I went back out to Rock Falls Raceway this morning, which is at about 850ft of elevation, ambient temp was about 68F. I was running 3/4 tank of 93 octane.
I have to say I'm pretty happy with that. Using Copper's launch technique, I was able to shave over .2 off of my 60ft, and .8 off of my overall ET. Here's a couple of videos taken of my 3rd and 4th runs (after heat started to take it's toll).
