Yes, I guess about 5 knots (which I use to offset fuel).
The big thing is even temps. My CHTs have evened out. #3 used to be hot. Now it as cooled about 15F and evened out, which is good in the weather we fly in.

Here are some fitting pics. I did take post painting pics, but now I can't find them  Sorry it took so long, since LA I have been to Singapore and Da Nang. Bridget is now in LA!!
Will keep looking.
By the way, I glued 'zircoflex' beneath the powerflow at the front, it really keeps the cowl cool now. I know you think it wasn't needed, but I took some temp probe readings in the cowl in flight and from in front of the cowl and showed the to the materials guys at the Uni where I am adjunct, they said that eventually the fibreglass may break down or distort. So it went on 
It is quite cheap and easy to do with cowls off. In Aust it is like your 347, just a logbook entry as it doesn't alter th actual cowl in any way.

Hi
Yes i have a lot of fitting and pot painting pics, they are at home, I am on holidays in the North because I have had enough of winter. We took the Grumman, its a ten hour flight.
Comments so far:
I guesstimate a 5 knot TAS improvement.
CHTs are now all below 420 even on climb. Previously my #3 would exceed 450 unless climb was faster than 90 kt.
Fitting went well, I have since had an EDM 830 fitted, the LAME (A & P) found the cowl easy to remove/replace.
Original fit the LAME allowed breather to drain to cowl. Yuk! I have since added air oil separator and the breather goes through gear leg opening.
In hot air (30C) front of cowl got very hot. We added teflon heat shield from aircraft spruce and it is now fine. (zircoflex).
Suggested improvements? I would reinforce and add camlock instead of screw for upper cowl.

I'm working on a new web page for my web site. It's going to have pics and comments from the owners and installers. If you could, please, send me some pics and comments on your experiences with the cowling.
I'm looking for things like:
• ease of maintenance
• quality of fabrication on the cowling
• CHT spread
• change in fuel consumption
• change in cruise speed
• installation instructions, clear or not
• any problems with the cowling
• reason for wanting/buying the cowling
Thanks Andrew. I appreciate the support. Looking forward to hearing from you and your experiences with the Jaguar Cowling.
Gary
PS, if you have a pic of your plane with the cowling, send it. I'll put it on the internet.
