order of hott components.

[Xsjado]

whats the order of items that get hot in the engine bay.
list them if you can in order.
what the buying worth on ceramic coating and can you diy it?

[visualpoet]

I'm going to go with:
N/A or SC:
Exhaust manifold/header,
coolant related (radiator and hoses),
the head itself,
the block,
the intake manifold.


Turbo:
Exhaust manifold/header,
turbo,
intake manifold,
coolant related,
head,
block.

They're all close together though, but I'm basing my choices on metal density, thickness and rate of absorption. Anything else is getting ambient heat and can be ignored as a heat source.

There are ratttle cans of ceramic coating out, how good they are at reducing underhood temps, I couldn't tell you. Whether it's worth it falls into the same category of my ignorance.

I saw something claimed 70% heat reduction and massive hp gains due to this.

going to start looking at ceramic coating brands ill effects. and most likely will be coating everything and anything removed from the engine.

why everything isn't coated from the factory if these claims are true is beyond me.

i don't think the radiator itself can be covered. unless you have steel type piping withi silicone.
as for doing the block i wonder what stresses mite be caused by not completely covering. ie/ not actually removing the engine just shooting whats visible.

a pretty paint scheme or chrome looking ceramic is in mind..

don't people replace their ceramic turbo wheels though?

soo much to look into and cbf atm honestly. lol

You need to think long and hard before you try to trap heat IN these components. They are designed to operate at an optimum temperature and trapping heat in could be detrimental to dependability. Really, the only element that can benefit from higher temps is the header or turbo & manifold. EVERYTHING else, you want heat to be able to freely escape or you risk overheating.

Coating all your components with ceramic more likely gives you a 70% greater chance of engine failure.

detrimental to dependability FTW

I'v heard around 40hp on unkown car just from headers. traping the heat from the engine bay but i don't think it makes any more heat.
may be completely wrong but damn...,

maybe just for upgraded parts?
also exhaust gasses are meant to pass through quicker.

thr problems are from wraps which have hot and cold spots.

edit: also engine bay components are kept cooler. less fatigue.

The only cars gaining 40hp from header wrap are nascar and formula1 cars. It is true, wrapping or ceramic coating a header traps heat in, increasing the velocity of exhaust which is a performance benefit to high-output engines. The stock f22 probably gains .5-1 hp from header wrap.

Also, wrapping headers has been known to increase the heat so much that welds fail and the header starts leaking. Some have been lucky with no problems but it is hit or miss across ebay, dcsport(crap), megan, and others. My Bisi header is ceramic coated but then it is DESIGNED to operate at "ceramic coated" temperatures. There aren't any other headers available for the f22 that use the quality of SS tubing and welding required for durability at those high temps.


Do not ceramic paint your block, it'll trap in heat creating higher oil temps and lower oil pressure likely causing bearing failure.

Do not ceramic coat your head, it will create higher coolant temps AND oil temps creating the oil problem mentioned AND extra stress on the radiator to remove all the heat.

Do not ceramic coat your radiator. The radiator REMOVES heat from the engine. If you trap heat in, it can't get out. Your block overheats, oil boils, bearings lock up, blown engine.

Do not ceramic coat your battery, this would just be stupid.

Do not ceramic coat your oem manifold, this would ^^^^^.

Do not ceramic coat your aftermarket header, it is likely to crack and the performance benefit is negligible. If you have any header other than Bisi you don't care about performance anyway so why bother?

Do not ceramic coat your power steering pump, it creates heat and that heat needs to escape.

Do not ceramic coat your alternator, it creates heat and needs to escape.

Do not ceramic coat your A/C pump, it also creates heat that needs to escape.

Do not ceramic coat your A/C condenser, it removes heat from the cabin, trapping heat in means it will not work as well.

if youre going to coat something, coat the valves and pistons.

[Xsjado]

dont want to touch internals til this engine gives up the ghost.
only ever plan on modding a fresh engine.

[19dabeast85]

Yeah man, spray some ceramic paint on those, haha!


But yes, a professional ceramic coating on the pistons and valve would make more power AND decrease external heat produced by the engine.

[GhostAccord]

Piston tops
Combustion chamber
Valve face
Exhaust ports
Inside Exhaust header/manifold

Anything to help maintain heat going out the exhaust port and into the exhaust. Therefore keeping heat from soaking into the block and head. This would be a performance upgrade. Coating the outside of the block, head, and radiator does nothing but hurt the cooling of the engine.

Don't forget about friction reducing coatings as well. Look up DLC if you don't already know what it is. Its almost a miracle coating.
