I took the truck to the local 1/8th mile tonight to go after that 6.99 I've been shooting for. I found the limit of my cheap *** Firestone tires on almost every pass. I never thought I would have traction issues in 4wd but I actually have rubber all over my doors from the front tires. I actually got sideways about 100' out on one run and had to back out of it and keep it out of the wall. Details are in my sig and I was running 14.5-15psi, 18 degrees of timing with a 5100lb race weight. Best pass of the night went like this.

60' 1.632 4psi launch with a little wheel spin
330' 4.697
1/8th 7.099
MPH 97.44

I ran a bunch of 7.16's spinning. Anything over 4psi on the launch would blow the tires off. I think it would easily go 6.80's or better with a better set of tires. Maybe next time.

Videos of the last two passes.

Nice runs, pics of the truck?

 

Get some nitto 555r on all 4 corners and you'll get it. Nice run.

 

Thanks. I don't have any pics on my computer but their are some old videos of it in my sig. It looks completely stock other than missing the tail gate.

 

I haven't looked at them yet. I've been looking at MT drag radials and can't find a size that would work. Good idea.

 

Damn, so close! You know the truck will do it, you just need to get it to the ground!

 

ahh so close! get'r to plant and youre there !

 

Awesome man! Are you going to try new tires this fall?

 

Thanks. Can't afford new tires this year. Stock48 is sending me a bigger downpipe that he said will help. Going to strap the front end down and mess with tire pressure a little and see if that will help. Over the winter It's getting ported heads and a new cam so that should help a little too.
