  • f-19 exhaust

    I need new exhaust on my f-19 0-200 I live in North Dakota need all the heat I can get. Would like to up grade the cabin heat box also I have seen alot of modifications but what is the best? Where is the best place to buy? I also looking for a nose cone for this same airplane

    Re: f-19 exhaust

    Hello Daniel. I have this exhaust on my plane with C-85 and it helps with heat.

    http://www.taylorcraft.org/resources.html

    See the Cessna 150 O-200 exhaust mod for F-19 there : F19 Exhaust: installation of Cessna/Reeve exhaust Page 1 Page 2

    Best heat box is this: http://www.fadodge.com/ss-universal-cabin-heat-box/

    Check Wag-Aero and Aircraft Spruce for others or see the 337 above for a Cessna part number box as well: For example - https://www.aircraftspruce.com/searc...p?s=heat%20box

      I put the Cessna 150 exhaust system on my F-19 when it had the O-200 in it and it worked very well. I'm in Montana, so I understand how good heat is wanted. I still have the Cessna exhaust system and would sell it reasonable as I have put a bigger engine in.

        Note that the C-150 exhaust usually requires cowl bumps to fit under the forward bottom cowl. They are available here: http://www.crosswindsstol.com/index.html

          I should have a couple years left in mine, but when I do swap it out I’m going with the modified 150 exhaust. I called on getting a new stainless steal f19 exhaust made and it was gonna cost 2k+ And I’d still be using my beat up shrouds.

            I believe there's some power to be gained with dual 2:1 exhausts over the typical 4:2:1 configuration favored by some manufacturers using small Continentals. The Cessna 150 design is one option, the STC'd Luscombe system another: http://dc65stc.blogspot.com/2010/09/...onversion.html If nothing else they are a balanced design side to side.

            When tuning exhausts for power there''s lots to consider and the best are done with a running engine on a dynamometer that measures torque output across the range of engine rpms.

            The heat exchangers in the C-150 system appear larger and may be more efficient, but I don't really know if the Luscombe design lacks for that aspect. There are links on the net that describe how to improve the internal design of the Luscombe heat exchangers for better airflow across the heated header pipes.

              I’m mostly after better heat. Ski fling this winter in sub zero temperatures have been a eye opener. Usually when it’s 0*f I can get it to 30 inside and that’s using a insulated divider behind the seat, 20* without it. i already have a 150 system available but I bet the lucolmbe stacks sound a lot better.

                The Cessna 150 dual heat exchanger system does work well...for heat and power without excessive noise. The Luscombe's here are loud and C-150's are not as much for my ears. The Cessna has a much larger heat exchanger area. I have the left exhaust 100% into the cockpit floor with at curtain behind the seat, and the right splits to the carb heat for positive flow and to a firewall valve. That second valve opens or closes heat to a long 2" SCAT hose I use for defrosting windows or personal areas subject to chill. In non-winter when full carb heat is required I block off the split to the firewall. I'm good down to -20F but haven't measured the temps...above freezing tho as my dog rides shotgun and I don't see her breath.

                F-19's have a local reputation for lack of heat and many have been converted to the C-150 system, as once the original takes a s**t it's no longer available or cost effective to simply replace with same.

                  Re: f-19 exhaust

                  I went with the Luscombe a number of years ago. Louder, a small but noticeable increase in power and less cabin heat is what I got out of the change. Doug Combs built my exhaust and shrouds for me so I'd think that it was done right, but that loss of heat is a big deal for me considering when I do a lot of my flying. It may be that mine was one of those odd cases, but if a person is up in the great white north, look at other options.

                    Maybe this mod would help improve the heat from a Luscombe exhaust if it hasn't already been done?

                      Doug wrote that .pdf and built my exhaust exactly like what's pictured. Muff removal for annual inspection is a nice feature over the stock Tcraft exhaust also. I forgot to mention that above.

                        That's a disappointment. I'd make sure there is adequate airflow and also consider adding an annealed door spring wrapped over the header if there's room. I've done that own a few exhausts and it definitely improves the heat exchange over a flat surface. Might require some modifications to the existing design but the spring acts like fins that increase surface area, get hot, and pass heat on to the air better. Just like a home hot water baseboard heater. I like the power and simplicity of the Luscombe setup.

                          Re: f-19 exhaust

                          Hi. I own a F-19 Taylorcraft it has a luscombe exhaust on it now.I want to use 150 Exhaust system. Sounds like they require a bump in the lower cowling. I was reading on the forum that Atlee Dodge modifies this system to fit tighter around the engine so it dosen't need the bumps. I would love to hear more about this and the cost affiliated with this modification. I really looking for a system with more heat than I have now. I don't know if there is a preferred heat box to use,and to add the second heat box to spit off the other muffler. part numbers would be greatly appreciated If you have any other suggestions I would love to hear about them.

                            I have the Atlee Dodge modified exhaust headers on my C-85. They curve in so the cowl bump isn't required. It was done previously so I don't know the cost. Contact Atlee Dodge for an estimate. The cowl bump may be simpler and cheaper. A source is linked above.

                            Firewall mounted heater boxes are available from several aircraft parts sources. Do a search and the prices vary depending upon vendor. I used a 2" Y adapter to split the heat output from the right hand muffler, but a 2" SCAT flange adapter could also be attached to the shroud to offer a second outlet for the hot air.

                            All the above should be discussed with a mechanic before undertaking as doing and getting approval varies with FSDO regions and mechanics. Any previous modifications paid for by the owner are often proprietary and may not be available.

                            Dr. Tim Popp (astjp2) on this forum is a great source of this information. He has done several modifications and knows the process.
