smog pump super charger?

metallica21156 · 05-24-2005, 09:52 PM

i read on one site that you could hook up a smog pump as a super charger. i know that they have decent psi and cfm but the site said that you would need 4-6 of them for decent performance from a V8. i thought of using 2. i have the 4.3 CPI. would this work? i would put more on but space is very limited to this motor. would this work or what other things might i be able to pick up at a junk yard cheap that will work?

Sounds like a good idea, except for the part about 4-6 of them??? Where are you gonna' put 4-6 smog pumps?
Did the site mean 4-6 lbs of boost?
Even 2 smog pumps is gonna take a little hocus-pocus. Now if you could put a bigger pulley on the pump itself, and then split the airflow, with some air going to the intake, then you might be onto somethin'...

smog pumps put out air flow, with little pressure.

True, LT, but how 'little'?

So with a LARGER pulley, as opposed to undersized pulleys which supposedly give more HP, how much more CFM's would a bigger wheel give. I think there's something there...

CFM is airflow, PSI is air pressure.

This pump is not made for high pressure or high flow.

Just drop it, it will not work.

i think he does have a good point. if i were to run 2 of them and run them faster with a smaller pulley then i should be able to get at least 3 PSI from it. even that small amout is better then nothing at all and it will give you some boost in power with out over doing it or shortning the life of the motor. the guy also clamed that for a very short period of time he could get 60 psi out of it. he also clamed that with a 5 hp electric motor hooked up that if you put a cap ont the exhaust side of the pump that it would stop the motor. i don't know about stoping it but it would have slowed it down. heres the web site.

Why on Gods Green Earth would you want to do some thing like that. First the amount of horsepower needed to run 2 or more pumps would wipe out any boost. 2nd with GM known for crap gaskets why would you want to add any boost to a engine that is NOT set up for it.

EXACTLY!

You can't say it won't work unless you've tried.

The only part that seems hard to figure is the part about 2 pumps. Seems to me there's no room for extra components, but with an oversize pulley, you're gonna get more air flow from the pump.

Fireplug · 05-25-2005, 10:51 PM

And just how do you control the boost?? How do you read the boost going into the engine?? I never said it would not work read my post

Gimmie a break, no offense, but why don't you do some research on low pressure smog pumps before you question what we say.

If this was that easy, don't you think everyone would be doing it?

Can't blame you for wanting to try it. But I agree with the guys . It does not have the volume . You would have better luck adding a leafblower to it with a power inverter. I did a water injection on a FI engine 20 years ago that gave it more power than the smog pump could . Rob

metallica21156 · 05-26-2005, 08:44 AM

now how is water injection going to give you more power? i thought water killed the motor. i don't know to much about so fill me in. to measure boost any boost on the motor you would just pull the tube from the back of the intake and put a T on it to split it to the gauge.it has a vacume on it or boost. its part of the intake. or if you really want you can pull the intake and drill in a new plug.

You guys are making this way to complicated. If you want to get a boost:

Pull the line going to your windshield washers off and tie it pointing into the throttlebody.

Fill your washer resevoir with racing fuel.

When you want a boost just hit your washer button.
