Leaf Blower Forced Induction?


So in one of the many e-mails the team has sent back and forth some how a leaf blower came up. We briefly talked about doing some sort of ghetto-charging using a leaf blower and how we could most-likely could get one for cheap at Harbor Freight (They seem to have just about everything).



I did a little googleing and found this video;


I also found a product called the e-ram that is an high powered electric fan that activates at WOT (wide open throttle) providing about 1psi of boost.  http://www.electricsupercharger.com/products-eram.html

The e-ram is way out of our budget, and what fun is it to install some pre-made system like that when you can try and build your own.

There are then two options that I have come up with;

1. find a cheap leaf blower and find a way to power it.
2. find a high powered DC fan that would fit in the existing air system.

I'v not ever opened up an electric leaf blower but I don't imagine that the motor inside is a DC motor so we would need a transformer.  Not that big a deal but would increase the cost of the project. While the leaf blower would be cool and we might even need to cut a hole in the hood for it. The DC fan solution I think would be easier.
Since the car electronics are 12v DC a 12v fan would be the easiest to wire-up, but we could make or buy DC to DC up converters to get us to 24v or greater.  PC case fans might be the best place to start looking for 12v DC fans,


The problem might be finding one that creates enough air flow to make a difference.
So something like this;



Might be better and provide enough air flow, and still require us to make a hole in the hood to get it to fit.

Getting the whole system to work electricly in the car is something  I will get into in a later post.

  1. Due to the strength and speed of revolution of these centrifugal fans, manufacturers use them as the material for a leaf blower due to its high RPM capabilities.

    Also, to prevent back draft, we may opt to use a damper. Manufacturers created these kinds of materials in order to provide safe and high quality products for its consumers.
