Also, you should run a full 1/4 mile to see what your trap speed ends up being. It is helpful in diagnosing other issues.

 

hey thanks for the input i thought it notwritenew at racing on the track so you are saying the speed should be more or less we only have 1/8 around here

 

Your trap speed in the 1/8thand your 60' seems very odd. My trap speed varies from 85 to 88 mph in the 1/8th with times running from 8.01 to 8.79. Not to mention you are running a larger shot.If you do not have a warmer, by the ZEX warmer. My warmer is completely mounted in the trunk with the switch and everything soI didn't have to drill another hole in my interior somewhere. The warmer will give you consistant pressure with 1 lbsor 10 lbs in the bottle. It's only$110 or so shipped if you shop around.

To give you an example of bottle pressure importance, on the dyno, my car only made 40 more rwhp with a 75 shot (yuck). This was -2 timing +4% rich at WOT on a COLD 1/2 empty bottle. When hitting it on the street with this combo you can feel the difference between the previous set up and a warmer bottle, 0% rich at WOT . It equals a large gain and more HP. The tuner said I should expect closer to 65 RWHP with a 75 shot which seems about right, not a 40 rwhp gain.

The difference in the 3 runs are as follows:

1st run I could feel the nitrous surge just little. I can purge my N2O line but not my fuel line to get it cleared out and run pure cooler fuel. Plus there was a timing light issue and I sat at the line long enough that my tires cooled down. Plus my bottle was cold asI forgot to turn on the warmer.
2nd Better60' with OK shifting
3rd My best 60', shifting and 30 min cool down which I think made the biggest difference.

 

thanks again for info i have been looking for rims so i an buy tires for them were can i get some for cheap i have try the local lkq but they donnt have any take offs i guess not many of our cars been wrecked yet thats good thing
