I have a 2013 Corvette Grand Sport . I have UPP twin turbo kit ordered and was wondering how much boost i can safely run on a stock bottom end with methanol injection. I know there are a ton of different factors but there has got to be some type of base for a stock LS3 on 93 octane .

Depends on tune a a octane. I've been pushing my stock bottom end at 780rwhp for over a year and over 700rwhp for almost 3. Plenty LS3's out there making good power with the proper tune and octane.

i was planning on running 12psi , but have been debating on going up to 15 . I dont think that a great tune is going to be a problem . Guess ill have to see how she holds up at 12 and go from there .

I would do it. Keep the timing in check. I have a pump tune and race tune for when I need it. 93/100% meth and 104 Sunoco unleaded/100% meth

ls3 is a strong engine and the heads flow really well

spray lots of meth and watch carefully for detonation

should be a hoot. like the UPP kit, good value
