Electric Fan?

[mkiiisupra]

Some people say that electric fans are no good with our turbo'd cars.

Would like to put on Perma-Cool 19114 - Perma-Cool High Performance Electric Fans - summitracing.com

Rated 2950cfm and only 9.5 amps

So are the problems people have in electric fans going with cheap ones that dont pull/push enough air? Or is that simply not enough flow?

these have 5900 CFM however come with a hefty price tag lol

Anyways if electric is not the way to go, any suggestions for stock fan replacement with a more lightweight set up?

With this radiator / fan upgrade also doing oil cooler ... rerouting filter and changing to a dual filter also using the old oil cooler for the tranny.

As well as replace all my radiator hoses w/ steel braided lines, as well as oil and tranny lines....

Anyone ever replaced this stuff w/ steel braided lines? any suggestions, what sizes needed? How do you get them to connect to stock hook ups etc.

holy shit, 5900 cfms with the second one...479 bucks though. if i had enough money id sell this flexalite i havent installed yet and buy that one. dont ever want my car to overheat or spin a bearing or something.

the main beef with electric fans that people have is that they supposedly dont push/pull as much air as the stock fan. noones really rated the stock fan though, and as far as i know no numbers have been produced. if going with an electric fan, id set the temp a bit lower than usual and get a good, quality fan....no cheap junk.

i use the perma cool listed 19114 and i built a shroud around it , ok i'm using a fluidyne radiator too
i mostly cruise @ 160-170 a little chilly but thats cruising temp m 50-60 mph la la la type driving
once you start stepping on the pedals the temp adjusts .i use an electric sender temp gauge . the stock gauge sucks big time

It doesn't take rocket science to figure out that electrical energy can be obtained much more efficiently than mechanical energy (ok, but does take a little bit of physics). Electric fans is the way to go. It is much more efficient to power a motor via an electric current than a mechanism. Electric fans will get you more air flow with a lower energy requirement. It will take this energy from your battery instead of your gas, so be sure to have a good battery. And you don't need to be an electrical engineer to install them. The circuits are not complicated (reading instructions SOMETIMES helps).

I forgot, set the electric fans to pull. More are flows as a puller than a pusher. Or you can have one and one. I think the problem with people is that they don't set the fan so it blows air in the right direction!

^that didn't come out right, but you get the idea.

Oh by the way, 6 of one half dozen of the other, your battery doesn't just make voltage, its supplied from the alt. and that gets its energy from the crank and the rod to the piston taking power and gas milage. It would probably be more efficient but still pull power and gas milage from the motor

Yes, but the energy the alternator needs to resupply voltage in the battery is much lower than the energy required to operate the fan clutch. Gas mileage difference is hardly noticeable if at all, but cooling efficiency is what we're after. I was referring to the battery because a 30 ampere fan can easily drain a crappy battery.

are your saying i need 2 fans? one in front and one in back of radiator?
