I have a Vig3200. When are you guys locking them up? With 3.23s locking it was not helping ETs or MPH, probably dropping RPM too much. With my new 3.73s I now go thru the traps at about 6000 (unlocked).

I was thinking 5500ish? Thanks for your help.

 

Depends on your dyno unlocked vs locked. I lock it up at 5000 with 3.23s.

 

Yeah, I need to get it dynoed. Then experiment at the track locking at different RPMs.
