Decided to jet up the nitrous system to a 75 shot and headed to the 1/8th mile track.
First run, I tried to spray out of the hole but it spun bad so I lifted and just cruised down the track to a 8.66.
Second pass, made a boost only run to make sure everything was in check. Ran 6.97@ 99 with a 1.57 60'.
Third pass, I decided to do a heavier burnout because it was only about 70 degrees outside. I sprayed just long enough to get up on the converter and then let off the button. I launched the car and about 60' out I hit the button again and rode it all the way down the track.
I ran a 6.67@106 with a 1.58 60'. New best!

Fourth run, I decided to try and spray about 1/2 second after releasing the t-brake to give it a chance to hook. All went well until I got down track and the car started getting way out of shape so I lifted. Ran 7.16@77 with a 1.52 60' on that one. My 330' time indicates it could have been a 6.5X pass if I didn't lift, but I would like to keep the car off the walls, lol!
I noticed that while on spray, the AFR was too lean. It was in the 12.4-12.7 area and I felt a couple of misfires during the runs. I jetted up the fuel side of the N20 system twice and it made no difference so I guess I have maxed out my stock fuel lines once and for all.
