REFLECTOR: Air Filters on IO-550N

[Brooke Wolf]

Very interesting Craig.  It looks like a rather elegant design.  Can I assume that your filters are in each side of the "breadbox" forward of the prop spinner?  Is that 3" scat tubing you are using?  Did you design any unfiltered, alternate air sources to mitigate a clogged filter (ice, dust, bugs, debris, etc)?

Sorry for all the questions, but inquiring minds................

Thanks

Brooke

> That was good info on your IO-550N install.  My installation is essentially  the same as yours, so I am very interested in your performance.  I am not flying (YET!), but I would like to know what to expect.  The CHT,  EGT, and oil info was enlightening.  What kind of IAS and TAS are you getting?

In fact I have seen no TCM installation with it.  I plan on doing a lot of cross country flying with my machine, so filtering the air might be an idea worth implementing.  Can you post some pictures?

>   We built our plane before pictures were all electronic but I can scan some in a couple days if you more details.  We are running –N, going on 625 hours on XL-5FG.  We do not have any cooling air going to the engine mounted cooler, but we are plumbed to a forward nose mounted cooler.  We too try to keep our CHTs below 380.  We will occasionally see 400s on a cylinder or two after climbout on a hot day after a quick turn fuel stop.  Typical flight shows CHTs from 300 to 360 with 2 typically our hottest.  We typically see 180deg on the oil in the winter and 190-200 in the summer.  We run LOP exclusively, typically see 12.5 GPH at 9,500 feet and if you believe the electronics engine analyzer around 75% power.  Besides saving gas we have seen that ROP increases CHTs 30-60 and oil at least 20 degrees.  We are based out of Lancaster in California.  Because of all the dirt and dust out here we did spend the time to build an air intake with inline air filters, that’s probably the only unique thing about our install.
