2wd 60 ft. times
- Thread starter sandsuby
- Start date
Finally getting my 60' times down - went 1.63 last night on an 11.40 pass. Leaving around 6-8psi of boost running a 33x10.5 Mickey Thompson and CalTracs. With some more adjusting on the front shocks and a better launch I feel a 1.5X is very attainable. The 330' time = 4.727, 1/8 = 7.339, 1000' = 9.593. That was with the A5k and stock injectors still in the motor while I break it in. Won the race as well.
On a side note, I made several launches leaving in second gear (building more boost) but had to abort several passes as the truck went into tire shake right off the line. It felt pretty violent in the cab and the guys said you could see the slicks sucking up pretty hard. The Allison didn't like that at all and would not shift out of second (I believe the code referenced the vehicle speed sensor) so with the rpm it was turning the two did not match up and it threw a code.

Congrats on the win, Watch the second gear launches. It will smoke your tranny. Are you still runing the 4.56 gears? A video would be awesome 
I am working on getting videos from last night. I still have the 4.56 gears installed - they work very well.
When I launch in 2wd to mess around the best so far that ive got is a 2.2 60ft without doing a burn out on nitto Terra grapps. Leaving at no lbs of boost.
1.60 60' time last Friday night test-n-tune. I am going again this Friday and then swapping in a fresh trans before Topeka.
