Off topic for a moment, but sadly the camera messed up the pics for the suspension replacement so I won't be posting them.

I know some people tend to disagree with this method a little bit, but... Here's a little something I'm rigging up in my intake. Couple of Nidec fans I got for really cheap. The lowest figures I have for them they will flow 500 cfm total at 1/4-1/2 psi, highest figures I have are 700 cfm total with 1 psi. I'm believing the 500 at 1/4 to 1/2 the most just to err on the lower side.

I'm going to wire a micro switch and relay to the throttle so that when I'm at idle they will be off and when I step on the pedal they will kick on. Also going to wire a master switch inside the car so that I can have the option of driving with or without them on.

I've never gone for the whole electric supercharger thing...but hey, 500+ cfm aint bad at all for one of those little fans. I'm always open for new ideas... I'd be interested to see if it helps at all. How quick do those fans 'spool'?

 

I wouldn't classify anything electric as a supercharger, but in actuallity, I guess that's the category that they'd fit in. I picked them up a long time ago for about $5 apiece and they've been sitting since. They're pretty quick on the spool up. Haven't timed them, but somewhere under half a second. They spin at 3500 rpm.

 

thats pretty crazy, keep us updated on any gains you notice. you should notice something from it.

 

I think it could work, bilge blowers would be better, but hey, for 5 bux you can't go wrong. it can't hurt the motor (as long as you use a filter between the fan and intake).

 

Don't get me wrong here, I'm all for trying out new things, but I seriously doubt that you will be seeing any kind of difference from them. With your max number of 1 psi, you will only get a reduction from ambient air pressure (~29 in.), so you are now looking at 28 in at WOT. I can do that by driving the car when a storm is coming in.

Right on for trying something new, but don't get your hopes up...and for $5 and some creativity, it should be fun anyway just to screw with something.

 

Why would you ever want to not have them on?? Just curious

 

I'm definitly not expecting miracles and not hoping for much, but any little bit helps. If you notice carefully in the picture that's duct tape holding them to the snorkel. I've had enough of doing my homework for this week so I decided to play with the car. I think the girl at radio shack is starting to wonder about me coming in so often to pick up small electrical components.

Yes, K&N's.

 

Actual testing as to whether they do much of anything. And if they do work, when I'm just cruising and don't need the extra. Course, who knows...maybe they won't do anything cept for increase MPG on the highway and hurt MPG around town. Never hurts to have a quick shutoff on something experimental.

 

As I said, with mine, it did actually force more air into the engine at idle.. enough to affect idle rpm by about 100... so, hey. there are gains to be had. Maybe not huge gains, but for 10 bucks, who's counting. Good luck with that.. make sure your air intake system is sealed REAL tight, or you'll vent whatever boost you would generate to atmosphere.

 

i see that one of your locations is in florida....when and what part? if you're near me, we could test it on my car, see if it does anything on it!

 

Forgot my drill at school when I went to visit my girlfriend/now fiance (yeah, popped the question this weekend and 10 minutes later thought of how much less money I'm going to have to spend on my camaro ). So, fans aren't hooked up yet and next chance to do it looks like 2 weekends from now...provided nothing goes majorly wrong with the Saab tune-up I'm doing then. Same with the rest of the stuff sitting in the trunk of my car.

AM91-
Sent you a PM. Also, what kind of timing do you have? I'm assuming you're running nothing but 93 octane or higher.

 

Congrats man....you're one brave soul. Good luck. Let us know how the little project goes...... Hell if you're ever down in this area for some strange reason, we can hook my G-Tech up and do a little testing.

 

i'm running about a 12* advance. 93 octane all the time unless i put some 114 in it!

 

I just have a hard time believing that, those fans can flow enough to produce any boost at above 1500-2000 rpm.

I mean have you looked at the insides of a turbo. The fins are a lot larger and they spin at 20000-50000 rpm .

I am just speculating, but still..........please do tell us how this works out.

 

Yes, I have looked at the inside of a turbo, I have 4 of them torn apart here. Remember that with a turbo you're talking about 8-25psi boost. These are on the order of only 1/4-1.

 

Congrats!! Just don't let your car go to sht! Yesterday was the first time my car saw a vacuum in years...

And let us know how the testing goes. I have a feeling that the engine's pull will spin the fans faster then they'll spin themselves, but it'll be great to know the test results! Do those fans have a feedback as to what RPM they're running at? It'd be interesting to pop a reader on there to see if the fans run faster/slower/etc...

 

yup.

the motor will pull the fans faster.. eventually they'll reach the break down point, a fin or two will come off, and that'll be that.


id explain how a FAN cannot create boost like a impeller, or how it will just become a spinning restriction..

but honestly, i think this is the same dude i already explained this to at www.3rdgen.org ..... and he has filters between them for when they blow apart, so i'll just sit back and watch.



athough i wouldnt use K&Ns... id use paper filters... paper ones usually have a stronger steel mesh on the underside... you'll want that to keep the shrapnel out.

 

 

Only in America.

Actually I think the idea will work at low RPM but might create a restriction as more air is demanded by the engine. Anything is worth a try though. If if fails you can just do what every other inventer does (prototype).

 

lmao hahahahahahahah


This idea is not good, it's exactly as Mr. Dude says, and it will be a restriction.

 

Everyone's entitled to their opinion.

Managed to free up my afternoon so I got it wired up today and was able to take it on a 15mph tour around the post to make sure everything was working how it is supposed to. Post police are all over the place today for some reason. I noticed a better throttle response, but at that slow a speed it's impossible to notice anything else.

 

:werd:

 

seriously though.

if you want more part throttle power, you can remove the sheetmetal restriction in the throttle body.

it'll make it idle a lil higher (thats why they didnt do it from the factory) but she'll have tons more power... probly more then you want going around town.

 

what does this look like, i have no clue what your talking about but would like to know.

 

I might try that. Don't know yet.

No, I'm not the same dude you explained it to on 3rdgen.org. Well, for the total of $10 that I spent a long time before this idea came up, it's worth a try. There are many things that give more power in different places...just trying an idea. Out of curiosity...do you know what rpm's I run my car at? What kind of driving I do? Where I'm looking for the extra little bit of performance? Is trying an idea where things seem to line up kinda close that bad an idea? Truthfully though, thanks for mentioning the concern about the fans blowing apart. I do know about what you are talking about and I did take that into consideration, however it's good to make sure all the bases are covered.

Checking the rpms is part of the testing I'm planning on doing. I can borrow a few things from a project I did in the fall to hook up and check the rpm's.

 

ok, freeze frame! whats this steel mesh = more power thing? how much higher idle? this will reduce fuel economy wont it?

 

yes. as a matter of fact i do. your overall range is from idle to redline. and both experiance and simple math based on your gear ratios and tire size tell me about where your RPMs are at any speed in any gear.
unless your a complete moron that does 70mph in first gear or somthing queer like that.


well, being that its not a turbo V6, it doesnt have any power adders, and its not a tweeked out race motor, im going to have to say, slow. now you could accept that, and id respect you for it, or you could argue that your 170hp smogger V6 is badass. i dont have a problem with V6 guys, as long as they dont have their heads in the clouds... same with L03 V8 guys..

i hope its WOT high RPM driving though.... post pics of the fins embedded in the paper filter. it'll serve as a nice warning to the next kid that trys this... i honestly feel bad for them since most of the time, the fans get eaten by the motor and the valves get fugged (or worse)


trying out new stuff isnt a bad idea... but not all ideas that are "kinda close" are good ideas.




if they have the regular PC out RPM signal, theres several ways to log it.
if you're good at electronics, you could use a simple transistor circuit and log the data thru a extra fan connector on a motherboard, and then use some generic motherboard monitoring software.





i didnt say more power.
most flat paper filters have this strong steel mesh backing to keep the filter together.

when his fan blows apart, the stronger mesh has a better chance of catching the plastic pieces then the thinner K&N stuff.



you have to realize, hes NOT the first one to do this... matter of fact, hundreds of people have attempted it.. alot fragged their motors.... do a search for electric supercharger on any respectable car board, and you'll see what i mean.

 

oh, as for the sheetmetal in the intake mod.

think about it.


its the butterfly valve in the throttlebody.


the trick to having more power at part throttle is..................... open the throttle more.

 

Wow; I wonder how long any motor would last without that butterfly valve. I also wonder if it'd be hard to start, since the motor would have 100% airflow but the TPS was telling the engine otherwise. Nobody try this at home! I don't need to know that bad!!

 

That would be easy to test. Start the car and stick a fan in front of the MAF and see how fast it spins.

I do know a fan that has the CFM but not sure about pressure. They do well over 2000 CFM. I know cause them triangle 2000CFM air cleaners will bog it down. But its an AC fan.

Though compare to a big stereo system the converter for the AC fan wouldn't be that much more / maybe less.

But one your that far I know a place where you can get electric leaf blowers for $9.99 about $20 shipped.

Oh and if I were you, put MrDude_1 on ignore. Making a point is important but do it in a nice friendly way. Anyone who bashes just to bash gets ignored. Some people would die first from being nice than not breathing. Help peple, give an oponion but do it nicely.

Alright, finally got a chance to actually take my car for a drive to Walmart. Noticeable gains on the low end, can definitly feel it in the seat of the pants. No tests for gains on the high end...never get up there anyway cept on rare occassion. Maybe I'll actually have to drive 15 minutes over the the 1/8 mile strip and get some numbers one of these weekends.

 

i know im a ******* somtimes.

athough i dont think anything i said is a direct bash.

re-read my first post... then tell me if that isnt sound advice......



other then my lil tease about removing the butterfly for more performance, it was all technical. in a azsholish way perhaps, but technical none the less. i didnt attack him personally and call him a moron or anything... just stated why it wouldnt work, and whats probly going to happen.

 

lol, didnt even think of the TPS... athough it probly wouldnt matter... the MAP would see the pressure and correct for it... probly throw a TPS code.

 

The computer would probably notice that there is a lot more flow thru there via MAP/MAF(depending on system) and think that the TPS is bad. It'll set a code for TPS then substitute a value depending on the MAP/MAF and RPM. The motor would then rev all the way up to the rev limiter and bounce around there until you shut it off. If you don't have a rev limiter, you'll quickly find out where your true mechanical redline is.

 

Ha ha, almost did that the other night! 6800 rpms and counting. Powerslides with no rev limiter are no good. All she did was **** some oil in my driveway overnight, thank ***.

I'd love to see numbers on the little electric fan thing...just for the hell of it. I doubt any real gains but hey....you never REALLY know anything until ya try it for yourself.

 

There's a noticeable difference, small, but noticeable. You're right, no really big gains. I'm curious about numbers too. Every little bit helps.
