228r cam/heads Dyno Results Finally got car tuned and dynoed this past week at Redline Performance in Festus MO. Car is a 98 Trans Am, mods:
228r cam 112lsa
5.3 heads fully ported/polished (similar flow numbers as stage 2.5 prc heads)
Ported 78mm FAST intake
Ported/Polished stock TB
Ported MAF
LT headers, true duals with x-pipe
Bosch 36lb injectors
Ram Air cold air
3800 Revmax stall
3:73 gears
I was hoping for 400 rwhp. The guys at Redline did an awesome job and got me up to 416 rwhp with 395 tq. The bottom graph is a run with the stall unlocked, it flashed to 4200 rpms and put down 370 rwhp with 346 tq.

416whp with a stall and gears? I don't know that's a big number for that setup through a stalled auto but I'm sure the cold front pushing across the state may have helped.
