Hello all,
I have been toying with the idea of using a homemade 3" pvc venturi to force air into the 3.5. The unit would be just big enough to fit between the MAF sensor and the throttle body. Seeing as i need compressed air to generate a vacuum effect in the venturi i thought about possibly using the waste exhaust pressure. I know what your thinking, "Exhaust is hot, cold= power. My venturi uses the hot exhaust only to provide vacuum, it does not actually force the hot air into the usable pressure.
The more gas you give the engine the more compression it provides which in turn would push more pressure out of the exhaust. I would use a 1 inch line tapped about midway into the exhaust underneath. The problem is that i need a way of capturing enough pressure without putting to much back pressure on the engine.
I could also use a cheap air compressor to generate pressure but they are loud and its not practical to have a generator running all the time while you drive...especially in a hot engine bay. Does anyone have any input on this idea or reasons why it would not work?
I would really appreciate it. Thanks
The diagram is a rough idea. It demonstrates a simple venturi for those who dont know what it is. The real system would not force the air into the TB.
