Exhaust wrap?

[GRUNTMAX]

Have heard a few good reports about exhaust wrap on headers, making the heat pass through quicker and less heat near the legs, engine running cooler. Anyone tried it?

Why Header Wraps Suck ...
Why Thermal Ceramic Coatings are Recommended

Good find Gruntmax Note that ceramic coating like the Jet-Hot actually lowers the headers temperature and not increase it like the wraps do. That makes some sense. Still the power gain would really be very minute and I doubt worh the money for an average busa rider. Cheers

The O2 % of ones exhaust gas has zero relativity to the performance of one's turbo charged engine as all the exhaust gas is doing is driving an impellor which drives a compressor on the other side of the turbo.
example: Pump a high pressure gas cylinder up fast and it gets hot. Stop pumping, note the temperature & pressure of the gas bottle. Check 5 minutes later when it cools. Low & behold, less pressure which means less density. Cold air is less dense than hot air

You confuse the density which is a ratio of mass to volume and applies to all solids and liquids with the pressure that only makes sense for gases and it simply indicates the amount of energy contained in a gas. In your example with a gas bottle the pressure drops as the cyliner cools because some of the gas energy is lost as a radiant heat. At the same pressures the hot air is less dense than cold. That is why in winter the engines develop more power than in summer. If hot air was more dense than cold, we would not have a hot air baloons and the chimneys would not work, and there would be no gliders or tornados either and the condors would be droping to the ground

Once again, you are referring to induction temperature instead of exhaust gas temperature.

Lowers the external header temperature. Not the internal header temperature.

....although, I wonder how the increase in internal exhaust temperature would effect the service life of one's wide band, or for that matter, the narrow band OEM one ?

Yeah ,Good find Gruntmax & Thanks for posting it . Pretty much as I thought really, On a street bike ,Wank value only .

Cheers,
I'd found that one before when somebody was looking into piston coatings, although these guys will make you custom coated pistons if you want. Also a Bob Carr or sociopathic insurance company lawyer wank unless your going Supercharged, Turbo or High Compression Stroker Motor
