Sequential turbos

[PugLee]

I was just wondering if ive got the basic idea here right?

Theyre simple drawings but hey i done them on paint!







Obviously I havent included everything just trying to get the basic understanding right first

Any constructive critisism welcome

Thanks for the info guys! Im still trying to wrap my head around all this but I can understand how the larger turbo would create back pressure on the smaller one.

Would this setup be any better?

Surely when the larger turbo is up to speed it would mean the smaller turbo only takes away what it can? So wouldn't over spin?

Would anyone be able to point me in the right direction to get a check valve? I want to run 3" pipe work to the intercooler, so something of that size. A variable one would be the mutts nuts!

Cheers

Blow the small compressor THROUGH the large compressor, and use a simple flapper type passive bypass valve that opens to bypass the small compressor at high engine rpm


Alternatively, use a normal electronic throttle unit to blend the two together

Wouldnt the large compressor be limited by the flow capabilities of the small compressor? unless they each have their own seperate intakes?

[PugLee]

That looks more like a twin turbo setup... granted they come on at different stages but they seem to be the same size??

Ahh ok... thats makes sense.

Just came across this, almost identical to my revised setup...
