Drastically lower underhood temperatures for a cooler and better performing ride with Jet-Hot's Classic Polish coating. The most trusted exhaust coating since 1982.
This coating is a thin ceramic metallic composite material with ultra low emissivity and high thermal conductivity, so yes the infrared view is picking up the reduced radiation emission not exact surface temp. The total heat loss to the system is reduced via the low emissivity aided further by hot spots being reduced from the high thermal conductivity Ultra low emissivity is another way of keeping heat in without "insulating" resulting in 2 advantages: 1) faster exhaust flow and scavenging 2) reduced intake air temp (usually about 1% power per 10°F) (varies depending on engine bay and intake set up) During this particular test, the exhaust gas temp measured with thermocouples in the exhaust flow was 50 deg hotter on the coated side than the uncoated side. If you want maximum surface temp reduction we recommend our 2000 and 2500 series coating which function with more intuitive insulation (low thermal conductivity) properties and also survive higher temp applications.
I’m glad you guys actually show something. Would be nice to have the temps displayed. But what about heat soak? Will the ceramic eventually catch up to the none coated? I do endurance racing, not drag racing so I need long periods.
the aluminum BBQ paint would also look cooler and also work at reducing heat emission for a short period, the aluminum would quickly oxidize and fail.. best case becoming aluminum oxide with higher emissivity, worst case flaking off.
lower conducted heat means that your exhaust gas will retain more heat. This means you'll have higher temperature exhaust gas. Given PV=nRT, the higher temperature translates directly into higher pressure in your exhaust manifold/pipes. That means by retaining heat you're actually reducing the flow of the headers.
@@chrism3188 similar to a supercharger then. Using power to make power. The benefits of the result outweigh the negatives. Id like to see variations on that experiment though
can you show us on the same engine a running max heat temp coated v uncoated. I dont care about underhood temp but on my old amc360 if it kept engine temp down that would be good
I know this May be a little late of a reply. Did you read what you wrote? You don’t care about under hood temps. But you want your engine to run cooler? Where do you keep your engine isn’t it under your hood? If you’re under hood temperature was lower would your engine be hotter or colder ? I’m just curious with your statement it didn’t seem to make sense. Maybe you could elaborate. Or maybe you could have your Coolant Jet Hot coated. Or maybe you could ask them if you could run Jet Hot Coating As Coolant!!!
Do you still recommend a heat shield? The shop that installed my Jet Hot 1300 coated headers did not reinstall the heat shield. Also my car is NA but just at 85hp/l, which I now notice your website recommends as the cutoff for going to the Ultra 2500 Extreme... Also is it possible to layer the 1300 on the 2500 for any added benefit?
Great questions, how is the coating holding up (the hottest spot is usually the first bends). Reinstalling the heat shield will only add more layers of protection (no harm to the coating) so if you want even more reduced heat then re-install them, if the heat is under control and you want to keep the exhaust exposed, don't. The 1300 can be applied on top of the 2k then given a satin finish this will give the best of both worlds (insulation with the 2k, + low emissivity from the 1300 satin on top). We don't advertise this given it will still cook the 1300 satin top coat at a temp lower than a full ceramic top coat that already comes on the 2k and 2500 so kind of fits in between the 1300 and 2k, but for someone right at 85hp/L it would be safe and very effective.
@@jethot Thanks for the reply. It's hard to see the headers, it's an engine-out install. Am I ok with the 1300 in my application if it is still intact in terms of temperature reduction? Also, is the coating just gonna burn off if it's at 85 hp/l? I'm thinking of getting an infrared thermocouple sensor and try to measure the temps with that but not sure when that will happen. In the mean time I am going to try to get the shop to install some kind of heat shield protection for anything vulnerable directly exposed to radiant heat from the headers...
@@chrism3188 thanks for the reply, looks like you might be signed in to the wrong account perhaps, but anyway, I still haven’t gotten a chance to install the heat shield; I did use a infrared thermometer to measure surrrounding objects after driving, they were hit as you’d expect but not crazy. Still not sure how I can install a heat shield w/o taking out the headers, but hopefully your 1300 coating is helping!
@AM D yes, this is my personal account (its a pain to switch on mobile), I assure you the 1300P (aka classic polish) is reducing radiant heat significantly. Too bad you didn't get any before measurements on same objects to compare.

It really has to equalize at some point, so yeah, thermodynamics says it WILL happen.
the ulta low emissivity will continue to reduce radiant heat even at heat soaked condition.
Wow, that is impressive.
amazing
Yes... I have a question... what would the video footage look like if you painted the bare steel header with shiny aluminum barbecue paint?
the aluminum BBQ paint would also look cooler and also work at reducing heat emission for a short period, the aluminum would quickly oxidize and fail.. best case becoming aluminum oxide with higher emissivity, worst case flaking off.
@@chrismelnyk1294 Hey! Thanks for the response! Do you work for Jet Hot?
@@blubunn Sorry for late response, yes I'm the Engineering Manager
Do you do diesel exhaust manifolds

Given PV=nRT, the higher temperature translates directly into higher pressure in your exhaust manifold/pipes. That means by retaining heat you're actually reducing the flow of the headers.
@LeonL47 it exits faster due to a higher differential pressure
Dyno doesn't lie. The majority of the gains are from reduced underhood and intake temps.

What did you use for the thermal imaging.
