Highest HP out of a ZR1 to date!!

So basically it comes down to airflow restriction, the intake components before the blower cannot keep up with the air demand that the blower needs at higher RPM's. Makes sense.

The idea is very simple, run the SC at lower rpm to give instant torque and boost. then once the turbos start to spool and put a positive presure before the SC, you open a valve that will bypass the SC direct the air into the intake (or the chaergecooler in the ZR1 case).
This way the SC is not restricting the turbos at higher rpm yet you still get instant boost with little to no lag.
'what about the power the SC will take?' well the SC wont actually be doing anything, just spinning away nice and freely as the presure will be the same on both sides of the blower.
Now that would be a KILLER setup! just have to find somewhere to stick 2 76++mm turbos!

The way to do a twin turbo and supercharger setup, and the ZR1 is one of the few V8s that let you do this, is to bypass the SC once the turbos are spooled up.
The idea is very simple, run the SC at lower rpm to give instant torque and boost. then once the turbos start to spool and put a positive presure before the SC, you open a valve that will bypass the SC direct the air into the intake (or the chaergecooler in the ZR1 case).
This way the SC is not restricting the turbos at higher rpm yet you still get instant boost with little to no lag.
'what about the power the SC will take?' well the SC wont actually be doing anything, just spinning away nice and freely as the presure will be the same on both sides of the blower.
Now that would be a KILLER setup! just have to find somewhere to stick 2 76++mm turbos!

so...the LS9 is a forged 377 with a 9.1:1 CR...I wonder how much GM will sell it for minus the blower, the heads should be able to use a LSX intake. Just when I tought the LS7 was the perfect GM small block...

Totally true mate. you would have to run a seperate bypass valve, perf. one about the same size as the throttle body.
