When you planning on running again?

 

[foxman92]

idk yet.. maybe next weekend or the weekend after that.. i need to do some data logging on a pass, so my tuner can look at it.

What elevation is your track at? Also teh Da on the day of the run? That will affect the outcome as well.

However, your results are good for your first outing.

it shows the altitude at 619'

well today i went to the local 1/4 mile track, and this was my very first pass in my cobra!! first time taking this car to the track. and i have to say im pretty happy for now.. its a stiegmier stage 5 with 2.76 upper only car, and other mods.. i ran a 11.52 on the first pass at 115mph.. i cut 1.6 60's on all 4 passes i made.. anyone else running these times or faster with upper only cars? i will try to take a pic of my slip and post it up..

I ran a 11.91 at 117 with an un-ported blower and a 2.93 upper with a 3000 ft da.

well i swapped rearends out today, put my 31 spline stuff in this other one, and its quiet so far lol.. i hope i got that issue fixed!!! but i called travis today, and he told me to data log a pass, and he will fix it.. either email me a new tune, or take it all the way back down there to him.. he said i should be atleast 120-123 for sure.. he is a great guy i think, since he hasnt charged me to adjust my tune yet! others around here sure would have..lol
