L92 intake strength?
L92 intake strength? Is the stock L92/ L76 intake manifold strong enough for about 18psi of F.I.?
What is the "official" power band of this stock intake manifold?
What would the limitations be for a F.I. set-up?
Thanks for your help, fellas.

For forced induction. the best way to go is with a aluminum intake. Have you ever seen what a composit itake looks like after a FI or Nitrous back fire.
Also, technically speaking the L92 and L76 manifolds really two different pieces. While they fit the same heads the L92 is the Cadillac Escalade/GMC Denali intake for their L92 motor and the L76 is the is the Australian (G8?) car version of that manifold and nearly identical to the Corvette's LS3 manifold...as far as I know.
I have already in my possesion the 4-bbl, GMPP intake, but not too sure about it, as i have read a few threads on this forum about the aluminum intakes causing the intake temps to be greater than that of the composite intakes.
Yeah...I think im looking at about 7200 max rpm.

RedBeast or something like that was running an 81mm at 16psi on a 418 L92, stock l76 intake. He did something like 900rwhp without issues. The stock L76 piece will perform quite well in your application.

Hmmm...no worries about heat-sink issues?

Thanks again for your help, guys!
Horsepower difference between the 4-bbl intake and the stock/composite intake would probably be minimal, huh? Does anyone know the powerband of the GMPP 4-bbl intake vs. the L76 intake? Are there any dyno results of the two intakes available for comparison?
Thanks again for your help, guys!

I personally didn't say it would be minimal although I can't tell if you're asking or implying. On a boosted application with all things being equal the carb style will probably suffer due to the valve events. A cam designed around the carb intake will probably suffer a little in lower avg torque (2k-4k) but definitely makeup for it with peak power. The carb style intake will also have better fuel distribution at those huge power levels (although "better" is a pretty subjective term).
