I wanted to test out a few things while I was at the track tonight and since there wasn't many racers there, I thought it would be a good time to.

I first tried removing the head light, to let air 'ram' into the cone. On a back to back run with a 10 minute cool down inbetween, I ran the exact same time. This is on a N/A pass, no nitrous and in overdrive.

Removed head light:14.177 @ 93.52 (2.0 60')
In place:14.187 @ 93.54 (1.96 60')


Next,

I tried full exhaust vs. open cut-outs. For starters, I have Thorley long tubes with a dynomax dual in/dual out muffler, ran in 2.5 inches with no cats. After the headers lie the cut-outs.
With a 50 shot which should app. put me at 330rwhp.

Full exhaust:13.861 @ 98.30 (2.1 60')
Open:13.976 @ 98.82 (2.2 60')

Just my tests that I thought I would share... If this isn't accurate enough for you, do your own.

well that sux i thought the cutouts would help, nice runs though

 

Did you ever best the 12.9 run?

 

Nope, some of the front wheel drive guys kept slicking up the take off.

 

excuses kyle, just plain excuses.. haha j/k

pretty interesting results though.

 

Interesting! Do you think if you had pulled a 2.1 60ft w/ the cut outs open that it would have bested the run w/ them closed? Cuz it appears your trap was slightly higher with them open although the higher trap could be attributed to a number of variables.

Good to know though....oh and that truck sounds frkn sick.

 

Hey sportside i've done the same thing but got 2/10's better times with the cutouts open and with the light out and mirrors folded in only neted me .05 better in the 1/4.
