Nice gains. I'm a little curious with your quick fall after your power peak though. Not sure if it's valve control issues (1.85 rockers and those fast lobes may not be a good match) or if it's just because of the reverse split nature of the cam. 451 rwhp is very stout for stock heads though. Good report.

I almost like the stock curve better since the power doesn't die off so abruptly. Hmm.

even though it falls off its still overpowering the stock motor so who cares. I had power fall off like that before with a small cam and when driving the car you could not even notice the power fall off it kept pulling so it just a line on the dyno.

Very nice. I read posts like this and then I wonder if its worth it doing an L92/L76 swap when you are already making 450rwhp with no head work on a cathedral LS2. A set of cnc'd heads would put you near 475-480rwhp I would think. Im confused on what I want to do. Maybe I should call Vengance.

Great numbers though.

Are you running a stock LS2 90mm tb?
Can you even hear that cam at all, damn its a sleeper. A slightly larger cam (for an A6) would also add an extra 7-10rwhp.

Very impressive. I wonder what your car would trap at? 450rwhp in a C6 should trap around 123-126 I would think. A little 100 shot would be nice.

I am wondering the same thing..

Anyone have a C6 with around the same HP... What would the trap speed be?
