Homemade Electric Blower

[WrathOfSocrus]

Flow and pressure are not directly proportional. Depending on the fan design one fan with a high CFM rating will have very low pressure and tend to have a large drop in flow when there is a restriction placed in its path. Then another fan with a lower CFM rating can have more pressure and less flow loss with the same restriction.

I know some people with radiators for computer water cooling systems will stack a pair of fans to increase pressure through the radiator fins. While it isn't perfect the rule of thumb is more blades with less pitch will give better pressure. If you look at the fan face on and see more air than you do blades then it probably doesn't have as great of pressure (again not ALWAYS the case).

A setup like that could help to overcome intake restrictions and in extreme cases even provide a small amount of boost, but it doesn't seem too efficient to produce the electricity at the same time you are trying to gain performance from it. Perhaps It could be more useful for smaller hybrid applications where the energy to power the fans could be produced under braking and then put back into the engine in the form of airflow when accelerating. It could be useful but I'm not sure how efficient it would be.

Dude I got it! Go Green, Use the patent pending K.E.B. Kinetic Energy Blower
It's a lot like F1's K.E.R.S system but instead of using a battery and all the Hi-tech jazz.
Us my Patent Pending K.E.B
Ok Get one Brake Venting Rims like the picture below! This Total bolt on
( with some mods needed) Kit. Quick application any where from 30mins to 12 and a half hours
Skill level Not Needed! woohoo!
Ok so you FWD guy this mod is even easier! Don't need that much drier hose from home depot!

Ok.. bolt on rim! what ever side is closest to your throttle body, buy 4-6 rolls of duct tape.. depends on how much beer you bought? any where from 3-12 feet for laundry room dryer hose "under 18 builders please do the right thing save money and take your moms dryer hose"
ok ditch the hole air box thing "it just adds weight, not really needed" duct tape the dryer hose to intake, route hose to wheel well, tape up all wheel well holes with tape, then use a 4.5" hole saw and drill hole in wheel well, tape
dryer hose to hole!
Now drive fast!
This will show gains!

so the airflow generated by the wheel? that seems like it would have been on a ricer by now...

[1988GTU]

Those look like shoguns ........ I think they are actually.

Naw the ricer guys like turbos.....



1988GTU: ya shoguns!
they look hot on my yugo with the K.E.B. kit, An honest 83hp on tap!

[95SleeperAcheiva]

you really got that yugo? I need the trans from it, mine dropped reverse.

I got an '89 with 45k original, 2nd owner. I've had it since '95 bought it from my dad. No rust, perfect condition, but I need a trans. a trans from a '91 will work too, only difference is thats a 5-speed.

[blownarrow]

Nope....!

[IsaacHayes]

then are ITB's the answer to the TB restriction?

[pocket-rocket]

I've read about the cheaper "electric superchargers" having plastic blades which, in the case when the engine winds out drawing more air in then the fans can push, the fans are spun faster then they are made for and the centrifugal force makes the blades explode and get sucked into your intake. Good thing you are thinking of using three of them

[robertisaar]

yeah, all the ebay ones i see are basicly squirel cage motors, meaning its a blower motor for your HVAC system...
