Shorty header vs Longtube header Dyno #'s
Well it's not the greatest comparison but I'll see bigger gains once I can lean the car out to where is was when I dynoed the car with the shorties.
Jeff- Wasn't you that overlapped that one guys dyno# on corral can u do that with these please? Thanks. It's gettin there. The only thing I changed was the headers. -Mark

Take into consideration that both tests were done on 2 different dynos. The differences between the 2 could be quite large depending on the condition of both dynos, the heat in the dynos bearings, and the way that the parasitics were set up. Unfortunately its gonna be hard to get a true comparison between the 2. I would say that your best bet for comparison would be at the track.

Mark I could but since Fordspeed decided to scale the torque differently then the HP it would skew the results when I layed them on one another. I don't know why some shops do that, it's stupid in my opinion but what do I know. I should of noticed before I even opened photoshop that your HP and torque didn't cross at 5250.

Jeff, the computer sets the scale, not us. After you make the run, the computer pretty much takes over. If your torque and horsepower didn't cross at 5250, it wasn't anything that we did, that's just what the computer read.

torque (lb-ft) = 5252 x hp / rpm
hp = rpm x torque (lb-ft) / 5252
I can double check with John from Secret Servies but i'm 99% sure I'm right on this.
