I am going to Bowling Green on Saturday to the World's Fastest Street Car race and they have a dyno set up and was wondering. I thought about maybe getting it dynoed,will my 20's make the numbers a little lower or would they be the same as the stock wheels and tires.

 

Your 20's will lower your numbers. More rotating mass=less power.

 

Just dyno it with the 20's, that will tell you what your power in street trim is

 

I go to Bowling Green to race sometimes on saturday night fun racing, I have yet to see a newer model silverado there. When do you usually go up there?
