We were running EFI on 912s several years ago and sold a few kits. More power, slightly lower fuel consumption and slightly lower vibration levels due to more even mixture distribution. The EGT spread closed up considerably with EFI at certain rpms as it was never too even with the carbs.

Rotax was rumored to be working on EFI about 5 years ago so no surprise it is being released now. $6K though- yikes!

That is one good looking engine. Meets most of my wants/requirements. Too bad they screwed around so long. Welcome to the 21st century, Rotax.

Default New Engine Economics

Rotax is claiming 10% better fuel economy with the EFI. Let's see...
2000 hrs TBO x 4 gph x $4/gal mogas = $32,000. 10% gas savings = $3,200. Might break even if inflation and gas prices go wayy up.

Sounds like UL-Power has a competitor now albeit at a higher cost and with the Rotax name. I still wish Van's would offer an option for UL-Power.

I still have to order my engine, so if the 912iS was available at the right price I'd be seriously interested. The question is whether Vans will see a strong enough business case to offer it as an alternative to the 912ULS.

I'm guessing that the price will be up around the cost of the 914ULS, and Vans would need to make some design changes, test it, write up a new set of instructions and make some minor alterations to the POH. Apart from anything else, it's about 13lbs heavier than the 912ULS. That all takes time and development money, and increases their inventory and management costs, therefore I can't see this engine being offered as an option anytime soon.

My guess would be at least 2-3 years from now, if they ever decide do it. I don't think I can wait that long, even if the cost difference was acceptable. Is anyone out there more optimistic?

Default rotax

I put a new carb'ed rotax 912 on my rans s-7 in 1997, flew the heck out of it. Really liked the engine. I paid $7000 for it brand new, delivered to my front door. When I decided to build another a/c I looked at the rotax again, my heart fell when I saw the price for a new one. I investigated and was told it was because of the monetary exchange etc., dah, kah, dah dah. My opinion is they are charging more because there is a good market for it. I don't think they should charge that much. Good engine, very overpriced for me. Wish they would wake up, some fine day someone will come out with another good engine at a reasonable price.

Hi Rob/All, I agree with you Rob. The iS engine will be a long time coming for RV12. Some fairly large re-design required. The added cost...which is already a problem with the Rotax....and the biggest problem...... another 6 kilograms of weight on the nose!!! However I feel the iS will be a better version of an already good engine.
