As Tom Wilson put it...
- can transmit 36% more torque
No need to sell a bridge that doesn't exist, Phill. This shaft allows more power - period.
You *do* realize what "can transmit 36% more torque" means, right?
It means it is 36% stronger, not that it increases torque by 36%.
Torque is defined as Twisting Force...if anyone thinks that changing from a heavy shaft to a lighter shaft can increase TWISTING FORCE, let alone by 36%, they might want to take a basic physics class.
You'll get *no* argument from me that the new Carbon Fiber 1-pc. driveshaft is lighter and stronger than the previous steel 2-pc w/center carrier bearing. That's a given. I can't say if it's 36% stronger but I'll take "Tom Wilson's" (whoever that may be) word for it.
My argument is that it will give you enough horsepower increase to be measureable.
The way a dyno works is by timing how long it takes to spin a drum up so the faster you spin the drum up, the more HP the vehicle is producing (in theroy). A lighter DS will allow the engine to spin the drum up faster, but not so much faster as to be measurable.
Alex says he has seen anywhere from 7-15 HP increase. That's well within the 'fudge factor' on any dyno out there. And I've yet to see the comparison dyno sheets.
In fact, I've yet to see ANY scientific evidence that says a 1-pc carbon fiber driveshaft will give you ANY increase in horsepower, let alone any measureable increase and that would be easy to do, if it were possible.
