Well , after a few rain outs over here I finally ran the car last weekend . This was a test day with 200 other cars so only 3 runs on the day .
The 1st run was not good after hitting the shift button into 2nd gear 3/10th's of a second after the car left the line , the car filled with black smoke ( clutch dust ) I left with a .070 light , a 1.51 in the 60 ft , 6.03 @ 122 1/2 track and 9.37 @ 139 at the end . All data was normal so refueled for another pass .
The 2nd run I left the line with 2 hands on the wheel so I could not accidentally hit the shift buttons , reaction was a -.022 red light , 1.36 in the 60 ft , 5.55 @ 127 1/2 track and an 8.74 @ 149 at the end . I felt the car nose over at the 1000 ft mark and after checking all of the data I could not see a problem .
The 3rd run the reaction time was a .063 , 1.37 in the 60 ft , 5.9 @ 115 1/2 track and 9.42 @ 141 full track . I felt the car starting to misfire and got off the throttle and coasted with the early shut off .
I have pulled the plugs and found 3 out of 4 plugs melted . I suspected that this may have started during the 2nd run and went totally off during the 3rd run . According to the data I am all good on the EGT's , all good on the A/F ratio and suspect that maybe the timing map may need some attention . I am back in the US in 4 weeks time and will bring some data with me to try to find some answers . I need to know how much timing I need to have as I am at almost 32 lb's of boost and have 22 deg. advance . The intake temps are around 45-48 deg. and I still have more boost pressure that exhaust pressure , ROD.
