Another 1,150+rwhp street car by Speed Inc. We recently completed a twin turbo build on a very clean 00 Firehawk for forum member Classic.
Engine is a 427ci LSX built by HKE with ETP LS7 heads and hyd roller cam.
GMPP single plane intake that I modified for staged injection.
Turbo system is truck manifolds, twin Precision 67mm turbos, air/air intercooler, dual 3in exhaust to the bumper, tial 44mm wastegates and tial BOV.
Drivetrain consists of McLeod twin disc clutch, G-Force T56, Dennys MMC 3.5in driveshaft, 9in rearend with 3.25 gear.
Engine management is BS3 with staged injection and dual fuel systems. (Primarily runs on 93 octane and automatically switches to 93/116 mix when first set of injectors reach 80% duty cycle).
We are extremely pleased with the results

thanks guys!
this car is sick!
The car is stock appearing both exterior and interior wise ( no cage yet ). The exhaust is about as loud as a stock dual/dual with cats IMO.
+ 23 psi is just the start and with an LSx. We all know there is more power here if the customer ever feels like turning it up
The car will be heading back to NC in a couple weeks to enjoy nicer weather.
