So close but no cigar.
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.

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.
