Sorry Rohn, I don't have any timeslips to post...
The quoted numbers are from the magazines radar based data acquisition system. The magazine article should be in the December issue of Motor Trend which should be available around the first of November.
I drove the car from Houston to/from Austin yesterday for a Viper dyno day. The car ran fine with the AC blowing cold air the whole way there and back. Coolant temperature stayed within a needle width above the 200 mark on the guage when stuck in the horrible Austin traffic with the AC blowing full blast cold air. On the road the coolant temp dropped to the mark under 200 on the guage. The weather conditions were typical mild summer weather in the low to mid 90's.
The car put down 589.0 rwhp and 596.9 rwtq on pump gas. It looks like the SRT-10 computers may pull timing with heat like the Gen II's did. They made two dyno runs and the second run lost a little power and torque. The car still was a little hot for the first dyno from the drive to Austin.
It was nice to see a confirmation to the previous dyno of 587 rwhp on a different dyno. The rwtq was above 500 from the beginning of the pull, 2700 rpm, until 6100 rpm.
