Details



Lighter then stock and just as strong. Raceseng billet aluminum pulleys for the Scion FR-S and Subaru BRZ are tested on the road and track; taking them through every conceivable rpm range and torque differentiation. The Revo crank, water pump and alternator pulleys shave 4.73 lbs. or 75.1% of rotating mass from the stock engine pulleys. This reduction in rotational inertia will give your FR-S/BRZ quicker acceleration throughout the RPM band, improved throttle response, as well as delivering horsepower and torque sooner to your wheels. All Revo pulleys are non-underdriven, meaning they are the same diameter as the stock pulley. This allows you to use your original pulley belt and prevents driving issues seen with underdriven pulleys.

BETTER DESIGN

The Revo pulley kit S1 shaves 4.73 lbs. of rotating mass from the stock crank, water and alternator engine pulleys! A total of 75.1% weight loss means less rotational weight and faster revs, transforming a new acceleration experience.

SHED THE WEIGHT

  • Stock Crank Pulley - 4.886 lbs
  • Revo Crank Pulley - .810 lbs
  • Stock Water Pump Pulley - .990 lbs
  • Revo Water Pump Pulley - .565 lbs
  • Stock Alternator Pulley - .421 lbs
  • Revo Alternator Pulley - .192 lb

TOTAL WEIGHT SAVINGS

4.73 lbs. lighter and 75.1% reduction in rotating mass

BETTER MATERIAL

They specifically chose an aircraft grade 6061 T6 aluminum because of its tensile strength and use U.S.A. milled aluminum only.

BETTER PROCESS

The Revo crank pulley is precisely crafted using state of the art cnc milling and turning centers. The manufacturing is done in house because we can accurately and consistently control our product.

 

DOWN TO THE FINISH

Raceseng has meticulously refined how their parts are anodized to insure the best anti-corrosive and tarnishing properties. The brilliance of our black, clear and red finishes can be seen and will be easy to maintain. Their Apex R is post machined, not laser engraved or pad printed, because it's what they do best.
 

CAN I REPLACE THE CRANK PULLEY HARMONIC BALANCER?

The harmonic balancer has the sole responsibility to retard or lessen the resonant frequencies that occur during the normal operation of any internal combustion motor. The crank is like a tuning fork for musicians; when the firing cycle hits each cylinder, its like a flick to the tuning fork. So when you see the term "harmonic", it is a literal description of what is occurring to your crank. Your crank is actually flexible, believe it or not, if it wasn't, your engine wouldn't last more then 10,000 miles. It flexes on a microscopic level to absorb the explosion from each cylinder, this flex is precisely what creates an engine's natural frequency. Some vehicle's frequencies are more violent then others due to the architectural layout of the cylinders. For example, a V6 or V8 will have higher resonance because the downward thrust of each cylinder travels through the center-line of the crank in a non-linear pattern; this actually has the ability to amplify the frequency, depending on your RPM. Compare this to an I6 or I4 and you reduce the harmonics due to the linear pulse of the cylinders approach the crank from a single direction. Finally the Flat-4, with force traveling through the crank to opposing cylinders, the frequency is reduced by its own operation. We're not saying that the frequency is completely eliminated! We're saying that of all the engine formats available, a flat-4 is the best candidate for a lightened crank pulley.
