standard bov

[GtstCoupe]

what happends if you disconnect the plumback hose from the standard bov ,will it make noise like an atmosphiric type of bov, or will this cause so problems.

thanks guys

i tried that once and yes it makes the atmospheric noise. not a good idea though, i believe the stock ecu compensates for the loss of air by over-fueling.

so does this happen with aftermaket one like hks greddy etc like over fueling

yep, that happens on any car with an air flow meter, you need to change the setting on your ecu to avoid it.

but i guess any plumback is ok and wont overfuel

i know GTR BOV's are open @ idle, stock 33-t i cant remember

aftermarket ones might not be open a idle which causes some issue. cant remember.

stalling i think

It's not exactly putting extra fuel in .. what happen is the air flow meter measures how much air is getting sucked into the engine and the computer puts the right amount of fuel in.

When you don't plum it back you're sending air the air fuel meter has already measured (and the computer has calculated on being in the engine) into the air... So this means that the car is left with all too much petrol everytime you hear the PSSShHHhHT.

Thats why leaving the stock bov is the way to go

I've learnt after many stalls with my SSQV.
