I get what Roccodart440 is saying. There are cars that can make all kinds of rwhp, but either can't put it down because of tuning issues, or bad driving. And also, there are people who are either full of poo, or actually believe they are making a certain amount of power... I personally don't care about dyno numbers. I view a dyno as a tool. If you want to know what kind of power you're making, take the car to the track, weigh it and do the math. ;)
