I say we all donate 10 bucks to Tom or whoever owns this site, and then let them do a couple dyno runs on the thing, and then make this a sticky. I got ten on it.

Somone set up a paypal account and lets do this.

Well if thet make it a sticky, then they might want to change the name of the thread.

And, thank you munkyv22.. makes sense.

also.. $10 does not sound bad. I'll just eat spagetti Os for a few days.. :0)
 
Come on, if the eRAM is so great, it's only $300, which is just a little more than what a decent intake costs. If the eRAM is what it says it can do, the gains should be more than a typical intake if it's forcing enough air into the engine to cause air compression.
Come on you believers. Step up to the plate and prove us all wrong.
That guy who did the test for eRAM probably had a bad Focus.
 
haha, I would rather spend less money and have something alot stronger.

I am a believer, just not in a 12V motor. I understand and do believe that the law of conservation of energy applys here. Thats why I believe that an electric motor run from 125V stands a hell of a much better chance at seeing gains than the eRam.
 
haha.. munky so mean.

But if you seriously have not tried it, then you seriously don't know.
However, I can clearly see how almost every person could find it hard to take it seriously or give it serious thought. But soon, we shall see.
 
Not meant to be mean, just thought it would be funny. :)

You have my serious support to give this a shot and see what it does.
 
The Turbonator doesnt work, everyone that says that it does and that the leaf blower works needs a lesson in engineering. That worked because they had no intake, that is why there was increased horsepower.

but on the video, the leafblower WAS the intake......if it wasn't compresing the air, they would have shown a loss of power on the dyno.

and to prove the air was being forced in, they sprayed it with juice....more gains...

leafblower works, just isn't practical.
 
Tim, you dont understand how forced induction works thats the thing, they were holding it close to the intake, it wasnt the intake though. If it wasnt compressing the air it would have shown a loss of power? What are you talking about? The leafblower cant compress the air. The juice was being sucked/blown in by the motor, it wasnt being forced in. I'm not yelling at you, I'm simply saying I know how it works.

-Ryan
 
I am a mechanical designer am, I know how things work, lol I just don't want to come across as a nerd. Anyway, it was compressing the air the same way the condenser coil/fan at your house makes cfm to move the air.

Anytime, air is being force thru a small diameter hose.....leaf blowers blow on avg. 215mph which somewhere around 500cfm depending on the attachment hose. Anyway, technically, the leaf blower, when fully attached to the end of the intake throttle body, WOULD be forcing the air in at a rate faster than can be taken in by the intake from them motors vaccum (or suction).........so, the extra air has nowhere to escape to, producing a "compression" effect......or psi.........it may not be much, but it is forcing more air into the motor than naturally taken in, so thats technically boost.

In mechanical duct, this is controlled by a vfd, or variable frequency drive.........
 
Timmay...

See, the major difference between Tim and AM. Tim is actually giving explanation to why it has possibility, instead of saying that’s not how it works or you do not understand.

What Tim is saying makes sense. Again reiterating, nobody (obviously) is expecting great things from this. Just something, if anything other than the engine going boom. But then again, everyone other then Tim and myself (and one other, I think dragon, sorry am too lazy right now to go back in the thread and look) thinks this will not do anything what-so-ever other than obstruct the airflow.

So how would I be risking my engine if a leaf blower won't do anything?
Cause unfortunately, you have said nothing to actually back up why it will not have a positive effect. And just like any modification, with improper planning, it can cause damage or improper operation so that point is valid with any performance modification.
 
Alright since your a mechinical engineer, I suppose you are calling the people at MSOE dumb and wrong, I know I am right because I went for a week long crash course in Automotive Engineering and they brought this up and showed up how it doesnt work. A fan, such as the one in your house, does not compress air, it pulls it through. A supercharger or turbo charger work kind of like that except they pull air in and compress it instead of just pulling it in like a fan. If you dont belive me ask any automotive engineer, but I wouldnt call me wrong when I have several Automotive Engineers telling me it doesnt work.

A fan, such as the one in your house, does not compress air, it pulls it through.

Cover the return air grilles and watch your motor burn up.......yes it pulls it thru, but the design of it makes it restrict right out the fan by means of either a 90 elbow usually and duct size drops..........it will go from 36X24 to maybe a 30X20-28x12.........etc....to maintain air velocity by means of constricting the area that the air is in.

Air can only be compressed when confined into an area smaller than the mass of the air.

A simple straw test, blow thru a straw.....thats what the intake does...(actually its the motor sucking air in)

then put your finger on the tip, then you are compressing air because it can't escape faster than you are adding more air.

Air that is compressed is tryign to find the easiest route to get out, with a turbo that route is the motor, because the psi (pressure of blowing into a straw) is greater than the area significantly.....

ie. airbags on cars, pressurize the air into the tank, open the valves, the air is always waiting for a way out.......so it escapes thru the opening in the valve to fill the bags when you hit the switch.........then its still under pressure even then, so open the valves on the bags......the air escapes out, lowering the airbag....


A supercharger or turbo charger work kind of like that except they pull air in and compress it instead of just pulling it in like a fan.
You are right but if you hold that turbocharger in the air, with nothing hooked to the motor, all you have is a fancy eRam (fan)...the problem with the eRam is that it doesn't make enough psi to make a whole lot of difference....I'm sure it does work, but not enough to make it practical because its not making that much psi.
 
I just realized I now have a soldier in there fightin for me. [hihi]
Thanks for the help Tim. [cheers]

My only other comment is this, who said anything about using a conventional house fan? When was the last time you used a leaf blower? I have been using then since I was 15, I am 23 now.. they have gotten a heck of alot smaller, alot stronger, and require much less power than they used to.

Question,
What is the air volume that an exhaust driven turbo delivers?
That way I can compare it to what the blowers have. The highest I have seen was about 550cfm at 230mph wind speed.
 
First off I'm talking about the "Turbonator" because that is what this thread is supposed to be about, that will not work. Second is that CFM does not matter unless it has the power to compress it, you can have 10000 CFM but that means nothing unless it can compress it. It will take a very strong electic motor to compress the kind of air we are talking about, it also has to be variable as per the rotation of the motor, kinda what Tim said before.

For the leaf blower, if you look at the video, he was holding it up to the intake, not inside of it. Something like that might be able to push .2 psi maximum. If you want an experiment, take a leaf blower and put your hand over the end, and do not let any air escape, that is pressure. Now that needs to be constant pressure and variable tot he engine speed. Now if you want to go to extreams, yes it will work but not with a hand-held leaf blower unless you have an industrial one the side of a small country. I showed this whole thing to a professor at MSOE and he started laughing at everyone.

-Ryan
 
AM, granted, topic went by by.

For the leaf blower,
Sorry if it seems like I am pushing this issue, but it just seems to make sense. I just can't accept no for an answer just because you spoke to some prof who said no. Unless he actually took apart and looked at the parts to see exactly why it would not work. So I took your advise and went to the Nobles, I only found one book dedicated to chargers on the shelf called Maximum Boost. And with all the basic principals, [scratch]

If it allows the flow of over 400 CFM and 2L engines only require 190 cfm at 6000 rpm (guestimation)... then the only problem would be the turbine impeller of the blower. Since it is designed to move air rather than reach and maintain compression. So what if the impeller were replaced with one that can reach and maintain compression?

I don't believe the BS that if it runs off electricity, then your taking away more power than your putting in. It's true if we were physically using the leaf-blower to help spin the engine itself, but its not. Instead we're blowing air into the engine, increasing the amount of oxygen going in. The general argument against running it off the electrical is that your converting from mechanical to electrical back to mechanical energy, which is true, you are, but this is where the mistake is made. People assume that's the end, in which case you can never get out as much power as you put in, but that's not the end, we're losing power to essentially "harvest" energy already stored in the oxygen, which will give us more energy than we had to put in, because it's already there; we didn't have to exert extra effort or energy to put it there. Conclusion: Electrical may not yield quite as high a gain as obvious methods, but it would probably be the simplest and cheapest.

[thankyou]
 
whats out there in the ways of gas powered leaf blowers?

then you wouldnt be expelling any additional energy, youd jsut have to worry about safely rigging it to turn on/off/throttle and fitting it and how safe it be to have that little bit of gasoline sitting in the leaf blower

not the easiest thing but it sounds interesting enough, like a fun little research project if i didnt have better things to do
 
You are correct, glad you did some reasearch. About the professor thing, I would call him some professor, he knows more about automotive engineering then you could ever dream to. I dont think you appericate an engineer and you cant because you dont understand the physics and science of it. Back to the point, the propeller does not only have to maintain it, it must also adjust for it. You cannot constantly boost at the same pressure or you will blow the motor. Hentz why a Turbo and Supercharger always has some sort of blow through, ie a blow off valve or by pass. More to come but I am going to bed.

-Ryan
 
^^^You are right, the eRam only kicks on at WOT and not for more than 20 seconds I think it says on the website. And yes, it would work, but it needs to be a bit stronger to make it worth the 300.00 dollars.
