Finally Sprayed it *track results and pictures* I've been building my car around nitrous for the last couple years. I had some ignition issues stop me from spraying it last year and finally got around to it today.
The kit is a Nitrous outlet lt1 plate kit with a dedicated fuel system. I only had 100 shot jets in it.
I worked on the car N/A to shake it down for its first 1/4 passes in a couple years.
NA with a nitrous tune it went:
1.57 60ft
4.566 330
7.14@94.7 1/8th
11.25@119.3
I came in tightened down the front shocks a couple clicks, added some air to the rear tires to get it ready for nitrous:
This is what I got in return:
I was caught of guard and feathered the throttle a bit much and did some pretty ugly damage to the headers this time slip wasnt pretty
1.49 60ft
4.42 330
6.85@100.87mph
11.367@93.5mph
I just did an 1/8th pull.
Next pass I tightened the front shocks all the way and came out with a small 12" lift and a nice straight leaving car. The nitrous bottle started to go empty the next couple passes. I went to the track not planning on spraying.
Time slip:
1.39 60ft
4.19 330
6.62@100.86mph
10.52@124.9mph
My wideband was reading 10.3-10.8 this pass.
LAST PASS
Changed fuel jets left the suspension alone:
1.43 60ft
4.25 330
6.71@99.9mph
10.65@125.47
The bottle was going empty on that pass but AFR on the wide band read 11.3 so its a step in the right direction

Pat its Cordova Since all the tracks are closed here in Iowa already. MWC did a private rental and allowed around roughly 85 cars in. Joe the reason it was a 1.49 is I backed out of it so soon it really caught my off guard.
So far the damage is Headers (fixable), Scraped up back bumped..not worried about it, Dinged up/tweaked tubular lower radiator support, And I have a small water drip some where I need to find hopefully it didnt hurt the radiator but I do have all winter to fix it.
Wicked BR7EFS gapped at .031. They are the plug I run for NA. and I felt they were safe enough to spray 100 shot on. I was planning on spraying more this year and had BR8s in it gapped at .028 but fouled them during tuning and the 7s were all I had left on the shelf. Timing was 32-33*
Also race weight was 3600lbs with me in it and a full tank of gas.

congrats bro. Whats funny even my camaro had a cam only spray car and was doing 1.39-1.42 short times and NEVER had wheels up like your car did. I was lucky to get 3" off the ground. Difference was it ran 10.6s. But I would have like some wheelies too.
