Re:Check valves = boost leak?
 

what the hell is this thing? how is the map supose to read any vacuum? am i missing someting?

Re:Check valves = boost leak?
 

how would it not read vacuum? you are missing something, or i am :P

Re:Check valves = boost leak?
 

It will read vacuum, but I'm suggesting using several in-line without using a "tee" at all.

We need a volunteer to try it.

This would seem to be an improvement over the widely used system of venting to atmosphere. It = less boost leak for sure.

Re:Check valves = boost leak?
 

wouldnt the check valve thats coming from the vacuum source close when boost hit?

Re:Check valves = boost leak?
 

It will work if the green arrows indicate allowed air flow.

It would work better if the "tee" was before the first check valve.

Re:Check valves = boost leak?
 

exactly, but air doesnt come from the map, its goes towards it. so when boost hit, the check valve would close. that just looks like trouble.

Re:Check valves = boost leak?
 

Don't you want it to close? Ya know...so the MAP doesn't read boost.

...and no boost leak.

dude no ----. i was thinking of some other ----. my bad. ya then it looks like it will work perfect. i was thinking about my setup. im using the afc plus one check valve so i can boost past 11psi with no cel. so i need some boost to get to the map but not all of it. OOOPS!i think im gona go to bed now. :'(

It's cool man... All these check valves and airflow directions can be a bit confusing.

I have to think twice about it also. hehe
