Trying to get an idea of what mods can increase efficiency, or decrease parasitic/drive train losses.
I know a lighter drive shaft will and that UDPs will but what else? flywheel i assume?
Also does anyone have any numbers as to how much of a difference each makes.
Since i dont plan on going FI any time soon im wondering how i can both lighten my car and make it more efficient at the same time.

 

Add aluminum flywheel and lighter wheels to the mix...
