blow off valve

[Gradenko]

34GTt, I fully agree that most stock items are only useful upto a certain power level. In fact, the r33 gts25t airbox is useless even at factory power level. The bov doesn't fall into this catogery tho, you'd need to be running more boost than the stock turbo can push before the stock bov starts to leak. In any case, I'd rather not carry on about the pros and cons of bovs. As Strich9ine said, to each their own.

Just one point though,

if the stock item is so up to scratch why are there so many aftermarket products ?

You could probably use this argument to push those chrome window washers with blue lights. All much the same market segment, isn't it?

Whats wrong with chrome washers and blue lights? werent you happy with the set you got for your car? BTW hows those under car neons going?

j/k

Back to the point, if you want a laugh, check out some of the silvia forums, there's P platers who post there things like:

"Whats wrong, i paid $300 for a 'insert brand here' BOV, it sounds really nice, but how come my car backfires now?"

If a BOV causes a backfire, wouldnt it actually lose power during changes?

When i got my car it had a BOV on it, and it was really backfiring, i used it to bargain the price down, then i got it home, and plumbed it back. The only reason its still there is cause i changed the cooler, and it was easier to keep than the stock valve.

Suppose it may be a compromise, reduced turbo backpressure and less lag v's backfire.... I dunno, but wouldn't mind knowing for sure.:confused:

love your action with the aftermarket bov = sell me the car cheaper, nice work

Radium, ive got the same issue right now with mine. Stock BOV venting into the intake which has a HKS pod attached. Damn thing is loud! I kept looking for one that had been placed down near the intercooler (my brothers 180SX was like this, stupid place for a BOV). Anyway, turns out the stock one is still fitted and ill just have to live with it being noisy.

I just hope they dont have a go at me tomorrow when i try to register the bloody thing. Ill be back on here asking you lot for an R32 stock airbox!

ive still got my stock airbox if ya get stuck

[34GTt]

heyy wts wrong with p plater's ? haha

well i dont know why` but my car is backfiring less than it did before ...

anywayz i think i'll go for the Apexi bov, or since i cant sell my hks one i might just keep it

[red17]

Turns out i didnt need it. The engineer has approved the intake and the pits cant refuse me registration for a stock standard part thats working correctly (BOV).

So they had no choice but to rubber stamp it and gimme some plates.

Now all i have to do is chop the ends off em to fit proper like
