First time Dyno for my 99FRC. Went to the Dyno for the first time ever and took my 99FRC. The first run was the best run with 317.88HP, and 325.39Toque. Not bad for only having installed a Blackwing airfilter. I got 4 pulls and they went like this 317, 317, 314 and finally 314. So the engine needs to be a little cooler and the Air/Fuel was very heavy at 11.2 at WOT. Wanted to post some general numbers for everyone to see. And my best time at the track is a 12.58@110, with DR's.
Saturday I ran 11.973@112.98 w/1.621 60'

I hope mine dynos around that... I have SLP Loudmouth exhaust and Vararam VR-1b. I ran a 12.84@111.77 on stock wheels with just the intake... Now im trapping 114-115 but with some very low thread tires, lol.
Hoping for around 450-460 with 150shot...

The print states a correction factor "SAE 1.01" Temperature was 77 and humidity was 17% the barameter was 29.07. This part I am just starting to learn about...

Good numbers, manuals dyno higher than automatics due to less drivetrain loss. The correction factor is for the national average. A 1.00 would be spot on, no correction. So it corrected your actual up 1%, not much. If it was blazing hot and high humidity, it would correct up even more. If it was real cold, it would correct down for the average, which would be less than 1.00, like a .87 for example.
This is for several reasons, the most important being an average that you can compare to on any given day with any given temp, humidity and barometric pressure, and at any location. Otherwise previous dyno info from another day or location would be usless. So they correct for the variables that effect performance.
In simple terms, your motor output will vary from day to day dpending on the weather. So even though the actual dyno numbers may be less in the summer than in the winter, it will average it out.
The somewhat confusing thing is that it is an average of what your car will put down, but some days it will be less and others it will be more. I love the way my car runs in the winter!
Hope this helps.
