is this a redneck way to get SOME boost?

[red89yj]

my car was on the lift today getting an oil change and while i was looking around i noticed that where 2 cats were replaced with straight pipe, i have this skinny little tube (probably from the air pump for the exhaust) still wide open. the light bulb went off and im looking for some feedback before I waste time doing it-

if I routed more tubing in there from the original tube up to my intake, will the air pump crank out enough volume to make a difference in HP?

If I did it, would there be crap flowing into the intake that shouldnt be?

Should i just clamp the tube and forget about it?

sorry if this is a worthless thread but i just have to ask-

I would abandon this idea. It has been discussed before and concluded to not pump anywhere near enough air for a significant improvement in air flow. I would not force any air into the intake that has not gone through the air filter or at least the mass air meter.

 

[red89yj]

excellent call- just the reasoning i was looking for

I completely agree. One more thing to remember - you have manifold vacuum pulling air into the plenum. So anything you do has to be above and beyond the 'ambient' air flow magnitude. A smog pump puts out ok air flow in stagnant air but otherwise is going to be pretty useless.

ok i read this wrong apparently i thought you wanted to run a hose from your h pipe to your intake

no where enough flow.....a turbo or a supercharger really pushes ALOT of air.

People have used those smog pumps on briggs+strattons to make supercharged gokarts!

i have seen leafblowers hooked up to our cars try that haha

i saw that on powerblock tv a year or so ago. haha

SO, now that we all know this is a dumb idea and won't work for Sh!+, should i clamp it shut or just leave it alone?

clamp it. I like that sig, by the way, that 03 Bumper would look incredible on your car

 

[igotyofire]

heh need a compressor of some sort

Actually, don't clamp it. It'll be fine just pumping air out into the atmosphere, but if you clamp it off it'll still be trying to pump air. but getting nowhere. (Robbing horsepower)

I've wondered about this.

If you could put a decent sized tank in the rear and a compressor like the ones used for air lockers I think it could be done.

Kinda like a NOS system but with compressed forced air like a turbo or supercharger provides.

 

[trav_19]

hmmm you would need to use in-line dryers to keep any water out of it....and what would you use like a bagged system for this?? the ones i see dont fill extremely fast so you wouldn't get a huge rush of air for very long ....

 

[Voice of Reason]

When I had my air pump off earlier this year I think I remember seeing a sticker on it that said 28lbs/hr. I got to thinking and if it would take an hour to pump a tire up to 28lbs then it ain't exactly pushing enough air to be used as a redneck supercharger.

remove it as i did and make a few bucks off it...i sold my pump & lines on e-bay for about $20 plus shipping....heres a link on removal http://www.allfordmustangs.com//techarticles/Smog2.pdf

I was about to say... dont clamp it...

 

[trav_19]

wait...what are we not clamping??? the small pipe on the h pipe?!?

 

[The Green GT]

I dont know if anyone said this, but the smog pump shoots out air in bursts. I dont think a MAF would react to well to that. lol

Actually, one would gain horsepower.

i.e. when you block the intake or output duct to a fan, the amount of current the fan consumes goes to almost zero. If it doesn't move air from A to B, there is very little resistance, thus no power draw.
