all right so i fell for it, i bought an electric "supercharger" off of ebay...in my attempts to try and have a "fast" n/a. now i know what your thinking, this is some 16 yr old who fell for another ebay piece of crap...BUT im not 16 and it works, atleast i think it does. all it does is blow air into teh intake elbow right behind the filter at the flip of an included switch. i can tell it has more low end power than before and the engine runs fine. since im not an expert and i should have asked you guys before i bought it (i apologize for my stunt.) but until i get my gtech back i cant give any real data besides what i think. but can anyone think of any reasons it would not be good for the car?...i cant think of anything besides it perhaps messing up the air flow meter readings and making the car run too rich. thanks

 

10 page thread guarenteed. And gtechs suck. Go to some where with a dyno and get real proof.

 

Yeah, go to a dyno and put this debate to rest. Real dyno numbers will end all debates as to its power adding capabilities.

 

I heard they dont blow enough cfm at full throttle high rpm, and even blow less then the engine is capable of sucking at high rpm.

I was thinking of grabbing one for my go-cart project though, sure it would be kick *** on a 20hp v-twin 4 stroke

 

hell, just put a boost gauge on the intake boost sensor line and see if it ever gets past 0 PSI

 

Well, Icemark makes us all look stupid again. That is the easiest way to do it.

 

Thats a good idea. It doesn't compress the air, so I doubt there would be any boost.

I agree with V8kilr, it more then likely doesn't move enough CFM to matter. These things remind me of those electronic blowoff valves for N/A cars. They make the sound as a real blow off valve so you can sound like a turbo.

 

some company did make one that was pretty impressive, I belive it had metal fins, dual sets of blades, and I remember a video of it levatating when it was turned on, and man was it loud.

on the other hand the ones on ebay are usally bilge blowers made to vent exhaust gasses of some sort on boats and such, they usally charge double what they cost from a place that sells them as what they really are.

 

i titled this thread carefully b/c i dont want to start a rash of kids running out to get these things...it was a waste of money but this thing seems to be pushing a decent amount of air and it is something different to do...ill try and see if i can get on a dyno soon. yes gtech's do suck but its better than nothing and ive had the same one since i got my car and i use it the same spot everytime to keep the variables of each run close.

 

yeah, you definitely titled the thread correctly.
It's all in your head. A little POS electric fan will not increase hp.

 

Has anyone ever dynoed one of these things? I'd like to see that happen so the results can be stickied for a week or to so this arguement can die like it should have a long time ago. I personally doubt they do anything, but I'd be happy to be proven wrong.

 

Route the air it sucks through a catch can filled with ice.

I contemplated NOT pressing the submit button but I couldn't resist...

 

Sorry, couldn't resist.

 

No they don't, they are a useful, inexpensive tool for comparitive testing. They will give you an accurate before-and-after comparison without the time and money associated with dynos or dragstrips. While I wouldn't use the figures as proof my car does a XX.X quarter, if you see a 0.5sec improvement on the G-Tech after a particular mod then that'll be very close to the improvement you'll see at the track.

 

I second that, now most gtech owners are rather idiotic when it comes to comparative testing, as they'll do one when it's 110 degrees out and their poor engine is screaming for mercy, and the next when it's 55 and at night, but if done under the same conditions it's a cheap and easy way to gauge performance improvements instead of driving 200+ miles to the nearest dyno (like i'd have to do)

 

Off the wall thought here buy could you use one of these blower fans (not the leaf blower) to suck air into your cold air box from someplace cooler than the engine bay? It might be easier to pipe the inlet because you can use smaller flex stuff.
Mind you, it's not the total volume of air you'll need but it just might be able to lower your intake air temps a few degrees.

Just run a duct like that from up near your bumper to the airbox and you wouldn't even need a fan, it'd getting it's air feed from up there.

 

heres the real one I was talking about,

AND NO I AM NOT SAYING IT WORKS, AND WOULD NEVER BUY ONE UNLESS IT WAS GOING ON A GO-CART

but heres the link

Watch the vid

Some Dyno Page

 

umm... u could probly make one of those things and save a buck or two!!

 

who would pay 300 for 4 hp.... and when its off you loose 4 hp.

i dunno man, i second the gokart thing. I think we need a thread about putting that thing on a go kart.

Comparitive testing, I guess it would work. But my opinion is based on my friends 12 second car had a gtech clocking it at 14.5. So with my experience of them, they suck.
