does anyone know where i can find an electric fan shroud?? i believe it was posted before but i cant seem to find it

 

I think you might be talking about the one from vintage air? Other than that most efans people run are off other stock cars and come with a shroud.

 

I used a shroud from Vintage Air on my old N/A coupled with a Perma Cool fan. There's lots of shrouds that Vintage Air offers that would fit. Check their catalog at http://www.vintageair.com. Some are precut and some are not. I paid around $100 for mine.

 

I use a 94-95 mustang gt electric fan and it fits great because you can cut the passengers side to fit. I've used mine for 3 years and the temp needle has never gone more than a quarter of the way up !!!!!

 

I used a cheap 16" mr gasket efan from summit combined with a diy sheet metal (aluminum) fan shroud.

Works great, weighs little, and doesnt take much space.

 

is the shroud even nessecary?

 

now, i know lots of really smart people will argue with me for this, but an additional shroud is NOT necessary, assuming that the fan you use has at least some sort of basic shroud around it.

people who say that the whole radiator should be ducted to a fan and sealed with the shroud are just downright wrong. ducting our large radiator through a 16" hole is a bad idea to start with, and when the fan is off, it restricts flow way too much. you need to consider the fact that the more restriction you put on the back of the radiator, the more tendency the air will have to just bypass the radiator and flow under the car.

when choosing a fan/shroud, there are basically two things to consider:
1) the fan should be as close to the radiator as possible, and should cover as much of the area as possible.
2) the only time a shroud is necessary is when the fan is not close enough to the radiator to pull air through it, and instead just stirs the air around in the engine bay. you want your fan to be sealed up against the radiator that it covers, but the area of the radiator face that is not covered by the fan should be left alone.

proper CFM flow for a fan is all you need to worry about, if the fan will flow properly, then theres no need to worry about air being ducted the wrong way, id suggest making your own shroud if its that much of a problem though.

 

a shroud helps, though when I did mine my primary concern was a clean and simple mounting method that didnt involve putting fasteners through the radiator core while still staying light and low profile.

 

I was able to install a 16" fan in the stock shroud. I like it. I never have over heating problems. It's simple remove the shroud and m-fan. use bolts or fiber glass on the new fan, wire it up and your done. The fan only comes on when I need it with teh temp sensor. It has never turned on while on the highway. Even in the humid southern heat.

 

i used an escort fan ,then i cut my rx7 fan shroud to fit it came out looking stock
