Well, I finally got to the track for the first time with N20 in and I was really dissapointed! My fastest time today was a 15.1 on a 75 shot(ran 16.2 last year N/A). I was averaging from 15.1-15.5 all night. Shouldn't I be well into the 14's? I can't figure this out. My launch I was feathering the clutch from 3,000 rpms, I was hitting the n20 at the top of first hardly spinning, and power shifting the entire way. My compression is good, none of my jets were clogged, I had 16" rims on and my sub and spare in the back but I know those two things wouldn't take that much time off. So what could it be? My nitro jet is about 6 inches away from the TB pointing straight into the intake, should I angle the nozzle towards the TB? Also I was back firing alittle through out the night, is that a prob? Thanks for all the help, the numbers from my best run are below.
