Question for those 9 builders who went with (I)O-360 engines.

A pretty good on an IO-360 may come my way. I've already ordered my finish kit based on an IO-320-D1A through Vans.

Will the standard engine mount and cowl work, or will I need to swap these out?
 
Nate - if this comes through for you, please keep me updated, as I'm not far behind you in the build process and I intend to run an IO360. I'd be interested in any changes you need to make.
 
I am doing the same thing

I got the finish kit for a IO320, but am going to go with the IO-360 also, probably from mattituck. The finish kit contained the cowling for a 6, so I am thinking it should be ok. Please post when you find out for sure. Of course, we could just ask Vans.....
 
I had considered this option before buying an engine but, heard stories about pulse cracks in the tail area from the larger engine. Not sure if there was any truth to it but went with the 0320 160 HP. One less thing to worry about. B.T.W. Have been getting some time in a 9A with a 0320 150 HP engine and it's no slouch!

Thanks Earl! :D

I was told by one of the Vans guys to make sure I ordered a 360 cowl for my planned IO-320. He said the 360 cowl had room on the bottom for the injection servo and hdwe, while a standard 320 cowl would not.
 
As what Terry said, be sure you order the cowl for the 360 (which is not standard on the 9s). I had zero issues with the engine fitting into the space since the cowl is used on the 7s and 6s with this engine.

FWIW, I just returned from a trip with about 15 total hours flying time and ended up running just under 6 gph on average, cruising at about 165 mph. That 6 gph includes taxi time etc. VERY happy with this performance.

Nate,

My finish kit lists WD-739-PC as the engine mount and that worked. I would check with Vans when ordering (I did a quick look at their website and don't see an engine mount listed as "parts"). I believe that the difference between the 320 and 360 is basically the length of the cylinders and not the crankcase etc., so probably the mount would work with either engine.

This was the firewall forward kit I was recommended by vans for IO-360 vertical induction. I would recommend not ordering the control cables and not drilling the control cable firewall penetrations until the engine is hung.

I had no installation issues...

I built an O-360 for my 9A. @ 143kts gs, I'm averaging 7.2 gph. I had no installation issues and followed the guidelines mentioned in an earlier post.

Make sure you discuss the choice with Vetterman before you order.

My reason? We have access to ethanol free auto gas and given the lower octane, I installed 7.2 compression pistons which, according to Superior, delivers 168-172 hp. The O-360 is heavier than the O-320, but if you install a fp prop instead of a cs prop, the difference almost disappears.

Aside from the inherent difficulty of slowing down an airplane with a prop pitched for cruise, climb is generally 1550fpm at 3500 d/a with a full load of fuel and my skinny wife.
 
If you wanted to install a heavy prop like a Hartzell with the 0-360 you might want to think about allowing for possible modifications that will move the C of G back, such as installing the battery further aft. My 9A with an 0-320 and a Hartzell with me, full fuel and no baggage has the C of G at 6% (of the allowable C of G range) aft of the fwd limit. The plane flys OK at this C of G however the weight on the nose wheel of 342 lb is over Vans recommendation and I would need to have some weight in the baggage compartment. I suspect a heavier engine and prop could be a problem unless the C of G is somehow moved aft. I stand to be corrected , but I can recall something about the 0-360 mount being shorter which would help move the C of G aft. :confused:

My original CG with a pretty much standard installation, Sensenich FP prop was forward. I was within limits on most of the calculations, but with full fuel and my wife flying (110 lbs), it was forward of the design CG. I ended up moving the battery behind the baggage bulkhead and putting my ELT in the tail and am ok. My nosewheel weight initially was 313 lbs and is now around 290.
