first test & tune 2014 (2005 mustang gt)
no new personal best, but learning occurred :coolman:
Northern VA Mustang Club track rental at Mason-Dixon Dragway (MD) on Sat, April 12, 2014 (note date on the time slips below is incorrect). This was my first time out with skinny fronts (15" weld rts with 28" M/T ET fronts), the only real update from my runs last year (full details here).
ran a couple of 12.5's with 1.6x 60's (car 5 in the pic below), and while this doesn't best my quickest run last year at MIR, it does best my runs at Mason-Dixon last year:
I think it's fair to compare the numbers at Mason-Dixon from Sep 2013 to Apr 2014 to see the improvement with the 15" skinnies:
I used a paint pen to mark my rim and tire to see if there was any tire/rim movement - it slipped 1/8"
I mounted my gopro to my panhard bar so I could watch for tire slip; here's a look at a 1.65 sixty foot run slowed down 8x (I painted a 3" wide white stripe on the inside sidewall):

setup for these runs:
- cj springs
- strange single adj struts set to full loose
- strange single adj shocks +3 clicks from full loose
- UCA in upper hole
- LCA in middle hole on bmr relo bracket
- 4500 rpm launch
- 26x11.50-17LT M/T et street bias ply rear tires, 15psi cold
- full interior in place, gutted trunk
- 302 rwhp
- temps ranged from mid 50's to high 60's during my runs, and DA was 100-700 ft (approx)
My first three runs of the day I launched off the rev limiter (6500) and spun bad, 1.9x sixty foot times. For those launches I was running 18psi cold in the rear tires, and there wasn't really any rubber on the track yet.
I think the sweet spot for my setup will be 14-15psi in the rear tires, with the rear shocks on +3. I hope to be able to launch off the limiter at MIR - that track just flat out hooks.
This fall I plan to lose the passenger/rear seats and run the p/s delete short belt for my hero run.
Here's another vid (that corresponds with the time slip on the right posted above)
