I got a chance to pull a couple on a dyno that my friend's friend owns. Now I have a Roadmaster so if you think it looks funny that's why. To me the graph doesn't look right.. The Runs were done on a mustang dyno..
So do they look weird to any dyno pros???
Here's a list of my few mods
1.6 Comp Cams Pro Mag rockers, CM 614 springs, LT4KM, 3.73s/Eaton, Raiss Intake, Modified Herter Tune, 160* T-Stat, TB bypass,David K 52mm TB, 2800 edge TC and a teamtripp tranny, F-Body MAF and EGR, All around SS suspension, , Try-ys w/ dumps, pypes, prostreets, MSD coil,
My one friend commented that the graph didn't look right. I believe I was making 70mph to 120mph pulls but I can't remember if I ever hit 120 or not before I shut down.
Temps were around 65 outside w/ a 72 % hum and a 30.12 Pressure reading.
Since I'm asking, is there a conversion calculator to convert those figures to SAE NET and or Dynojet #s?

My curve looked something like that. At 5000 rpms it would instantly do a 50 hp drop, then go back up like 500 rpms later to peak horsepower. I thought it was my opti maybe, but it was definetly spark related. I put in a MSD 6A ignition box and it smoothed out the curve perfect
