Ok guys wanted to share the news lol I'm dropping off my cammed 2011 2wd Denali off to the speed shop and getting a custom fab front mount T76 with the intercooler behind the grill and a duranax 4" exhaust any idea what I would be making with 8lbs? Right now I'm at 422rwhp 417rwtq oh and how much psi can my bottom end take? Oh and it's a 6.2L

Should put you into the 500+ range real easy. Personally I like to call it quits at 600 to the wheels unless I'm going to pull it apart and widen out the top ring gaps, and do other helper things like rod bolts and what not.

Hope you like it! Sounds like it will be a badass!

Hmmm good to know, thanks for the input! So I'm guessing 620 to 650 to the wheels would be pushing huh ?

Yeah, especially for a hot day in Dallas, that's gonna be pretty brutal. I'd call 600 the limit.

Sorry if that's not what you wanna hear, but I stuck a ring land before and broke a piston all to crap. And I don't think you wanna have to go through those pains. :/

On 8psi through a 6.2 I would expect 550 on a reasonably safe tune. If you get aggressive, I think 600+ is definitely possible depending on the setup.

its understandable but i think 550 to 600rwhp should still put a big smile on my face lol thanks again ! @ GRAY GHOST SILVERADO by the way nice setup you got their

whoa whoa,back the train up for just a second.Would you give us a break down on how you got to 422 HP cammed?What other supporting mods? cam specs? tuner?you hit the track?Appreciate the info.

Aren't the 6.2's rated at 403 HP at the crank? So camping it and getting 422 rwhp doesn't take much imo. Thus why I wish I woulda got a 6.2 instead of the 6.0..
