Hey gents, it’s nice to hear terms like area under the curve etc. I see it every day with customers only worried about the peak hp #s and don't understand the dynamics of tractive effort and the motivating force behind what drives our cars to feel the way they do.
Kevin..very impressive results you should be commended. Coming from someone who does calibration ( on a GM scale) I think people don't appreciate the effort that goes into these things (except KPG). Very nice.
Dock
the weight comes from a spec provided by the EPA and it encompasses the vehicle equivalent weight (loaded with typical air pressure etc.), rolling resistance and "weight" of average passenger as well as cd equivalence.Thank God that is calculated for us lol I would hate to do that for every car. The dyno is an eddy current design and will actually increase resistance as speed goes up just like the conditions on the street.
Hey KPG thanks for making my Monday worthwhile...and to all, I have not run my stage 4 on the dyno yet.. I guess I have been to swamped lately (and slightly lazy)and I guess now I will have to do it to provide the data we are all wondering about
ps a camera next time is a great idea had I thought about it a would have grabbed the company one ...Damn!!!

Kevin,
The new program sounds interesting...What is the boost level of the new 1/4 mile program going to be? Any idea how much you & Kevin expect it to help in terms of 10th's and MPH in a typical run?
