Question on 1/4 mile times/launching
So I did 21 runs tonight with various techniques to see what worked out the best. I ran a ton of 14.2's, one 14.6 after a horrible launch and three sub 14's. My best was a 13.77. So here are my thoughts and I'd like your thoughts on it.
1: If you have a 5spd auto leave it in D. There is no benefit to putting it in manual or trying to shift yourself in the quarter. All of my sub 14's where in D. The TCU shifts at redline for 1st and 2nd, although I think it hits early on the 3-4 upshift this has no effect on the results.
2: My best runs where done by going straight from brake to gas. No powerbraking or other engine reving, just modulation of the pedal on take off.
3: The quickest runs where done with no wheel chirping. Since I'm new at 1/4 mile runs I didn't know how much chirping was good/bad. Obviously it bogs if your too polite with the throttle but too much didn't help. My best where done when I felt the wheels just begin to slip on take off but didn't chirp and then hooked up completely and I floored it.
These are my impressions and I'd like any input from you guys on my findings or better ways to launch.
On an ironic or just note depending on how you look at it, I was clocked 6 seconds after my last run of the night doing 97 while coasting and was promptly pulled over at 2:30 am. Not mad about it, but thought it was an amusing turn of events. 50 feet from my exit and ready to call it a night. Just another reason to only go to the track for timed runs.
