Looking to dabble into all possible heat dipersant ideas commonly available and have been looking into various coatings and the like.

I see alot of thermal dispersants applied to intakes on the bottom only and a lot of ceramic type coatings for the headers and the like.

What is out there as far as doing an entire intake setup, like base/plenum/runners or a Stealthram upper and lower?

Also doing air intake tract also if the intake will be gone for awhile.

Does someone have some datalogs or evidence of tempature drops after coating and pictured of said coated parts?

Just curious and trying to find some good solid input from people who have done this before.

Just my thought, but if you ceramic coated the whole intake, eventually it would become warmer than a none coated one...i/e once heatsoaked, there would be less heat escaping over.

Could be why only the bottom is coated?

 

I was thinking about possibly coating the bottom base of my stealth ram to keep the crankcase heat off the runners (if possible) Since its still not installed yet.
Seems like the runners will get heat soaked and with all the surface area under there in the valley, could heat the air charge even though they are shorter.
I'd be interested if there is a true thermal barrier material that could survive in that enviornment without flaking off.

 

Wel, I have been doing research and there are thermal coating ie insulators as well as heat dispersant coatings ie heat shedders lol

Thats as far as I am going on the physics of it lol

But, I am quite sure there are a variety of coatings that would work and last in auto environments.

Think about coating headers? It survives exposure as well as the elements.

They also do coatings on bearings now(anti-scuffing/friction) and do piston crowns and cyl head combustion chamers and runners(exhaust).

So I am sure an intake prepped correctly and coated with the proper materials in proper fashion would work also.

I'm just looking for the next great idea and see what is out there that people for the most part have been ignoring

Milodon Valley baffle is cheaper than the coating and isn't connected to the intake if you swap.

I did my piston crowns and it was easy. Just time consuming.
Need to research the application company too. Some don't have the QC needed to ensure too high a temp isn't used. This will in turn lower the hardness on your pistons and could lead to zero compression in a cylinder. Especially in a boosted app as your planning.

 

many years ago a friend of mine ceramic coated the bottom side of his intake, the tops of the pistons, the combustion chambers, the piston side of the exhaust valves, & the exhaust ports from the valve seats on out on his dirt car. he also had the piston skirts coated with teflon.
it seemed to run good, but he had problems getting it up to temp & keeping it there.

like i said, it was a dirt car so it didn't run for very long at a time. as to how doing the same thing on the street would work i don't know.

 

My engine is done and running NA currently until project turbo begins once I have a job(being unemployed sucks, kills u on $$$ for your car habits:-()

I'm looking for new methods on shedding IAT temps and keeping the underhood and engine as cool as possible thereby attempting to minimize the actual heat soak effect.

Looks like if I dig hard enough, I can come up with some rather intesting things to do.

Believe I am going Stelthram when I can get one for the vortec heads on the Formula ans more than likely getting the intake coated and the headers as well(why i didnt do it ion the first place i will never know)

It seems to me that an insulative coating would work very well on the intake, if it was coated on the inside of the runners as well as the underside. Less heat transfer from the intake walls to the air charge means lower IATs, right? I don't know if fuel exposure would hurt the coating, but in a dry-flow manifold you shouldn't have to worry about it anyway.

All thermal and dry film coatings are worth it of you can do it.

EVERYTHING, bearings,lifter bores,cylinders,bearings,pistons,valves,combustion chambers, etc are getting coated in my 400+ inch sbc w/ a large single turbo

 

Reading up at techline coatings JP, they do say to coat the underside and mounting flanges of the intake.

That means bottom and intake to head flanges :-)

Just cant believe someone here hasnt piped up with honest to *** data and an entirely coated intake setup.

I know they are out there or they coated them for show and dont care about go..

PS it could glow in the dark(that would be cool) and I wouldnt care as long as it made a real difference

I did see the note on doing the intake flanges. I never though about how much heat is actually transferred there. I would think the gaskets would insulate a fair amount on thier own. just looking at the underside of the HSR made me think about all that surface area and the heating effect on the runners.

 

Thats because Nobody goes in depth to get Real #'s that will show anything.

In order to do so you would need to do a base dyno run on a engine stand. Then do a tear down and coat 1 part. Say bearings.

re assemble and test again.

tear down and coat rods. test again.
tear down and coat cam test again
tear down and coat lifters " "
coat pistions " "
coat cylinders " "

Etc...

VERRY VERRY VERRY costlly to do a in depth test like this.

EVERY little bit helps. coat anything and everything you can afford to get done.

my 400+ sbc is gona be all show and go.
Coating EVERYTHING. lifters,bearings,block,lifter bores,crank,cam,etc....

 

I would think that someone would have some hard data on heat soaking and intakes :-)

Find it hard to believe, oh well, have amth for I can get a intake anyways, guess keep hoping somone pipes up.

I dont argue that the coatings work, I know it does, just looking for some real numbers and someone who has done an entire intact tract.

I've got my SR intake, runners, and Plenum ceramic coated, but I did it before I ever installed them, sso I'm afraid I'm not much benefit for ya on this.

Did you ever get a way to transfer that BIN?
