Here's Mafia....
I love these threads.
You love the noise - and put the BOV on the car to be a wanker. Its scientifically proven that if you're a wanker, the first thing you do when you buy a Skyline is install a vent to atmosphere blow off valve, to advertise the fact that you are indeed, a wanker.
Do you even know how the Nissan air intake system works? There is an AFM that measures the air entering the engine. The Stock BOV recirculates FOR A REASON. When your duck whistle, twisty whooshy twirly, dick pulling, sparkly, spinny, shiny, noisy, fuleh sic, wank off valve opens, it dumps air that the engine has measured and allocated fuel for. When only half the air gets into the cylinder because the air it measured is at the street corner where you sped up erratically and backed off because you saw some women on the corner, thinking that when they heard your BOV they'd get naked and run and dive into your car, the engine is now overfueled and under oxygenated, and stalls, backfires, and carries on. You know why? Because you've created a MASSIVE AIRLEAK on a system that will not run with airleaks.
Do you like that fact that you will foul your plugs constantly?
Do you also like attracting the cops attention?
Do you like the risk of being defected and having to pay money for a BOV that didn't need to be there?
Do you like the fact that you are just making skylines more hated? (And don't worry, its almost a guarantee that you'll drive through the main street of town making it release "because you like the wank off sound")
Do you like it how women love the sound, get naked and dive into your car as you drive past?
Do you think SAU will be happy about another "My car is running rough, I only installed a duck whistle, twisty whooshy twirly, dick pulling, sparkly fuleh sic wank off valve" thread
They should create a database script that bans people that install BOVs "just for the sound" or complain when their car runs rough...
I'm was running 300rwkw and had the stock BOV.
Good luck with it though.
