i read that a smog pump was used back in the day as a makeshift supercharger. the air hoses were just rerouted. would this actually work? if it does at all, how much power would you suppose it would help with?
a super chargeris basicly something tht pulls air through the filter, YOU MUST HAVE AN AIR FILTER ON A CAR.
the air goes in to the S/C ( or T/C ) and gets compressed in to higher pressure
the more pressure means the more air in a confined space
the compressed air going in to the engine through an hour glass figure, will decompress giveing you more air for more power!
a ram air system is basicly an uncontrolable super charger at like maybe 1 or 2 psi... the faster you go the more pressure comes in, the problem is getting it through the filter, a charger sucks it in with a vacume, no resistance, as opposed to a stock intake CAI or ram air trying to push in from the outside and pull from the inside
so THEORETICLY a pump thats air tight will work as long as you have a filter on it.
heck a leaf blower would techincly work...but 200+ mile an hour winds in to a 70MM TB is not a good idea! thats like EXTREME PSI

The transformation has begun!
does anyone have any idea if the air compressor for the thermactor smog system is strong enough to make any diff?
it may be strong enough jsut make sure your draw is post filter, and the exaust ( in to intake ) can be regulated to a certin PSI, put on a pre and post png you can use a digital gauge to check pressures after regulater maybe?
keep us posted!

Is the drag on the engine created by the air pump going to offset any power gains? The greater the demand on the pump, the higher the drag or resistance to turning the pump, don't you think? There's no free ride, so to speak.
This reminds me of those electric superchargers that are sold on Ebay. There's something that their ads don't tell you. The electric motor's drain on the electrical system places an increased load on the alternator. The greater the electrical load, the more effort it takes to turn the alternator's pulley.
well i dont know if it really creates much drag because the unit is very small and is belt driven. people have said that removing it rreally doesnt increase performance noticeably, but to a certain degree it relieves some stress. it probably weighs less than 8lbs. also, the other stuff that was part of the thermactor system would be useless (the exhuast collector pipes from exhaust manifold, etc.) so that takes out some other junk if that helps. i just want to know if anyone else knows how good of a compressor it really is because it may not even build enough psi to be useful.
i would do it except i am not much of a mechanical person. i just got into cars about a year ago and still learning alot. but i guess some experimenting wouldnt hurt. i just need some guidance on a few things. like where the hoses would go (intake manifold?) and how to gauge these psi and also how to seal it all up well. i have other questions but thats for starters
I seriously doubt the CFM output of the smog pump is anywhere close enough to make a difference on the typical automotive engine. But I bet it would work on a 5hp Briggs and Stratton go cart! A small 4v carb delivers about 600cfm through an opening of approx 5". The best I remember, the smog pump has a output hose of about 1". Even if the impeller is large enough to deliver,(I doubt) the ducting is not. Maybe if you are good, you could somehow mount three or four pumps on an elaborate pully system... Imagine trying to blow a pin wheel with one nostril, no mater how hard you blow,(psi) the nostril can not deliver enough air(cfm) to turn the wheel. Make sense? lol...
I would have thought that the smog pump would struggle to feed the machine, a leaf blower would be more fun

I know of two people that have done the leaf blower thing. One called it his "turbo" and was bragging about having one until the hood got popped open and people really saw what was in there. Home Depot plumbing piping and hose clamps, too .
