Our Underdrive Power Pulley Sets release 10 horsepower @ 6900 RPM
and 8 lb/ft of torque @ 5500 RPM (measured to the wheels!).
Always made using only virgin billet aluminum, a handsome
anodized finish, and the tightest tolerances; our pulleys are used
on some of the fastest BMWs on the planet.
Our very lightweight design optimizes performance and response
while under-driving components just the right amount for proper
function at all RPMs. Quality is always #1, and you can be sure
these pulleys will fit right and last a lifetime, replacing BMWs
crack prone plastic pulleys.
- Great for street cars, durable enough for the fastest race cars
and years of abuse
- Saves weight and add HP when every bit counts
- Includes new, correct length and labeled, Contitech OE belt for
WP, ALT, P/S
- OEM crank harmonic dampener is maintained for un-failing
reliability in all conditions
- Pulleys are quality made from 6061 T6 Billet Aluminum
- Alternator pulley is sleeved with a black oxide coated alloy
insert to prevent alternator slippage for high HP, high RPM use, a
VAC exclusive design.
