Horse Power
Hi again,
I forgot the other question I had, is there any type of way to increase the hp from 210 hp short of Turboing the engines. I love the plane so much, but do wish it had a little more power. I do know about the Rocket convertion, but thats to costly. Mark |
There was an article in September 2005 Aviation Consumer. It covered the topic of porting & polishing. This is a process of cleaning up obstructions & roughness in the intake and exhaust ports. They also discussed the benefits of grinding the valve seats. The bottom line of the story was that you could gain up to 4 HP per cylinder, or in other words, 24 HP in a six cylinder engine.
The shop discussed in the article was Performance Engines, based at Brackett Field in La Verne CA (southern most end of California). Their website is: http://www.performanceengines.com/ You should read the Aviation Consumer article. They address the very gray area as to the legality of this mod. It’s available online to subscribers at: http://www.aviation-consumer.com |

Well,
It was not in a skymaster but I have heard of several cases where this type of thing was done to an engine with less than positive results. If done improperly you could trash the cylinder(s). |
Owen Bell also has some engine mods for the skymaster. I think they are similar to the Riley conversions, but are more affordable. His company is "Aviation Enterprises" I believe.

Air Filters
I also recently heard of significant HP increase by changing from the Brackett air filter to the K&M (I think that is the brand - regardless, it's something like that which you will find in TAP) air filter that is STCd for our birds. I know of one IA who swears by them as a fast and cheap way to increase HP.
