I have a Precsion Turbo 6266 dual ball bearing with anti surge housing and am currently running without a BOV.
I was just wondering who is running a BOV with their single turbo setup?
Do you think its needed with a single turbo??
If i was to fit one, where would the best place be? I have HKS intercooler pipe work so cant fit it in the standard place and have all the recirc stuff removed.
I have fitted a turbosmart raceport BOV in preparation for the fitment of a GT4094. I have placed mine on the pipe immediately AFTER the intercooler.
The subject of whether BOV's are NEEDED is one of contention and one you wont get a clear answer to. I get the reasoning behind having one and have changed my views on having one.
The idea is to put the BOV as near to the plenum as possible. This keeps escaping air in the system for longer and moving towards the plenum, but not entering.
Actually the best way to keep air moving around the system, but not entering, is to recirculate it. Adds a bit of messy piping though.
Run a greddy type 'R' set at 1.2bar with HKS to4z.
Funny that, was talking to a rx7 owner the other day about this subject who was insistent they're not needed if the single turbo has got a anti-surge housing...
I did read about the anti surge housing and what it did, it does not protect it from air getting rammed into the compressor when coming off boost, i think it does stop certain amounts of air from going back into it on part throttle though (if i remember rightly, could be wrong!).
Good to hear. I saw a video of a big power supra with a large BOV over the weekend giving it some and it did sounds insane when it dumped. Not normally a fan of BOVS but when youve got a big single and a nice exhaust they kind of finish it off i think.
