I'm not as brave as others and intend to conform to the prototype, but +$40K for an engine for a 2-seat experimental aircraft doesn't go down easy. I'm hoping that by the time I'm ready to purchase the engine Van's will have worked out a deal with Lycoming given the positive response to the RV-14 introduction.

Lycoming is already selling the IO-390 for less than the angle valve IO-360. My new IO-390 arrived from Lycoming a few weeks ago. I ordered it through Vans during the Oshkosh show when they were offering a discounted price of $33,500. Still not cheap but it's new and its proven, and parts are available if you should need them.

You could always buy a used angle valve engine from a Mooney, Arrow, Seirra...

The ECI engines are really nice, but when you look at all the facts such as compression ratios vs HP output and price then the Lycoming starts to look better. The R series cylinders may be the way to go if you go with a parallel valve engine and money is not an issue.

UL520is
 
I am in the final hours of my phase 1 testing on a non RV aircraft. I have the UL Power UL390is (160hp) and I am so impressed with the it I will likely never install anything else in my future builds.
If you need a 200hp, full fuel injected, fadec, electronic ignition, 100 lighter than the io360, runs on mo-gas with up to 15% ethanol (if desired) then check it out. The UL Power team will work with you to design you FWF kit (mount). I know they are currently puting it on an RV 4 and will be flying it soon.

Turbine RV-10 featured in Kitplanes this month
 
I was just reading up on the turbine engined RV-10 about an hour ago, then got an email from Kitplanes, indicating the plane was featured in their issue this month: http://www.kitplanes.com/issues/32_6...0_21268-1.html

Aerosport Power IO-382 'Wildcat'
 
I noticed on Aerosport Power's post about the 382 that they listed it as being suitable for the -14 so I asked them about weight, since it's a parallel valve engine. Here's the response from Gerard Poitras (posted with his permission):
"You are correct that the IO-382 is a stroked parallel valve 360 engine. It basically uses a Superior 400 crank in a 360 roller cam engine but needs slightly larger cylinders than the normal parallel valve 360.

The dimensions are slightly smaller than the 390 engine. The 382 dimensions are: 19.7? high x 33.7 inch wide x 32.7 inches deep (long). The weight of the 382 engine is 302 lbs (due to the counter weighted crankshaft) compared to the weight of the 390 Lycoming 308lbs. The horse power of the 382 is 202 HP as compared to the 210 HP for the 390 engine. This 382 engine also has a cold air sump as standard equipment.

The trump card is that the IO-382 is $33,500.00 USD base price (with Slick Mags). This price is $2,000.00 less expensive than Van?s best price on the Lycoming 390 (Van?s ?Sun N?Fun? sale price was $35,500). We also offer engine and prop bundle pricing ($1,000.00 off the price of the engine when bundled with a Whirlwind prop).

Bottom line is that you will not have to attach lead to your firewall but you will be able to put some of the saving either to your cockpit or back into your pocket."
I wonder where the W&B would come out on a -14 if you used an engine a bit lighter than the 390 and also a lighter composite prop. Hopefully Vans has designed it so that the 390/Hartzell combo puts you near the forward end of the CG range. Scott do you know?

Thanks,

Is there any way to get a look at the weight and balance data from Van's prototype 14? It would sure help out in our planning for our builds and answer some of these questions.

Continental 6?
 
I wonder if the Continental IO-360 would be a good fit as an alternate engine with equivalent power. From my very cursory searches, it is a around 12 pounds lighter than the -390. At one point, the RV-10 was going to have an IO-360 option. I have no idea how much it costs to buy a core and overhaul one, but it might be worth looking into.

6 cylinders, I'd presume:

- the size of the engine probably not quite right when compared to the 390 ... would it be longer? All that tubing on top could also be a problem ... might have fun fitting that cowl ...
- that 6 cylinders cost a bunch more to overhaul.

Pretty common engine in general ... could be an interesting avenue to investigate ...

There's also the -AF for those worried about 100LL availability, though only 180 HP ...

Oh, and not so good TBOs it seems, only 2 models have 2000 hours?

I haven't seen specifics for the Continental -360, but I do know that IO-520s and such are a bit cheaper than the Lycoming counterparts.
