Details



Introducing the Revo crank pulley, form and function come together and deliver a truly unique performance part for your FA20 engine. The Revo crank pulley is only .81 pounds which is 4.08 pounds lighter then the factory steel crank pulley! A total of 83.4% weight loss means less rotational weight and faster revs, transforming a new acceleration experience.

BETTER DESIGN

Raceseng set out on a mission to shave off as much rotating mass as possible while maintaining superior strength - a task achieved through design alone. They developed a unique spoke design to eliminate as much cross sectional mass as possible.

SHED THE WEIGHT

  • Stock Crank Pulley - 4.886 lbs
  • Revo Crank Pulley - .810 lbs

TOTAL WEIGHT SAVINGS

4.076 lbs. lighter and 83.4% 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.
