I think you'll find that the fairing on Jim Smith's RV-6 without the louvers is much easier to build. He does 202 at 8000' dalt, 201 mph at 10,000' dalt, on 150 HP, and you can make it out of aluminum. It works on the Coanda effect

Paul, can you link to some pictures of Jim's fairings?

I wonder what having both mods would do to your speed?

What's the Coanda effect I too would like to see pictures of Jim's fairing. Thomas any clean up of your airframe will help make your plane more efficient/faster. But as your mods increase the results lessen. So the question is how much work are you will to do for very small gains?
The louvers really are not a problem to install it's more a cost issue for the louvers themselves. I am going to do alittle more testing with the louvers though, version 3, just have a hard time leaving things alone.
I have tried to stay away from posting any speeds of my plane but it does pretty good on a 320 also. Coming home from the "Badlands" this weekend at 9,500 pressure altitude we were truing out at 174 mph, 50% power, 6.4 gph, 2,450 rpm. We were heavey with all my wifes stuff for a long weekend.
One other thing about our plane I have not mentioned is we are running a fixed pitch "Performance Propeller" which I am very happy with.

Are you going to be at the Guthrie airport fly-in on September 24th? If so, I would like to talk with you. I have been interested in an exhaust exit fairing every since getting my cowl built.

Thumbs up Guthrie Fly In

Yes I'll be there. Looking forward to meeting you and talking RV's. The "Badlands" was our first long cross country in the 6, now my wife has the RV grin also and mine is even bigger than before. What a great traveling machine these RV's are.
Steve give me a call you don't have to waite for the flyin to come up. Also any and all RVs in the area come to Guthrie (KGOK) Saturday the 24th, like to have a good showing of RV,s here. FAA will have their altitude chamber here so you pilots can experience hypoxcia (sp?). Good food and several warbirds. Young Eagle flights. Should be a good reason to get out and fly to Guthrie that morning.

I am planning to make it up to Guthrie on the 24th. I will try to look you up when I get there but keep an eye on arriving RV's. If you see my red/white 9A (446RV) make sure to come over and say hello. Otherwise you might only be able to find me because I will be the one bending over looking at the belly of all the RV's trying to find exhaust fairings.

Steve,

There is a lot more to look at on Joe's plane than just the exhaust fairing. He's built a bunch of go-fast into that thing. I hope to see both of you there.

You won't make fun of me if I do goofy stuff in the altitude chamber before passing out will you? This might be a "double dog dare" opportunity that could result in some new call signs.

Joe

Looking forward to seeing all of those mods.

As far as any hypoxia joking around, well, I will reserve that for others as I am sure if I end up in that "chamber" it would not be pretty.
