Has anyone heard of modifying the drivetrain to cause more of the 306 hp to make it to the wheels?

 

If you're talking about increasing driveline efficiency, there probably won't be too much you can do.

The only thing I can think of would be lighter weight components such as aluminum or CF driveshaft, lighter flywheel, rotors, hubs, etc.

 

go get your auto clutch rebuilt with lighter, stronger parts

 

manual conversion. though i doubt itll happen...

 

how much would an aluminum driveshaft cost? what are the pros/cons?

 

Lite weight wheels and tires would be the place to start. Our automatic doesn't have a clutch at all, and a lightened custom prop shaft would be a small bang for the buck IMO.

 

might not be more horsepower, but a different rear end gear ratio would probably make the car quicker.
