With a p1 TR CHETR cam fast 78 Ported stock heads 9# I made 610RWHP 570RWTQ at 5800RPM after spark started blowing out. That was threw a RPM A4 and VIG stall

 

'03Z, 1-7/8" ARH, P1 and Alky Control

 

My brother is the original owner of his '95 Formula. It has had a ProCharger P-1SC on it since sometime around '02-'03. It still has the stock cam, stock heads, engine hasn't been apart. He has run a best time to date of 10.914 @ 121.90 mph with a 1.452 sixty foot. It has a Moser 12 bolt with 4.30 gears, and he uses M/T ET Streets that are 28" tall. Bob

 

nice, i wonder what number you will put up if you spin motor up to 6800 rpms.

 

stock ls1 bottom end and cam (6-speed)
p1sc w/ dual 3.5" I/C
LS6 intake
42# injectors
Racetronix pump
trick flow 215's
ati stock 6 rib 6" crank pulley/3.5" blower pulley
lth's and 2.5" duals out the back
7# of boost
486 rwhp
456 rwtq

 

hmm...I would think with you having TFS 215s & a full exhaust that you would see more than 486/456. I hope to get 450-460 with 7-8psi with completly stock motor, but with a after market Y pipe & a SLP catback & Meth.

 

With 8 psi of boost you can generally expect to see a 140 rwhp increase. With higher flowing heads, etc this number can go up. If you add 8 psi of boost to a stock LS3 engine that has headers and exhaust, you'll pick up more than 140 rwhp. Unlocked automatics with a higher stall may not show all this additional horsepower on a dyno, but the 1/4 time slips sure will. Bob
