Well I finally got down the track.
We were able to make three runs, the first one I had some tire shake and it broke the trans brake wire in two different places. I was unable to back up as I have a pro brake and to back up you have to put it in reverse and hold the trans-brake button. So after the burn out I just ran it down the track (no time slip).
The second run we tried to get rid of some of the engine proposing (rev up idle down) by leaning out the idle circuit. We went from the 70 pill to a 75 and dialed the idle circuit back by three notches. This did smooth out the idle, but the engine seemed to labor and after the burn out did not want to stay running. Ran a 8.290 at 155.95 three tenths faster than our best run and one MPH slower. Hottest EGT was 1095, the number two cylinder read 450, for some reason that cylinder has always been cold. 60 foot was 1.197. Air density was 1798
The third run we fattened it back up let it porpoise, it launched hard and straight and seem to run much better. Ran a 8.258 at 157 MPH. Other than the porpoise idle it idled fine, no problems with it running after the burnout. 60 foot was slower at 1.240. Air density was 1633
All testing was done with 43 bottom pulley and a 56 top (-23.2 under driven verses the 43 bottom 54 top we had talked about (did this because of your feeling that we would be to fast with the 43 / 54 combination))
Launch was at 4271 RPM the EGT on number two is crazy starts at 678 and at the end of the run is 280 and is not smooth at all (I’m thinking the sensor is bad)
Max boost at the top end was 10.32
So now we have to slow it down by .250 to run our 8.500 index.
Both the engine and the transmission ran MUCH cooler than without the blower.
All in all a good day
