My first Dyno

[djbiever]

My numbers: 372.15 RWHP 375.22 RWTRQ 12 June 2007

I'm Happy. The Roush is Happy too. GITTYUP

Very impressive numbers!

Look at the temperater As well.... 91 degress prolly killed some ponys for ya.... i say u can could see 380 rwph easy on a cold 50 degree morning...


Edit - also henderson NV is 2500 feet above sea level!.... take that baby to a "at" sea level dyno shop, and do a nice cold run and i say u could make 390 RWPH maybe even push 400....

Ditto the heat in the dyno room sucked some life out of it for sure....

Congrats

Those numbers are STD corrected, so altitude, temp., or humidity are already taken into consideration.

If don't get corrected dynos, you are probably wasting your money, cause all these thing can indeed effect the results. Correction factors these thing in, so you know what gains you truly make from your mods. without having to guess about the outside factors that impact the results.

I had my GTO tuned there a few months ago and I too was suprised by the high numbers, 360/365. Then I noticed it was STD correction. They did do a great job and the car runs great! Great numbers for your Roush!!!!

The STD correction formula tends to run a little higher than SAE corrected numbers. The formula is just a little different. It is important to use the same correction formula and same dyno whenever testing mods. in order to get accurate readings.

STD, or Standard correction factor. The Standard correction factor corrects the dyno numbers to the international scientific standard conditions of 59° F, 29.92" Hg barometric pressure, and 0% humidity. Since cooler air and higher air pressure both result in more air molecules entering the engine, an engine will produce more power under STD conditions than under SAE conditions.


SAE (Society of Automotive Engineers) correction factor. The SAE correction factor tells you what the power output would be if the temperature were 77°F, the barometric pressure 29.23" Hg, and 0% humidity. As such, the SAE correction factor is conservative compared to the STD (Standard) correction factor, and probably more closely reflects the amount of power will be produced under real-world conditions. For this reason, SAE is currently the most widespread correction factor used by auto manufacturers in rating horsepower and torque output

Late to the party on this David. Nice numbers and about right in the sweet spot for the Roush supercharger

What do you mean Late to the party?

I was late to the party. I didn't see your post about this until just recently.

No biggy. That is just my first Dyno. I dont think there will be any more. I like my car the way it is now. My wife loves to drive it cause she does not have to shift as much to pass people. She is such a show off.
