Figured I would post these for your perusal.

First run of the day. Boost was set at 10psi just a shakedown pass.

60ft. 1.982
330 5.610
1/8 8.607
mph 82.32
1000 11.245
1/4 13.555
MPH 96.92

Wideband was reading ricer than 10:1, but i figured before i take fuel out, I would up the boost some. So i took her up some. This run was at ~15psi.

60ft 1.815
330 5.201
1/8 8.211
mph 83.64
1000 10.816
1/4 13.065
MPH 100.01

Figuring my 3rd run may have been the last of the day, I cranked the G-valve all the way in but, my boost was still limited.... ~20psi max

60 ft. 1.779
330 5.031
1/8 7.818
mph 86.87
1000 10.304
1/4 12.448
MPH 104.75


The last run of the day, I tried stretching the Gvalve spring some to see what it would do. Max boost 22psi.

60 ft. 1.749
330 4.929
1/8 7.639
mph 90.04
1000 10.045
1/4 12.128
MPH 107.75


Now generally, my traps seem a little low to me for the ET. I think this may have to do with the taller slicks (24.5 vs 23.5's) and the car struffling to accelerate in 3rd gear especially with the lower boost than i am usually running. We will have to see what comes of the taller slicks when more power is applied. Fuel always stayed richer than 10:1. With the final run being the richeset at 9.49:1 thru the traps. Looks like I have some room for tuning as far as fuel goes!

Maybe there was a head wind as well?

Wow that's hauling a$$. :nod: Is a 12.1 your best time in the little L-body??

FWIW, the 24.5" M&H's vs. the 23" M&H's on my stockass shadow ran the same mph but a tenth and a half quicker with the 23"s.

You're getting decent 60's is it spinning much out of the hole? if not, I think your lower mph with that ET is more of a result of a light car that the chassis is working decent on. Is it an automatic too right? That will run less mph vs. a stick car for sure.

Definitely got soem tuning left in it to go faster! :thumb:

What car and set up?

[8valves]

Awesome Mike!

You've got LOTS of power left in there with the AFR's that far south. Is this still on the 50 trim- and what ECU are you using now?

I see a whole bunch of potential there buddy!

Oh yea definatly! As rich as it was it still ran darn good! lean it out a bit and man i can easily see 11's with that car! good job!!

Thought I'd post mine for analysis. It was my first experience with a fwd standard shift car at the track. I know now, after talking to some of the TD guys I met at Cecil, that I was launching it wrong both runs. My second attempt I twisted an axle creating a viberation so I didn't run again having driven the car 126 miles to the track. This is on street radials...Nitto NT450 225x50x16
