We mounted the DC Power 180 Amp HP High Output Alternator onto our engine and were ready to install the new pulleys.
The Raceonly FD RX7 Pulley Kit is a complete solution with beautiful 6061 billet aluminum pulleys for the crank, water pump, alternator, power steering, idler pulley, and includes stainless steel hardware. This pulley kit is designed to eliminate the factory air pump and engineered to underdrive both the alternator and water pump to prevent cavitation.
Raceonly is an Australian Rotary Performance Shop founded in 2007 who are dedicated to provide the rotary community with excellent support and products to improve the reliability and make owning these unique engines much easier. Customer service and reliability are not often used to describe the rotary engine or community, and it is RaceOnly’s mission to change this. Based off of their vast product offering, continual development and release of new products, and the positive experience working with them, I believe they are achieving their goal.
The 110mm Raceonly Crank Pulley is a single piece made from 6061 aluminum and is much lighter than the 110mm OEM 2-piece steel crank pulley. I really like how this main pulley is the same size as OEM whereas most aftermarket billet aluminum crank pulleys are smaller diameter underdrive pulleys that slow down the speed of the rest of the accessories.
The 115mm billet aluminum Raceonly Power Steering Pulley is significantly stronger than the factory composite pulley.
One of my favorite things about the Raceonly pulley kit is the billet aluminum idler pulley. Most pulley kits do not replace the ugly factory idler, and this blue idler pulley that comes with a brand-new bearing pre-installed makes the entire accessory drive system look far more cohesive.

Looks so good! This article told me that my alternator on my Subaru EJ is kind of tired. pushing out high 13s voltage only.
Billy, this build is going to be epic. We all can’t wait to see it on track!
I’m surprised no special crank damper like an ATI or Fluidamper, any particular reason why?
Rotaries don’t require dampers.
Correct, they do not.
The “no name” brand pulley is GReddy. One of the first under drive pulley sets to come out for the FD in the late 90s.
Thank you 🙂
Does the trigger wheel work with the Apexi power fc ecu? Been a while since I’ve worked on the car and have forgotten more than half when I was knee deep into the FD 10+ years ago.
