champ at tetris after this. This was so much fun. I straight up felt excited once it turned on, can't imagine what you guys felt
Love the Death Metal Miata build I had to get a shirt after seeing how fucking bummed you guys were after working on this car and I feel the pain!! I've seen too many project cars blow on this website and I desperately want this car to make it longer than 1 day of driving in the current form. Looks Rad and sounds rad and I hope getting a sweet shirt from you guys makes you feel a bit better :D Stay Rad \m/

You guys are having too much fun 😂 On a serious note, when twincharging you run them the other way around, the turbo should be fed by atmosphere and feed into the supercharger, your total airflow is limited by the first thing in the chain, same reason compound turbos use a large turbo feeding into the small one

I really enjoy your video’s. I am not the type to ever comment on videos but felt I might add in some thoughts to consider as I have done a setup like this in the past and had to learn the hard way with damaged turbos. To find out that turbos generally don’t like to have a lot of vacuum on the intake side causing The bearings to fail. Sure before the turbo spoils it will have positive pressure on the inducer but once it starts to flow more than what the supercharger can flow it will be well within a negative pressure.Again I enjoy your videos and offering maybe some food for thought.
Definitely good to know. We do plan to add some type of valve in between the super and turbo that opens up around 5k. We were just hoping to get it to run for a bit first. Appreciate the thoughts 🤘🏽
@@RadFactoryGav Oh Brother, just wanted to say i've done some sketched out stuff with boost my self over the years... if you want to do BOOST you NEEEEED methanol injection! it does two very important things. it provides extra cooling like an intercooler only better! AND it provides detonation resistance due to the cooler burning and slower burning methanol. aslo known as windshield washer fluid injection :D I used a old mid 70's car windshield washer squirter to really add a boat load of water/methanol into my extremely over boosted 88grand am 2.0L. just have it come on under boost and your ready to go! ps you can fine tune it by sqeezing the end down a bit or just buy a kit with some very large sprayer nozzles. its *almost* like you cant add too much lol.
It's not that one can't run the blower into the turbo it's that in almost all cases you wouldn't want to do that. The thought is that the blower is not a very good compressor at real pressure ratios but the turbo is so you use the blower to feed enough boost to the engine that it acts like a bigger engine and spools the turbo quickly. It does work well. Now on banks pikes peak semi they did it the other way because the turbo they need to run is huge and the atmosphere is thin and it's a diesel. They don't throttle with air but fuel and that means the egts are also low off throttle so no energy to keep the turbo in speed. Feeding the blower through promises a minimum of let's say 30psi already in the charge pipes and intercoolers meaning when they get back on the throttle they can jump into enough fuel to make some power without melting anything due to high egts that extra boost air in a diesel is to cool combustion not to make the actual power if you will. You have a gas engine a Mazda bp series from what i can see. I'd love to see a cheap m90 feeding the engine and a gtx2876 feeding it. I think youl find no lag but keep in mind from a compound turbo guy if that blower is set up to run 1bar or 15 psi and the turbo is set to the same 15psi you won't get 30psi in the engine youl get 45psi 😅 you have to multiply the pressure ratio not add the psi. Given the injector sizes that won't live one gear 😂 and given the boost you need e85 or meth to have a chance I'd start with a standalone and 8 injectors a set that you have and a set of 2200cc to come in with boost
In regards to exhaust, if y'all get this thing going well and enjoy it, i think itd be worth redoing all the mounts and relocate everything for 'practicality', then do a standard exhaust setup :)
Keep going guy's you've got this. Do anything to keep going mug some old lady's 😮only joking you guy's are cool and this channel could blow up ✌🏻🏴
You would have better results if the turbo was before the supercharger. With twin charging you always want the larger unit first, that way it can flow all the air needed, provide some boost, and then the smaller unit further compress the charge. Basically if you are not force feeding the small supercharger (good for 150hp) it can’t flow the 350hp the turbo is capable of
The typical way to plumb a compound twincharged system is: Air filter/maf/bov/turbo/throttle body/supercharger/bpv/intercooler/manifold You can even go as far as to use the supercharger bypass valve to shut off the supercharger and let the turbo take over for increased power to the wheels. I did this by using an aux channel on my boost controller that opens a solenoid that supplies vacuum to the bpv actuator, works good for valet mode too because the turbo spools very slowly without the superchargers assistance.
You guys are awesome very underrated Chanel I’m currently doing a fb market place wrx build restoring the entire car trying to his 400hp with 10k you guys got this
Need a y split with a electronic gate or at least a one way valve for the turbo intake so it can bypass the supercharger when it’s spooled up. As it stands the whole system is limited to the air the SC screw can move. Ideally you want a magnetic clutch on the SC so it can engage and disengage when needed. To go the cheap route you could make a manual hydraulic clutch for it.
No you don't, that would be twin charged, what they have there is compound charged, the only thing I don't see in the setup is a supercharger dump valve. I have a twin engined Volvo, both with superchargers and turbos, the setup is very similar to this.
@@claymore2k1T10 in terms of performance, do you not understand that the supercharger becomes a bottleneck when the turbo is spooled without a way to completely bypass it and remove the parasitic loss? If all the air still has to route through the SC then you are limited to the air the SC can move and nothing more making the turbos just cool noise makers
I like your channel a lot. I have one suggestion. You in the pink shirt. When you are calmer and more genuine it seems much better. But when you add excitement that isn't natural, it is off putting. Just be yourself and that is much better my friend. Such as when you are explaining that there aren't big chunks in the motor. You are way more easy to listen to and entertaining. It could just be me but when you are "acting" more excited it just comes off as disingenuous and you don't have to do that at all my friend. You guys are totally entertaining as yourselves. Good luck ok the miata adventure and i hope you guys continue to grow. Good stuff here.
Don't you need some sort of valve for the turbo intake to be able to feed itself from the atmosphere when the supercharger can't supply the air volume the turbo can suck at high rpm ???
Technically yes, however most people we have researched did that as a second stage, just running it without that extra stuff first. The goal is to do that eventually
Love it! It sounds lean at the top end with possibly the valve timing being off? I dunno, it's a start of the engine with twin charging, tuning is always needed. I like what other commentors said about the o2, idle would be helped with tuning at speed because possible backflow will get worse at higher speeds thanks to wind speeds. A cover or a exhaust pipe heading down will help that. I have to go with gavin on that lol. With 0 compression it could be a head gasket failure, which can happen thanks to high heat and boost. Which could mean too lean but also the boost air wasn't cooled enough as well. Maybe some water injection? Or water methanol? Helps with lean out, but also you have another pump and some other injectors! Anyways, he was saying it was a hot day so it's why I'm "leaning" that way lol. If it turns out it's not any of that, it could be a combo of things. Spark plugs loose, compression rings went, hydrolock from too much fuel from o2 sensor thinking it lean. Like others said. Or valves becoming stuck as well. Unfortunately a good tear down and once over will probably help the most. Side note, from this edit after reading some comments. This is something I noticed too, but typically you would have the super charger feed in from turbo because at lower rpm and lower boost they are pretty okay. The compressor of a turbo becomes more effective & efficient at higher RPM and higher boost. It won't harm the supper charger. But! While I would love to see it, I know how much work that is to a degree. So it might not be considered worth it unless you wanted to push that boost up and drop temps from it. I hope you figure it out and still have fun with it. Love the content.
All good points!! We definitely learned a lot with this first attempt. The O2 is why I want to build a proper exhaust lol. We also want to build a secondary intake for the turbo to get extra air once spooled. There is a guy with a sweet Saturn sky with a version of this set up that we are trying to base the build off. Thank you so much for the support!
Oh for the next Miata build see if another chan or somone can help you all out since this refresh left you all wanting and hopefully next time you guys can find some extra help and making building this thing a bit easier
Im building a twincharged lancer. Im pretty certain the turbo chould be feedibg the supercharge not the way you guys have it. Roots style blowers multiply a fixed amount of air pet rotor per rotation; it will be a restriction for the turbocharger when trying to "pull" more air than the fixed amouny of air supplied by the supercharger.
The next step for us was to build a second intake for the turbo to pull more air from at high rpm. Based on a very cool build some guy did with a Saturn sky.
I think some valve between supercharger and turbocharger should be installed to let freeflow air into turbo when that spooled up (valve controlled by RPM or/and pressure by ecu). Or check is it positivie pressure present between supercharger and turbocharger to make sure that supercharger is not choking turbo when it spool up. Supergarger with electric clutch sould free up some power when turbo takes up boost generating.
Just to add, you probably should have the turbo first in line, allowing it to pull in as much air as possible before feeding that to the supercharger as the supercharger will only flow a specific amount of air related directly to the speed at which it is rotating, which then won't allow the turbo to do anything as it will create a vacuum between its inlet and the outlet of the supercharger
I think you need to make the gab ring bigger, when the boost is high, the engine will be hotter, if the gab ring is too close, the piston will break easily, because the piston ring has expanded and meets end to end of the ring
you have done the twin charging backwards, the turbo inlet is meant to be open to the atmosphere, the turbo outlet goes into the inlet of the supercharger and the supercharger goes to the intercooler.
This is awesome. Sucks that it blew but it definitely needs to be tuned. Not sure what you guys are running for engine managment if anything at all, but you should really consider a microsquirt ecu. They're on the budget end of Standalones but are still very capable. Also, has an engine swap ever been considered for this build? A 2.0/2.3/2.5 Duratec/MZR swap would be a great budget option. The 2.5 unopened is good for 350-400hp and they can be had for fairly cheap. For a trans a good option for that miata would be the 2004-2015 miata NC 6 speed, they came with a 2.0 duratec. Awesome content, keep it up!
You might want to relocate the O2 sensor closer to the turbo outlet because under low flow conditions fresh air can back flow and give the computer a lean condition causing it to add a bunch or fuel. If my the above is true it could have been a hydro lock due to a bad o2 signal.
tuning and ring gap is importiant, when it cuts like that under load its normally from not enough fuel, not enough fuel = lean burn, lean burn = heat, heat = pinched ring, pinched ring = kaboom
I'm just gonna agree that more tuning before any spirited test drives is probably necessary for longevity (meaning more than 2 around the block test drives😂). It's trying to relearn idle much like my subaru it seems, technically the correct procedure for that is to let it idle for like 30-45 minutes (technically with A/C full recirc but I don't) and restart. Or the quick way, spirited driving (NOT YOU plz😂) with downshifting down to 2nd during stopping. Also, we saw the bottom end didn't get hurt before new testing, but how well was the top end gone through? Just saying, a chunk of plastic could be in one of cylinder 4's valves (the true final bit filter), or the bad timing whilst trying to recover from the stalling when it does the "I'm dying, I'm almost gone, good bye, gurgle gurgle clunk gurgle, ROAR from 30 to 3k rpm with an immediate p0420 code if I don't catch it early enough in the stall. A similar set of circumstances could result in a bent valve as well in your situation with all them BARS! Psi that is, ideally you just drop in a new valve or two and retry slower? Although booms can get them views so you do you, but however long it takes many of us are emotionally invested although just like you apparently not well financially sturdy. Take the time, take the care, dust yourself off and try again, we'll be waiting with baited breath. You guys rock! Ps. It took me a week of bus taking and uber rides to finally figure out my suby wouldn't start because the + starter wire was broken but only the internal metal wire & not the outer sheath so visually it was fine until I accidentally knocked it with my rachet and it just came fully loose and saw the lack of copper connection. Now she runs like a... well a 250k+ 07 manual forester do 😂 Good enough to find out 😁
!!!!!!!!!!!!!!!!!! I have thought about doubling up for yeeeeears!!! I fucking love this, yall. Tks. All the *cool* car guys always sht on the idea, but they are obv all punks. (Plus Empiricism means we build up our own Theories by shtting on other's Theories, rather than bolstering our own Theories)
An interesting compound setup to say the least, i have run a twin charged setup before but bypassed the supercharger at certain rpm to only run on the turbo but what your doing isn't impossible but need a good way to manage the boost an as others say a good tune....The saying why not right :)
It’s pretty quick, makes 20psi by 3500 and 30psi by 4500. With practically no back pressure! I may swap to a smaller gt35 but I’m afraid it would spool too fast and huck a rod lol
Dear Rad Factory, i don't want you to fail this, so i'm just going to say it. That'll not be the best use of those parts. You need to make sequential. This has already been on a few "factory" models, the Nissan March Super Turbo comes to mind. That model have a cult surrounding it, which means there's lots of forums with useful info on setups and tuning. Good luck
@The Rad Factory now use a turbo on exhaust at back of car let exhaust flow strait through turbo use compressor side to feed stainless steel exhaust tube with rocket nozzle and feed with oxygen and diesel fuel or propane or whatever fuel
Remember, build, THEN tune, then test drive. Not build, test drive, break it, fix it, tune it.
😂😂😂 we did do a basic tune and several warm up start up tunes and that test drive was supposed to be a chill start to the tuning so we had data under load…. Unfortunately Dylan only has one setting 😂 WOT.
You need an AFR gauge for any turbo build especially befor doing any pulls before a decent tune I wonder if it went lean and melted a piston or ring

You have to be especially stupid to hit wot on an untuned boosted engine
If yall could actually get good tuning before doing full throttle pulls I can promise you they won’t blow up your just asking for it to blow

Yeah at least a hacky boost reference fuel pressure or something would probably help self destruction. Long term? Still probably kaboom...

Need a y split with a electronic gate or at least a one way valve for the turbo intake so it can bypass the supercharger when it’s spooled up. As it stands the whole system is limited to the air the SC screw can move. Ideally you want a magnetic clutch on the SC so it can engage and disengage when needed. To go the cheap route you could make a manual hydraulic clutch for it.
That’s the goal!!
@@RadFactoryGav that’s awesome! Can’t wait to see it come together
No you don't, that would be twin charged, what they have there is compound charged, the only thing I don't see in the setup is a supercharger dump valve. I have a twin engined Volvo, both with superchargers and turbos, the setup is very similar to this.
@@claymore2k1T10 in terms of performance, do you not understand that the supercharger becomes a bottleneck when the turbo is spooled without a way to completely bypass it and remove the parasitic loss? If all the air still has to route through the SC then you are limited to the air the SC can move and nothing more making the turbos just cool noise makers
what a nice project
I like your channel a lot.
I have one suggestion. You in the pink shirt. When you are calmer and more genuine it seems much better. But when you add excitement that isn't natural, it is off putting. Just be yourself and that is much better my friend. Such as when you are explaining that there aren't big chunks in the motor. You are way more easy to listen to and entertaining.
It could just be me but when you are "acting" more excited it just comes off as disingenuous and you don't have to do that at all my friend. You guys are totally entertaining as yourselves. Good luck ok the miata adventure and i hope you guys continue to grow. Good stuff here.
Underrated channel
Appreciate that!
Don't you need some sort of valve for the turbo intake to be able to feed itself from the atmosphere when the supercharger can't supply the air volume the turbo can suck at high rpm ???
Technically yes, however most people we have researched did that as a second stage, just running it without that extra stuff first. The goal is to do that eventually
Love it! It sounds lean at the top end with possibly the valve timing being off? I dunno, it's a start of the engine with twin charging, tuning is always needed. I like what other commentors said about the o2, idle would be helped with tuning at speed because possible backflow will get worse at higher speeds thanks to wind speeds. A cover or a exhaust pipe heading down will help that. I have to go with gavin on that lol.
With 0 compression it could be a head gasket failure, which can happen thanks to high heat and boost. Which could mean too lean but also the boost air wasn't cooled enough as well. Maybe some water injection? Or water methanol? Helps with lean out, but also you have another pump and some other injectors! Anyways, he was saying it was a hot day so it's why I'm "leaning" that way lol. If it turns out it's not any of that, it could be a combo of things. Spark plugs loose, compression rings went, hydrolock from too much fuel from o2 sensor thinking it lean. Like others said. Or valves becoming stuck as well. Unfortunately a good tear down and once over will probably help the most.
Side note, from this edit after reading some comments. This is something I noticed too, but typically you would have the super charger feed in from turbo because at lower rpm and lower boost they are pretty okay. The compressor of a turbo becomes more effective & efficient at higher RPM and higher boost. It won't harm the supper charger. But! While I would love to see it, I know how much work that is to a degree. So it might not be considered worth it unless you wanted to push that boost up and drop temps from it.
I hope you figure it out and still have fun with it. Love the content.
All good points!! We definitely learned a lot with this first attempt. The O2 is why I want to build a proper exhaust lol. We also want to build a secondary intake for the turbo to get extra air once spooled. There is a guy with a sweet Saturn sky with a version of this set up that we are trying to base the build off.
Thank you so much for the support!
Hell yeah. Another cool video guys!
Thank you!!
Thank you!!
Love that you guys are still going even broke.. keep it up 👍
Haha we’ll always find a way!
Oh for the next Miata build see if another chan or somone can help you all out since this refresh left you all wanting and hopefully next time you guys can find some extra help and making building this thing a bit easier
Im building a twincharged lancer. Im pretty certain the turbo chould be feedibg the supercharge not the way you guys have it. Roots style blowers multiply a fixed amount of air pet rotor per rotation; it will be a restriction for the turbocharger when trying to "pull" more air than the fixed amouny of air supplied by the supercharger.
The next step for us was to build a second intake for the turbo to pull more air from at high rpm. Based on a very cool build some guy did with a Saturn sky.
Yes I’m this
@@claudedottin1312”I’m this”
What???
@@fastinradfordable 😂 hol up lemme cook
I think some valve between supercharger and turbocharger should be installed to let freeflow air into turbo when that spooled up (valve controlled by RPM or/and pressure by ecu). Or check is it positivie pressure present between supercharger and turbocharger to make sure that supercharger is not choking turbo when it spool up. Supergarger with electric clutch sould free up some power when turbo takes up boost generating.
We were thinking of adding a second blow off valve lol
Just to add, you probably should have the turbo first in line, allowing it to pull in as much air as possible before feeding that to the supercharger as the supercharger will only flow a specific amount of air related directly to the speed at which it is rotating, which then won't allow the turbo to do anything as it will create a vacuum between its inlet and the outlet of the supercharger
I think you need to make the gab ring bigger, when the boost is high, the engine will be hotter, if the gab ring is too close, the piston will break easily, because the piston ring has expanded and meets end to end of the ring
The rings were gapped for boost idk if that was the issue.
i love yalls stuff keep it up and im totally coping some merch
appreciate you!
you have done the twin charging backwards, the turbo inlet is meant to be open to the atmosphere, the turbo outlet goes into the inlet of the supercharger and the supercharger goes to the intercooler.
We have seen it both ways
Definately turbo into the charger
Still nonetheless great job and amazing determination don't give up you got an incredible toy coming together
Thanks! We will get it working!
This is the turd merger lol. Awesome!!!!
😂😂
Always a Rad day when you guys upload!!
Thank you!!!
🙌🏽🙌🏽
This is awesome. Sucks that it blew but it definitely needs to be tuned. Not sure what you guys are running for engine managment if anything at all, but you should really consider a microsquirt ecu. They're on the budget end of Standalones but are still very capable. Also, has an engine swap ever been considered for this build? A 2.0/2.3/2.5 Duratec/MZR swap would be a great budget option. The 2.5 unopened is good for 350-400hp and they can be had for fairly cheap. For a trans a good option for that miata would be the 2004-2015 miata NC 6 speed, they came with a 2.0 duratec. Awesome content, keep it up!
Definitely on a standalone, I forget which one.
20:56 is engine start
You might want to relocate the O2 sensor closer to the turbo outlet because under low flow conditions fresh air can back flow and give the computer a lean condition causing it to add a bunch or fuel.
If my the above is true it could have been a hydro lock due to a bad o2 signal.
tuning and ring gap is importiant, when it cuts like that under load its normally from not enough fuel, not enough fuel = lean burn, lean burn = heat, heat = pinched ring, pinched ring = kaboom
We shall see! We are pulling the head this week and doing an autopsy
I have to admit, I found exactly that the hard way myself 👍
I'm just gonna agree that more tuning before any spirited test drives is probably necessary for longevity (meaning more than 2 around the block test drives😂). It's trying to relearn idle much like my subaru it seems, technically the correct procedure for that is to let it idle for like 30-45 minutes (technically with A/C full recirc but I don't) and restart. Or the quick way, spirited driving (NOT YOU plz😂) with downshifting down to 2nd during stopping.
Also, we saw the bottom end didn't get hurt before new testing, but how well was the top end gone through? Just saying, a chunk of plastic could be in one of cylinder 4's valves (the true final bit filter), or the bad timing whilst trying to recover from the stalling when it does the "I'm dying, I'm almost gone, good bye, gurgle gurgle clunk gurgle, ROAR from 30 to 3k rpm with an immediate p0420 code if I don't catch it early enough in the stall. A similar set of circumstances could result in a bent valve as well in your situation with all them BARS! Psi that is, ideally you just drop in a new valve or two and retry slower? Although booms can get them views so you do you, but however long it takes many of us are emotionally invested although just like you apparently not well financially sturdy. Take the time, take the care, dust yourself off and try again, we'll be waiting with baited breath. You guys rock!
Ps. It took me a week of bus taking and uber rides to finally figure out my suby wouldn't start because the + starter wire was broken but only the internal metal wire & not the outer sheath so visually it was fine until I accidentally knocked it with my rachet and it just came fully loose and saw the lack of copper connection. Now she runs like a... well a 250k+ 07 manual forester do 😂
Good enough to find out 😁
You guys have a lot fun , it fun building crazy shit !
Glad you enjoy watching it! Lol
And also that sounding like it doesn’t wanna start was it being down a hole if it don’t turn smoothly then it’s blown and or hurt
Exactly! Was not surprised to see cylinder 1 not getting any PSI
Great stuff!
Thank you!
Went from the rad factory to the sad factory
😂😂😂😂
it's actually better to feed the compressor with the turbo
We have seen it both ways, it’s uncharted waters for us either way lol
!!!!!!!!!!!!!!!!!! I have thought about doubling up for yeeeeears!!! I fucking love this, yall. Tks.
All the *cool* car guys always sht on the idea, but they are obv all punks.
(Plus Empiricism means we build up our own Theories by shtting on other's Theories, rather than bolstering our own Theories)
Glad you liked it! Hopefully we will have it running proper soon
Love this series 🤘
Thank you so much!!!
@@RadFactoryGav hope you guys can get it going again 👍
👍
This is kinda what I'm about to do with my Harley. Just not with a $300 supercharger or turbo 😂
Harleys are already crazy powerful that would be nuts!
@@RadFactoryGav I'm a large person... I need the HP and torque 😂
An interesting compound setup to say the least, i have run a twin charged setup before but bypassed the supercharger at certain rpm to only run on the turbo but what your doing isn't impossible but need a good way to manage the boost an as others say a good tune....The saying why not right :)
Down pipe for sure, im over hood dumps.
One of us! One of us!! 😂
When I see hood dumps it makes me think of the sweet smell of burnt clutch ,blow-by vape juice, and black ice air freshener....
Insane amount of power🤣🤣🤣
I have this exact idea for my rsx you’re just older and got to it first but thanks now I know what not to do and mine won’t be budget😈
More budget definitely helps!
The Turbo should be feeding the supercharger
If you guys have any questions hit me up. I have a twincharged Sti engine m90/gt45, so I’ve done a lot of research on how to make it all work.
Heck ya! That sounds like it would be crazy fast!
It’s pretty quick, makes 20psi by 3500 and 30psi by 4500. With practically no back pressure! I may swap to a smaller gt35 but I’m afraid it would spool too fast and huck a rod lol
Dear Rad Factory, i don't want you to fail this, so i'm just going to say it. That'll not be the best use of those parts. You need to make sequential. This has already been on a few "factory" models, the Nissan March Super Turbo comes to mind. That model have a cult surrounding it, which means there's lots of forums with useful info on setups and tuning. Good luck
@The Rad Factory now use a turbo on exhaust at back of car let exhaust flow strait through turbo use compressor side to feed stainless steel exhaust tube with rocket nozzle and feed with oxygen and diesel fuel or propane or whatever fuel
😂😂😂😂😂😂
