just wondering this because im racing an 05 mustang gt 5 speed with full bolt ons, comp stage 3 cam package, rouch suspension, and 3.90 gears....anyone have any imput about how this race will end vs. my full bolt on camaro with only SFCs for suspension work...(both cars hook)
Setting them at 6200 will be good. They usually happen a little later than commanded. If you had a stall or nitrous you would probably want them set a little earlier. My 2>3 is set for 5900 but actually happens ~6300.
Hard to say about the race. I've seen an 05 GT with a 5 speed and a 100 shot run 12.7s with a 1.7 60'. You should be right on that (I'm assuming that you don't have a stall).

I would data log it to see where it is actually shifting at.
I found that 6,400 for a auto with a stock cam gave the best ET and MPH.
With a after market cam you should be close to 7,000

alright i went to bump up my shift points with my handheld programmer and instead of adjusting by rpm it only adjust by MPH so i bumped up my 1-2 shift and my 2-3 shift by 2mph and i also bumped my rev limiter up by 300rpm and increased my shift firmness...does this sound like the ring thing to do (2mph thing) or am i way off ?
