I know I am in KS where NA cars struggle to make power, but my MPH is way off from some of you other similar NA guys???
I should be making some of my first ever Nitrous passes this Friday night if the weather holds out.
I have had several 60's down to 1.71-1.72 but haven't posted anything as I am really wanting to get 1.6X something. In two weeks our track will have the best prep of the year as it is a large race with Pro Mod's, 10.5, A-fuel, and a Top Fuel exhibition, but it will literally be probably around 100 degrees so overall times will suck.
BRING ON THE FALL COOL AIR!!!

Good luck! I have no doubt that you'll be in the 1.6x range on the juice, but it is tough to do on "bolt-on" power and stock-ish weight. I see 1.71-1.72 as about as good as 60s get without getting into heads/cams and or power adders with these cars.
It would be cool to see people post more times even if they aren't "impressive." It's not just about posting up a number.

Everything same as before but on a 75 shot I went a best of 12.997 @ 106.5mph, 60 were not too good as on a Friday night T&T they don't prep well and the nitrous is not activating until 4500 which puts me past the 60 before it activates.
I didn't realize until learning the hard way that bottle pressure really affects the AFR after the first two passes when I started to get things dialed in the bottle pressure fell to 850 and caused me to go ridiculously rich. Bottle heater already on order!

04 cobra ran a 12.9 this past weekend at local track, 12.9 with a 132 trap speed, he lost to a mild srt4 neon..... kinda sad..........people need to realize you race cars not dyno slips, who give a F about the trap speed he still lost.

Well over the weekend I had several new personal bests!!! Finally got a 1.69 60' on motor!!! this was on nitrous passes but in order to slow down to 13.0 for index I have first gear locked out of the Nitrous window switch. 12.82 @ 108 on the 75 shot, but still needs some fine tuning. Won a Wally in the Index class running 13.0 index.
I will post the timeslips if I can find them in the disaster that is my trailer...
