2004 gto ls1

9psi on stock springs??? honest opinions and hard facts welcome. Im going to either go with the stock tail spring of 7.xx psi or go with the 8.70 spring. Id obvisoulsy like the 8.7 spring.

im being told by another gto (ls2) that i should be fine. He seems to think i could do the 10lb spring and be fine?? thoughts please

I was told to not go above 8psi on stock springs. I have no facts to back this up, just reputable vendors and people that have told me this. But this is on a 00 t/a, Im not sure if the springs are different on a gto or not...

def. but im nearing the end of my budget and just really want 9-10psi until its time for the real build. This is all temporary. The real motor build is happening throughout this year. but if i can have 2-3 more lbs of boost for 50 bucks. why not. lol

when the 408 build begins this season, trust me, i will spare no expense. this is just a hold me over type situation.

The Patriots are only like $200... I'd just get those now and reuse them later on. No sense in spending $50-100 only to realize that they're still floating the valves... Plus they're kinda a bitch to change on the car... do it once.

Some LS1s will float even without boost, will just be luck of the draw if you get away with it or not.

If your gonna spend $$ on springs just go with Patriots and be done -then reuse on your next build.
