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

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.

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

stretch-d

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

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

RENR

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.

stretch-d

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

...and no boost leak.

RENR

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
