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!"
