Thread: HowTo: Make a ReATM Turbo Valve

So i've never seen this before so maybe i invented this. So a lot of people debate over going "Blow off" vs. "Recirculated". For us MAF cars BOV means running rich when blowing off to the atmosphere. My solution is..... why not make some thing that will allow me to have both. When i want to be ricerish i can go BOV and when i want to some granny driving i can recirc it.

Here are instruction on making a ReATM Valve so that you can pop the hood and switch from BOV to recirc with out moving any hose


Tools:
Drill

Cost:
$3.99

Mat'l:
3/4" PVC Ball Valve ( make sure to pick one that open all the way properly


Note:
I'm running a HKS type2 SSQV with a custom 3/4" recirculating adapter that i made out of pvc. I'm also still running the HKS SSQV noisemaker tri-fins

Diagram



Original setup





Step 1: Close the Ball valve


Step 2: Mark spots to drill



Step 3: Drill two some <1/2" holes



Step 4: Deburr the shaving and open the valve to make sure it funcitons



Step 5: Install
Recirculated


Open to Atmosphere



Done!

Enjoy!! just remember you saw it here first


Same design can be used with any type of recirc'd blow off valve

i'm going to eventually epoxy a cone to amplify the sound

I tried to post it in the Howto section but i dunno what happend

Seems like a lot of trouble. If you just run blow through you wont have richness problems and you can still recirculate to be quiet.

what i was thinking but good write up tho

how did you fit the pvc into the bov?

Wow, do we have a ricer how to section? I just can't see wanting that.

How many people out there have done this and has it been something you continue to use?

Brent

This has to be the most amazing thing I have ever seen. Simply horrible.

stay tuned for the "how to: install a turbo boost bypass valve."

install a pvc valve before the intake and when you want to be NA just open the valve. but when you want turbo boost omgz, you close the valve!!

seriously though.. have we really come to this?

you WANT to be ricerish? and you think driving with recirculated bov is for granny driving? come on man.

lol, what a waste of good pvc.

stratton.

lol, I obviously like running BOV, but the ssqv is loud and sometimes at night i dont want the attention.


for those wondernig about the recirc fitting for the ssqv, it's just something i machined on the lathe out of pvc
