DIY: VF BOV to TIAL *Woosh*

Spun Crankhub · 10-10-2018, 02:09 AM

Want my VF620 to sound like a Chiron, so went about acquiring a Tial BOV. This write up will also work for ESS kits.
Tools needed: 4 and 5mm allen wrenches, screwdriver or socket for hose clamp attaching hose to intake pipe.
Parts needed:
*Tial BOV with GREEN spring. If you bought your bov without knowing which spring is installed you have to open yours to check and find out. It is held together with a series of allen style bolts. *Make sure to hold the valve body down as you release the final bolt, as the valve is under pressure.
*Greddy to Tial bov flange adapter
*1.5" pvc pipe hose cap from hardware store

This is a 2/10 difficulty level, and can be completed in under 15 minutes.
My Vacuum hose was only long enough to mount the BOV in this particular orientation, but not sure if there is any particular position that is preferable.

Does this BOV modification require any tuning to avoid running rich?

No. Our cars use a MAP to calculate air/fuel. If it used a MAF, then yes.

Absolutely no effect on.

Cold start, building on revs. I am happy that the bov is not super pronounced unless you are venting off boost from a higher rev. Unlike the setup on my 335i with the HKS SSQV, which was one single psssshhh, there is a little hiss for a few seconds after letting off on this setup.
