I was awaiting the dyno graph, but don't see it yet. What you don't understand is that maybe the original poster did rev it past 6400rpm and he is listing his peak numbers.
BTW, on my 383rwhp run with my XE230/236 (that made peak power at 6000rpm), I was only at 340rwhp by 5100rpm. I dont doubt that he should see 400rwhp if he can get a clean pull up to 6500rpm.
W/out a graph that's impossible to know.

Looks like they were only taking it to 5500?! Where did you get this car dyno'd? Go somewhere else. This graph just makes no sense.

I'm still a winner in my book
That was my point, the lack of rpm. Didn't say he doesn't have a problem. Don't worry RealQuick, your prize is in the mail.

Well, 24's arent enough IMO. You need to see how the AFR was on the run? Did it go lean at all.

I agree 100% dude. I understand alot, your not teaching me anything new here I responded because people were saying his power should be higher than 330rwhp... well yeah... I was pointing out that the peak #'s were only at 5100rpm.

If the pull went past that then obviously he needs to figure that out since that cam wont make power at 5100rpm anyway.

My apologies, sir. I was thrown off by this statement which seems to be pretty cut and dry:

It won't happen again...

are you serious, even after proof he reved it past 5100 , you cant be serious- the power obviously dropped off, rpm's have nothing to do with his problem

i would be more worried about where your a/f was and your injector duty cycle

Relax. He is joking around.

It looks like he let off at 5100rpm and stepped off the gas pedal.

I have a bud that dynoed his car and he kept getting out of it really early.

The dyno operator asked him what he was doing and he said he was at 7000 rpm....he was at 5000 rpm and his factory tach was WAY off.

Easy buddy, no need to get your pantys in a bunch. Like RealQuick said, just joking around.On another note, I have no idea if the operator tried to take it past 5100 or not. My quess is no. I have seen some weird stuff on dyno graphs after letting off the gas, and have no idea what that graph is trying to say. I will add this though, if the guy didn't take it past that point, you would hope he would have some insight on what might be wrong.

The dyno operator said he did not want to take it up higher because it had allready peaked in hp at 5100. I know it pulls hard @6700-6800. Im going to try another dyno because this place has pissed me off.
