Dyno results
Hello guys and gals. I need some help as I am not an expert in this field I bought an 09 Challenger SRT8 with only 15,000 miles I added a 2.9 Whipple supercharger Kooks long tube headers minus catalytic converter with black widow exhaust to get to the diner in August it was around 89 degrees and humid my result was a disappointing 500 horsepower. How much do you think the temperature and humidity affected my results as I was fully expecting at least 550 horsepower I'm going to take it again soon as the temperature is much cooler what should I expect. Thanks
