Ok. Where to start?!! First the good stuff...... the car went fast without any vibration. Absolutely as smooth and vibration free as possible. Considering the DSS differential conversion that includes a new drive shift and the huge Radial Pro tires... that was a big relief! So. I can check that box and move on. Due to the increase in torque and less then desirable gearing with the new rear end, we knew that it was going to be difficult to put it to the ground on that old un-prepped runway. It was. Procedure went like...... drive it slow until second, start picking up speed until it shifts to third. Give it a little more until it shifts to forth and put the peddle down. When it starts spinning..... short shift to 5th and wot. At that point it’s moving hard and when 6th is wound out to 7000..... nothing. The shift light is on and not going off because it ain’t shifting. Apparently the pcm doesn’t think you should shift into overdrive with 1000 lbs of torque. Pussy! So when I realized what wasn’t happening, I shut it off a second before the finish line and went thru off throttle at 173 mph. Tried again just make sure that wasn’t a fluke and with similar results shut it down earlier for a miserably slow 160 mph. Now it was in the afternoon and we decided to give it one last try shifting manually and log some data. I was out of ice so it was going to be a hot one. The outside air temp was 100 degrees and the DA was 3300’. So, same procedure but using the paddles and got it into 7th for a fast time of the day. 176 mph. Now for the one problem...... oil leak. Come to find out what is going on with that here on the forum today. Huge thanks to ZHC for sharing his experience with this. Apparently Thitek heads and FI Thermal Spacers are not as compatible as I thought and have issues. We understand what that problem is now and hope to have it fixed and be running for next weekend.
