About a month ago I picked up a Frankenstein of a project, any opinions/suggestions are welcomed (good/bad).
1999 C5 FRC setup for daily driving/reliability, made 560whp on 12lbs and 460whp on 6lbs on 91 octane. Runs rich, AFR 14 in idle and 10 or less at WOT based on gauge:
LS6 swapped (forged/balanced) Turbocharged (Turbonetics single T76) Front mount intercooler Tial waste gate and BOV Meth injection( not hooked up) Boost controller(in center console) Dynojet wideband commander S.D. tuned 60lb fuel injectors Walbro 450 fuel pump Compstar rods Mahle pistons ARP bolts Comp 918 valve springs Comp Gardened push rods 317 heads Z06 cam
Although I still haven't driven the car since its dead of winter, and in storage until Spring......... Before it went in however, I had new brakes all around (rotors & pads), new Bilstein shocks all around, Centerforce DYAD twin disc clutch, MGW shifter and lower box, BTR .660 springs & Ti retainers, new torque tube bearings and couplers and the A&A Si trim supercharger kit with 4" pulley installed and tuned on my mild h/c 2003 base 6spd couple with 317 heads and 226/228 cam. 91 octane and tuned to be safe and I'm happy and can't wait until spring to feel the new power. Dyno attached
UPDATE: After getting the car in the spring the tune was terrible and fuel pressure unstable so I had J&S Performance here in Colorado install A&A single pump fuel system, a 3.8” pulley and now it’s a BEAST — 701whp/574tq
