homemade heatshield / heat transfer.
if i use sheet metal to make some heatshields. do i need to paint it with anything to block heat transfer. or is the metal good enough.
platinum.

Re: homemade heatshield / heat transfer. (platinum00)
painting the surface facing the hot area with white or silver ceramic paint will increase it's heat deflection ability... Although polished metal is probobly just as good...
Oh and if you make it 2 layers with an air gap in between it will be even more effective.
IE
hotstuff |air| coldstuff
where the "|" are the metal sheets.
*edit*
And you should mount each seperate metal sheet seperately so there's no heat soak.

Re: homemade heatshield / heat transfer. (platinum00)
with air in the middle?? since when air is better conductor than metal for heat transfer?
are you aware that people/companies put a termo paste between a CPU and its heat sink? this is to minimize the amoutn of air molecules between the cpu (heat source)a dn the heat sink so maximize heat transfer.. conclusion: air is not a good conductor for heat transfer.

that may be, but these guys want to STOP heat transfer, NOT promote it....

Re: homemade heatshield / heat transfer. (trboCIVIC&WRX)
ahhh.. then i miss understood the issue then hehe.. sorry for the missunderstanding.. 
waht about that plastic material that is use to make IM gaskets? or any reat resistant think plastic would thansfer less heat that metal alone.
trully sorry for my post i should have double rear b4 posting.. an other for me..

Re: homemade heatshield / heat transfer. (kamaleon)
The only intake gasket that prevents heatsoak for OUR cars is the hondata gasket...
It's a metal gasket (I think) coated with a hightemp ceramic coating (white I believe).
The best material to prevent heatsoak is "phenolic" they use phenolic spacers on LOTS of domestics but none of the companies seem to be making any for imports...
I was thinking about getting them to make me like 1-5k or them for a certain price then I'd sell them.. but I ain't got no money.

Sorry to bring this back from the dead but thats wrong. It IS to promote heat transfer to the heat sink to move as much heat away from the CPU as possible so it runs as cool as possible.

Re: homemade heatshield / heat transfer. (hayabusa160)
I'm going to join all you thermal engineers and say:
1) sheet metal will do find (it will deflect/sheild heat from getting to your intake)
2) a thick aluminum would be better since that type of metal actually keeps cool when air is flowing over it. (think of the arc air box)
3) a gap with air will help keep inside/outside temperatures cooler than the warmer side.
4) no matter what you do it's still only going to be as cool as the ambient air temp. (with the exception of using the thick aluminum which will automatically cool it'self when air is flowing over it) (plastic does a similiar thing[comptech ice box])

Re: homemade heatshield / heat transfer. (slammed_93_hatch)
i had a ton of 1/4inch plywood laying around. and i took woodshop class for 3 years in highschool so? hey it works 
wood is a very good insulator btw
