Doesn't work that way Frank. Better go back to boost math 099. Chatmanr is on point.

Mosselman Turbo makes lots of turbo kits for Mercedes cars. www.mosselmanturbo.com They mentioned on their site having a "bi-turbo" setup for 24v v-6 engines. Not sure if this if for your engine. Maybe something to look into.

Thanks Adam. I'll look into that.

The biggest benefit will be a faster spool time, since smaller turbos would be best; like a tweaked ct28, or a T-28. something that small will still boost up to 22psi of useful boost, and has a built-in wastegate...space and simplicity should be key in this case.
Someone listen to this guy. If you are TT and have your boost set to 1 bar. You are only going to run 1 bar.

HP "loss" through turning SC during acceleration is not much different than the "loss" created by exhaust backpressure during turbo spooling. And once you reach cruising speed, the SC realistically only requires about 1/3 HP to turn, since the boost isn't needed at that point. The efficiency of SC and TC (done right) is good enough that HP drain shouldn't be a problem.

I would go with a single turbo set up! Twin turbo is just to much R&D over the single turbo set up. I would run about 7-8psi MAX. Power gains would be great tough!
