| im at work and dont have time for the math here, but you are being utterly absurd, or your just trolling me. Look, there are a million different ways to do "chrome" so lets just stick with a basic triple plate which is copper, nickle, then chrome. [ http://www.engineersedge.com/properties_of_metals.htm ]
Material Thermal Conductivity
Aluminum 136
Copper 231
Nickel 52.4
Chromium 52
A few different ceramics for comparison:
[ http://www.reade.com/Particle_Briefings/thermal_con_ceramics.html ] Material Thermal Conductivity
Manganic-manganous oxide 4.18
Lead oxide (mono-#, 100%) 1.6
Kyanite (b-axis) 9.6
Spinel (MgO.Al2O3) 6.80
Quartz (c-axis) 6.40 "thermal barrier material layer of ceramic material having a thermal conductivity of greater than 0.0 and less than 10 BTU.ft/hr.ft2. ° F., "

United States Patent 5413877 Ok, So keep in mind you will have to grind the hell out of the plenum in order to get it smooth. Far more will be ground off than will be added. Add in the fact that you have copper in the mix, which conducts FAR better than aluminum, and it more than makes up for the fact that chromium and nickle do not conduct quite as well. A triple plate of equal thicknesses averages out to 111.8. Chrome platting is NOT some magical motor sweatbox maker. Its all metals that conduct heat fairly well. The surface area argument is just as silly... This is an absurd argument. and i cant justify debunking it at work.
You are killing me bro. Look if you want your plenum cooler, install a hood scoop, custom venting, or use N20 to cool the intake charge or SOMETHING effective. I'm not saying ceramic coatings aren't great for increasing the efficiency, or decreasing the efficiency of thermal transfer, what im saying is you are trying to apply a small efficiency improvement to a system which doesn't work in the first place.
"all coatings eventually flake" - if it will hold up for a week on a piston crown, id expect at least 100 years in an intake manifold.
"ceramic intake coatings exists for a reason" - first, every application and manifold is different, and 2nd, the fact that someone is willing to coat your intake manifold does not constitute proof of efficacy. Compared to coating pistons and intercoolers (which makes sense), coating an intake manifold is still extremely rare.

These 2530's ain't half bad ;)
