Adding Cowling Louvers / RV-10

Geico266 · #1 05-26-2008, 07:35 AM

I need to add a second set of louvers to the bottom of my coweling. What are you guys using for additional louvers? Are they coming from Vans or are they after market? I searched, but got caught up in the "tunnel cooling" threads and could not find it.

Thanks for any help / suggestions.

Thanks Mike, Dave.

I ordered the aftermarket louvers and will get them installed in the coweling.

Larry,

I've got a pair from Aviation Tech Products that I didn't use/need. Yours if you want them - I'm just up the road in Omaha.

Sweet! Man I love this web site!

Bob, They have 2 sizes, which one do you have?

A special thanks to Bob C.

I drove (

weathered in

) to pick up the louvers and check out Bob's newly flying RV-10. I can report I got to see both a fine example of an RV, and a fine example of the quality of people that is VAF.

Thanks Bob, I owe you a cold one.

My question is, why add more louvers??? I have almost 200 hours on my RV-10 and I never see over 190 cht in a climb or over 175 cruise and I cruise 75% all the time leaned to peak. (which if you check the lycoming manual is OK) I did see high temps before breakin, but not after. I am monitoring all 6 cyl egt and cht. I also run gami's. Just wanted to put my 2cents worth in. A lot of builders really worry about trivial things!!! Van has a great plane, doesn't need much improvement. A little more HP would be nice though.

Jim, Trivial? I'm not sure what your definition of think trivial is, but vapor locking and loosing engine power from a heat soaked mechanical fuel pump is not "trivial" in my book.

I have a temp probe in my engine compartment. The most I ever see is in the 180's climb, in cruise around 150's. If everything is baffled tight and properly installed (I used factory firewall farward kit) I just can't see why the heat problems. Not looking to cause a ****storm, just letting you know my experience.
