i ran the car again last night. the weather was atrocious... temp was 90 with 90% humidity and elevation is 1744. that makes for a density altitude of about 4500

1st run (car had cooled for about an hour)
drag radials 17psi and cutout closed
12.43 at 109.9 with a 1.82 sixty foot.

2nd run (car only cooled off for 5 minutes while i uncapped the cutouts)
still on drag radials 17psi
12.59 at 110.8 with a 2.02 sixty foot

3rd run (car cooled for 2 hours, the temp was down to 70 and the sun was down)
bolted on the et streets at 15psi
12.42 at 109.7 with a 1.86 sixty foot

4th run (car cooled for about 30 minutes)
tire pressure down to 13psi and did a longer burnout
12.22 at 110.4 with a 1.73 sixty foot

i wish i could run this car at sea level with decent weather, hello 11's

Wow, I didnt think tire pressure did that much.

 

track prep was non existant. the only time the car hooked up was on the 12.22 run. i did a 15-20 second burnout in 2nd gear and the car dead hooked.

i get the best sixty foot when i just stall it up to about 12-1400rpm...and then NAIL it

as far as tire pressure goes, im betting 15psi would have dead hooked if i had did a longer burnout...
those et streets like the heat

That's an awesome time in a vert man...I wish the conditions would have been a bit more favorable for ya so you could have seen 11s. Maybe next time

 

it will be late sep to oct before we get good racing weather....
i have to get a roll bar

 

4th run (car cooled for about 30 minutes)
tire pressure down to 13psi and did a longer burnout
12.22 at 110.4 with a 1.73 sixty foot

 

very nice

 

Nice times ... I wish you lived a little closer i would love to run you just to see the who would win.... My best N/A was 12.30@112.15 with a 1.874 sixty foot conditions were about the same....Congrats again...

 

i would be a good race, btw what was the DA on your run?
last november i came up to cincinnati to meet up with atljar and we ran at edgewater dragway. the weather was perfect, 40degrees, low humidy, elevation 492.
the DA was like -1000 or something
i ran a 12.5 at 115.4 with a bad sixty foot of 2.05, if i could have made a few more runs i would have hit 11's for sure. but i got kicked off for no rollbar....
since then i have went from mids to longtube headers, 48 to 58mm TB, ASP ud pulley, 24lb to 42lb injectors, and the car has lost 150-175lbs...and yet my traps have only been 110 this year....

 

Sounds like your car runs real strong... I have a brother that lives in Cinci... But i have the same problem as you do no cage and their never will be.... What did your car dyno? I still need to get mine on the dyno and check the air/fuel still on the mail order tune I'm not sure on the d/a that day but the conditions were track was 663 above sea level, and 65* with 70% humidity not sure on the bara... Let me know if you came to Cinci... I am getting a tune in a couple of weeks....

 

i wont be in cin anytime soon, its like a 6 hour drive for me...
i had my car on the dyno last fall with a failing stock fuel pump and before i changed headers, etc. it was 356hp/349rwtq, i was losing 10+ psi of fuel pressure above 5k rpm. at that time i ran at bristol and only ran 14.4 at 105 with a 2.48 sixty foot. (on street tires)
after that i changed to a walbro 255 pump and got some drag radials and ran 12.5 at 115.

i plan to dyno in a few weeks.

Wow jesse, 12.2s in that kind of weather is AWESOME. Great runs.

 

thanks jared, hopefully it will go faster later this year, im entertaining the idea of n20 again...

 

one of my buddy's trapped 99 at this track on that night, he went to richmond at raced a week later and trap 105...,
thanks amazing that he gained that much mph by going to a different track (lower elevation)

 

Wish I could get down to 4,500 elevation....
