PS2 Setup Diverter / BOV Help

Lyfe.In.A.M2 · 06-06-2023, 12:13 PM

Hey All, I recently swapped my stock turbo for a Pure Stage 2. I didn't have an upgrade for the diverter valve on hand so I went and reinstalled the stock valve onto the new housing. Everything is going well atm but I'm not sure what could be the long term effects of not upgrading this. I plan on running a full E85 setup in the future and don't want this upgrade to be a hinderance in the process.

I was looking into upgrading to a TurboSmart BOV but I'm unsure if there really is any benefit from upgrading or just leaving it with the stock diverter valve / BOV. I don't care about the *Whoosh* sound that I've seen turbosmart BOVs make I'm more concerned with the integrity of my turbo.

Thank you

Better throttle response and it holds boost better. I don’t really hear much from it though, I have the plumb back version.

I have turbosmart BOV version. It's actually a dual port, means it only vent 50% air out. Very sensitive and responsive during high load and it's not too loud. Works great.

There are 2 versions available from Turbosmart.
The plumb back recirculating version & the dual port version which partialy vents to the atmosphere.
Unless your a fan of the whoosh noise stay away from the dual port version.

Performance wise, there is no difference. All sound preference for two versions of turbo smart. This is it

Just want to say, if you get an aftermarket intake..The plumback version still gives a “woosh” sound..When i installed the crs intake it made the bov noise quite noticeable
