In case you get no proven response and based on photos and video it appears to be real close 1/5 th mile, starting with a 17/62 should be pretty close expecting to have to lower rear gear for race, I think you'll end up on an 18 driver as it appears it makes good momentum and provided your driver runs it 100 %, I'd have a 16 front driver along as well just in case. Hopefully someone with proven experience there will chime in.

Good Luck !!
