  • Keeping the exhasust heat down in your car.

    I have seen the heat shields vendors sell and kind of thought they would be nothing more than rattling vibrators under the car. I did something different that we used to do on sprint cars they make a high heat wrap napa and o reilly have it and I wrapped the entire exhaust and muffler with it it is help in place with little stainless ties i would post a picture but it is under the car and would be hard to photograph. What have some of the others here done?

    Interesting move, i don't recall reading about anyone wrapping there whole Model A exhaust before. I have heard of wrapping headers for faster exhaust flow but i believe it also caused them to rot out sooner.

      My 1962 Corvair Spyder had the exhaust wrapped up to the turbo to keep the exhaust as hot as possible to spin the turbine.
      I bought some wrap last summer to use on my Studebaker to keep as much heat off the carb as possible. Today's gas sure causes lots of problems for older carbureted cars.

        I wrapped the engine pipe with kevlar tape to keep the heat from coming in around the pedals and blowing straight up my trouser leg. NOT comfortable!
        Only a limited success but there is no real answer. Very poor design!

          Very poor design indeed. Pity Henry didn't think things through a little better. I also wrapped the engine pipe but the first time I had the muffler disconnected, I didn't put it back. It was winter anyway!!

        So far it has worked well for me or seems to however i have not been able to drive and touch the floorboard.

          If you install an Aries muffler in place of the old common Midas muffler most vendors sold until recently, you will notice a dramatic reduction in floor heat. The old muffler was too restrictive, and not made to factory specs. You will also notice the engine running cooler and more powerful.

              As long as the wrap doesn't get wet, I've always wondered if wrapping them would have any effect on the life of exhaust pipes?

                Cannot say Tom never noticed any issues on the sprint cars we used it on, however 2many cars made an interesting point.

                  FWIW: For: Keeping the exhaust heat down in your car.

                  About ten (10) years ago I cleaned the bottoms of both of my "original" Model A wood floor boards with POR Marine Clean.

                  POR Marine Clean can "totally" remove petroleum based road grim, and all petroleum based materials embedded in the porous wood fibers on the undersides of original wood floor boards ........... or petroleum based materials embedded in any porous metal or cast iron.

                  After cleaning and thoroughly drying, I next provided and adhered overlapping, aluminum reflective duct tape, (from Home Depot), on the under side both floor boards.

                  If one studies the effects of today's often used "Radiant Barriers", (provided adjacent to a very much needed air space), one can find that this shiny aluminum reflective duct tape can reflect 97% of the radiant energy transmitted through a Model A muffler. This reflective tape, adhered to "cleaned wood", after (10) years still looks like it was installed yesterday.

                  For engine sound reduction and engine and muffler heat reduction, I provided a continuous layer of dense, 1/2" thick commercial carpet padding over both floor boards and under my 1930 Town Sedan floor carpet.

                  Because of the reflective tape, and dense commercial carpet padding, the floor carpet remains cool with no difference in heat transfer from the driver's side to the passenger's side which is directly over my Aries muffler.

                  (When one tries using paint thinner, gasoline, etc., etc., this thinner will dissolve petroleum based materials, thins these petroleum based materials, and drives petroleum based materials deeper into either wood pores or metal pores. Heat, like muffler heat, can later reactivate these petroleum based materials and cause them to resurface where duct tape adhesion becomes impaired.)

                  I never later bothered to buy a muffler heat shield.

                  ​​​​​​​Just hope this can help someone one day fighting muffler heat.

                    Hi Mickey,

                    If one goes to e-bay, POR Marine Clean is about $17.00 per Gallon; or just Google POR Marine Clean.

                    It works much,much better when mixed with hot tap water in recommended ratios. One Gallon can make at least three (3) Gallons or even more. A small amount in one's Model A greasy radiator can do wonders.

                    If no experience with same, please call their 1-800 number with a detailed description of what you want to clean and a technician can recommend the water/POR ratio ..... it has thousands of uses and can be reused over and over.

                        X2 on the Aries muffler. I spoke to Joe Davis yesterday morning about the heat shield and he said you really don't need it with an Aries muffler. Go to their website and read all of the interesting information. http://www.amuffler.com/

                          Thanks again Guys. I wondered about the pre-mature decay of the muffler and pipe. My Linda's feet got hot on our first tour (100 miler) and I quickly installed some dense foil covered insulation (very thin, about 1/2", it was for shipping frozen food) under her side of the rubber mat and she put a bath rug under her feet to help. I don't know what the foil alone did but my whole conglomeration got us through a 500 mile weekend tour. Now I've got to figure out exactly what is going to do the job.
                          You guys have such great, well rounded ideas for us "newbies". All of you (and a guy named Pete, "Mr Personality") were instrumental in getting my A on the road in 1-year and 1-week.
                          My only regret is that when I bought the car I told my 100 year old Mom that I would take her for a ride when I was done. She passed away just after her 101st bday. Too soon to ride in her "chariot". Darn!
                          Also want to say how impressed I am with the attention that Mitch pays to every single question or comment, not just from all of you experienced guys but with "EVERYONE"!! His site is very user friendly, easy to navigate and so complete, even for Model A'ers like me.
                          I'm including a pic of the finished (it will never really be finished) 1931 Sport Coupe (I know, my Linda looks better than the car) and my Mom looking at the A the day I brought it home.

                            Phil guys here have talked about this material getting wet and causing decay, well the muffler get hot this wrap does not soak up water so it is going to be dry unless you park your car in the pool. just my two cents worth.

                          Hey Steve , I’ve only wrapped one that was on the pipe into the muffler in a high performance Aries stainless muffler on this speedster I did for a guy. The wrap worked out well . I too think the Audie’s mufflers probably do a little better job of heat disapation. The one on my tudor doesn’t seem to get all that warm or maybe my sensitivity isn’t what it use to be.

                          my wife might say that too!!

                            I did not notice any heat on your floor boards, when I was trying to set back in my seat. Guys talk about rot but what muffler doesn't?

                          Steve I like your idea of wrapping the pipe up near the engine to help with carb and dist issues. It could cause a cold running situation but so what

                            I doubt it will have much effect on the distributor since that would more affected by the manifold, however i do think it could help with vaporizing after the car has set or help with heat related issues with an air maze or filter I will get a pic up of what mine looks like that may help.

                            Why would it cause a cold running situation Mitch? I suppose you mean in cooler weather to help with vaporization or the fuel could try to be a little cooler when it is trying to atomize.

                            That's pretty much what I meant, but it may also be a non issue as well when cold out. Fattening up the GAV may also help compensate during warm up.. Just some thoughts

                            Steve, if you make it over this weekend to Pere Marquette, you'll see how I used sheets of reflective tape on Sarah's floorboards like Chauv explained above. It cut the heat almost 75% in the cab. In fact, I might have a full roll of that tape laying around, if I do, I have it with me Sunday if you make it over.

                            Ed

                            Footnote, the floor boards were original to Sarah's birth and I bought new ones. The tape would never have stuck to those boards. I have an extra can of professional adhesive also.

                              I found a full unused can of 3M HD adhesive but only found about a third of tape left but it will give you an idea of what to look for.

                            Here are a couple pics of my wrap job it is an aries muffler I had a cheaper one on before fully wrapped the aries i wrapped as the picture shows I never thought about it at the time but I could also have wrapped the exhaust manifold after the back exhaust port but i do not know that would do anything for you. If you run an air cleaner I think this is where wrapping is helpful and I also believe it can help cut down on the possibility of vaporizing in the heat of summer, which is nothing more than my opinion.

                              Carolina, the material on my Sport Coupe top came with the car and I think it is a nylon??? and responds very well to Meguiars vinyl conditioner.

                              So guys, the consensus of opinion is that " wrapping sounds like a good way to go???

                                FWIW: Per above Reply No.10, the Home Depot type aluminum tape, (with 97% radiant energy and heat reflection), provided on my floor boards is not peeling after (12) years; and combined with the reduced heat with the interior carpet pad, my interior floor boards stay cool in 100 degree ambient outside temperature.

                                The very most important part of tape adhesion when providing this aluminum tape heat shield on the undersides of Model A floor boards, (i.e., cleaning only with POR Marine Clean), as stated above in Reply No.10 above is:

                                (When one tries using paint thinner, gasoline, etc., etc., this thinner will dissolve petroleum based materials, thins these petroleum based materials, and drives petroleum based materials deeper into either wood pores or metal pores. Heat, like muffler heat, can later reactivate these petroleum based materials and cause them to resurface where duct tape adhesion becomes impaired.)

                                I have always noticed in life that achieving good results when one is following instructions is very similar to achieving good results when is following detailed instructions for successful hunting dog training.

                                The very first requirement in following instructions for 100% complete success is, that the dog trainer needs to have a higher I.Q. than the dog.

I wrapped the whole muffler starting just below where the muffler clamps to the manifold and went down all the way to the muffler itself and did not wrap the bell part but started wrapping again at the...

                                  by Ayyy
                                  The Model A engine is typical of other cars of the era in that they provide a mechanism(s) to preheat the air/fuel mixture. In their day it was necessary to pre-heat due to the low volatility of fuels. With today's volatile fuels (for better or worse), are the pre-heat systems really necessary, or even desired, for a Model A? Cooler air is more dense than warm air, so more power could be obtained...

                                  by jordanka16
                                  Well, went for a nice drive yesterday, but my passenger complained of the heat on her feet. I already have a thick mat and a reflective insulating pad, but she said it was warm still. I have read that a lot of people have good luck with the aries muffler, for many reasons, but they do reduce the heat on the floor. The existing muffler is just some glass pack thing he had lying around anyway. I've...

                                  Asbestos heat/sound shield?
                                  by Gramps36Ford
                                  Under the vinyl flooring my grandfather installed was a ‘pad’. Assuming a heat barrier? Anyways, knowing how much asbestos used for products back then, I wasn’t sure if some of you knew what material it could be, if asbestos.

                                  I know the real worry with asbestos is continued overexposure, but still was curious. Almost looks like old carpet padding thats SUPER weathered and deteriorating....

                                  connecting muffler to exhaust pipes without welding
                                  by ClaudeC
                                  Where Can I purchase couplings that can be used to connect muffler to exhaust pipe without welding? I assume it would be a thinner fitting that inserts into the muffler and exhaust tube then is clamped in place.

                                  by Dennis
                                  Does your exhaust pipe rattle at certain rpm? Recently I noticed at certain rpm or when I back off the throttle I get this rattling sound that sounds like it's coming from the exhaust pipe. I know it's not the engine pans, ran without them for a road test. Everything else is tight and when I bump it with the palm of my hand no rattle. If I bump the exhaust pipe after the muffler body I can get...

                                  Does anyone know if those distributor heat shields work to keep condensers from burning out? I have had to replace 2 in less than 300 miles. I have the modern set up with the condenser mounted on the top plate.

                                  Firewall Insulator
                                  by Jwmckenzie
                                  I just picked up a molded firewall insulator from someone who purchased it and then decided to go another way.

                                  The insulator, according to the packing slip, was made by Timothy Cox, now QuietRide.

                                  I have laid it up on the inside of my indented 31 firewall, The firewall has a slight bend forward just above the terminal box that is not molded into the insulator. When I put...

                                  Differential and Torque tube heat build up
                                  by 40B1930
                                  After my 20 mile donut run the differential housing was feeling more than warm and gets much warmer where the torque tube mates to the differential. Is this normal? I’ve got 1,200 miles on a “complete” rebuilt rearend and was not aware of this until I went to flush the housing. Is the heat normal or a concern? Thanks!
