As title states - I'm venting my OEM hood soon and since the Atlanta summer is crazy hot, I'm playing with the idea of setting up a fan or two for the underside of the hood on top of the turbo/manifold.

I'd need slim fans capable of high power, and components that won't melt from the heat. I think this would be a great way to help dispel heat and am excited to try this. Anyone think it'll work well/have suggestions for what type of fan to put in?

They make computer fans with metal housings so it wont melt that will run off of 12v power thats what I would use.

 

you'll be concentrating alot of heat through that fan so be sure it can take the heat.

 

You are looking to the heat from your manifold at 1200F.
I think your computer box will not even reach 500F.

The problem is the heat may melt the wires boot first, before the fan, if it is really made of metal components.

 

Does any one sell after market fans for the MR2 anymore? Can you get OEM fans still?

 

justin Putting the fans right above the manifold is going to just melt them even hi temp computer fans! Maybe try getting jet heat coasting on the manifold That should cool down your engine bay a good bit. If you do put the fans in remember extraction of the hot air as that is what the air will be doing anyway. The summers do get hot here but its the humidity that really pushes it over the top!

 

ATS has some nice stuff for the 3SGTE

 

I was thinking about the same idea ironically but I can't think of any clean way to pull it off.

Get some small ~60mm computer fans and bolt them underneath the vents in the hood and maybe splice into the radiator fan wiring so they turn on when the rad fans turn on or somehow wire them up to turn on when driving under ~10mph or w/e.

 

I'd probably rig it up to turn them on with a switch.

Thanks for the replies - the heat melting the components was an issue I thought about. However, there has to be a way to do it seeing as how the MR2 had them. I guess I'll have to look into some high temp fans that could take the heat.

If anyone else has any input - feel free to share

 

if the plastic AC / rad fans don't melt basically touching a 200F radiator and engine right behind them, I can't see them melting in the hood scoopes.

Granted the manifold gets hotter, but there is more air between them. Also after driving I can hold my hand over the manifold and come no where near to burning myself and I think I would burn myself before plastic melts.

The big question is how to make the install flush.
