This maybe a stupid question but Im trying to figure out the best shift point for my car. My peak HP is at 6200 but is just about the same from 5700 on. Peak torque is at 4700.

Are you better off shifting at, slightly before or right after peak power? With my auto last year I had the shift point 200 rpms past peak power.

Thanks.

 

PDM: After...

But, its best to take it to the track .

 

How much after? 100 rpms, 200 rpms?

I only race at the track Ryan.

 

depends on your torque curve more than anything else. also, what transmission, rear gearing and do you have dyno output? can you give us a torque and hp plot from 2,000 rpm on up at 500-1,000 rpm increments?
thanks

try 300-400rpm past peak power. that is a good rule of thumb to start.

 

Tranny is T56 and rear end gears are 3.42's. I dont have the dyno chart handy, Ill post it tommorow when Im home.

Jason, Ill have to try that.
