No, I don't have them just yet, but it looks like I should get after it by the number of e-mails and interest. We are in the middle of building a run of 200 RV-8 Ultimate Gust Locks right now. As soon as we get to a point where we can through these in we will make some. Thanks, Allan...

It's ok Allen. I was just yanking your chain. You have some good products and have been open to changes, good job.

Allan, I like the idea of a dedicated port into the exhaust, in fact I have been considering doing that for a smoke system too. I haven't pursued it in enough detail to determine what I would need to do to install one though. It looks to me like I would need to remove the exhaust pipe tails (last foot or so up to the swivel joint in the pipes) so I could have them on the bench to weld on the ports. Not knowing how hard that would be, it seems like a hitch in the plan, and i'm not keen to try welding while they're still on the plane... My fuel lines are pretty close!
Being able to just twist the pipe in that last swivel joint, drill a hole, clamp on a port, and twist it back into place seems much more do-able, and makes the process more attractive. Something to consider, maybe?

Right offhand I don't recall any application attached directly to the exhaust manifold. Can you suggest one?
A typical installation located the check valve on an air rail, which was in turn connected to the manifold...random illustration grabbed off the net below.

Got my fitting installed last night....well almost. I forgot the clamps.
This morning we were faced with a 2.5 hr drive to Missoula to watch the grand daughter play lacrosse. Instead, I installed clamps and cowled up. We were there in 40 minutes even had headwinds. Gut impression says I am faster. I've flown enough to know that 8.5gph gets me 177-178 KTAS between 9-11000'. Today I noticed we were holding 180 for most of the trip. I realize this wasn't a real test run but did make me take notice. I fiddled with the mixture to see make sure I was where I normally ran. Coming home it was too rough over the mountains for any useful data collection. I had the power pulled back. 5.8gph=150KTAS but still wacked around, so down to 130 and 4.? gph.

saddle
Brian, That looks very nice.The blue high temp silicone hose that I used fit very tight so I skipped that hose clamp.(less wt. shaking) I am at 8.8 hrs. with no oil on the belly and saddle assembly looks perfect. More hours will tell but so far so good. Ron

...This looks very nice and for sure will be trouble free forever. I think I need to pre-make some of this type of mountings for the guys that don't have ready access to welding equipment. It will vastly simplify the install and totally eliminate the possibility of cracking Etc. Now all I need do is find a source for those ultra high temperature zip ties and we will be good to go.  Thanks, Allan

 . I figure the zip ties will melt and glue everything in place....I replaced them with SS clamps that I had left in my other truck. Amazing they seem more secure.
Allen, I was going to wait for your product, but I had the plane apart and ability to roll my own. I flew 2 hrs today and ran at a higher oil level than in the past...so far so good.

sign me up for one of your systems as soon as you've got the clamp on saddle arrangement done.

I got my vacuum valve with clamps (thank you Allan), and i assumed it would be an easy install. Murphy strikes again!
Unfortunately, it turns out there is precious little straight runs in the exhaust system on the -10. I am still unsure of exactly where i can mount it appropriately.
It looks like most -10 welded installs put it right on the curvy part of the tubing, which won't clamp well with the clamp system.
There is a chance it will fit on the only straight section right underneath the firewall but the clearances are tight. Also, it will make removing the hinge pin difficult.
Argh!
