I appreciate that you took your time and spoke to me, though I might not understand exactly your thought process or what you have done yet, I may have seemed to have a difference of opinion, which wasn't really what I was intending, I myself watched as we went larger turbo last year and lost our spool up in the mid range but made huge power on the back end. I noticed at the track it seemed we lost our more usable 1st gear run up but gained more backend, which on this particular car I'd like to have the best of both worlds. On our other car an f series I took note we dynoed it with a vgt and I saw best of both worlds but understood we would never be able to make the top end power that the larger single setup made. So I'm just clarifying what and where I was coming from and that I applaud you for doing this and taking the time to communicate the theory and the outcomes you make with it. Less than 3 weeks ago I was contemplating the same idea due to last year's swap from t3 to t4 setup and the change we saw on our powerband on dyno. Thanks again! Humble4life
The way I understand it is that the turbo acts like a multiplier. It doesn’t care what the pressure(boost) is as the air goes in. It simply multiplies the boost. By using two turbos in this sequence allows you to achieve huge boost levels while keeping each turbo within its efficiency range, with minimal heat gain. More boost, less heat, more reliable.
Really good and interesting information. Not going to lie, struggling to understand you at times over here. Your speech speed is pretty fast and mumbly at times. No hate, just want to enjoy the content better. 🙏🏽
What are the limits of this setup? Could you use a turbo that is almost too small to get spool up super fast, or would said turbo bottleneck the bigger turbo? Would be crazy to start making a good amount of boost at 2,000 rpm. How did you go about sizing the turbos?
That set up is bunkers!!!!!!!!❤

What I was waiting for someone to do. Compound turbocharger🎉
That's exactly what I had in mind.So you relieve back pressure with the waste gate but not lose the energy

@33:31 respect!

It'd be nice to put an e gate between your boost side.So you don't choke down going through the small turbo
an eGate would add no benefit here.

The horsepower limit is the big turbo. 7175 is the turbo and it's rated for 1250HP. 1250HP is the limit.
Yes
Cause I'm dumb I didn't understand.
Air enters the big turbo first then the small turbo
Exhaust enters the small turbo first then the big turbo
Around what rpm do you begin making boost?
check his video before this, he explains how the rev range works, i forget the specifics. its not slow either
