That's quick! What was your best 1/4 mile time? Are you on stock axles?

My best is 11.7 @ 129 with a 1.89 60'. The pass where I got the 1.7 60', my clutch stuck to the floor, that would've been a low 11 second pass at 130+. I'm upgrading to a McLeod RXT then I'll go back. Yes I'm stock axels for now.

I have the 20 inch NT05 DR's. I was at the track last night and at 2900 RPM's I was still spinning on the launch. I lowered the PSI to 19 and I am doing a good burn out before my pass. Is there anything else I can do to get these to hook better?

That's good to know that definitely answers my question on whether or not I'm going to stay with a stock clutch! I watched your video that was a nice launch and 11.7 is really quick especially considering you had clutch problems. What rpm were you leaving at?

Yeah the clutch has to go, especially since I'm on nitrous now

Thanks, I really wished I made a clean pass with that launch. Somewhere between 4000-4500

A new clutch should definitely get you in the low 11 second zone. I might go with a McLeod rst or good used one if I can find one. I just hope my axles/diff survive the year with an upgraded clutch
