Webber 750 engine

[scottessex]

I want one real bad, I wonder how much they cost.
I also wonder how much had to be changed from the snowmobile application.

[PalmPilot]

You can get turbo (bare) long blocks starting at about $4500. But then you'll have to add intake, exhaust/turbo, intercooler, sensors, ecu, radiator, etc... So it's probably more cost affective to pickup a used machine.

Better off with the complete sled and selling what is not going in the air.

Not much needing changed to get one in the air and the actic cat t660 looks just as EZ. the raven redrive guy said he had 2 cats to sell. I was going to call me but here it is weeks later.

[WHY]

This looks like a real gut ache for Rotax, but then if you look at the title of the engine it is "MPE" (multi-purpose engine) so it had multi use as a design feature and this is what is making it so "usable" especially in our "aviation" use. looks like they have done a nice job on producing a custom gear box for it as well. Wish them the best of luck on sales growth and production in the market place. They might eventually get some govt contracts for "drone engines" and make some other "big" name manufacture a little nervous.

Now all we need is "proof of performance and durability" and the race is on.

The proof is already here, beyond the ski's & sled's. Out here in the western states it's the latest rage in the offroad UTV & Buggy scene! These guys are doing the swap's & pumping up to 170hp out of the turbo motors. And you wouldn't believe how much they abuse them, from the desert to the dunes. I met one person that had the intake boots crack from running it hard & jumping all day. He wasn't aware until that evening, took it home & cleaned out the dirt residue up to the pistons, then changed the oil. That was at 800 miles, he now has about 2600!

Thanks, GaryMac

GaryMac,

Sorry for taking so long to answer your question but I lost track of this thread and hadn't checked it for a while. Anyway, I just saw your post.

I do not think you will ever see this engine on a Monarch Gyro. This is a bigger and heavier engine and would replace the Rotax 912 that the Aurora Butterfly was designed for. The Monarch is a lighter Gyro designed for smaller engines and less power.

I do not know how soon you will see one of these available on a Butterfly but I suspect it will be a while before it comes to market. Larry is more interested in the newer 850 version than he is the 750. It may be a while before he has access to the one he wants to use and then it will take some time to develop but it is in the planning stages and I believe will be a great option when it finally becomes available.

Hey PalmPilot

Thanks for that input , looks like the RACE IS ON !!!!!!!!!!

I don't think it will be bigger and heavier engine than 912 and it will have the power of the 914.

This is what I got from the guy selling it. affter VAT and shipping they want as much as the rotax well almost.

I think it can be done at home for under 9000 usd

they have a very nice gear box for a front mounted engine but for a pusher bolt a cbox on it and go.

t his will work.

Here is a deal If someone wants a good set up this is the offroad package weber wants about 7000 as it is here. I know this guy said it is 160hp but I know it is a 120hp it is the same engine hoverpod use.

This is exactly the kind of talk that drives me crazy. The only way to verify that it will run a propeller for may hours reliably is to use it in an aircraft. If you could verify aircraft engine reliability by running it in a totally different application, then I guess we could say that there are literally hunderds of reliable aircraft engines out there in cars, snowmobiles, off road vehicles, generators, pumps, motorcycles, boats and watercraft. How many engines have we seen come and go over the years? There is a reason we do not have a couple hunderd proven engines to choose from for our airplanes. Is it because all of the people who have tried are stupid? I dont think so, I think that spinning a propeller in an aircraft is a very demanding application and ground based "testing" cannot be applied.

What really gets me, is the people that "seem" to have a stick up their aft, and "appear" to portray themselves as self proclaimed experts! Yet, "seem" to enjoy bashing others for there experience, or lack of... Such as you did with fiveboy! Yet also, do not "appear" to have the intelligence to decipher between a serious or lighthearted post!!!

Whats up with that Dude!!!

We are all here to learn from each other and to promote a safer and more enjoyable sport!

Now I'm no expert!!! And do agree with some of your statement...But with regards to engines, isn't this why it's "apparently" called experimental!
Were all looking for the "best of the best," with the correct power to weight ratio... Hence, not hundred's to choose from... And obviously would have to be the one's that are proving themselves on the ground first...
