M8 track testing
« on: April 16, 2018, 08:11:06 AM »
Gained 3 mph, lost et. My riding was a little suspect, even taking off a tenth it's not what I was hoping for. Left lane, 2017 117ci flhx. Right lane slick tire care, cut a .0008 light, wtf. Keystone 04/14/2018

You are a lucky man getting in a track day already. How many runs did you get?

Not that lucky, my local track can't open with the weather. Drove 300 miles one way for 4 runs. Didn't do what I wanted but at least I have a direction.

Were you running the set up from the dyno graph in this thread?

Compared to the slip in the dyno section, You have a consistent 60' and you were quicker at the 330.
Did you use different shift points for these runs?

Looks to have come out of the hole as strong, I would next try a run with short shifting followed by a run with high rpm shifting and compare the incremental times.

Good ideas and you could be right. I'm making changes, not ci, compression or weight. Goal is 6.77 1/8's 10.70's 1/4. Want to mess up and run 10's

Based on your best incremental times from the last two runs you have a 10.698
If you could have pulled that 1.565 60' time on the time slip from Feb 17 at Silver Dollar you would have a 10.484. All of the increments were faster on that run, what did you change between then and now?
