WHat's up with those bolt on "mini turbo"? Does anyone have one? What does it do and how well does it work. From what I have researched, you attached this "mini turbo" to your aftermarket air intake tube and make sure that it doesn't move. Then you hook it up to your battery. There's a toggle switch involved. It suppose to kick out around 460rpm forcing air into your engine. Sounds like a poor mans turbo or people who want the most out of their engine but can't afford a name brand turbo. Does anyone know if it increases hp and heat under your hood? Where can I get some results?

It's a sham. All they do is put a fan in a tube, make you attach it to your intake, and make you think it's improving performance. It's forcing air into your intake about as much as having a fan blow on the intake would. All that for $200 and wasting battery power.

If you want forced induction, get a supercharger or turbo specifically for your Civic, along with the essential parts. Failing that, or if you're just too poor to afford that kinda stuff, go hit the N2O bottle. Just please, please, PLEASE don't get that accursed piece of junk. You'll be ripping yourself off. Only thing that modified aquarium fan is designed for is blowing smoke up your [IMG]i/expressions/moon.gif[/IMG]

Always remember to trust your instincts. When something sounds too good to be true, 99% of the time it probably is.

do they make superchargers for our cars???
i would love one of those over a turbo

no supercharger....probably never will be.

turbo = custom job so far

tornado is totally different

as to buying a fan, and putting it on yoru intake, everyoen says its BS, but the fact is, if you cna actually pressurize yoru air, you WILL see a performance gain!

will you get a fan that cna put out pressurized air on ebay for $20? nope. But i decided I wanted a new toy anyways.

you can totally get $20 a fun out of a fan. I still have plans to use it in my car, but if your looking for performance gains, your not gonna get any.

I bought it hoping it owuld make my engine sound more rice, to impress all teh locals ehre, but i wasnt even lucky in that department.

all waste air gets blown OUT the intake, after 3000 rpm or so, the engine draws more air than teh fan can produce, I assume itll bog down teh engine trying to spin those blades. might charge the battery tho [IMG]i/expressions/face-icon-small-wink.gif[/IMG]

so, why trust these ppl who were too quick to judge without getting to try it themselves?

bottom line:

performance: zero
engine sound: zero
fun toy to play with? you bet!
educational toy to play with? you bet!
worth my $20 off ebay? you bet!
sitting in my garage collecing dust righ tnow? you bet!
got $20 of value from it? you bet!
still will get more value from it in the future? you bet!

well you can always make use of that thing...even though it sucks up 3 amps of current...put it by the inner fender (where an injen cai filter will be located) so cold air is forced into the engine bay...this will be great for cars that have sri...or put it on the inside of the car and put a car freshner infront of it...thats somewhat what i did with some extra small fans i got from work before...my car smells sweet whenever i want it to...

the issue wasnt pressurizing your engine at 4 psi, but the fact is, if you can pressurize the air, you WILL get more power. But why does it have to be 50 horse? why not find an electronics motor that cna pressurize at 1 or 2 psi, thats still good for 8-16 horse, which is far more than any of you will ever see with i/h/e......

why cant you find a 12 volt motor that will actually put out real pressure? ever hear of an industrial vaccum cleaner? not 12 volts, but you get the idea, such motors DO actaully exist....

just not for $20 on ebay, is all. your all right, the ebay deals ARE a scam, but why do you all talk as if you have any idea? none of you ahve tried it, you just assume that since its too good to be true, teh idea as a whole must be bad, and anyone who thinks they get real power form it is an idiot. The REAL fact is, that thermodynamics dont lie, and if you all found a *real* turbocharger built at teh same quality as these fans here, added no pressure, gave you no power, but sold on eby for $200, i bet you would all eat them up. they are a *real* turbo, right?

pressure makes power, not technology or lack of stadardized technology.

just thought of something interesting, what abotu electric cars? they make a 2 seater now that can go 0-60 in under 4 seconds, and outperform ANY civic in autoX. fully electric. The issue isnt whether its worth doing, whether its long term effective, why "not eveyone is doing it", the issue is whether or not it CAN be done, which is a definite yes.

Someone needs to introduce you to fluid dynamics. You can NOT compress air with a fan. there is a BIG difference between PUSHING or PULLING air and COMPRESSING it.

 
Rep Power: 337

nope, fluid dynamics is a 4th year college course, im not there till next year [IMG]i/expressions/face-icon-small-wink.gif[/IMG]

but please, i would like to know the difference between say the stator of an airplane engine and a fan blade. seems to me if you put enough torque on that fan bade in house, you will get some sort of pressure rather than backflow? educate me

are you saying its impossible to inflate a ballon to the smallest degree with a fan? (serious question, ive never tried it) because that certainly takes pressure, even if only small amounts of, it, and that seems to me like it would be completely possible, and that would also prove that a fan could in fact pressurize air.

but no, you are right, i dont know fluid dynamics, i didnt speak of the possibility of the fan doing it, i was merely stating that IF a fan COULD pressurize the air, you WOULD see power benefits.

but im truly interested in the fluid dynamics of these fan systems and why its impossible for them to prssurize any air, even that in a balloon.

All dynamic compressors are inheriently high-speed devices. They obtain compression by accelerating the gas to a high velocity and then slowing it down by diffusion. Diffusion converts velocity energy into pressure energy by slowing down the gas without turbulence. a turbocharger is a dynamic compressor, and turbine engines use them to compress gas.

Simple answer:
a fan CANNOT compress air... because it works by creating a low pressure area behind the fan blades.

you either need a positive displacement pump (roots blower, oil pump, etc...) or a diffuser (housing on the turbo) to compress air.
to compress the air on a turbo, you must slow down the air in the diffuser... as velocity decreases, pressure increases. There is no way you can do this with a fan.

so... there are basically three reasons that a fan cannot compress the intake charge:
1) it is a (comparatively) low speed devices... 5k RPM vs 100k
2) It has the wrong compressor design, and is therefore horribly inefficient
3) there is no diffusion

1 means it can't impart enough delta-V into the intake charge to make any kind of compression, even if there WAS diffusion... think a turbo makes any boost at 5k RPM? It probably turns faster than that at idle

and

2 means; instead of compressor think impeller (fan)

Im sure you know what diffusion is, so no need to explain 3.

Long answer: http://scienceworld.wolfram.com/phys...oullisLaw.html

as for an aircraft turbine engine... its fairly easy to see how it differs from a "fan":

Rep Power: 337

and its gonna take some work to counter, especially with no formal training in fluid dynamics, but ive got 3 professors who already say fans CAN pressurise air, in fact, i just need to get them to explain it to me properly during office hours.

but i was wondering, that website on bernouliis principle was really informative, but when it came to ACTUALLY proving whether or not a fan can pressurize air or not, i became confused, because in order to prove teh linear relationship worked, an incompressible flow had to be ASSUMED, not proven.

makes perfect sense, seeing as the gradient would look like a flat plane, but it only works if you assume its incompressible, which was a given, not solved. If i go back to one of the original equasions, pu du = -dP, it seems that if i were to change the velocity greatly, i COULD get the pressure to chage a bit, along a "streamline".

thats where i get hung up, could you define a streamline for me? would an intake pipe be considered a streamline? where I could increase the velocity of air to teh point of a presure increase?

my last question is can I hook a fan up to a baloon and inflate it a little? is it possible? a baloon we could say is a small pressure vessel, and seems to be quite possible for something to blow at such a velocity as to inflate it, agsaint atmosphereic pressure.

my REAL final question is have you ever done reverse vacuum bagging? I had to do a bit of it while a glassed my rear deck shut. I did it a ghetto style, using a shopvac and plastic bags. During testing, we had problems with teh test bags because they would literally pop. after inflating, they would expand, untill the plastic film underwent catastrophic failure. a bag expanding liek that would take quite a bit of pressure. And a vaccuum is merely a type of fan, easily adaptable for a car's intake. What about that for the possibility of pressure?

plz dont use current draw as an infeasibility, im well aware of jsut how much power such high flow fans actually take, but the question Im asking isnt whether the $20 ebay fans work, we all know they dont, its if its POSSIBLE?

 
Rep Power: 337

nevermind, i found out the reason we have a discrpancy.

the answer as I see it now is that the reason you say its impossible and I say its possible is because we have different definitions of the word "fan"

I say its any sort of anything you can put on a 12 volt motor that will spin and push air. That, by defniition HAS to be able to pressurize air, cause weve all seen a hovercraft in action!

If you define a fan as a prop connected to a spinning shatf of a 12 volt motor, I would be more ready to believe you, but I should ask, have you ever seen a prop plane in action? theyd fall right out of the sky if they couldnt pressurize air!

so am i right, its just our definitions of fans that cause the discrepancy in possibilities? is it still IMPOSSIBLE to pressurize air with any sort of device that fits the description of "some device that is spun by some sort of 12V motor to blow air" or a similar definition....
