Post HP loss in the Drivetrain & hardened mounts

Anyone got any hard numbers, guesses, dyno sheets, or educated opinions about efficient ways of reducing drivetrain loss in an RS?

How much of a HP gain, if any, can be gained from STi transmission/engine mounts and Group N hardened mounts, or both?

The engine/tranny mounts dont add hp. They are just stiffer so the drivrtrain moves less. It helps the power be a little more instant, not add any power. They also make the engine/tranny structual. They add stiffness to the chassis by tieing it to the engine/tranny. This helps you handle better. I have herd that they are great modifications and add greatly to the feel of the car.

Sure the stiffer mounts will reduce HP losses. Oh say on the order of .001HP??

Get them to keep the tranny from hitting the side of the tranny tunnel on a quick 1-2 shift.
