Seems that as I get the bronco more refined and have the kids with me more I want it to be quieter inside and figure out some way to control floorboard temperatures. I saw Lars and maybe Tony are interested in some NVH improvements also so here is what I have found. I am hoping people can chime in with what has worked for them, or what hasn't!
Temperature control options:
The one issue I am running into is I don't have an interior in the bronco to hid any of this stuff. It has bed liner on the tub and stone chip paint on the inside of the hard top. What are people running for headliners? I see there are stock style ones for pretty cheap or ABS ones for more $$$.
Am I missing anything? What has worked for you guys?
Temperature control options:
- Reduce exhaust heat with ceramic coating or heat shields
- Adding ceramic coating, especially inside the exhaust where it works the best, is either expensive or really difficult. If you want ceramic coating buy the components that way! Has anyone found a good way to DIY ceramic coating?
- I am already on my third set of headers, should have spent more money and got ones that are ceramic coated from the start!
- I bought some fiberglass/dimpled aluminum heat shield that I zip tied to the exhaust where it gets hottest - the results have not been amazing but at least it smells bad? Has anyone found a better solution?
- Thermal insulation on the floor using lizard skin or other conduction barriers
- I added ceramic balloons to the Raptor liner when I sprayed it, and it doesn't work that good. It sounds like to get a good thermal barrier using lizard skin or similar it needs to be 1/2 inch thick! I could also add carpet but it would get pretty wet when it gets hosed out! lol!
- Radiant barrier on the floor like using gold foil on the bottom side!
- If it is good enough for a McLaren it is good enough for a bronco! Broncos are precious metal right?
- Summit racing makes some sounds deadening that has a foil top coat and a butyl backing. I am considering trying to put it on the bottom side of the floor boards to control both sounds and heat. I am hoping that if it is installed really carefully it won't trap moisture. Has anyone tried this?
- Weather stripping and sealing
- From my experience with houses - air leaks let in a lot of noise. But I don't think there is much more I can do on this front for my build.
- Spray on options like lizard skin
- I have heard good things, but it needs to be thick, there is a reason lizard skin comes in a 5 gallon bucket (or 3 gallons or whatever it is).
- stick on options like dynamat
- Like I said above, I bought some of the Summit Racing brand stuff for my 1950 ford pickup and it says it works as a thermal barrier also, so I might try it?
- Carpet - Nope!
