I posted a while back about only laying down 364RWHP while running pig rich 142 shot on the dyno. That got me a 12.0 @ 115 earlier this year. I ran 12.05 @ 112.9 on an off the shelf 100 shot last year. Yesterday and Friday, I changed my jetting from .062N .036F to .062N .033F and ran some race gas to stay safe, since my Thursday dyno trip was unfruitful, due to a bad batch of gas . I ran 12.02, 12.04, 12.06, all @ 115mph. I ran on my BFG 295's and I ran on Z32's with Hoosier 26x9.5x16. Same times on both. Same mph. More consistent on the Hoosiers.
Best 60'
1.58-BFG
1.62-Hoosier
All on 6k rpm launches. Why wont it go any faster? I have a few hundred passes under my belt, but I'm stumped.

 

Weather?

 

Beat me to it.

 

about 65 degrees with ~50% humidity.

 

What about your previous runs.............man I wish it was 65 here.

 

Seems like the DA is what is killing you.

 

How do you know.....he hasn't mentioned what the weather was like his prior attempts...

 

i know its been hott and humid here..

1.5 60ft? stock axles? are you off the limiter or just dumping it from 6k? what are those bfg tires?

 

Stock axles, open diff. I give it a quick slip from 6k. I'm still scared to drop the clutch from 7k.
I run bfg drag radials on the street.

 

The early runs this year were made in 50* weather and 90% humidity.
