Hello EvoM I need your help and advice. I searched on the subject but couldn't really find any info (probably not looking in the right place)

Long story short: I am switching my car to speed density and I am wondering the best location to mount the bov. My old set up was a JMF intake with a Synapse DV recirculated. I purchased a JMF 4 inch intake w/no recirculate to replace old.

Since I am switching to SD there is no need to run a recirculated BOV correct?

Should I mount the BOV to the IC pipe? If so where is a good location or rule of thumb for placement?

Last question I promise, I can mount the IAT sensor on the IC piping as well correct? Placement?

Thanks a bunch in advance!

This were the BOV reticulates into right now.


Me showing the weld on adaptor, Is this a good place?


new intake


old verses new

 

BOV should be put near the throttle body, AIT should be near the intercooler on the lower section of the upper intercooler pipe, and you do not have to recirculate the BOV on speed density.

 

My iat sensor is just after the cold side of the intercooler, and my type s bov is just about where you're showing .

 

Thanks for the response boys!! I had no clue the IAT sensor went there, the only pics I have seen where guys tapping there intake manifold.

You have any pics around showing the IAT on the IC pipe?

Thanks again, Tim

 

Ill take one for ya I couldn't find one on google ... Go figure

 

Thanks Ratsbud, I searched Google too.

 

One of my friends just picked up an UICP with the AIT sensor installed.

 

Thanks for the pic.

My tuner suggested less than 6 inches from the throttle body. Hmmmm.

 

We talked a bit on FB last night, but one comment... I believe there is still an advantage to running the BOV recirculated.

 

I agree my self if it is set up properly.

It does help supply air to the compressor , and under racing conditions, the bov is completely sealed from environment .. Mine leaks at idle slightly and I am afraid stuff could find its way to the seat even with a steady stream of venting air

 

So I was told. Or in the Intake manifold itself. Just try not to cause too much turbulence.

 

Call The tuner And ask them. some tuners can tune on sd with out ait

 

 

Thanks Ratsbud, So now I am wonder if I should weld a piece on my 4" intake to make it recirculate?????

 

I don't see it hurting anything but empirical proof of it helping is tough to find
