PREDATOR SHIFTTING I'm just curious what everyones setting their shift points at. Also, looking for a few pointers how to figure out where to set my MPH shift points at. My red line is 6400 and my RPM shift points are at 6200.
THANKS ALREADY

Re: PREDATOR SHIFTTING On a stock valvetrain? I wouldn't shift higher than 6,000rpm and rev limiter should be 6,200rpm. You won't get any more power out of a stock cam and springs by turning it higher and all your doing is risking damage to it.
Leave the MPH shift points where Predator puts them - what will you gain from changing them? They are only for part throttle ops.

Re: PREDATOR SHIFTTING Don't take this as authoritative, but when
I pushed my MPH shiftpoints up it seems the
trans kicks down earlier, which makes it a
little bit sportier in around-town driving.
I haven't fully explored the limits but bumping
MPH on the 1-2 from 40 to 45 seems to make a
pretty large difference in how 2-1 kicks. You
for sure would want the MPH value to be at
least the MPH@6000RPM that you run in each
gear, because as I understand the decision,
it's upshift at the first one you hit. Higher
MPH makes your upshift RPM-based at high throttle
and later at part throttle.
