Cabin Heat Success in11AC's

[EDGEFLY]

I have been watching the various items appearing about the lack of cabin heat, the inspections of heating muffs required and the reported success of adaption of c-150 muffs as a better means of collecting exhaust heat. My Chief has what I am sure are original muffs (at least from a design point of view) and are then presumably going to be unsatisfactory. I am also doing what I can to tighten up the cockpit in terms of plugging holes everywhere I can find them. I would like to hear more about Chief specific problems and improvements which are practical and useful. But also, am interested in the degree to which success has been achieved. As in terms of comfort on a 2 hr XC in a reasonably well sealed and improved cabin heat system in some nominal atmospheric temperatures. Winter is just around the corner in Pa. and this is certain to be a topic of importance.

The Hansen Wilson, C-150 Type Mufflers and Heater Shroud on my C-85 in the Chief provides plenty of heat. The Heater Shroud I had was in pretty bad shape, having been repaired one (or more) too many times! Bill Pancake suggested Sonny Porch, (Yes that is his name, might be related to Dik Holder) in Florida. I contacted him and he made me up a beautiful S/S one. I have the same set up also on my 7CCM.

Plugging holes that leak air also helps, but I never even have to have the heater full on.

I have pictures of the shroud. I tried to upload them, but got an error message that the Board Attachement Quota had been reached, so I guess that the administrators need to remove some pictures or up the size of the server space. If you E-mail me RKITTINE at sign AOL dot Com, I will be happy to send them too you as well as the installation and Sonny's contact information.

Dale - I have E-mailed you photos of the Heater Shroud as well as the HW Muffler installation. Sorry I can not get them on the Forum. - Bob

Bob,

I have the pictures of the installation and the muff alone. You mentioned that you are using it with an 85 HP engine and have no problem with heat. My A-65 runs regularly at 140-150 deg F oil temp at altitude. Do you think this will impact the H-W heat output?

Thanks for your quick response.

Does anyone have a legion of 65 Horses running a H-W successfully ?

Dale,

I have used the HW system on just about every four cylinder Continental engine there is.

Works great on all of them!

Neither my C-85 or my C-90 ever seem to get much above 160 degrees. The exhaust gas will be much hotter than that, so I would think that you will have plenty of heat. I have a friend with a 7ACA with a 65 and he put a HW exaust system on it and he got enough heat for the front seat in his Champ, though a little colder in the back, mostly because the plane is drafty.

For whatever it's worth I have the Cessna 150 exhaust system on both my A65 Champ and my 0200 L16. Much better heat than the original 'left toe' warmer with the "y" pipe system (although they don't sound as cool without the 'pucka-pucka'. Very easy installation. You do need to either cut new holes in the lower cowl or cut and reroute the exit stacks slightly and they do need to be approved on a 337 but doesn't seem to be a problem. I have copies of approved 337 paperwork somewhere in my files.

MikeB,
I would like a copy of your 337 if you have it. Another question, do you know of any approaches which allowed use of the same cowl exits as we're originally used ? Is there a significant appearance difference after the modification is made ?

Dale

[MikeB]

Dale,
Send me your email address by my PM and I'll send a copy of the 337. I can take a picture of the stack exits and also attach a copy if that would help.

For more heat, install cabin heat on the carb heat side also. I did that and I have to stop to cool off on our winter ski trips; well almost. I use Hanlon-Wilsons and they throw a lot of heat.

[EDGEFLY]

John,

I asked about this question and got a lot of good info. Since it seems to be general agreement that there is a heat problem of some sort, I intend to implement a Hanlon-Wilson mod of some sort in the future. But, I'm a little confused about your suggestion versus those offered earlier on this thread. Do you have some photography which I could use to compare the two approaches ? It can be sent to my personal E-mail tmail51a @gmail.com if you have difficulty posting photos here.

First of all, Hanlon Wilson mufflers give a lot more heat than the old "Y" muffs. I installed cabin heat on both sides which includes the carb heat side. I installed a 2" Y tube between the muffler and the carb box inlet. The heat can then go to either the cabin or the carb heat box. When you pull the cable for the carb heat, the hot air naturally goes to the caburetor air box since the engine vacuum is pulling the heat in. It works great. I'll try and get some pictures this weekend. John

I went with the Cessna 150 system mostly because I was unable to locate set of the HW muffler system. Once in awhile they pop up on EBAY but either are in pretty bad shape or get snapped up quickly. The benefit to the HW system is they are included in the TC (at least on the 7 series) and the exhaust exits properly through the cowl. Whereas the Cessna system requires a 337 and it's necessary to 'redirect' the exhaust stacks somewhat. Either one increases the cabin heat greatly.

Mike-We just got to the point of finding the C-150 stacks need "a little re-directing" to work on a Chief. Could I beg pics of how you managed to make them fit? Many thanks!
