Default Engine Selection Question

I am to the point in my RV-14A QB that I need to start thinking about which engine to use. I've pretty much narrowed it down to the Non-Certified Lycoming IO-360 200HP and the IO-390 210HP. Both engines will probably serve me well, but am I asking for additional expenses with the IO-390, such as alternator, electric fuel pump and other accessories? I know the 360 has been around a long time and supposedly most of the kinks have been worked out. Is the additional 10 hp you get from the 390 really worth the effort and expense?


On another matter, I do not find a Firewall Forward Kit shown on the Van's website. Do I need to call Van's for FWF selection guidance?

Joe---most of the FWF kits we've done for builders were for the Thunderbolt IO390, with the AFP FM150 servo. Several have opted for Pmags, both single and dual, and a few have opted to have the B&C backup alternator installed.
Only slight differences in hoses.

Not sure I understand. You will have the same accessory expenses with both engines.

Some thoughts:
- I flew an RV-14A with the IO-390. My take was the plane needs those extra 10hp.
- The Van’s RV-14/14A FWF kit is specific to the IO-390 with the standard injection system. AirFlow performance will work but requires some mods to the FWF kit (not hard, but required).
- The Thunderbolt IO-390 engine with a pMag is a good deal. I got a new IO360M1B from them with one PMag and the other mag hole empty. It now has a second pMag mounted.

Default Either works

Joe, I haven’t flown an “A”, but i have flown the factory RV-14 with the 200hp io360; and i’ve been flying my RV-14 with the stock IO-390 210hp. They’re both awesome, but there is no “additional trouble” fitting the 390, and I love it. As for the firewall forward kit, they definitely have it and sell it; I just ordered it when I ordered my prop and engine from Vans. I went with a B&C alternator but otherwise their ffw kit with no regrets.

Joe - I think I was the first person other than factory pilots to fly both the 14A and the -14, and gave both of them a good workout. Realistically, it was hard to tell the difference between the one with the 390 and the one with the 360 - its a great airplane either way!

Just my experience.

As I understand it, 14/14A were designed with the IO-390 in mind, and the plans/parts pretty much revolve around that design. Prices aren't hugely different. While the IO-390 is a newer design than the IO-360, it's now (in "certified" version) being used in production aircraft - STC for some Mooneys and Cessna Cardinal, and now is the standard engine for Cirrus SR-20.

All that said, the IO-360 has a very good reputation and there are a lot of them around.

It's a chocolate vs vanilla kind of problem..

The data is creeping in...the angle valve 390 doesn't need or want a whole lot of ignition advance. The 390 is also a higher CR, 8.9/1, so less detonation margin. If you insist on using a p-mag (rather than an EI with a user-drawn advance map), be sure to install the retard jumper.

Dan, is there somewhere I can read more on this? Dual P-Mag on an IO-390 here.

Found the RV-14A Firewall Forward Kit on Van's. Thanks for the lead. However I did not see a listing of included equipment/accessories. I am confused about what additional things I will need, if any, to obtain in order to make my engine installation "complete".
