I see the A4 and stall effecting the #'s, and the mail order tune being more of a hold back than the heads or Hot Cam........

I would say 335-355 RWHP depending on how close the tune is.
340-350 RWTQ

This is not a knock on mail order tuning, there are just WAY too many variables to get the tune right the first time. If it is scanned and you get some updates, the #'s will definitely be better since the tuner will have more to work with.

Ok guys, here's the deal. I get there and it's a "Superflow" dyno(wtf is that). They wanted me to start at 40mph and end at 90. I told them I wouldn't be in third gear, and they said it would be ok, so I tried it. First time only pulled like 302rwhp in second Second time, I nailed it at 40mph, flashed the converter in the process and lit the tires up on the dyno The chart spiked 532rwtq!! After that I told them that I was going from 80mph to whenver I ran third out. So I did that for two pulls. First of them I got 327.9, the second time around it pulled 333.3rwhp.

I think their dyno is off(it's a dyno at a local automotive school) because they had a guy with a 67 camaro that runs high 7's in the 1/8th only pull 320rwhp! I'm not going to complain though, it was free, and it was really cool that I got to use their dyno and see what it's all about.

That's cool and all, but in reality dyno's don't mean much. I know a guy here in town that ran an 11.7 w/ 340 rwhp in his firebird. Stalled A4 LS1. So w/ your stall you have done good, potential to be pretty fast w/ 333 rwhp thru a stalled A4 is high. Good job man. So don't be bummed about the numbers (even though I know you don't seem to be).

You got the graph? How much torque?

What RPm was the 330 rwhp at?

It's all good. If I want some real numbers I can brag about I'll go over to this place in town called performance garage. They have a dynojet and come highly recommended. It'll probably be a while before I get curious enough to shell out $75+tax for it though.

With a hot cam and stalled A4 you won't get huge numbers on a dyno. But you'll get more consistent track times that's for sure.

333 is believable. Not totally out of range.

I dont' have any RPM figures. The part of the dyno that you attach to the #1 plug wire was broken. It showed HP only but not torque.

That's very strange since HP is calculated from torque and RPM. Weird.

Even if 333rwhp is correct, it's still a very nice amount of power.

I'm jealous.
