we have talked about the non turbo engines and some people using the air pump to force feed air to it but they way it was done before was thru the air intake snurkle and someone i cant remeber who said the idea of it was to force air to the engine after the injectors so here is what i kept thinking about last night

what if we were to remove the 5th and 6th port actuators and sleeves and some how force feed air thru there would it work????


iknow im an idiot when it comes to thinking but hey i gave it a shout please dont bash on me for this idea .

and please post saying yes its a good or bad idea and why it would or would not work...

 

The air pump doesn't have enough volume

 

maybe something else????? if you where to make the openings biggerfor the air pump might work allowing more air yo pass thru

 

The limiting factor is not the inlet and outlet sizing on the airpump, its that the airpump is essentially just a fan, and even if you opened it up completely the fan just doesn't have the capacity to blow any more air.

Hate to say it, but what you've described here is a just a very weak supercharger.

 

my point was about the opening for the 5th and 6th port
been used for something like this. i bet you that there is alwas something you can mod to vent enoght air in there but can the 5th and 6th opening beused for it or will it have some consecuenses?

 

If you got a pump that could put out sufficient volume and pressure to provide boost through the 5,6th ports openings (it sounds like you wanted to remove the shafts and feed boost through the openings), the problem would be that you would then push the mixture coming in through the primaries back up into the intake runners.

This would lead to a very lean situation, causing your motor not to run or to fail in a rather dramatic way.

Now if you had a 86-88 and you wanted the Airpump to activate the 5,6th ports like the 89-92 does, that can be done.

But to use the pump to boost the intake and therfore the HP, is not gonna work.

 

The problem with airpumps, electric leaf blowers, whatever people want to use, is all they do is blow air. A turbocharger or supercharger compresses a TON of air into a small area. There is no compression in a fan, or airpump or whatever, the amount of air being injected is minute compared to forced induction such as supercharing/turbo charging.

 

about it pushing the air and gas mixture back up causing the car to run lean.



and to the other person about airpumps not blowing enought go check the cadilac ones some push about 6#s

 

Pick up a physics book please. 6psi of pressure can be obtained by a person blowing up a balloon. Obviously, that would not provide a sufficient volume of air to make a difference on a motor though, would it? Its not just the amount of pressure, but the flow rate (volume/time) of the air at that pressure. How many cubic feet per minute (CFM) can that Caddy air pump push at 6psi?

Just to give you an idea, a rotary engine has roughly an 80 cubic inch displacement. At 7000rpm the motor is pumping 560,000 cubic inches of air per minute, or converting to cubic feet per minute that is roughly 325cfm. I'm sorry, but there is no way that a Caddy airpump is going to push 325cfm at 6psi.

 

I've got a better idea...

...reroute the cold air from the air conditioner to the air intake. Sure, overall you would lose more power than you could ever think of gaining since the A/C compressor is on, but the idea is soooo neat! Best CAI ever it will be!

 

What if you made a small box around the CAI, and fed the cold air through that? That would make the walls of the CAI cold, and maybe drop a degree or two

 

Even if you did have a lot of compressed air, you do NOT want to inject it anywhere after the AFM. You really need all the air going into your engine to be metered, or it has no idea how much fuel to inject. It would basically be a very big intake leak.
