For one, that graph is HUGE!! Two, how do you know that the peak of the cam is at 5,000 rpm? I would think you would have wanted to pull it to ~5,700 rpm to make sure.

 

Is that graph corrected for the conditions? Usually the correction factor is indicated on the graph somewhere, but i dont see that anywhere. Call the place that did the dyno and ask them to email you a SAE-corrected version of the graph. It will make it a little easier to compare your numbers with other people.

 

Because as far as I know it has the stock cam in it, I don't hear or otherwise notice any difference, so the guy went with the factory redline. Yes it is corrected, the guy showed me the std vs sae difference on the computer. It doesn't say it on the graph but did on the comp in a pull down tab to select the diff chart to see. So I'm pretty sure this is the SAE corrected version cuz thats the last one we looked at before he printed.
How much do you think the header leak, a pretty bad one (it annoys the hell out of me anyway), affected it?
Someone said headers can net you around 20 hp over stock, thats a good bit, so if I have a leak where the headers meet the y pipe, I'm wondering what kind of difference you think that could make?

 

Factory redline is 5,500 rpm, I believe.

 

I am pretty sure factory redline is 5700.

 

Yep, that's right. I can't look at my tach right now, and I've long forgotten about the factory redline.

 

HP is on the high end but reasonable and a good number.

I think the TQ is an error. Not bashing, just my .02 cents
based on reading hundreds of dyno posts.
