Ran a new personal best today !

The weather was pretty good, but I have run in better air (mineshaft air). This was real close to zero density altitude, maybe minus 50 ft.

9.104 at 145.3 mph, 59ºF, 29%RH, 30.08"Hg

Earlier this year it went 9.175 at 144; 57ºF, 29%RH, 30.02"Hg
Previous best with this car on E85 was 9.158 at 143.2; 51ºF, 31%RH, 30.28"Hg
Best ever running race alky was 9.121 at 145.3 mph; 52ºF, 21%RH, 30.42"Hg
All these were with the Ron's Flying Toilet injection system.

And... today was through the mufflers! (4" straight thru bullets) LOL

And it looked real good running that fast. Good to see and talk to you today Jim. Car was really pulling some nice wheelstands. Ron

Thats a real car.

You have a really nice car.....and it works. Congrats.

How cool is that!

I got the setup right for the conditions around Noon on Sat.
I richened the fuel slightly, and made some minor chassis adjustments for controlling the expected power with the right weight transfer and wheelie bar setting.

As far as the bullet mufflers go, I did a back to back test last year. The headers are 2-1/8" x 32" long primaries with 4" collectors. The first pass was with the open headers. The second with the 4" dia collector extensions (~18"). The third was with these 4" dia bullet mufflers. The first two were the same, and the muffler run was only 0.02 seconds slower than the others. See the timeslips attached.

very nice, I always love new bests!!
My Dart went 1.166 60' in the final last week to bad I was slowing it down for 5.30index. I would've have LOVED to run that baby out!!

New bests are always cool.
Great tuning with your car.
E-85 sure is COOL eh? !
Jim do you have to use a chute?

Don

Jim, your back to back test might show more accurate gains/losses
if it were more consistant.

Congratulations on the new best. It's a very well put together
combination that you prove over and over.

A paracute is not required until 150 mph. And MIR has such a long shut down, even door cars going 160 don't use the chute they have, and dragsters are going 175 without pulling the chute.

Wayne, nice sixty foot (1.16); that is leaving the gate hard!
