On the SRX it seems well known that a straight shift is not the best. You want the rpm's to climb from about 8200 to 8500 during the shift out. My question is does this theory work on any other sleds? Don't most 2 strokes have the peak torque a few hundred rpm below the peak hp?

anybody?

it works fine for sleds w/lots of torque and power, like a srx 700. the over-rev before the straight shift starts, is for smaller-peakier engines like 440's.

So what sleds does this work for besides the SRX? Stock Viper? Or does it need pipes or other mods for this to work?

In aaen books he reccommends a slight over rev on top end so that if it gets dragged down by conditions it will fall right to peak. Atleast that is my memory of the explanation.
I read you other posts and I don't think you are using the wrong terms. Straight is usually referring to the helix angles.. If you are talking about shift curves I think that you can make straight angles and multi angles look the same on a shift curve graph.

yep, my aaen book also calls for the slight over-rev too, but i don't really like that. i personally like the rpms to climb either 200 rpm to the peak, or hit the peak rpms and just hold it.
