ok so what up with these "check valves"
what are they?
where do they go?
what do i need them for?

can i do sumthing different then use them?

a check valve is a valve that lets air pass one way but not the other. it has nothing to do with a turbo or none turbo car.

There are many different sizes and shapes of check valves. Basically they just restrict air flow one way, and allow it to freely pass the other.

They can be used in many different situations

i'm doin it on a 7afte

how does it play into the 7afte
setup and why

If you dont know how or why, why are you doing it?

i sent a pic to coomer of my check valves for my old 7afte he hasnt got them up yet


they bleed off pressure between your manifold and map sensor so the map doesn't see your boosting thats what they do

on a NA setup they're used between the crankcase vent -> intake VAC line so that the crankcase isn't pressurized.

Know you talkin bout turbo setups....but thats just something else they're used for.

>> i have forged jdm check valves that have been custom ported in japan >>

well you plug one end into the map sensor and the other in the Intake manifold replacing your old line that went from the manifold to the map >> or what did you want to know?

well thats all haha

unless you have an installed pic?
cause i've gone through your how to
and didn't really see/hear much about them

as i explained further up

"they bleed off pressure between your manifold and map sensor so the map doesn't see your boosting thats what they do" NIK

go look under your hood see the map sensor and the vac tubing coming out of the bottom and going to the intake manifold ..... now see the pic i posted you pull off your tubing and connect the check valve system and your done dude you should know n/a map sensors dont like boost so this is how you fool them or you can hardwire in a 1 or 2 bar map sensor but you have to make sure the ecu can under stand it go out a buy ..... i can remeber the of that boosting book anyways go read up it will probably answer some of your questions you keep asking

yea max boost....

thanks
