Heat and humidity has a big effect on numbers too. Did you let your car cool down an hour or more before you ran on the dyno?
Yes, it was cooled down between runs. I had my I/C pump running at all times, I could see the HE temp gauge and it was down in the 80's and it was about 80 degrees down there. I was really disappointed, I expected at the very least of 310 rwhp. I wonder what type of dyno these guy's were on.
2403SRT = 340
Moparrbust = 311 @ 4,800 RPM
srt6_crossfire = 355
Chi-townSRT/6 = 296
NeedsWings = 330 (5 months ago)
waldig = 322 @ 5,500?
