4 Rotor Engines


Our  next revised specification 4 rotor race engine is becoming closer to completion, the three piece eccentric shafts with their matching counterweights are all  finished and currently undergoing balancing. We have now decided to manufacture the complete engine block from aluminium which massively  reduces the engine weight and giving an excellent power to weight  ratio. Along with this we have manufactured our own bell housings to suit the custom  triple plate clutch and flywheel assembly. This is also a direct fitment to a Hollinger 6 speed or the new Modena 6 speed sequential gearbox. All going well we should see it on the dyno during February. Be sure to check back here for further updates!

4 Rotor Engine

The new Xtreme Rotaries 4 Rotor race engine package is currently undertaking our vigorous testing and development program. The current engine is a naturally aspirated peripheral port configuration. It features billet aluminium 2 piece cermet coated centre plates with full stationary gear support and redesigned cooling system. This engine also incorporates a fully engineered dry sump system and a billet shortened front cover with bearing support. All counterweights, stationary gears and 3 piece eccentric shaft have been totally re-manufactured. The Xtreme Rotaries 4 rotor engine is only 110mm longer that a 20B and is approximately 7kg lighter. Through initial testing on 98RON pump fuel it has made 650 plus HP. This engine will be available early 2012 and any genuine interested parties can fill out the contact form below.
