Big problem the last few times at the track. I have been assuming this is my clutch but now I am having second thoughts...here it goes: I launch hard slipping the clutch from 5500. I hit bomb as 60' times 2.0X~2.1X, then the car totaly powers down from around 6000 all the way to 8000 were it suddenly grabs, engages, whatever and shoots to red line... I thought that the clutch was slipping but I dont hear the motor revving up durring the pause. The feeling is sort of like the motor retards timming by 100 Degrees for those 2000~2500 rpms after the launch, it revs up that slow (about 4 tenths or so)... This is a real problem and I cant get the good times till it is fixed... is it the clutch? Does any one else have anything like this? Please assist!!!
