Hey guys, Been offered a bov for rather cheap, so was just wondering if anyone actually knew the weather or not u could put a bov on a vl turbo without changing the computer. Im a mechanic myself, but no other mechanic will give me a straight up answer and ive never played with turbo's before. If anyone has done, or seen this done before let us know. Cheers heaps |

From what I know, you can as long as it's a plumback setup, at work a 300zx was running like a pig, and it turned out that an open air BOV was the cause. Something to do with when they backed off the air wasn't flowed back through to keep the turbine spinning, something like that. But I didn't actually solve this issue, the boss did, I just remeber talking about it. |

Your on the Coast yeah, ring Matt Aspry at PITS, Performance Injection Tuning Services, He'll give you a straight answer, the lads a wizz with Nissan motors. the reason the open air BOV would cause the car to run rich is because it stuffs up the reading from AFM.... the air comes in going past the AFM, but then gets vented out, hence more fuel has been given according to the AFM reading....then rich, there u go.... apart from that, i can not really see anything really big... |

It wont kill the turbo in the sort term Nvious, but long term will cause play alot sooner. |

as already stated, the air releasing out the atmo bov has already passed your afm (air flow meter) as you ecu thinks there is more air, it adjusts the fuel accordingly, causeing you to run rich at times, some cars tend to splutter and fart a little, mine backfires or blows a flame. no biggie. |

Bov venting to the atmosphere are really only suitable to MAP sensor equiped cars not AFM ecu's. Psst VL turbo's never had a Blow-Off /Bypass Valve from the factory. They're not needed and are really only used as an emissions control device or to make the turbo STFU and not make turkey noises on decel. |
