stillen lightweight crank pulley

I wouldn't necessarily say "more torque", but it's more than just revving quicker unloaded. It's hard to describe. The engine simply has less inertia to overcome on changes is the bottom line. It reacts to throttle changes under load (especially changes between accel + decel while staying in gear) faster. You could think of it as if the computer were inserting some very tiny electronic lag between the gas pedal and the actual throttles (or vvel, whatever), and the pulley took that away.

Butt dyno says some hps gains at the top end too, but no real dyno to confirm that yet.
