Baseline on motor last night was 13.15@105.68 (3558# raceweight). Density altitude was 907ft on that pass.

With a 75 dry shot, ran a 12.508@111.21. Gave me a good 6 tenth reduction in ET and 5.5MPH. I think I can get more by upping my fuel tee jet size 2-3 sizes. My wideband was showing around 11.5:1 with the nitrous. I am running jet settings for 19# injectors but I have 30# injectors.

I was happy with the results, but I think I can do better. My best 60' of the night was a 1.83 on 26x10.5 ET Streets. Car kept losing traction when the nitrous hit. On motor I had a 1.85 60'.

Not sure if I can get this thing to run high 11s at its current weight with the 75shot, might get close though with very nice weather.

Nice numbers, now get that thing to hook! What pressure were you running in the ET Streets? They can go all the way down to 12.5-13 psi without spinning on the rim. I run mine at 13 all the time on the track. You have to be gentle with the steering wheel, especially on the big end, but they hook really well. You've got enough mph for low 12s right now, just shift it hard and make it hook! You are right though, you'll probably pick up by taking out some fuel on the nitrous, I never could get my old dry kit working right with the bigger injectors, but I never played with the fuel jets at all. I ran the factory type jetting and was running 24 lbers, then 30 lbers, with no luck. I switched to a single fogger nozzle wet kit and will never go back dry now except maybe if I do a two stage.

I was running 15 psi in them. I should have lowered it more. I will start at 14psi next time out and see how it responds.
