The company is producing high performance engines and injection systems for sporting automotive and ultralight aviation. They have been in this business since a large number of years and are proud to introduce a new system, with fully redundant sensors for the conversion of a Rotax aircraft engine.
The flagship aviation engine is the SA-R917Ti which is a converted Rotax Bombardier 914. This conversion increases the power output from 115 hp to a whopping 135 hp! This is done with a fuel injection system, ECU and big bore pistons. The crankshaft and gearbox are not modified and remain original.
On this page we are going to delve into their high performance Rotax conversion and the subsystems EPA provides.
The EPAPOWER SA-RT917Ti is equipped with bigger bore cylinders with the same nikasil treatment as the original. Pistons are special developed for EPA by a leading supplier. An electronic fuel injection system is especially developed by EPAPOWER for this turbo application.
The electronic fuel injection system has the following characteristics:
Below an overview of the power output vs engine RPM/MAP:
| Setting | Engine RPM | Power (hp/kW) | Torque (Nm) | MAP (inHg) | Throttle Pos. (%) |
| Take-Off | 5800 | 135 / 99 | 164 | 40 | 100 |
| Max Cont. | 5500 | 110 / 81 | 141 | 35 | 72 |
| 75% | 5000 | 87 / 64 | 129 | 31 | 52 |
| 65% | 4800 | 78 / 57 | 114 | 29 | 46 |
| 55% | 4300 | 64 / 47 | 104 | 28 | 40 |
The SA-R917Ti engine installation is equipped with a M170 Engine Control Unit from MoTeC, the leading company in engine management systems. Its properties are:
With this ECU you will always have the latest software and features for your SA-R917Ti engine.
