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.

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

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.

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.
