Looking for a powerful, reliable, 1000 hr TBO, fuel efficient (2 gph),
4 stroke engine for your Flightstar, Challenger, Rans S14, SkyRaider, or
Kolb?
It appears that Raven ReDrive Inc. out of Boulder Colorado may have
just what your looking for. Raven Re-Drive as taken their, 3 cylinder
vertical Suzuki conversion, laid it down sideways, dry sumped it like the
912 Rotax, and designed an intake manifold which uses an altitude
compensation Bing carb. For those concerned about carb icing a Metro Geo
factory preheated manifold system is standard.
In this configuration the engine package with alternator and starter
comes in at 112 lbs and puts out 58 horsepower. The unit uses a 2.33 to 1
belt reduction drive, cruises at 4200 rpm, on just over 2 gallons of fuel
per hour and peaks out at 58 hp at 5700 rpm. According to the factory
"this combination will spin a 3 blade 68 inch IVO prop with 10
degrees of pitch and put out 325 ft. lbs. of thrust."
"This has proven on gyro's and two place trainers to give a fuel
burn of 2.5 gallons per hour, and as low as 1.3 gallons per hour on units
such as trikes." Raven Re-Drive has also designed a twin rad kit
and mount using recycled Metro Geo heater cores, that can work in both
tractor and pusher applications. In addition they offer an optional
exhaust with customer header that comes in at just over 3 lbs. While
the factory is quoting TBO times of 1,000 hours they are quick to point
out that "our engines are designed to cruise at 4,000 rpm, which is
exactly where the car engine would be operated at" "the Metro
Geo engine has can easily go 150,000 miles in a car application - at 50
mph that would be 3,000 hours!"
