We knocked off a clean pass at Etown on this last sunday, Nov 20th. We changed to a larger intercooler core, changed the rear suspension to the D2's (from KYB AGX & soft GC coil over sleeves), and set the alignment to zero at the car's maximum launch attitude. Boost was set back to 40psi and the plug gap was put to .014. Now the air temps are more reasonable at just over 100*F at the traps, which accounted for about 2mph gain at the same boost level compared to the 144mph run that had max AIT of 156*F. The rear suspension was worth some stability on the launch too, as it now leaves straight and doesn't crush the back end down. With the AGX/GC suspension it would slam the rear end down, cause the camber to go way negative, and seemed to bounce back up and upset the car. Now it just hooks and goes straight with no drama!
Unfortunately, we broke something in the trans (stock automatic), I think likely the front diff or the center transfer gear on the next pass. After the 9.3 we hung around a while expecting the tech guy to come throw us out, thankfully he didn't show. So we did the pre-run retune and got it ready to try and improve on the 9.36. I added a few psi of boost, one degree of timing, and turned the shifts up 200rpm. Nelson launched it at 12psi on the 9.3 and got a 1.37, so we decided to shoot for a 14-15psi release and hope for a 5.xxx 1/8mile and maybe a 9.20@148mph. Unfortunately, it broke right off the line.
So next year our plans are to put in all the required safety equipment to legally run in the 9's and 150+mph. (cage, chute, window net). both of us are going to get an NHRA license as well as updated helmet and fire suits. Plan to remove about 200-250lb from the car while still keeping it street-looking (much of the weight being light brakes, light wheels, removing the ABS, radio, AC parts...stuff like that). I really believe this car can run in the 8.9's @ 150+ if we can get it to hold together on a 1.2 second 60' time. /ubbthreads/images/graemlins/rofl.gif
Figured I would start a new thread for the video rather than tacking it onto the end of the last thread where people might miss it.
