ASW---I am refering to the thrust at the rear wheel--
So am I.
by using the higher number ratio you get a larger number at the wheel because of the larger gear multiplier---
Of course. Gearing multiplies torque. The more rpm you turn at the engine, the more gear reduction you can apply for a given rear wheel rpm, hence the more you can multiply the torque. I understand all that.
vs gearing for peak torgue---you have a bigger number to the trans and rear axle---but loose it by the smaller rear gear multiplier---you can multiply torque---but not HP---bottom line---its all about what you can put to the ground and hook up.---
Here's where you lose me.
Torque and rpm are interchangeable entities. Gear taller, you give up rear wheel torque but gain rear wheel rpm, and you do so by equal factors. Gear shorter, you gain rear wheel torque but you give up rear wheel rpm, and again, you do so by equal factors.
Because they're totally interchangeable, each of these two items, torque and rpm, are weighted the same in the horsepower formula. Horsepower is literally torque times rpm. They make an equal contribution to the performance because they're totally interchangeable. And they make absolutely equivalent contributions to the performance. So horsepower describes performance.
When you're at your power peak rpm, that's the point where the total combination of torque and rpm are at their greatest. This notion that you can run your motor
past it's power peak rpm, and then gear shorter such that you get back to the same rear wheel rpm you had at the power peak, and end up with a
higher combination of torque and rpm at the wheel than you had before, is patently false. If you could do that, you would be raising horsepower with gearing, because your total combination of torque & rpm would be higher on the downstream side of the gearing. Gearing can't raise horsepower, it can only change the mixture of torque and rpm that makes up the horsepower.
Bottom line, the power peak rpm of the engine represents the point where the combination of engine rpm and torque are at their highest. You cannot artificially create a higher combination by revving higher and gearing deeper.
If you're still convinced there's something to be gained by revving past the power peak and gearing deeper, give me an example. I can show mathematically that it doesn't work.
