TypeGSR196

I have a GSR w/ JE pistons 9:8:1, eagle rods, arp headstuds, cometic, thermal exhaust, ctr intake cam, skunk2 manifold & cam gears, port matched the intake side of manifold, the head was shaved 3cm to be safe w/ boost........
Precision 880 injectors, fpr, venom fuel rail, walboro 255........
Garrett t3/t4 .70 a/r 57 trim .63 a/r, a obx manifold, greddy bov & running AEM.....

ok guys, I would really appreciate any info........i'm tuning soon so i'm just anxious to know..........

thanx in advance.......

how much boost are you planning to run?? That sounds like a solid set up though...

TypeGSR196

i have a 7psi spring so i can use that for low boost, i 'm thinking more like 20psi for high boost...........i'm working on getting my dual mbc..........

Schister66

nice....i think on 7psi you could expect somewhere in the 250-260 range and at 20psi i think somewhere in the 370-390whp range, but its early in the morning and i'll probably edit this later.....

ok, Thanx alot bro.......

TypeGSR196

anybody else's opinion............

i have a similar setup with a smaller turbo... tuned on crome...with those comp pistons you should be around 320whp @ 10psi reving to 9k... and 20-21 psi you should easily break 400whp... i tuned mine on 21psi and made 460whp...with ctr cams and stock sleeves...
