I'm going to get an electric 200 MPH (should be good for 4-5 PSI) leaf blower from The Home Depot for $70. I'm going to move my air flow meter closer to the throttle body. I'm going to put a big *** K & N cone on the vaccuum side of the leaf blower. I'm going to hook the blow side of the leaf blower to my air flow meter. I'm going to plug the leaf blower into a power inverter. I'm going to mount a switch for the leaf blower in the cockpit under my AAS buttons. I will go faster. Muhaha!

Any ideas?

A couple of us were going to try and do this a couple weeks ago... let me know if it works

the problems we ran into:

Not enough psi
forced to much air through afm
drew around 6 amps for a small motor... thats alot of power


I can't help but think of doing it again every time i see a leafblower, but....

Now a Small gas powered one on the other hand.......

have you looked at the e-ram? it's an electric supercharger good for a bonified 1 psi... it is strong enuf to blow one of those fake fire starting logs around from a few feet away someone over at the i-club forums tried one

yea it should work fine, i would say put it after the afm for more flow of air, and only have it come on at WOT like the e-ram does, at WOT it has lots more advantage than being on all the time. i think it will work good good luck

oh also, if it is good for 4-5 psi, you will want to get some t2 secondaries and probably an apex'i S=AFC, might not need it but it would help, and a modified throttle body would let a little extra flow through

No disrespect but I think you guys are dreaming. All the leaf blower or e-ram is going to do is become a restriction in your intake. At low speed it will be a restriction in your intake because your car "sucks" air at low speed faster than the velocity you are travelling. I'm sure if you took you air filter off and completely covered the hole with your hand while someone revved up your engine you would feel this suction. No little electric leaf blower is going to blow air in faster than your piston engine swallows it to create boost.

Now what about at higher speeds? Stick your hand out the window at 60 mph and tell me that your leaf blower blows harder than that. Not likely. At higher speeds you might force air in faster than the engine normally draws at idle by using a scoop of some kind (hence the ram air systems on old muscle cars) and thus make a little more power. This still is not creating boost though. But with a little fan in the way you have a major restriction because the blades will not keep up to the air volume. So at high speeds the fan in your intake is also a restriction.

I don't see any time where these devices do anything positive. In my opinion the e-ram is nothing more than junk science trying to scam people out of their hard earned dollars and belongs in the pages of the National Enquirer. So don't waste your money buying these things and then thinking you need to buying bigger injectors or fuel controllers, etc to handle the boost because you aren't going to get any. If this crap actually worked you would see it on race cars or even mildly done street cars. I mean why would anyone in their right mind put an expensive turbo or supercharger on a car if this "electric tornado" cost less, weight less and actually did something?

i dont really think much would be accomplished with the blower idea either, but i had to point the above out

supergoat

I tried the e-ram. It works like it's supposed to. And contrary to popular belief it is NOT a restriction at low speeds. I'm not saying it's worth the $300+, but it worked like it said it would and gave a small, noticable power boost.

I think he was going on the assumption they would put this on some beater car they had just for a joke, and that the beater would have had pistons. Either that or it was a typo.

hey, chiconate, hows the leafblower project coming? I see good points and bad points to it, but am definetly interested if it actually does something... I Was going to try it on my rex, but never got around to it... plus the parents didn't want to part with our leafblower and i wasnt about to buy one... Good luck, let us know how its coming!

*lol* Guess I had a brain freeze. Actually putting it on a rotary would be even worse than a small displacement piston engine. Everyone knows our engines swallow a hell of a lot more air per cubic inch than a comparable sized piston engine.

I remember one time in auto shop (kinda like one time in band camp) our instructor did a demo of a turbo by putting one on the exhaust of an engine and and starting it up and revving it. You literally could not hold your hand above it; it would push it up.
That impressed me then, but what impresses me now is that I know that without load (as that turbo was operating) a stock TII turbo will NOT MAKE ENOUGH BOOST to even negate the vacuum the engine creates in the intake by drawing in air. I can't imagine how much air my turbo expells under load to fill my engines intake up to 10psi at 7000rpm! THINK ABOUT IT!!

NathanRX7

This is among my plans for my car once I get a job. Per your advice, I think I'll put the AFM or MAF (For what I understand, there is a difference, but I don't know which is which and what the difference is, so oh well.) on the intake side of the blower to avoid the problem you had. I'm pretty confident that I can make this or something similar work. It's still in the planning stages.

Jef Card is going to make me a sticker for the back of my car that says "Supercharged by a Briggs & Strattor Leaf Blower," but of course I probably wouldn't put it on because I don't like stickers.

Let me know if you have any ideas.

SoloRacer

Name the good points.

skibum9199

So maybe 10 leaf blowers, all outputs coming together? Thats gotta be good for something...


~Jesse


i know, i know...

skibum9199

Good point:

leaf blower $70

turbo kit $1500 + ...?


Jesse

NathanRX7

My point exactly. I am a poor college student, and I want my car to be faster. I am quite sure that adding a turbo would make a lot more power than adding a leaf blower, but I just do not have the money to do that right now. If I can get 3 or 4 PSI from a leaf blower, I would be thrilled. Maybe I can, maybe I can't. Some of you are sure that it won't work, but I think I'll try it anyway. If it doesn't work, you can laugh at me. If it works, I'll ask you what your forced induction cost you. Wish me luck for now, and tell me you told me so if and when it doesn't work. Thanks.

Leaf Blower= Loss of Power

Turbo Kit= BIg Power Gain

Why not save your money and your time and pop a turbo on, or a real supercharger. Sure it's more money than a leaf blower, but that's cause it's NOT a leaf blower.

SoloRacer

Money spent on leaf blower to get performance gain - $70.00

Money spent on plastic intercooler to get performance gain - ???????

Money spent on big BOV to get performance gain - ??????

Money spent on racing stickers and neon lights to get performance gain - ?????

Money spent on large tips for exhaust to get performance gain - ??????

Money saved and then spent on porting the rotary for an actual performance gain - Priceless

Money spent removing the catalytic convertors for an actual performance gain - Priceless

Money saved and then spent on Turbo Kit that actually makes power and puts huge grin on face - Priceless


I can think of a million an one ways you could spend your money that would have been better off rolled and smoked than spent on useless items. It always baffles me why guys who have little money to begin with are so willing to throw it away on useless stuff just because it was cheap. I would think if money was tight you would hold onto it and make sure you spent it on things you knew were going to make a difference. If you had lots of money to burn then great, go ahead and blow it experimenting with different things. But if you are short of cash look for things that have been proven to work before laying out the dough.

My suggestion is that if you want turbo power you should sell your N/A and get a T2. It will cost you less in the long run.

TriangleMan

Ok guys, sorry to bust your bubbles, but you will get zero psi from a leaf blower. let me tell you why. no matter how fast that air blows in, you can only cram so much air into the chambers. i know you all know that a turbo or supercharger COMPRESSES air via mechanical means, and then that compressed air is compressed further to make bigger explosion, more power. a leaf blower is only going to blow the air, it will not compress it. it will keep your engine from getting starved for air, but it will not give you boost, not .0001 psi.

Icemark

I agree with TriangleMan. Besides the intake speed almost is supersonic at 6000 rpm... that leaf blower is not gonna keep up with that.

skibum9199

Wow, i didnt realize that the air speed was going that fast at high rpm... thats pretty damn fast. Even so, supergoat got SOME small amount of increase from his e-ram, so why not try it? Actually, i think the price would be about zero since my garage, like many others, is crammed with useless things, like 3 or 4 shop vacs. I say use one of those instead of a blower. Money wasted, 0. Time wasted, maybe a lot, but hey... I don't think were looking to give an na turbo performance, just a little extra at WOT or whatever.. Its not really worth arguing over til someone actually does it and gets some results sooo..

Is there any CFM rating on the leaf blower. If it is blowing like 600 CFM or more, it is blowing more air than the engine can suck it, so it might actually make a difference. If it flows more like 450 CFM or so, then you aren't going to be making a difference. The problem would be that you would need a power inverter that could supply 1500 watts or more. The stock alternator could not keep up with this. 1500 watts would require about a 125 amp alternator just to keep up. Now if it is only in short bursts, then your battery could supply the demand, but if it were used a lot, then you would drain your battery and also burn out your alternator. Also, the most powerful electric blower I could find on the web was rated at 480 CFM, which might make a difference, but not much I don't think. Plus a heavy duty power inverter capable of 1500 watts would not be cheap. It is probably more trouble than it is worth.

What would be more interesting is a gas powered blower under the hood.

Place your hand over the air intake at idle. Not too long, though
Feel it suck? Now imagine how much it sucks when its at high rpm.
I have serious doubts that any leaf blower could provide such high airflow.
