I'm wondering what some of your 60' times are when launching in 4x4, and and I'm looking for ways to improve mine. I'm averaging a 1.9 in a 5500lb truck using the auto-trac. I'd sure like to get it lower.

 

I have a 4x4, but i don't spin in 2wd, so i leave it for less drag on the big end...2.05' with factory converter 3.90 gears and 4,500lbs

 

are you getting any wheel hop?

 

Just looked at my timeslips from last Friday night.

1.72
1.68
1.72
1.69

 

Usually 1.8 and a few 1.7's

 

1.69 n/a with a 5.3

Not bad 60s im wondering what mine will be stalling up boosting? Should be around the 1.6 area.

 

Most of mine are around 1.68-1.74, but I pulled one 1.61 out of nowhere once, but I did get it to stall to 9.5psi at the line that run. Usually I can't get it to get to 6psi.

 

1.81 was my best...

Launching in 4HI...

 

I get a little spin but no hop. I get the best time hitting it from an idle. I'm sure a higher stall would help but I need this thing as a tow rig, too. A little weight reduction would help, too.

AK, what does your truck weigh? How much did you save with the rollpan?
