Look at a dyno sheet, this will tell you, without a doubt, where a good point to shift would be. The hp and tourque curve begin to go flat and/or actually decline, so winding past redline in most cases, even if the engine seems it will keep going, allows you to LOSE hp and tourqe, not to mention put undue stress and pressure on engine and running gear components.

It's still not exactly useful without knowledge of the gear ratio you are in, if the gear ratio is such that the mechanical advantage is still resulting in greater torque @ the rear wheels than you would have with an upshift putting your engine in the meatier part of it's power band, it will still be advantageous to continue revving in your current gear, regardless of the power dropping.



shift up and you lose mechanical advantage (torque multiplication).

of course, mostly a generic reply on my part. grossly exceeding redline leaves a disadvantage to most.

They had the radiator cap off. And it was already blown.
