I too would like to know how they got that engine up to 6,200 RPM... mine sounded like it was gonna explode at 5,950 RPM!

I also found a AWD (4 wheel drive) dyno and had a full pull done on my SRT6... good results, less than expected, but consistent and it only cost me $80.

By the way here's the thread with my REAL dyno results... the first was a misunderstanding by myself and the technician (Paul), the second was a good pull with real numbers. Disappointing to me, but more real and good pulls.

And a picture of the car on the dyno before being strapped down... just for fun...
