A group of friends and a few engineers I know are seriously considering trying to make / build a homebuilt 2 seater aircraft.Discussing propulsion.
Thing i`m..wanting to get straight,is the engines availible at the moment..well to be honest I find them primative and darnright expensive.
Our idea..surely you could tune a Subaru turbocharged engine (280 BHP stock),remove the emission rubbish,tweak the boost / timing / compression ratio,ECU and have a more reliable and lighter engine at the end of it..is this allowed???The maintenance cost would be peanuts compared to the engines about today,and fuel efficiency should be astonishing.
Do any of you people know if you can modify a car engine,Or do you have to use an "approved" aviation engine??
Just got me thinking thats all.Please let me know what you think/know.
Thankyou
