Hope this doesn't start an  'engine war', but I'm curious if anyone has installed (or plans to install) a  300-HP Lycoming that has the same physical characteristics (dimensions, inlet  design, and weight) as the 260-HP version Van's recommends?

  

 I know the Glasair-III guys  use the IO-540-K1A5/K1A5Ds with lots of success.  Just wondering if the  RV-10 would be a suitable candidate for a 300-HP injected Lycoming.  And  yes, I am aware of the manufactuer's opinion on engine recommendations....  .  I'm just doing my research before I take the plunge and start an RV-10  project.

  

 If you don't care to  possibly be flammed or publically share your info, please email me  direct.

  

 TIA,

Jack, this question will be best answered by Rhonda and the group from Barrett.  The cowl design was specifically directed and design to be made so narrow that the wide deck Lycoming and Continentals could not fit.  You added weight and inlet design into your criteria which would eliminate use of a forward facing (rather than updraft) injection unit.  I believe that only allows compression ratio increase and tuned headers as the means to your end.  The same weight requirement eliminates a turbo.  Hopefully Rhonda will restate how much hp can be squeezed with a clear trade off from “the same physical characteristics (dimensions, inlet design, and weight) as the 260-HP”.  I think I remember 290 (dynode) but with significant fuel type restrictions, consumption rate and oil temp issues.  The James Wholly Cowl may change some of this.  Again ask Ed Hayden.  You can always use Hollywood Horsepower and tell everyone 325.  

   

Modify your parameters and then ask Vic Syracuse and Ed about the output of their fire breathing red powerplants.

I know of one -10 builder who had BPE build his engine, with a bigger 

fuel injection pump. 9:1 pistons, Cold Air induction, and Forsling 

exhaust. It dyno'd at or above 290 hp. That's the same config that I'm 

also in line for from BPE, I'm hoping for similar results (depending on 

the weather/temp the day they run the engine). Bigger pistons would 

easily push the engine to or above 300 hp. I believe that Vic Syracuse 

has 300 ponies on a Lycoming based engine in his plane.

Vic Syracuse has a 310hp engine. From what I  understand has been no problem in the RV-10.

The mount & cowl supplied with the RV-10 will accept parallel valve Lycomings (either narrow or wide deck).  What won't work is an angle valve engine like the IO-540-K series mentioned.  The engines mentioned that are in RV-10s and achieving greater than 260 HP are all parallel valve models with various mods - higher compression pistons, cold air induction, etc.

Is that me?  Sounds like me but I dyno'd at 272 I believe.  I am also

running dual LSE III ignitions so you could probably expect to see a

little more HP off of mags.  It was also over 100 degrees when they ran

the dyno test which I'm sure ate up several HP.

I was Gary Foster's engine.
