I was thinking after my last reply if it were the pump you wouldn't be running more mph. Did you go to a different slick than you were using last year? I agree that it is not the alternator. The biggest difference I see is the change in slicks. How many runs do you have on them now? We had a new set we put on our dragster that took about 40 runs to settle in!! I will be breaking them in on my roadster from now on. I can do a better burnout on the for a couple of passes. Are your 60' times varying or everywhere on the track?
