We dynoed and tuned up Red Devil last night at Stenod Performance. After some tweeking RD made 594 ft*lbs at 4200 torque and 569 HP at 6300 to the rear tire. Compared to Jackass last year 460 ft*lbs at 4400 RPM and 498 HP at 6400. All dyno pulls were done with the coolant temperature at 220 F to simulate track usage. JA was fast but I think RD will be a bit faster.
The new calibration has 11,000 changes from what we had at Gingerman. The car hauls ass now.
The graph below shows Jackass with dashed lines and Red Devil with solid.
