2002 5.7 ls1
stock heads and compression (10:1)
radix 112 magnacharger (innercooled)
2.9 pulley
60# injectors
1 3/4" LT headers
LPE GT2-3 cam (207/220, 118.5LSA)
Tune
its also a 6 speed car

im considering a 90mm jtube, but dont know if its worth the extra $$$ anyone know how much they are and where you can get one?
what kind of power gains off of these?

also i guess this kit makes 6psi on a stock truck engine but on an ls1 only makes 4.5. the 2.9 pulley should make 6-7 psi on an ls1.

i was also wondering if anyone had any suggestions on making this setup more efficient.

im currently running a 9" with 4.11's also, ive been thinking about swapping to an auto/stall/3.73's but thats more $$$$$

i have an ls7 clutch right now.

oh the car is an 88 gta that is about 3200lbs

if speartech sees this, i was wondering if you were running a 90mm tb.
