You're missing the whole big flaw in this......boost pressure means absolutely nothing if you don't have the flow to back it. Leaf blowers cannot provide both enough flow and positive pressure to be of any use on any car engine, especially one of 3.3L


Go ahead and try it if you want. I'm just letting you know what the outcome will be.

I have to agree with boxersix on this one. It's been tried time and time again, and it has failed everytime. You MAY get like a 5hp increase UNDER 1,000 rpm, but it would aboslutely choke the car after that, and then probably come apart and ruin your motor.

A fellow prober tried this on his '96 Probe GT a few years back when morons first had this idea. THe fan blade on the blower flew off into his intake and... long story short, caused his motor to explode.

But go right ahead and see what happens... You are effectively bringing a rubber band to a gun-fight though.

I bet there are more than 1,000 threads about the electric "hair dryer" and approximately 1,000,000,000 replies saying "don't be an idiot"

watch the video, it's been done

with dyno evidence to prove it

so, all you have to do is figure out a way to tap off of your main fuel line, then create a pressurized reservoir for the 2 cycle oil, and then figure out where to mount the leaf blower motor and you're golden! What a concept!
I did like the smiles on the guys in the video along with the guy walking around with the "NAHZZZ" bottle. I'm guessing this happened late in the day after some serious bench racing

baught an electric leaf blower today, it was 40$ and it has 405cfm... thought it was pritty good.. hooked it up and used it normal way and it moves hella air... but i tried using it with my power invertor on my car and it didnt even work... now im going to have to use like 3-4 batteries in the back or a better inverter , my air filter fits perfectly on the blower, it also came with a switch so im able to put it under my peddle for WOT... i put my hand over the air and tried to block it, it was extremely hard and therefore i know it creates psi... ill let everyone know more later...

I'm just looking forward to seeing where it's going to fit under the hood!

[cruisen_15]

i will most likely be using it in my fender well, that way i can also add cold air to the mix.... i plan on increasing the cfm by upping the amount of amps and voltage the motor takes.. this motor is something you would find on an electric scooter...

The only SUCCESSFUL electric S/C kit that I know of uses 3 compact starters to power the unit. It requires having an additional alternator as well as 3 deep cycle batteries. It can only be used for about 15 seconds at a time and then you need to let your batteries recharge for about 10 minutes. I think it was tktturbo.com or something.

You still haven't addressed what you're going to do for fuel IF you can create enough pressure to actually be useful...Seriously, I think the amount of effort you're spending is going to be absolutely fruitless. It's not that it has to just make pressure on nothing, this "blower" (and I use the term loosely) actually has to FORCE air into a motor that already takes in a large amount of it. I still see very little chance of this being worth your time.

well, lets take a vote who thinks it will work and wont work....

If you search it, theres tons of Forums who ask the same questions i do and they all say some one should try it....

im gointo make a video of mine today, its pritty sick...

If it works, wont my MAF add some fuel to compensate? i doubt ill get more thean the 250hp mark where it does stop giving more fuel...

[LetItSnow]

Don't take this the wrong way, but have you found a single how-to?

Leaf blowers are made to blow leaves, not to boost cars. That's what real superchargers and turbos are for. Leaf blowers are not designed for car use. I vote fail.

I second that vote, but the failure will be SPECTACULAR!

$$$ to make it "work" VS your overal gain = failure(performance wise) big time.

If it was this easy I'd be out of business, and that's a fact.....

It's all in the math...you're going to need a certain amount of horsepower to drive a compressor to reach a certain flow rate and pressure level. Just plain Physics. How much horsepower do you think it takes to drive a turbocharger? I can tell you 3-4 car batteries isn't going to be enough to drive a motor powerful enough to do this(it's in the amps, not volts). 6 or 7 maybe, and add up the cost of batteries, wiring, rigging, blower, switches, etc and you're talking $600+ for a mere 5hp gain maybe. Maybe if you used a 5-6 hp brushless motor drive system and controller to spin 30K rpm and a hose of batteries to power it around 36Volts then again maybe
you'd see a slight 5hp gain.

Hey it's your money. Do as ye will.

And that video used a 4-5 hp GAS powered blower on a small disp Honda. And who knows who ****ed with the correction factors on that dyno to "prove" a point. Were' talking a motor with ~1.5 liters in disp over that honda in the SVX. and when it all boils down to it...the math doesn't lie.....

i really like at both sides of this build, but i wont exceed 100$ in this experiment... i accept failure but i have lots of free time right now so i figure its some educational time on forced induction...
