Hello Fellow Experimenters

We are completing development on a new piston engine product line for aircraft up to 350 HP for experimental aircraft. The engine uses an aluminum V8 marine engine foundation, modified for the aircraft mission. The engine is controlled by a redundant electronic fuel injection system and other engineered components to meet FAA part 33 and 23 standards. The engine controller is software controlled and can be quickly programmed to meet optimum performance for multiple aircraft types, weights, and prop designs. We use a blank GM Delphi ECM we source directly that is without any automotive programming; we developed our own aircraft mission specific calibration files using the same engineering firms GM uses. Additionally, the engine controller can wirelessly connect to our service app that not only allows quick and precise troubleshooting and tuning, but can be connected by WIFI for remote tuning and escalated diagnosis by our technicians if needed.

The engine is matched to a PSRU (optional) with several different gear ratios available. It is clutch-less, low maintenance and has chip detector monitored by the ECM. Each engine, PSRU and prop combo is tested by vibration analysis and by finite element analysis for structural requirements to part 23 standards. A digital engine display can be customized to display over 50 engine parameters, even fuel consumed or fuel levels. Additionally, the display monitors over 75 parameters and will annunciate an alert when any programmed levels are exceeded. Each alert indicates description of issue and specific trouble code until acknowledged by pilot. Each fault remains in the maintenance page with further info such as time stamp and specific service manual reference and troubleshooting tree.

The engine is flex fuel rated, so can consume several gasoline types, including AVGAS. Real flight performance numbers indicate it is more than 20% efficient (fuel flow vs. TAS), and cost 60% less to operate than O-360 legacy engines. Our C172 test aircraft operates for less than $19/hr compared to over $60/hr with original engine, while still far exceeding stock performance.

We would like to seek some input from the experimental community on what features are most important for such an experimental crate engine product, and gauge level of interest within the experimental market. We realize most auto conversions are home -grown, and many have negative perceptions of them for a number of reasons, so looking forward to gauging how many experimenters may see value in a more developed conversion and their suggestions of what features, capabilities and price point it should have.

Covid has left us about 4 months behind on C172 and C182 flight testing program, but anticipate product will be launched by next summer, and experimental crate engine soon after. Additional info can be found on www.corsairpower.com

I will monitor this thread regularly and look forward to hearing your thoughts/advice/ and ideas.

Thanks for any input. Fly safe.
