Blow Off Valve's

[bustafat]

Here's the story

I want to get a blow off valve for my car (Stock r33gtsts1) and have seen a

few good ones on the forum,

but a friend of mine recently told me not get one

unless its plump back

she got a r33 s1 gtst as well, and when she had her bov

she had to keep her car revved up otherwise it would stall

i thought it was possibly to big, but she said it was just a standard

turbosmart bov

so here's the question, does it have to be plump back?

cheers

doesnt' have to be plumback although if ur only after cosmetics like sound etc etc then yeah atmospheric bovs sound better for performance wise i'd suggest stickin with a stock one

i have an aftermarket hks ssqv in ma gtt sounds sweet as and i think they are startin to make kits for the ssqv's now to make them plumback

It doesnt have to be plumb back but being plumb back will prevent possible stalling issues?

If you have a AFM orientated car, then you need a plumb back full stop.

Do I even need to explain it? AFM Measures the air, and then your stupid Vent to atmosphere BOV wastes that measured air when it is not supposed to.

Engine thinks air is going in, so it adds fue. Fuel gets there, and the only half the air does. (cause the other half went out the BOV) and the car stalls.

Put the factory one on and stop trying to be a show off.

get a gfb hybrid or stealth etc part plumback part atmo, i have a hybrid, that works great, although now its not part plumback due to no afm anymore...

Can't say i totally agree, as in i have a atmospheric bov along with a lot of people on this forum and my car does not stall. a lot of the turbosmart atmo bov's like mine (stage 2) have an adjustable spring rate by turning the head of the bov, by doing this you can achive the correct spring compression which will keep the bov closed during idle and hence not stall. I agree that the afm has measured a certain amount of air which is then changed by the bov when it vents and hence the afr's are out of wak a times during shifts but you can still run one on your car without dramas. I have had my stage 2 for about 6 months works fine. Also have one on an s15 and no problems either.

does putting the afm in the cooler piping stop the stalling? thats wat they do on the vlts and it helps or something. cant remember the reasoning behind it but

[R34GTTSKY]
