how much boost can the L76/LS3 intake handle?

Planning an AES 398 LS3 based engine with LSA heads. Will be maxxing out my D1sc (3.4 pulley, aster bracket) for 750-800 rwhp. Will the L76 / LS3 intake hold up to this (probably 15-18 psi) or do I need to switch to the single plane vic junior/elbow?

I treied searching and found two unanswered posts about the same thing. It seems like the votech and procharger kits are run by new camaro owners making 8psi, so they must be good for that. But can they hold 15psi? Does anyone have experience with this?

I've seen the LS6 and the LS7 go +20psi for years without problems. I would try it before buying something else if you already have it. Just make sure the tune is good as a backfire will blow the rear panel out.
