I was wondering if anyone has seen or done a before and after dyno testing on the stock steel driveshaft vs. FRPP aluminum driveshaft or even the carbon fiber driveshaft ?
In theory less rotating mass should free up HP, but can it be measured on the dyno ? I have never seen this done in any car magazine and it doesn't make any sense as to why not. It such a common mod, but I have never seen any tangible results.
I had heard that you can gain a tenth at the track from swapping the steel for the aluminum driveshaft. Has anybody experienced this for real ?
I am considering purchasing a frpp aluminum driveshaft, but I am going to be sure that the results can be appreciably measured on a dyno or at the track.
If it is printed in a advertisement page in a car magazine that it adds HP, blah , blah....Then I am going to go out of my way not to buy it, because aftermarket manufacturers grossly exaggerate the performance gains of their products to the point of absurdity.
