I'm getting to the point on my RV-9A that I need to start seriously  considering an engine...  My A&P with Lots of experiance (50  yrs+!) tells me that if at all possible, I should consider a 6 banger  and he recomends the IO360 Continental.  Anybody out there done  this?  Thought about it?  Pros, Cons, etc. will be welcome.

Ray:  

   

Here’s some feedback we gave a -10 builder about the possible use of the Conti IO-360 in that airframe.  Hope you find it helpful.  Not saying don’t do it, but just give you some things to consider in making your engine selection.  

   

The TCM IO-360 was originally developed for use in the Cessna Skymaster. TCM later modified the engine for use in several models of the Seneca. The engine runs smooth, but it tends to be a high maintenance engine. Cores are not readily available for o'h due to its limited use in the certified market, and it has lots and lots of parts so it's expensive to o'h (much less buy one new.) It is a bed mount (which most TCM engines are except for the 520/550 C models.) The engine also has a tendency to run hot, but that can be dealt with on an experimental.

Don't listen. Go with what Van's recommends. 

* The -9A doesn't need that much power

* You are going to add a lot of build time trying to fit the bigger engine

* You lose a lot of usable load

* W&B will move forward, which will affect the flight characteristics, especially when flying alone with full fuel

* The -9A doesn't need that much power



Get a good 160hp Lycoming and if you need to get out of short fields or operate at altitude, put a C/S prop on it.

If you go to the io360 engine your CG will be to far forward. The engine is too heavy.

Hi Ray,

  

 Stick with what Van's recommends for the engine.  Lyc. 320.

  

 To smooth it out and optimize performance, use the constant  speed 3 blade MT propeller.

  

 MT Propeller has a new blade design available for the Lyc. 320  engine.  One of my customers was the first to try them out.

  

 We flew our planes to Oshkosh this year.  I could just barely stay  with him in a climb. His 150 hp RV-9A vs. my 180 hp RV-6A.  There wasn't  much difference in cruise speed, either.

  

 Regards,

 Jim Ayers

You appear to be about where I am. 

  

 I looked at all the options. I am going to go with  a Mazda 13B rotary engine. 

  

 Pros: 

 1. It has a history of robustness and resistance to  catastrophic failure. NASA estimated that TBO would be 3000 hrs. Some vendors  say 1500 hrs. No one really knows. One fellow flew his at reduced  power (30 miles if memory serves) to a safe landing after loosing all the  coolant (forgot to tighten a hose clamp - overhaul was ~$500). For me, this  is the primary reason.

 2. It's firewall forward weight is about the same  as the Lycoming O320 that Van recommends. See attached chart (the chart includes  the PSRU but I am not sure what else). 

 3. The p-port version has been dyno tested at 240  hp! 

 4. It is smoother than any 4 or 6 cylinder piston  engine. No reciprocating parts. Much less vibration and shake.

 5. It runs happily on 100LL, 87 octane mogas, and,  with the proper fuel system gas with alcohol in it (Brazil requires 20%  alcohol). Some builders, including Tracy Crook, use mogas almost  exclusively.

 6. Low cost. Initial cost will depend a lot on how  much you use custom accessory parts. Bare reman engine is $2,000 to $3,000  depending on how many new parts are used. My local Mazda dealer quotes $2,000  plus $1,000 core charge (all parts are new or meet Mazda new  specs). Overhaul is typically $500 for parts. If you can find a used engine  you can overhaul it yourself.

  

 Cons:

 1. It uses about 10% more fuel for a given power.  But if you are willing to use mogas, currently more than $1 less  expensive, the fuel cost is actually less.

 2. You will have to educate yourself and make a lot  of component choices. Lots of help on the net, you will not be  alone.

 3. The apex seals are lubed with 2 cycle oil.  Either in the gas or by injection pump. I regard this as a  nuisance. 

 4. It has a reputation for being  exceptionally loud but that seems to be for the unmuffled version. I have  heard audio clips that allow you to hear the wind noise through the canopy using  a proper muffler. One builder says his is the quietest airplane at his airport.  Not sure what that means exactly.

  

 Conclusion: the robustness is worth the extra  effort and fuel. The power to weight is a bonus, particularly if you do mountain  flying at altitudes over 14,000 feet as I do (my home airport is at 8,000 feet).  Just don't exceed Vne.

If you do go the O-320 route (or Lycoming 360), give some 

serious thought to going injected ... Bart at Aerosport will 

put together an IO-320 for you.  There's lots of advantages to 

injection over a carb .... check out Dan C's project 

documentation at http://www.rvproject.com - his reasoning and 

general installation is very well documented.



And a "been there, done that" comment - anything you do that 

diverts from the plans will cost you time - lottsa, lottsa 

time.  If I look at my experience I would say 5-10 times as much 

time per custom item.

Folks may want to consider the new ECI 340 "Stroker" engine for the -9.  I am, considering the high DA enviornment I live in, in Southern Arizona.  The engine seems like a lot of bang for the buck.  As a side note, a Van's engineer had previously told me there would be no harm in using a Lycoming 360 in a -9, providing limits were not exceeded, as the 360 only weighs about 8 lbs more that a 320.

Surprising any Van's engineer told you that.  The issue - this has come

up many times on various forums - is vibration.  A 360 vibrates more and

there have been cases of -9 empennage cracks in a matter of a couple

hundred hours.  It's not a good idea.

You make a good point, but it's true, they did.  But this is why I am now looking at the ECI 340, lighter, more power, and hopefully smoother than a 360.  Glenn.

Then again, my own RV-9A with a 165hp Eggenfellner Subaru balanced out at

0.02ips.  Try to achieve that level of smoothness with ANY lyco!  The 6 cyl

212hp is even smoother and weighs no more than an IO360.   Myths abound...

To dispell any myths about your Subie Install...how about sharing:



The finished weight of your RV9A,

Typical Fuel Burns/RPM's/MP's

Typical Speed's (TAS's).



Not meant as a flame at all, but just for an apples to apples comparision.

I'm sure many people would like to see your real world number to assist them

in making their decision when thinking about an alternative engine.



Also, just a quick side but if you were to bolt your prop directly to the

crank of your EGG and run it a prop RPM (vs. 3,4 or 5K RPM) then you'd see

IPS number closer in line with Lyco, conversely if we put a re-drive on a

Lyco it would go way down to.  Again, not meant as a point of argument, just

trying to make sure people have all the information as to quash any myths!

I for one have nothing against Sube's or other alternative engines.  It just

always seems that there are only two sides to this argument....love 'em or

hate 'em, and it really shouldn't be that way.  Objectivity would go a long

way - instead of subjectivity.



Cheers,

Stein.

Not true at all.  The Subaru has 7 main bearings on an 18" crankshaft and

has no significant counterweights because of its symmetrical design.  It is

extraordinarily well balanced.  Also fact, our redrive contributes more

vibration (not the other way around as you suggest).  It has a floating

as a conventional aircraft engine, we have achieved a very low level of

value of quiet...

And by the way, for the hot-rodders out there, one of our customers flew

A 2 blade propeller has a second order harmonic that isn't present with a 3  blade propeller.

  

 For smoothness, get a 3 blade propeller.  There are a number of  different ones available.  One would be the fixed pitch 3 blade Catto  prop.

  

 It also follows that if you really want smoothness, get a 4 blade  propeller.  This eliminates the third order harmonics of a 3 blade  propeller.

 Jim Ayers

Lycoming IO-360-L2A including all the accessories and exhaust.

This engine is rated at 160 hp by 2400 rpm, according the Lycoming booklet.



Any thoughts, besides the important 8 lbs more weight?

Folks may want to consider the new ECI 340 "Stroker" engine for the -9.  I

am, considering the high DA enviornment I live in, in Southern Arizona.  The

engine seems like a lot of bang for the buck.  As a side note, a Van's

engineer had previously told me there would be no harm in using a Lycoming

360 in a -9, providing limits were not exceeded, as the 360 only weighs

about 8 lbs more that a 320.  Glenn Brasch, Tucson, -9a finish kit.

 Yep.  I'm sure I could have put her (and me ;^) on a diet if I wanted to,

but I like my creature comforts and gadgetry.  Not everyone builds for the

same reason.  A lot of my own extra heft is from non-essential

instrumentation (like a full primary six in addition to the EFIS plus AP

plus DVD plus CD plus...) and lots of paint, wood, and upholstery.  The

amount I contribute to a liquid cooled engine is about 45lbs which seems to

coincide with what other like-minded builders report.  Still, I wouldn't

change a thing (maybe less primer).
