1000% agree. If one would take a look at the blades on that uint it wouldn't compress shyt.. its basicly a freakin highpowered ducted fun that blows hot air..

NO GOOD..

 

i will pwn all with this electric supercharger vacuum cleaner fan mod!

 

Your reply did not response to the "many factors" that you quoted on my post.

Where did you get the formula "Engine CFM + Fan CFM = Engine CFM"?

I have come to that wildweasel site when I first searched about this topic and read the whole post word by word. Yes, they are talking about real physics there. It makes perfect sense how boost is created. However, I am not arguing about these little electric supercharges making boost. My point is they can bring more air into the intake and also make the air flow easier. If your theory is that more air flowing in the the air intake does not make any gain in the power then I have nothing to say.

 

I didn't feel the need to correct something that was 100% wrong--i.e., it contained no merit at all, therefore needed to be disregarded, not corrected.

Here, I'll fix it for you, since you seem to be a bit obtuse...

Engine CFM + Fan CFM - Fan-Induced Pressure Restriction = LOWER Engine Pressure (than stock)

BTW, this isn't a real formula. It's meant to illustrate a point. Read it a few times if you don't get it the first go-round.

You cannot simply blow more air into a system that's already set up for a given air flow. To add more air into the system, you need to increase the PRESSURE of the air intact (e.g., with an air COMPRESSOR). If you can't get this basic concept, then explaining this to you further is an exercise in futility.

Good.

Does this work on Evos?

 

Someone please close this bullsh!t thread allready......thank you.

 

is this for realz?

i cant believe this was even posted to begin with...

 

yeah but you'll need four of 'em

 

350Zed: I don't see anything not correct with the term "many factors" in my illustrated equation. Everybody who knows a thing or two about combustion engine will know the fact that power gain depends on many factors not only one or two. Thus, there is nothing wrong to say:
power gain = Fuel mixture (amount of air (oxygen)*amount of fuel) + many other factors
If you can't explain what "many factors" means then I will go ahead and tell you what they partially are.
- Other than fuel mixture, timing plays an extremely important role in making more power. What is timing? It includes ignition timing and valve timing (controlled by cams).
- Other than timing, the ease of gas flow also effects the power gain or realistically, power that is released. The easier the air getting to the intake chamber (that is why people have aluminum intake pipes, ported throttle body, ported intake), the easier fuel mixture flow into the combustion chamber and exhaust gas blown out of the combustion chamber (that is why people upgrade their valve systems); the more power you gain.
- The same concept stands for exhaust such as upgraded headers, high flow catalytic converter or flow through CAT, bigger diameter exhaust pipe, less restrictive muffler,...

Those are just partially of "many factors" that I mentioned above.

You did not make any sense by illustrating engine CFM vs fan CFM. It only makes sense when the fan blow LESS air CFM than the engine sucks in. Please stop saying about making positive pressure in the engine intake because our engine are N/A which means the pressure in the air intake is ALWAYS negative or close to 0 (equal to atmosphere pressure) at WOT. I will say it one more time here, these fans work in the mean that it allows the air flow into the air intake easier not in the mean that it will create 1psi of boost or whatever.

If you believe that more air flowing into the air intake does not change the engine performance in any aspect, then you have no idea about combustion engine. K&N and other high flow air filter manufacturers definitely will go out of business if what you are believing in is true.

PS. I will stop at this point since I don't feel there is a high probability that you understand what we are discussing about. I come here to learn something more about cars, what I have been doing for 6 years, not for arguing about mislead information.

 

if only all this debate was concerning turbos/SCs and correlating flow maps with engine cfm outputs......its all over a stoopid blower motor. lol

 

This is the ONLY one that EVER worked and you can't run it more than about a minute without running the EXTRA batteries down:

A cheap way of doing a mild supercharging effect is to ram the air into the engine with forward facing air scoops like in the pictures below. The denser and cooler the air the better it is for producing power with the proper fuel/air ratio. On the G35 coupe it has a air scoop which also help the engine breathe easier at higher speeds.

But if you really want to do it properly you do get what you pay for, exhaust driven turbos are unbeatable for performance and reliability and they have been used for many years and have proven their worth.




I actually did a set up like this on a 1980 prelude with a set of scoops under the front bumper which fed into a modified air filter housing, you really could feel the difference once you were going over 60 KPH and it was even better at 120 KPH. It was removed for the winter because the carburetor would freeze up because I disconnected and closed off the heat riser pipes.. Yeh, Fun stuff

 

Again, I'll simplify this for you...

High-flow air intake manufacturers work by de-restricting air intakes. That's one of the two only ways to get more air into the system. The other way is to keep the system's intake rate constant, but compress the intake charge so there's more oxygen per intake volume.

Your electric fan does neither.

I don't need to dis-prove your nonsense, and I've done more than enough to show you how intake systems really work. If you don't believe me, look at all the other members here ridiculing you for spreading lies.

I am going to wait on these vacuum powered superchargers!! Dyson FTW

 

In theory I agree that the fans can help with power if you can jam enough air into the intake under pressure using a strong enough powerful fan, The big problem is where does the power come from to power the fans, exhaust gas turbos are efficient because they don't add any additional loads to the engine, turbos add power without sacrificing fuel economy.
A supercharger isn't as friendly to fuel economy because it draws its power from the engine (less efficiency) but for in applications where fuel economy isn't an issue and max HP is wanted supercharging is a good way to go.
Your electric "turbo" draws power from the alternator which has to draw power away from the engine to make the electricity. You could have a very long extension cord to power it or you could put under the hood a very large alternator which can keep up with the power demands of a fan capable of pressurizing the intake air . But then you will be doing what a supercharger does but much less efficiently, maybe so inefficiently that total HP gains would be minimal and at much worse fuel economy.
I would forget about the electric "turbo" and toss the idea into the garbage bin with the 100 MPG carburetor and spend your time on the more noble cause of convincing your wife (or girl friend) that she should allow you to spend some money fitting the G35 with twin turbos.
