+1

You will get a little gain from the reduction in rotational mass and drag from the accessories. There have been guys who have done dynos with these and the gain #'s are very low. The real-world gains are a bit better.

The UR site says that most of the gains are from the reduction in weight and not from the underdrive.

I still vote "no". Save your money for better mods.

Fluidamper FTW. Better than stock crank dampening, safer for extended high rpm operation and tip-in throttle application, and improved valvetrain operation.
