Default yellow springs with boost
Do people run the yellow springs with boost?

I'm looking to run about 10psi on my stock long block ls2.

Anybody?

I used them on my old 2500hd crew 4wd with bone stock 6.0 and 70mm front mount, up to 12psi with no issues. Of course I never took that motor over 5800 and 12 psi was a rare occurance.

stock 191k mile ls1 springs taking 9lbs @ 6000rpm on a daily driver. Been that way for 20k. Id use em. Running it on a dyno should show where and if valve float occurs.

I'd put some good springs on it being as the ls2 has the better cam, springs are cheap insurance!

I've got the yellows on my T76 5.3 build...havn't had it tuned yet but I've heard good things about the LS6 springs with boost. One of the chevy car mags just did a 76mm 5.3 build with the LS6 springs and made 594 HP at 12 PSI with no problems.
