Where will it spool at?
Alright need to know where about a T88 would spool on a stock cammed stock displacement LT1. Me and a buddy of mine where having a debate about it....full boost would be 7-9lbs on stock motor. Let me know what you guys think.

If 7 -9 psi is all you are going to run a T88 is way too big... get something a lot smaller and it will spool up a lot quicker. If you are going to run 25psi in the future maybe go ahead and get it and upgrade the engine later.

I plan on going big in the future just not now...I could go with a t76 like alot of guys run for now and when engine gets built step it up to the t88.

The 88 is not worth the extra headaches. A good 76 will support 1150 - 1200, while an 88 will only go to 1250 hp. This is because the small T4 exhaust side is reaching its limit. Jose had a 76 on a 355 making 987 rwhp and switched to an 88 and gained less than 20 rwhp along with later spool and less peak torque. Step up to a T6 and only a 91 mm and you get 1550 hp.

I had been looking at the GT-42 76T a little bit but just didnt much care for the A/R advertised on it...im sure they have more options on it. Could you guys give me a few sites where a coule place to pick up a T76 would be?

Most we have gotten is a spike to 23-24psi. Will only sustain around 20-21 though.
