First time out with the new setup. I had everything pretty good tuning on the street from the EFI live scan tool, AEM wideband, and the sotp meter. I get to the track and on the first pass it spun just a little and pulled a 1.67 60'. I had to let out when I looked up at the wideband and seen an AFR of 15.5. That was 15.7 at 61mph. I added fuel for the next two passes but had to let out again b/c it was still really lean. Only made one full out pass with a little spin 1.71 60' and a 12.3 at 107mph . AFR was 14.1-14.2 with a bit of detonation and only 23* timing from knock retard. I really shouldn't have ran all out but I wanted to see if it would clear up since it runs perfect on the street. Forged pistons helped out there. Gonna see if I can find out why it's leaning out only from a dead stop with traction.

 

Doesn't really have to do with your fueling issue, nice 60ft btw. What slicks, suspension are you using??

Thanks

 

You cut a 1.7 60' on those tires in your sig???

 

Caltracs, stock shocks, 28x11.50 Hoosier QTP's on stockers, pulled sway bar.

 

what rims are you using for those slicks? Im assuming you just have 2" shackles out back?

 

nice time.. i'm hoping when i get a 60' like yours i'll get my e.t. down there too. i'm trapping 106mph with only 12.8

 

Stock cast. 2" shackles and modified hangers.

 

What slicks??
