helps pull heat from the radiator. drop it and your temps will rise when it warms up. look somewhere else to lose weight

It weighs less than a couple pounds.
You'd lose less weight not eating at McDonalds once a week.

The fan's purpose should be obvious just from looking at it. If ensures the fan can only pull air through the radiator. If it's not there, air would simply be pulled from the engine bay, and the fan would churn it around and around. Not much air would be pulled through the radiator.

You can't seriously consider that piece of thin plastic as a good weight saving idea...

yea you can, every bit helps. (i don't mean to sound like an a** hole)
If you do an electric fan conversion than you can remove that shroud and use the shroud on the e-fan.

Yeah, you do sound like an ******* - your words not mine.
I bet you cannot go faster without the fan shroud.
Care to put a bet on it?
1/4-mile or road race - you pick.

ok a fan shroud is a GOOD thing. basic automotive class will tell you that u need one to keep the air that gits pulled into the engin from recurculating. yes an e-fan would be better but only if you droped the clutch fan and the stock shroud. just keep the shroud unless you can afford the e-fan. it will save you your engine from overheating and getting messed up possibly.

I don't know what I'd use as a tool stand if I removed the shroud on my GXL. With that useless intake plastic removed, it makes a nice surface to throw things on.

Is this a racecar?

Ok as far as I know the average for weight loss is 100 pounds for every 1/10th of a second in a quarter mile race. So basically to drop a second in a your Quartermile time you would have to drop 1,000 pounds!

I laugh my *** off when all these street cars go about weight reduction in all the wrong spots. Taking a 3# plastic shroud off isn't going to do anything but heat your engine up . A hotter engine will not preform as well as a properly cooled one. Besides the heat issue a 3# reduction won't give you any noticable gain at all. Hell, even a 300# weight reduction is gonna be pretty hard to notice.

If you're making a race car, search for weight reduction and you'll find all kinds of things, like clues to the really heavy stuff. Like switching your steel hood to an Aluminum hood. Different exaust, interior parts(power locks, windows, etc)
think about doing things like relocating you battery to the back of your car

Read up a bit man, and don't take that shroud off!

Aaron: Does an e-fan with its own shroud weigh more than the stock shroud and fan it would be replacing? It doesn't make sense....

Oops...forgot about the weight of the stock fan and clutch.

It's probably VERY close though.

You don't sound like an *******, you just sound like you haven't put any thought into what you said. Exactly how much do you think this little bit is going to help? Do you honestly think you'd be able to even measure any performance gain, let alone feel it? Before you trot out the grossly overused "every bit helps" line, think a little harder about the reality of what you're saying.

If your stock clutch fan starts to go, you can replace it with a good (I mean good) efan, then you will have to remove your shroud anyway. Otherwise, everyone else is right to tell you to leave it on. The shroud helps when you're sitting at a light, to help pull air through the radiator, instead of all over the hot engine. But, on the road, the car is cooled by the air that is forced through the grille and a good bit by the oil cooler. That's why you can remove the shroud when you install an efan, because you'll find the efan runs most when you're stopped in traffic, not necessarily when you're driving.

?

I thought the point of having an e-fan was to take the weight off the rotating parts on the front of the engine thus giving u an extra hp or two ?

Like everyone said if weight were a factor getting the e-fan is useless

well my fan shround was cracked. so i took it of cause it was a eyesore to have to look at it broke. My car actually runs cooler since it has been taken off,and it runs slightly warmer than it did when i had the fan shroud on. just my .02 on this subject. but like i said the only reason i did it is cause mine was broke. if there was nothing wrong with it i would have left it on till i got a e-fan.

Were you arriving at this using an aftermarket water temp gauge? If not I would not come to that conclusion using the stock gauge.

It could have something to do with where the crack was in your shroud.

i really feel sorry for the people that actually know what they are talking about. they have to come here and waste a little bit of their time so that somebody doesn't take off their fan shroud for no good reason, overheat their car one hot day, and then get their hands chopped off when they go see what is wrong...
