really constructive post... they did post dyno sheets. i just wished that it showed the baseline run & after the pulley.
either way, its way overpriced.

That's interesting, the dyno is done by a tuning company here in Hong Kong though the poster states they are from LA, USA. Checking on the tuner shops site in HK all I see listed for Benz are H&R springs.

While the thread is up: Power Pulley Rules:
1) if just the weight is lightened, expect no improvement, as crank and fw/TC inertia will dominate.
2a) if underdriven, then max power will be in 1st gear, where highest acceleration of pulley and driven parts occurs, now with less acceleration.
2b) if underdriven, a slight improvement in steady state power at higher revs will be due to less power absorbed by driven devices, assuming each device has a constant resistive torque.
