Over looked power.... Options

[macavely]

Is it me or alot of people over looking something that would give you a lot more power to the wheels with out having to do one thing to the engine... Droping your car off at a good tranny shop and letting them rebuild you transmission so you could have 95% of the engines power to the ground....has anyone tired this yet? or is going to try this? i know you guys doing swaps and turbos might really want to look into this.... cause whats the point of having all that power if your losing 30% in side the tranny....


let me know why you guys think?

the efficiency of the trans is not likely to increase by a lot. It would increase somewhat. The most effecient gear sets are planetary (auto trans) running around 98.5% on average. But for ever set you go through you have to multiply (98.5 x 98.5). Once the torque converter locks up in an auto tranny, your efficiency is ussually as good or better than a manual.

Gears in a standard transmission are less efficient than planets, but there is ussually only one set of gears that power is being transmitted through. In order to improve the effeciency all of the gears would have to be replaced and it would not be a large gain. a good exhaust would probably give you more gains.

Just does not seem like an economical source of power, that being said, synthetic trans fluid would be a good cheap improvement.
