Default Another 1/4 mile record

I got super lucky and had ideal condition with a DA of -1800! I was consistently sub 12's all night and finally after the break was able to rip of a bunch of 11.7's with my best being an 11.74. The drag radials really helped in the 38 degree weather. I'm still shocked at how great our cars hot lap and how consistent they are. I made about 30 passes and 25 were sub 12. Unfortunately this was the last street night of the season at my track but I must say I couldn't be happier with my results. I went back in the spring just hoping to go below 12.2, 200-300 passes later and I have the NA record with 142k miles! Zero issues too our cars love the punishment.

Congrats Drok149. I actually wanted to go to my Raceway today but I had sooooo much work to do. I am very curious how my ISF runs with a blend of e85. Did you remove anything to lighten up the load?

140K+ miles and laying down 11.7s with bolt-ons, all NA.

LOVE THE ISF.

Congrats man! If only RR Racing tune could keep the TC locked up after 6800 rpms I could see you in the 11.6s or better. =)

Wow those are some ideal conditions you had!!! Awesome ET and 60' too, but surprised your mph was lower than before.

Also wondering what you use to calculate your DA? I use weatherunderground history and plug in the numbers with this calculator http://wahiduddin.net/calc/calc_da.htm.

Based on 90' elevation, 36F, 30.43 Altimeter Setting, 24.6 dew point I get -1972FT!!! That's insane!!!!

i used the DragTimes.com app I plugged it in around 730 and was at -1500 and knew it got a couple degrees cooler. -2000 is wild!
