What is the cruise rpm of the Rotax 915is?
Size, Weight and Power. Like all of Rotax’s four-cylinder aircraft engines, the 915 iS relies on impressively small displacement (82 cubic inches) and high RPM—4800 rpm in cruise. Key Takeaways: The Rotax 915iS is a powerful (135-141 HP sustained/max), fuel-injected, turbocharged, and intercooled engine offering significantly enhanced acceleration and climb compared to the 912iS, with variable fuel consumption depending on speed.Size, Weight and Power. Like all of Rotax’s four-cylinder aircraft engines, the 915 iS relies on impressively small displacement (82 cubic inches) and high RPM—4800 rpm in cruise.Rotax has introduced the new 141-hp 915iS engine to meet demand for a more powerful option, featuring a turbocharger, reinforced components, and a redesigned gearbox that maintains consistent power up to 15,000 feet.The Rotax 915 iS engine will provide the best power-to-weight ratio in its class and a full take off power up to at least 15,000 feet (4,750 m) as well as a service ceiling of 23,000 feet and a better fuel efficiency due to the electronic fuel injection system.
What is the difference between a Rotax 914 and 912?
The 912 ULS/S is the high compression 1400cc, 100 HP engine. It’s probably the best selling engine, but it requires min 98 octane to achieve the power without risk of detonation (the only Rotax engine that do).
