My engine makes max HP at 6400 RPM, so when i want to manually shift it while racing what should my rpms be around?

youll have to play with it but i would try 6000 for now and go from there

I set my shift light about 200 RPMs LESS THAN where I actually want the shift to occur...that way if I'm a little slow reacting, the shift is still where I want it to be. It'll take some trial & error.

Some of it depends on how much RPM drop you get on the shift to the next gear. You want to keep the engine in it's max performance band. I set our air shifter at or a couple hundred RPM above the max hp RPM that we found on the dyno. You will have to do some experimenting at the track to determine the optimum shift point as it definitely affects your final ET/Speed.

i agree with you. we found about 500 above max power we run the fastest. we played with severl cars on the dyno and found similar results.


if your still building power why shift early, use the power you have

What rpm does your engine build the most torque? Dave

 

[bowtie0069]

Mine makes peak power at 68-6900 and I usually shift at 72-7400

Need more info. Engine, convertor, trap rpm. Dave
