How does cid make power?

You post says shift point of 6k and 8k. I'm not a drag racer but don't you shift at some rpm past peak usually? That part doesn't matter. You're saying now that the motors make the same power only at peak for each motor 6k and 8k? Wouldn't the rest of the curve matter as to how the car performs?

It depends. And most of it depends on the engine builder. I guess there should be a qualification on what transmission is used.

If they are powerglide cars, then I’d want the power to hang on past peak longer. You want to stay above peak torque when your RPM fall back on the shift.

If it’s a 3 speed you can narrow up the power curve a bit but you lose power past peak. Once you go to 4 or better yet 5 gears, then you can narrow up the power curve even tighter. And that means you won’t have as much power past peak.

The latter two scenarios make the car harder to drive. You can’t short shift or the engine drops below peak torque and it’s a pig off the gear change.

Shift late and the power falls off so fast the car actually slows down before the shift. You can see this on a G meter if you data log.
