826 RWHP from the 346 cube APS twin turbo Hi Guys, Our tech team has been playing with a larger comp wheel on the F body twin turbo system, see graph below, enjoy!
We estimate this to be around 900 rwhp on a dyno jet inertia dyno.

Gets me excited about my new combo. My new low compression forged motor is almost a carbon copy of yours except my cam is a little bigger and my FAST 90 is ported by Tony Mamo.
Are you running the 60 lb Siemens injectors or are you running bigger? The new Racetronix 79 lb high impedence injectors look pretty awesome too. I'm digging your dual pump fuel system. Any flow loss at this power level?
