Mph is hp to push the aerodynamic brick through the traps.

ET is the efficiency to get to the end.

Basically stock 1997 Ford Probe. Unfortunately the mph didn't print properly on my time slip, but it looks like 80.xx mph. The best of my other runs was 79.99 mph.

Interestingly, this was my first run, and it wasn't dark yet, so I accidentally ran with headlights off. Meaning, no aerodynamically problematic popups on my best run.

I wonder if anyone has studied the aerodynamic effects of popup headlights. (I'm sure someone has.)

It's also possible, though, that the first run was the best because I was trying too hard on every run after that and messing it up...

my bone stock 96 PGT went 15.21 at 89 on A6's at 13 psi.  your 60' says you're either leaving too gently or you're spinning.  i'm pretty sure my 60' was around 2.2

Very possible on the spinning. I was on crappy all-seasons and unknown tire pressure. On one of the later runs I tried to launch with some RPM and had tons of wheelspin.

My second-best run (17.435) had a 60' of 2.508, actually...that run was faster to the 1/8th but was already losing MPH compared to the 17.391 run.

Chalk it up to a combination of tires, bad shifting, bad launching, and overall lack of driver skill. laugh
