seems like thats the opposite of what u want, dont u need the catch can to connect to the intake to SUCK the air out of the crankcase? wouldnt this create alot of force into the lines that run into the crankcase? wouldnt this create more pressure inside of the crankcase instead of relieving it?

the way the nipple is designed it will create a vacume from the exhaust flowing past it. i know it would work well with an open down pipe but on a set up with full free flowing exhaust i am not so sure it would create a vacume like it is suppose to.

That also looks like it uses air pump type one way check valves. So no exhaust could come back into the lines.

yes, those are once way check valves so no presure could get back into the crank case. would you run a valve cover breather too? i need to get on the supra site and find out how populur this set up is and how much exhaust then have after the down pipe.

moroso evac system

I used this on my NA engine. it works well
it eats the check valves every 6 months or so
it is a ford air pump check valve
theyre pretty cheap compared to a vacuum pump setup

and isn't velocity going through the opening and out the bottom creating vaccum so the higher the velocity of the gases the more vaccum it pulls am i assuming right

It works. You just want to make sure you have them after the wideband so the oil doesn't hit it.It pulls a nice vacuum under boost conditions and can give you some nice HP gains.

The downside is that oil will collect in the exhaust causing some nice smoke on daily drivers.

no catch can! no oil in the intake! my big question is will this work on a set up that has more exhaust than an open header or down pipe?

i might have to give it a try. that supra pic has a threaded fitting on the top of the check valve. i am worried about heat on that check valve and hose on the top of the check valve. i wonder if using an extention on that nipple to get the check valve farther away from the down pipe would cause any problems.

This will only work effectively if you have 0 backpressure in the exhaust. It is popular with the N/A Drag cars that used to be able to run open headers. With everybody running exhaust with mufflers, there is backpressure and it will not suck well. Measure your exhaust backpressure.

I wonder if it would work on the tailpipe after the muffler where there is no backpressure. (or it may lose too much energy travelling the length of the vehicle. )

I thought about trying it, but just ended up going with a crank driven pump.

hell yeah there ya go. the velocity coming out of my tail pipe is nuts. i will stick a vacume gauge on the crank case and see how much presure/vacume i end up with once i give this a try.

Can someone give me the quick and dirty reason on this type of setup (to pull pressure out of the crankcase but what effect does this have?) and how much hp gains are seen? Sorry for the noob ques...just need the knowledge.
