how much horse power is my car going to make i have a 383 lt1 with 210 afr competion heads. 8.1 compression custom tpis boost cam, 58mm throttle body 120lb injector. 24x coversion with a aem driver box. twin 72mm turbos. water to air intercooler, going threw a built th400 trans with 3500 stall. 3.25 gears in a 9" rear. and 28-13.5-15 tires
on na with 11.1 compression and 42lb injectors it made 580 on the crank at 7200 rpm and now i lowered the compression and put turbos on. and i was wondering how much i lost going to 8.1 compreesion from 11.1. and how much i will make off boost. it put down 550 at 3 psi on the wheels when it was tuned and we blew the header gasket out. now i have locking header bolts.
so

Assuming somewhere between 1-30 pounds of boost should make precisely 763 RWHP 811 RWTQ going by my calculations

Why in the hell did you go so low on compression?
It sounds like you just picked that number out of your *** instead of defining a fuel and boost number to stay with in the octane limits of the fuel, then choosing a compression number.
Unless you plan to run 30lbs on 93 pump gas... lol
