Hit up the track last night for the first time on the 100shot..
Detuned back to stock fuel trim and timing with the predator, I also have no bottle heater so I never had enough n2o pressure. Stayed around 850-900psi. Running on 275/60/15 ET Streets on 15x7 v6 wheels with mods in sig.

diablo tune, not enough heat on the DRs, left OD engaged
r/t: .508, 60': 2.115, 1/8th: [email protected], 1/4: [email protected]

factory tune, decent hook, 100shot @ 900psi
r/t: .624, 60': 2.070, 1/8th: [email protected], 1/4: [email protected]

DR's spun and hopped
r/t: .681, 60': 2.159, 1/8th: [email protected], 1/4: [email protected]

factory tune, OD locked out, but forgot to arm n2o after burnout (doh)
r/t: .328, 60': 2.088, 1/8th: [email protected], 1/4: [email protected]

Let the car sit for a while, ECT cooled to 150*. Raced against friends in a camry, got hooked and ............................12.8! I got down to the time booth and the f@#king ticket printer was broken. I didnt know what I had run until my friends pulled up beside me and said 'Dude. You just ran a TWELVE EIGHT!'. Pulled back around to the staging lanes and asked another friend at the burnout box what I ran 'Like 12.8 at 106mph dude'. So sadly, my first (and only so far) 12 second pass I have no recorded proof of :(

BUT, I did back up 2 13.0's:

r/t: .402, 60': 2.038, 1/8th: 8.482@(blank?)mph, 1/4: [email protected]
r/t: .472, 60': 2.089, 1/8th: 8.528@(blank?)mph, 1/4: [email protected]




I have a good bit of room for improvement, right now the spray cuts out at 5500, and I'm crossing the traps screaming with all 3rd gear has just before the limiter.. I could spray a little longer and might see as low as 12.6.
 
man i really need a set of DR's. i was running 13.1's on street tires with some ugly 60 ft times. like 1.90's. those are some great runs. props. maybe i can get there one day.

Nice! I will be getting my nitrous kit for Christmas this year. I am running an auto with a Predator too. Did you have to get a custom tune to run with the bottle?

I put the timing and fuel trim back to stock for the n2o runs.. if you have your car predator tuned NA on the dyno, you should check it on the dyno WITH n2o before you spray or revert it to stock.. most nitrous kits are made for plug-n-play for factory cars with minor mods.
