Sure, in theory. Unless the stock BPV has been shown to leak or fail, then it's really a waste of money. Bumping up the boost on the stock turbo is most likely still going to be within the engineered safety factor.Yes, if you are running additional boost thru the installation of a piggyback tuner or aftermarket tune. It will provide quicker boost recovery during shifts, more consistency and reliability operation. It will also keep you from damaging the diaphragm of the stock boost control valve. This generally happens when the boost is higher than the OEM BOV specifications and the BOV can handle.
Ah yea, you asked and were informed.Is there any reason besides sound, to change the factory bpv?
LMAO! No, in reality actually!Sure, in theory. Unless the stock BPV has been shown to leak or fail, then it's really a waste of money. Bumping up the boost on the stock turbo is most likely still going to be within the engineered safety factor.
Uhhhhhh, yeah, it was more of a rhetorical question regarding the sound. I know about BPV/BOV's. This is not my first turbo car.Ah yea, you asked and were informed.
LMAO! No, in reality actually!
An OEM boost valve doesn't recover nearly as quickly as and aftermarket valve between shifts to maintain active boost on acceleration. Anyone who has use them, is aware and knows it! It can either be vented to the atmosphere or the recycled, doesn't matter but will be far more consistent and reliable, then the OEM unit. Add a boost valve module and it's even more robust and accurate. The OEM valves are crap quality, straight up. Any static increase of over 20 psi on a continual basis, across the rpm range will deform and tear and OEM's diaphragm.
Bumping boost, moot point it's already been done with many of the piggyback tuners already available for the N.:grin:
Yes, it will improve performance but not as a power added. It will make boost recovery between shifts much faster, reliable and efficient. It's fairly noticeable on dynamometer and the seat of the pants, on the road.Will this product improve performance?Max
Sounds like they sent the wrong one. They sent me a VW atmospheric adapter by accident when i ordered mine lol gen racer takes mistakes very seriously and he was relentlessly messaging gfb to correct the issue for me.All I know is, i installed a recommended T9110 part number, GFB Mach 2 recirculating valve for my VN,
this is the one genracer dot com sells for the i30n + veloster N, the mounting o-ring doesn't match the factory o-ring, and ever since i installed it, my car sounds like a vacuum cleaner. I've read as much as I could find on the valve spring for BPV's and have tweaked this thing tight and loose. Returning it :/
the bov from this original post does have a mounting o-ring that matches the factory o-ring... but i dont know - im going to put the stock one back on and see if my car sounds normal again lol
