hairdryer...lol

[Reed]

i cant wait to go to a car show and see some kid with a civic and individual throttle bodies with a hairdryer on each one. i dont know if i would laugh, cry, or just not be able to talk for a while.

[CBFryman]

Though i do live in the US, please keep things Metric... IMO the US is long due for a measurement change. after going through chem. 1 i confuse friends while tlaking in kelvin heat measurements and all that good stuff.... anyway. 600cfm? are you sure? thats alot of air.

[Sluttypatton]

600 CFM would be around 283 liters per second. Whether or not these figures are accurate, I have no idea but they seem a little unrealistic, however flow isn't going to help you without pressure. If the air isn't pressurised you won't be able to fit much more air into the cylinders and you won't create much more power.

*EDIT* - Upon researching, I have found that a typical hairdryer puts out at least 600cfm. Remember, I'm looking for FLOW, NOT pressure.

You can't do that without compressing the air, and anyone that have used a handpump to fill your bicycles tires with air knows that the higher the pressure gets the harder it is to pump the air.

lol...fuck it...just fuck it. These forums are full of nothing but a bunch of edotistical mechanics. If it's not their way it's not right. There is NO fucking encouragement on these boards for people to go out on their on and try things, then come back and report how it went.
I know how the responses are gonna go...I've seen tons of times before: "We just know what works and what doesn't, so we try to save you time." "No need to get pissed off cause you were proven wrong."
I don't get pissed off when proven wrong, I admit defeat, but you people dont even fucking listen or give half a shit. Would any of you care that I custom made a CAI for my Escort, out of a Pringles can? I'll probably get laughed at for that one, but you know what? It WORKS! There is no CAI made for the 2.0L SPI, only some crap short ram. An intake is an intake, regardless of what it is made out of, but do people care? fuck no, it has to be name brand.
Do electric s/c's work? I could feel the difference. I got one on a free trial, to see how well they actually did work....I felt a HUGE difference. On a little 4-banger, anything more is good. I can't remember the name off the top of my head, but its in a thread in the last 10 pages or so of this forum.
Fuck it. These forums suck ass, all egotistical an shit. I'll do my own shit, think up my own ideas, and say fuck everyone else...it's helped for the past 3 years, why wouldn't it work now.

[CBFryman]

WOAH WOAH WOAH, none of that. we are just telling you what from our calulations will help out. it wont really harm it. GOOSEFRABA

as for the statement about only boost will help the enigne. Flow is 100% more important than boost. if his hair dryer really does flow more than the enigne can supply then there will be a small pressure boost (untill the impeller in the HD cant push any more) and the engine wont have to suck its own air. resulting in a nice HP boost. not like boost (which in order to boost you must cheate more air flow than the engine can handle but anyway) which supplys more air than the engine can handle resulting in lots of extra oxygen. FLOW IS VERY IMPORTANT!!

i say try it. but dont expect more than 0.1bar boost if that. so no need to guage.
but be aware of power inverter costs and my reccomendation an extra battery and isolation kit...

[Sluttypatton]

Please, by all means go ahead and try it, if it works I would be more than happy to eat my words.

Might keep in mind that the HP your loseing to the alternator prolly exceeds what you would gain by using a hairdryer. If you really want to make your 'scort to go realy fast, I suggest pushing it off a really high cliff. If that seems too extreme however you could always get a bunch of hampsters, hampster wheels, and some Duct tape and go wild.

P.S. I hope you took the Pringles out of the can first, I forgot to do that when I was working on my 90' accord and now it smells like vinegar and salt everywhere I go.

P.S.S. Good for you! Every modding community needs people willing to find the cheepest solutions possible for problems to keep all those big companies in check. I say good Jorb!

the hairdryer wasnt exactly intened to put on 300 extra horse power like alot of people seem to be forgeting here... little 4 banger? more is more. anythint hat can help and is cheap, is some great shit.. instead of spending money for a power inverter... run down to princess auto and pick up a nice little DC motor.. far as the alternator taking horsepower? its going to spin, and produce power regardless....
yall idiots.. i came to these forms thinking i might be able to learn somethin but all you guys seem to do is shoot people and there ideas down.. (well not all of you, somegood guys ont histhing.) Escorts rule.

[CBFryman]

actually the altinator only supplies as much power as is needed at the time. so if 10amps are needed 10amps are supplied, if 100amps are needed 100amps are supplied. the more amps needed the more torque it takes to turn the altinator. if the hair dryer motor makes maximum flow at 600w (alot of the wattage is reduced now that it has no heat coil) all things 100% efficent (ehh...not) it will pull about 50amps 12v DC and about 43 on 14v (around the average car voltage) which is why i reccomended an extra battery and a battery isolator and switch, so he can run it untill the voltage drops down too much, kill the hair dryer, letthe battery's recharge and then flip them back on... or use it for raceing/passing/extra hp needed situations.

if only automanufactures where smart enough to run an altinator off of exaust flow...

[Jet-Lee]

got the hairdryer, switch, and some wiring. Gonna get some more wiring, and a relay, then I'll be all set to go. Will let ya guys know what happens.

To let you know how its gonna be setup. It will be pulling from my CAI (custom). It will be using a 2p3t switch. One setting is off...completely. Throw the switch one way and the relay gets tripped when my runner control is activated at 3000 rpm. Throw the switch the opposite direction, and it's just on. I will let you guys know how it goes and what happens. Will probably relocate my CAI while I'm at it...

[theflinger]

glad to see you're doing something
reality > theory

But I don't really think that anyone was trying to shut you down, or anything, they were just trying to help :/

[PeanutM&MsRgood4u]

You have no idea how cool an hairdryer hooked up to your intake would look if it was covered in LEDs. Serious dude, do it!

Smartest thing stated in this thread. Thats why bigger turbos make more power at lower pressure. If this wasn't the case, then why are turbos upgraded? Why can't a SR20 just use the stock T25? Because it can only flow about 28lbs(enough to support about 250whp). That just so happens to be at 15psi.

As for the hairdryer.LMFAO I used it to see how well my intercooler worked.lol It works pretty well too.

But then insted of drawing power off the engine wouldn't you be increasing the resistance of air flow through the engine, resulting in power loss? I mean no matter how much you want to, power isn't made, its converted. In this case you would be converting the mechanical energy the engine SHOULD be producing into electrical energy. I guess what it really comes down to is if exhaust is more efficient than straight off the block.
