Lighter components such as flywheel, clutch, driveshaft, wheels, rotors, basically whatever stands in the way of the power getting to the wheels will reduce loss.Originally Posted by HvyArms
For instance I went with a lightweight clutch and flywheel on my Infiniti G35, the car is rated at 280hp measured at the flywheel but actually put down around 222hp to the wheels with the stock clutch and flywheel. After going with an Clutch/Flywheel assembly that was roughly 30lbs lighter the car put down around 238hp to the wheels.. it didnt add any horsepower, it just reduced the loss of horsepower through the drivetrain and greatly improved engine response. The downside was it was hard as hell to drive daily.
As it pertained to G35's, automatics see more drivetrain loss than manuals but I'm not sure about other vehicles. Hope this helped.
