so since my 13.2 @ 107 ive added underdrive pullies and a JLT intake with a custom dyno tune. 12.75 A/F ratio across the board, 322 to the wheels (uncorrected) ~295rwhp corrected.

went to the track tonight and didn improve my time into the 12s...bummer...

BUT, did get it from 13.26 down to 13.11
and my trap went from 106.7 to 109.8 THREE MPH pickup
60' was 2.03


the pullied/intaked/exhausted 03 cobra had a tough time pullin on me...ran with him 3 times and lost by ~.15 each time with <.5mph diff in trap

all i have to say is IT WAS FLIPPIN HOT probly 102*, and in direct sunlight and shiz we were toastin.

 

Improve those 60ft times and you'd be in the 12's.
Someone correct me if I'm wrong but I believe it was generally for every tenth you improve on you 60ft, you imprve 3 tenths on the 1/4.

but, man that weather was holding you back, so I think those times are amazing for the circumstances.

 

Great ET Geoff, but WOW, that trap speed is phenomenal. :worship: Are you guys running down hill over there?

With some stickier meats, you'll be well in the 12's for sure. What tires are you running? Speed shifting? Do tell.

 

That's impressive! With some cooler weather your mph and ET should improve. What track do you run at? Must be one of those freak tracks.

Also, can you post your slips or post the incremental measurements? I am interested in the mph gains between the 1/8th and 1/4.

 

I'ver heard it's more like .2 for every .1

 

How did you get it "dyno tuned", what software did they use? I need to get mine tuned. This Predator that came with the Paxton is garbage. under 10.0 A/F in most places... :nono:

 

that's some mighty fine driving. if you can get your 60' time to 2.0 you should end up well into the 12's. what rpm did you launch at? i assume you didn't have to much if any spin? regardless i bet the cobra guy was tripping

last, really? those are you're only mods? your car must have been built on a tuesday

 

very impressive. With some sticky tires you would be well into the 12s. Cobra dude must have been sweating.

 

i got it done by keith and Force Fed Performance in Roseville, Ca using SCT software on an Xcalibrator2. race was at Sacramento Raceway. the track stinkED, reason i was hooking at all was lots of practice, 255/50/zr BF Goodrich KDWs at 17psi. i was powershifting for sure, at around 6300rpm.

What really confuses me tho is that my 60' dropped from 2.07 on stock tires and all to 2.03, so not much change...and my trap jumped over 3mph...but my ET only improved .15?

i luckily had a white slip for my best run!! so i will do my best to get it posted...probly a pic with my camera phone...don have access to a scanner. (don wry, its a 1.5mgpixel camera)
