OA3150 RC 2.3 THE supercharger for Top Fuel bikes for many years, this is the unit that is fitted to the quickest and fastest dragbikes on the planet.

HPS 2.1 RC The very latest in the line of superchargers for dragbike applications, the HPSRC is 40% more volumetrically efficient than the OA3150 so ideally suited to lower revving twins whilst in a smaller package.

KR Carbon Fiber Injector Hat is designed to fit the current state of the art OA3150 2.3 RC Supercharger. The injector features many advantages over the current models available on the market:

• 675 grams in weight, less than half of the current aluminum alternatives
• Optimised air flow design
• Needle roller butterfly shaft bearings
• Minimised WOT travel (9.5 degree closed angle)


Pro Mag 44
The Pro Mag 44 is the mother of all magnetos. With no magnets to recharge, no points to replace and by producing an amazing 44 amps of primary current, it’s no wonder that the Pro Mag 44 is the choice of the leading Top Fuel Bike, and Top Fuel car teams.

The Harley Nitro Ignition is the most advanced ignition system out on the market. The FDP Programmable Harley–Nitro Ignition system combines the benefits of a Capacitive Discharge Ignition with the best features of an Inductive Ignition. The result is an incredible 800 millijoules of spark energy for 400 micro-seconds. A combination of two ignition control units are used, the main unit houses the CD and Programming controls and another with the inductive circuitry.

When the two controls are triggered they send their unique power characteristics to the two Hybrid Coils. These coils must be used with the Harley-Nitro Ignition and combine the two sparks to work as one. The CD side is primarily responsible for ionizing the spark plug gap while the current from both coils produce a high level of current and sustained spark.
