Hurley 13B Injection and Turbo Rotary Engines

All 13B injection engines are built with a new improved tip seal, designed by HME (now supplied to most UK engine builders and exported world-wide) which eliminates engine seizure caused by tip seal roll-over or wedging of the original two tier design. This improvement alone will extend engine life by at least 30%.

The RX-777 conversion gives 160 mph performance combined with an economical 24 MPG at 70/80 mph motorway cruising.

Tripple Carburettor

After ten years of development HME are now proud to offer our multi-rotor engine conversions, the first triple engine was built three years ago and has been tested by many magazines in the United Kingdom, Europe and Australia, all of which have been impressed with the performance and fuel economy. To date 25 engines have been built for road and racing.

The turbine smooth and refined performance of the triple rotor cannot be compared with a ported and tuned twin rotor giving the same max. power output.
For example the acceleration time from 40-60 MPH in fifth gear is only 6.5 seconds as compared to the standard time of 10.5 seconds = 40% faster, and a 0-60 in a little over 5 seconds while still returning 25 MPG+ motorway driving, and an added bonus of the triple rotor is the truly magnificent exhaust note. The engine has excellent low speed torque which makes it very easy town driving.

The total weight of the Triple Engine is 315 lbs. together with carburettor and exhaust system, is in fact 15 lbs. lighter that the standard RX-7 engine, with carburettor and exhaust system and is only 4 3/4" (120mm) longer.
