Don't stop working on it. Just change your plans. Instead of a leaf blower, what about a different source of electircally blown air? Something with say high cfm at low speed, and that which increases as the rpm's go up?

I'm reminded of those little electric race tracks i had as a kid. And strangely, I remember looking at the little guns that you used to increase it's speed, pull the trigger and it would go faster. I wondered how that worked, and noticed i could see through the vents something attached to the trigger that moved across a metal piece. That's how it changed, i thought, the metal acted as a variable resister, the current had to travel across more metal, thus reducing hte current traveling through.

I've thought of this before, using the same theory behind the blower. Unfortunantly, the blower needs to coorispond with engine rpm, not the throttle position, but it could still be done.

There are many opertunities out there for this. Also, if one isn't enough, what about 2, or 3? If your honestly curious, don't let the fact that a leaf blower won't sustain you. That just means you need something a bit more beefcake.

You'd need to find the cfm at WOT at 6500rpm. Then, find an air pump that can produce say 4-6psi at that cfm rating. Then, built a sort of variable resistor that will take advantage of engine rpm, simple as adding a pulley to the serpentine belt or removing the AC and using that. Then get your base cfm at idle. Find a way to scale it from say 1psi at idle to a steady 6psi or so at 6500rpm.

It's been done. It's not reinventing the wheel. If it was, we'd all drive ford model T's. Google is your friend. Industrial websites are your friend. They use blowers all the time, and big ones. I say keep at it. Go for it until you get bored, but don't get discouraged because one idea didn't work.

What I was going to say in a nutshell, What people where saying is a leafblower isnt going to cut it, but you are on the right track. Just gotta tweak your idea some.

in short.... stop trying to spend money on forcing air into your engine until everything on your car is in GOOD working order... All I see if your posts complaining about how bad your car runs and then these....

Maybe it will help you understand if I fill in the blanks for you

because the alternator cannot supply enough current to run the car's electrical system and the leaf blower at the same time.

so i was looknig around the power equipment at the store today and i noticed the cordless saws that use 18v+ and have a bigger motor then my blower , its simple, ill just buy a battery for the saw ?? they sold 19.6v batterys for it though, but didnt say how many amps

We have a winner! Your choice from the top shelf.

I was hoping that, in the interest of science, some would be conducted to come to this conclusion. I was also hoping that our OP would be willing to do that, in his pioneering efforts. Alas...

plain and simple electric supercharger suck.I've looked into it 6 months ago, they don't provide enough boost to do anything.you probaly saw the same you tube video that i did were the guy claimed to get 14lbs of boost with a vacum motor or was it a leaf blower, ethier way it's a waste of time and money. source yourself a turbo out of the junkyard out of a capri or a probe,miata something that nobody normally thinks of, and look into www.ststurbo.com for a idea that will works.oh yeah thomas knight madé/makes the closes thing to a fesable e-supercharger and what i've read he sounds like a con-man. i seen STS on a show called "two guys garage" looks nice and no intercooler need
good luck

I wouldn't really just go and get any old turbo though. I mean, sure junkyards are a good place to start if you're scrounging, but all of the turbo cars mentioned have turbos FAR too small to be worth putting on our motors.

[cruisen_15]

i know alot of people having been waiting for this but, F MY LEAF BLOWER!!! IM GUNA DO THE STS AND PUT A TURBO IN THE BACK OF MY SVX, HELLA ROOM BACK wHERE THE MUFFLER GOES!!!! i mean, damn it seems so simple, sure the fuel system will be hard to upgrade but just look at how easy it would be not having to cram a turbo in my engine bay

[Trevor]

Hot stuff?

[redlightningsvx]

what about putting in an STI turbo in it.

[cruisen_15]

yeah i really need to be boosted before june, thats when my high school drags come up and i really need to show some people up talking crap , sure its bracket racing but i atelast need better times then the kids who think they can beat me , anyways i just got a job so i should have money to do alot of this stuff cuzz i have no bills to pay except buy gas

You're gonna blow your car up.
