Cool thing! On very simplified you think compound setup as you select HP turbo for the spool you desired and LP for the maximum power you want. And actually HP turbo does not give more air but it multiplies boost coming in from the LP turbo....for example you run LP turbo 2bar boost (PR 3 on sealevel) and HP turbo "1bar" (PR2), that gives you total pressure ratio 6 and on sea level it is 5bar minus atmosphere 1bar, so boost gauge say 4bar of boost. Optimum is to keep the load between the stages pretty even so overall effiency is good but that usually need some try and error. :)
This is so interesting! I would expect to see the small turbo feeding the big turbo, not the other way around. Excited to see this in the dyno and in action!
Best explanation is if you look at a jet engine it looks like an hour glass. Air comes in large and is compressed down, hot exhaust comes out of small and into bigger turbine
I've also seen two small turbos feeding one large so still get quick spool time but the pressure increase cause the two small turbos together are bigger than the one large turbo. Those setup are unreal. Pushing close to 100 psi and thousands of HP
@@alexsaam2696 But are we chasing pressure or airflow? Airflow makes power, not pressure. Compressor wheels have speed limits and flow limits, you can't feed a GT30 with a promod 108, it'll explode lol. Hence my confusion. I've only ever seen sequential turbos where the small feeds the big. Not the other way around.
Actually you could feed a gt30 with a 98 if you have enough wastegate to bypass it. You might not be able to light off the 98 but it certainly won’t explode it. I feed gt30 with a g42 1200 and it works great.
I think it was Shawn I was watching a video he did on 4cyl's he said it was possible to get 3000hp using a compound turbo setup, 120lbs+ boost but I'm sure there's a lot to figure to get to that point, so I'm very curious to see how good this works for you guy's, that 2jz is just insane! Hold on to the record!!!!!
Saw bragers racing just dropped a compound setup on their Instagram page as well. 2jz world just got even more interesting. 3000hp compound turbo setups seem to be the "new setup " going fwd
Wish you’d make more YT-content! This project is so cool. Been following the “Stick shift battle” all the way from Sweden for a couple of years now. So impressed by you top guys. Good luck if you make it to FL2K 👍
I'm excited to see more Gas engine compound setups. That has been under developed compared to the diesel side of boost, so I'm really looking forward to how the development goes.
Wouldn’t the little turbo choke after it’s boost limit? Plus how much more will it weigh? Really excited to see how this one plays out. I really hope we see a new PB
I have the same question regarding the little turbo. I’ve seen similar setups but the little turbo would feed the big turbo and the big turbo would be feeding the intercooler/intake manifold. Definitely interested to see how this works!
Seeing as the air is pretty hot it is not dense at all. I run 55 psi on a 4 cylinder using a g42 feeding through at gt30 that only has a 2” outlet. Has not been an issue
Beautiful. I will never complain about back purging a couple joints ever again after seeing all that titanium pie cut work that would need back purged. Wow.
Beautiful whats the tuning strategy going to be? In regards to when do you know to which from the smaller turbo to the bigger turbo. Turbo Shaft speed? Engine rpm or boost or back pressure ? Would love some insights on how that would work
Excellent setup. My only concern would be when the large turbo is at full power, will it over spin the small turbo? I hope you can monitor this parameter at the dyno.
Small turbo will be very safe with that much wastegate to bypass the exhaust. I run mine in gate pressure for the small turbo and control ultimate boost with the large turbos gate
@@136videos if anyone can it’s these guys, but a compound turbo setup like this being consistent would be pretty revolutionary at the numbers these guys are going for. I’m along for the ride though :) lol Id like to hear more about the clutch setup as well.
Good job man! I don't know much about turbos other than watching RUclips, the question is, since the engine making enough power for the smaller turbo, will the larger turbo over spin the smaller turbo and make it go bad? Thanks for sharing your work!
Love the compound boost, I do it with a large turbo feeding a small supercharger on a 1L engine. The twin gates below the small turbo is really cool idea. Lots of exhaust flow happening so it's hard to say how it will all work. Remember the large turbo will be helping the small turbo spin so it will need less exhaust so it may be more efficient for the exhaust to go through the small turbo then the gates. Super curious how it all works out! Amazing fab, all the welds look exhausting (pun intended) :)
looks awesome Joel, I've always wondered what EMAP readings look like on these setups and what if any changes occur measuring on the first turbo up-pipe vs. the 2nd turbo up-pipe.
Nice to see I have a compound Mitsubishi fox body myself. Look forward to your results. I just use the small turbo on gate pressure to simplify it. Only running mid 50s boost though.
Seems like ALOT of extra weight with extra : brackets, WG, turbo, WG, dump pipe x2 more SS tubing. Maybe 45lbs compared against a single setup. But if it significantly quicker than a single turbo build, maybe your on to something…..
Looks like a newer model of SpaceX. Someone's quest seems to be the first car in outer space 🌌. Elon Musk who!!!! Lol.... Dude forget about making some Jam. This things about to create a whole new species of POWA.😂🙌🏁💯⭐🔥🔥🔥🔥
Jarvis is the first one I seen do really well with a compound setup on a smaller motor. Took his K powered S2K deep into the 4s with a similar setup. Definitely think we’re gonna see a lot more cars done this way.
I'm stoked to see racers like yourself give compounds a shot. They've been popular in diesel performance for a few decades for their high boost demands.
It is simpler to divert as much exhaust gas to the big turbo as possible and take the small turbo out once the big one is spooled, running it more like a sequential how you were describing, but that does also eliminate one of the big advantages of a compound turbo system. It probably isn't relevant here, but on smaller engines especially, one of the huge benefits is the ability to balance the pressure ratios between both turbos and avoid surge. You may be able to run a massive amount of flow on a 2.0L engine, for example, that'll ultimately end up being a 5:1 pressure ratio and would experience horrible open throttle surge if you ran only the big turbo. By using a compound turbo system, you can have both turbos running at a 2.24:1 pressure ratio to equal a 5:1 ratio at the manifold, but both turbos are kept in the middle of the compressor map and you avoid surge altogether.
You get compounds cuz your big turbo can't efficiently move the volume/mass of air you want, so adding the little turbo increases potential pressure ratio. And having two turbos for different engine speeds, of course, but you were pretty clear on that part Have you thought about wrapping the exhaust? That's a lot of exposed exhaust pipe underhood and near other components, let alone how long that run is to the primary; you're losing at least a little efficiency there, which could be the difference between winning and losing as I'm sure you already know
You will lose power up top at the same boost level, that's because the primary induction will be providing all of your air flow. It will increase your torque curve down low all the way up to the boost level you were running, but when you get to that level, the airflow, or rather the efficiency of the big turbo will be lower, because it will be at a lower P/R individually than it was by itself. There are two ways you can get around that. Run more overall boost or get a bigger primary induction (big turbo). You want a primary induction that is at the right efficiency for the P/R that it is running by itself before going into the smaller turbo. Also remember that the P/Rs are multiplied, not added. Think of it this way. The smaller turbo is just running using much denser air. So whatever the bigger turbo is doing with the air, the smaller turbo is treating that air like it's ambient. If it's a 2.0 P/R on the big turbo, the little turbo will be doing what it normally does times 2, but that's not taking into account the hotter compressed air from the primary turbo.
Dumb question, but for boost during shifts, why couldn't a turbo just feed through an airtank constantly, when ignition cuts the tank dumps to maintain boost? Something of that sort? One air tank is less complicated than 2 turbos, ice water in the trunk, all the other stuff people do just for .2 of a second.
So I designed built and race a compound bike and not having an intercooler between them is dumb. We run anywhere from 35-90ishpsi depending on gear ect and were talking 100s of degrees difference having two cores over just the one. Space and weight are huge for us so to bite the bullet and add the second core and ducting ect had to really be worth it and it was a good 30% we left on the table until we realized and were on e85 chilled with dry ice to -80°f on a blow through carb setup and it still made a huge difference for us. Now I'm limited by turbo size so my efficiency is pretty shit by the time I get both into the 3bar range so its exacerbated but I think you might consider it. The efficiency of the primary turbo goes down the drain fast once its getting preheated air.
IMHO While spooling the small turbo will face shocking due to inlet feed rout, while the big turbo start pushing air will face restrictions due to small turbo housing, would be better ideal if it stage RPM base setup with gate switching. Good luck though
*So in layman terms... The big turbo feeds the little turbo, the little turbo releases the extra compression back to the big turbo. Like 2 Brothers pushing each other to go first???*
If you use the turbos the other way around , big feeding the small turbo, I know it sounds backwards , but it works better. The big turbo feeding the small makes it so even when the big turbo isn’t spooled up fully because it pushes more air , the small is constantly spooked and in turn gives you no lag. Once the small reaches its limit have an electronic valve redirect the air away from the small and into the intercooler from the big itself .. you will get the benefits of no lag and massive top end power with only 1 more section of pipe and a electronic valve… you can use a turbo smart straight gate as the valve and they flow and work perfectly .. anyways it’s a sick build either way and I’m definitely subscribing and staying tuned to see what else you guys do
You really would benefit from an intercooler between stages. Like, a lot. Just do an air to water for packaging. Bob Norwood wrote some good books that have all of the maths.
Be interesting to hear what the shaft speed of the little turbo does when the big girl starts wailin.. This kinda experiment really gets the cogs turning in my head. Stunning bit of kit fellas.
For the waste gate controller should the boost be equal to both turbos or no problem to have different boost like for example for the small turbo i make it 2 bar and the big turbo 3 bar it will work fine or should make both same ? Because i want to do it for my turbo patrol All the best in the new turbo setup 👏🏻
I'm sure this might be proprietary but how is the boost control setup ? and what size is the small turbo ? is it like a 66 or a 70? Are all the gates set to the same pressure or something like 30 psi for the little turbo and 60 psi for the pro-mod ?
so do the two wastegates feed into the exhaust after the small turbo to help spool the big one even faster? or do they just dump exhaust because that kind of seems like the drive pressure in the header would be high enough to overcome the drive pressure into the big turbo and help spool even more and then the dump on the big turbo could just eliminate pressure anyways
Straight through butterfly waste gates off the small turbo manifold would likely perform better at top end than the popet type waste gates due to less pressure drop.
I've always seen the smaller turbo feed the bigger turbo. Wouldn't that make more sense? I'm not too familiar with compound turbo setups, except what I've seen on tractors.
What is a super awesome ride, now honestly I don't know what to say about what you're doing, just be prepared to be somewhat disappointed, honestly I don't think it's going to turn out how you guys are expecting, there's a reason why you don't see anybody else out there doing this..... sure it looks cool but it's not practical. It's actually a step backwards but some people just have to learn for themselves. That's a great platform I wish you guys the best but in reality you should have just put a monster turbo or twins and made your 1,500 + horsepower and it would have been practical and reliable, done. Haven't seen this car anywhere so you guys are still nobody's. And if your shit works??????? we all should be seeing that car in the race car world soon.....yeah good luck🙄
Beautiful work but looks like a good bit more weight, i guess with that amount of power the boost recovery and midrange HP outweighs the mild weight addition
its a 3 liter engine - its almost half the displacement, and making 400hp+ per hole. There is no reason to compound a 5L v8, that displacement advantage makes a big difference in getting the turbo spun up.
Hollow out a big pod filter and put it on the pipe between the two turbos so you can't see the huge turbo up front! 😂😂
Bro that thing sounds AWESOME! Looks great too! Good luck at FL2k and see you in a few weeks at WCF!

that's a lot of stuff under one hood! I favor bench testing before going through the hassle of fitting everything but I'm not a welder dude either so?
Can't wait for testing!!!!! Awesome job guys!
What sort of boost psi are you looking to make? And inlet temps?
This isn’t ideal to be ideal he’d have a intercooler and aftercooler
I've always seen the smaller turbo feed the bigger turbo. Wouldn't that make more sense? I'm not too familiar with compound turbo setups, except what I've seen on tractors.
Intercooling between the 2 turbos will help a bunch ;)
Pie cuts are nice, but weld beads disrupt airflow.

You talk that talk with condidence bro.
Beautiful work but looks like a good bit more weight, i guess with that amount of power the boost recovery and midrange HP outweighs the mild weight addition
awesome!!! how difficult is the tunning now?
love it keep the good work and new set ups hope you break some records!!!!
Why don't you run methanol and get rid of that intercooler!
I have been a fan for so long and your still under 10k subs .. people need to know more of you Mr. G
How come your running a intercooler ? You not running meth ?
Awesome set up i wanted to do this on my drag car supra but you beet me 2 it lol
Ash
Welcome to the compound club boys ❤🎉
I love this build🔥🤩
I thought it was supposed to be Lil turbo feeds the big one
Big up yourself Mr Grannas
Make sure you have enough fuel rail for the whole pass.
Sweet setup, but thats a lot of work to beat a cast block single turbo old tech/school engine.
its a 3 liter engine - its almost half the displacement, and making 400hp+ per hole.
There is no reason to compound a 5L v8, that displacement advantage makes a big difference in getting the turbo spun up.
Maybe a little nos for cooling?
but if you do add nitrous...........
I'll be looking forward to this beaut.
That’s what I call “compound interest”; great investment right there.
Cant wait , its gonna be lit 💥💨
