Here is the pull from this weekend at LSX Performance Dyno Tuning here in Victoria, TX. She put down a nice 471 rwhp & 436 rwtq. I'm very impressed that it did that well with the stock air box, ls7 intake, and stock axle back.

That actually is crate form. I bought the engine straight from gmpp and had it installed. The only add on is a slightly ported ls7 intake and of course the ar headers and exhaust.

So does the title of the thread still hold true now that you know a bit more about what's required to get the most powerful G8 (at least 730whp on 93 octane, but I'm sure someone's gone higher in the US, WAY higher in AU), or have you down graded to trying to achieve the most powerful NA G8, or have you downgraded even further to just getting it over 500whp and being happy with that?

I'm focusing on the drive train at the moment and making sure everything can handle the power before I throw a big number at it. I still have every intention of going for the highest horsepower G8 whether it be NA or FI I'm unsure, still trying to research and see which route I would like to take. I'm enjoying the amount of power it has for now though. Easily beating modded C5 and C6 corvette's is pretty nice.
