Ok that makes perfect sense then. I am not too savvy on the twin turbo setups although I should research them better for personal gain. Please correct me if im wrong but isnt a sequential setup basically like what the Supra or FD3S RX7 has, and a bi or just plain twin turbo like what you would see on a 350Z?
Yeah man! Check out my twincharging thread. There should be some good theory there. If not, I can post whatever info you want!
Yes the Supra, 3000GT VR4 and the FD RX7 are the only production cars I know that came with factory sequential turbos. There are two variants. One utilizes two turbos of the same size, and under low throttle/rpm all of the exhaust gas goes through one turbo to keep it spooling quicker and in its efficiency range, at higher rpms/load exhaust gasses are allowed through both turbines and both turbos are creating boost, which if you can read a compressor map, basically just take the CFM or LB/MIN and double the numbers.
The other version uses one large and one small turbo. Same basic function at low rpms and load, but instead of bringing another turbo online, the exhaust gasses switch to the large turbo and the small turbo is bypassed.
Biturbo from the very little I read is a compound turbo system.
