Need EXTREMELY strong DC fan

[morpheus kain]

I want a DC fan that is going to push about 200cfm. Yes I'm serious and no this isn't for a computer! Me and friend working on forced induction!!!

[Thor2003]

try a small blower motor out of a car heat/cooling system...should be around the amout your looking for...

good luck

[BipolarBill]

How big?

[morpheus kain]

Preferably as compact as I can get it Bill. Thanks Thor we're looking at that. Forced Induction means superchargers/turbochargers etc.

Thats the only one i could find, but its AC

How do you feel about a inverter and using those creative wiring skills of yours

Is this forced induction system for a vehicle?

Sorry to burst your bubble, but a centrifugal fan isn't powerful enough to provide any meanful levels of boost to an automobile engine.

You need something like a roots blower or a turbine to make real boost.

Yeah ! Make it two !

Looks like where going to experiment with a blower motor (possibly a leaf blower ) combined with a ram air solution. Thx for the HELPFUL replies.

The leaf blower idea is better, but I'm still not sure if that will make a huge increase.

If you haven't done any of these mods yet, do them:

Low restriction intake and filter (i think you know about this)

Low restriction exhaust system, including headers or a ported exhaust manifold

New spark plugs

Underdrive pulleys


Only then should you worry about pseudo forced induction.

[morpheus kain]

:-D all of that's been done. We're serious car nuts

[gjimene2]

well, what is it going to be used for?

if you got 30bucks to 50 to dish out, get a Toro Electric Leaf Blower. it's AC, but heck, it's good

or you can get a small compressor and charge it up

but my recomendation if it's going to be DC used, my best bet is a blower that uses a drum fan, or a turbine fan, but the turbine can get pricey.

Thanks for the thoughts gjimene2!

Ahhh, but thats why you have centrifugal superchargers... basically a belt drivin turbine instead of an exhaust drivin turbine like a turbo... And centrifugal superchargers produce a lot less heat than roots style blowers.

Roots blowers aren't as efficient, but they make better boost at low rpms than centrifugal turbines do. I still think exhaust driven turbines (turbochargers) are best.

MK: What type of car is it?

We've been tinkering with a Camaro (mine) Porsche 928 (my friend's and a GD nice ride!!!!) and an Eagle Talon 2liter DOHC (other friends). I have a V6 Camaro :-( and when it was purchased I expected it to be a slow POS. Hehe luckily I was wrong! It will lay some rubber. Granted it's not an LT1 350cc engine BUT it's still fun to drive. (I don't particularly need to be wrapping it around a tree, which I'm sure I'd do with about 300HP)
