Can anybody refreash my memory on this. A brave chap was trying to get the Rover V8 (lovely engine) certified for aircraft usage. This was 10 or more years ago.
The original installation was a direct drive setup so that the V8 was only producing around 110-120 hp at 2,800 or so rpm instead of its more normal 160 hp at 4,500 (approximate figures dulled by time
). He had plans to fit a belt drive reduction unit in the future but initially was concentrating on getting the engine approved.
The test pilot in Pilot ( the only mag available then) likened the modified Chipmunk to a mini-Spitfire.
The project seems to have faded into the past like the Phillips Speedtwin which is extremely unfortunate.
