Heat containment

Hello all,

I've finished the installation of the new Twin-H2 intake manifold from Dan White along with Clifford's headers on my 54 Super Wasp and made it's first ride to a small car expo.

It's running great and don't have major issues so far and I learned that headers obviously produce more heat than the stock exhaust manifolds and I'm suspecting that the cooling system might be slighly hotter due to the headers' radiating heat. Nothing too alarming but the heat is quite present even with the heater blower off while rolling on the highway.

I'm looking around to find a way to at least reduce the heat coming from the headers. Exhaust wraps is the first thing in mind, but I wonder if there is other methods that can help to contain the heat.

Other than this little issue, the car is running great and I'll be driving it through the entire season.

    My headers are wrapped, but it doesn't seem to help too much. I made a heat shield where the headers get close to floor, which does help a bit. I don't have any carpet or anything in my car, so the engine/transmission and road heat are really apparent. I hear that the ceramic coating on headers works the best, there's one specifically for heat control. I don't have any personal experience with it though. The aluminum head will radiate more heat under the hood than an iron head.

    Use some sort of Dyna mat type covering on the floor under your carpet plus some header wrap. Should help. Manifold looks good. I’m still retro-fitting my Hornet w the new parts but keep getting side tracked lol.

    Your wasp looks great nice plumbing job on the fuel lines any trouble with vapor lock ? Thanks John

    John, I didn't have any vapor lock issues so far ( knocking on wood ), but it is something that I'll keep an eye on during the summer.

    As for heat containment, I've some update:

    I did check for some infos for ceramic coating and though it could have been a good option, the process is very long if done the right way ( removing the header for proper cleaning before putting the coat ). So I opted for the header wrap as it is easier to install. It only took me half a day to do it while taking my time to do it right.

    As seen on the picture, it does look good and it did help a bit heat wise. I recently drove a couple of miles under a hot sunny day and the coolant gauge was just under half way. Naturally, it does bump up a little when driving in town or when when driving at high speed ( 60 miles per hour and up ).

    Not bad, but I would like to bring the temperature a little more lower.

    The car's cooling system is equipped with a 160 degree F thermostat and I want to know if changing it fo a thermostat that opens at higher temp ( i. e. a 180 F thermostat ) can help or not.
