Hi Guys,   

    

   

    

My neighbor is selling his brand new (still in crate) Monty Barret built experimental IO-540-X (A1A5).ser# 8686 It has all the paperwork, dyno data and all accessories except the prop governor. $30K. $28K minus the accessories. It's a great deal, if you haven't checked new IO-540 prices lately, especially a Barrett engine. I'd buy it if I could...

Not so fast, it all depends…  If it started out life as an O-540-A1A5 then it’s a parallel valve engine (originally rated at 250HP (at) 2575) and a good match for an RV-10.  If it started out as an IO-540-A1A5 then it’s an angle valve engine (originally rated at 290HP (at) 2575 RPM) and won’t physically fit on an RV-10.  

   

Note that Barrett lists 2 variants of the IO-540-X on their web site that are VERY different: the “Light Weight IO-540-X” is based on a parallel valve engine, the “Heavy Hitter IO-540-X” is based on an angle valve engine.    

   

It would be easy to identify what this is either by looking at the valve covers or calling Barrett, but based on the information posted so far, there’s no way to tell.

It *is* an angle valve.. as I understand, not the best fit for a -10...

They already posted that it is an “angle head” engine.  I suppose they meant (or it means the same thing as) “angle valve”.  

   

Do not archive.

Bob, the grammatically correct answer is it might not fit in the currently constricting factory offered RV-10 cowl.  The mods to a Wholly Cowl or another variant might just allow such a unit. Weight is far more important than fitting a cowl which several builders have already exchanged for an improved version.  Has anyone asked the James Group?  Michael.. do you know the answer?  

   

Barrett has confirmed what it is as an engine.  

   

The deal merits an in-depth discussion, so builders better understand the opportunities and limitations.  To my knowledge, only the factory constricted cowl is currently in use.  Vic and Ed are/have installed modified stock dimensioned engines.  Builders are still in the queue for the new variant cowl.

Does anyone know how Barrett manages to save so  much weight on the lightweight engine.  They claim about 60 lbs less than  the "normal" IO-540.  Does this make sense for -10 builders.   

  

 OK, dumb question from a new builder.....   does this mean I have 60lbs more usueful load (yes, W&B will change I  know).

Every pound saved is a pound of useful load gained without playing funny games by artificially increasing gross weight (on paper) over VANS recommendations.  A pound saved forward is a fractional pound saved aft to keep the CG at the same performance point.  This is the reason the MT three blade composite held so much interest in this project. An additional pound added up front is often counter-balanced with a leveraged lesser weight (way back) aft.  Hence the reason Boeing 747s used gold counterweights in the tail and why I have jokingly posted about depleted Uranium counterweights back in the tail of the RV-10.
