I did a little reading over at www.Supraforums.com and it sounded like the C5 was detuned but I am sure it was not detuned for the dyno... can we get more accurate info?

Needless to say I would expect that C5 at 1100-1200 rwhp to run 160mph trap speeds. Isn't that John Meany territory?

I still haven't talked to the guys yet (they are most likely still sleeping off the 16hour trip back, but the Vette was indeed detuned to about 775RWHP for the drags. The owner was tied up driving his Supra all day because of the early morning rains and the 'hot lapping' of the event to get things done on time. He wasn't familiar with the car at all and was taking it pretty easy as far as I'm aware (97MPH in the 1/8 mile). He did manage 137+MPH in the 1/4 from what I've been told even with the lackluster 97 in the 1/8...

The car had only been running a week prior to the event and really hadn't seen anything but dyno time since we were all busy working on the 3 cars that ended up going to TX... I will get the timeslips and the dyno chart up ASAP (even the 1200RWHP that we did here in Tucson before we loaded it up for TX).

It wasn't detuned for the dyno, but apparantly, the old dyno had a speed limit of 160MPH and this caused the first two runs to abort with no data. On the third run the operator shut it down before 160 so at least some data could be recorded. I haven't seen the chart, but I believe it was 1013RWHP@4800RPM... It peaks around 6300 and at 4800 the rate of change on the graph is still high...

You would think so. 1100hp is deep DEEP 9s, if not 8s.
