fitting dumpvalve

[podge07]

fitting a dumpvalve on a ps13 sr20det engne do i fit it on the throttle body side pipe or the turbo side pipe
thanks podge

Basically, you can fit it anywhere between the turbo & throttle body.
The idea for a bov is to stop compressor stall & reduce lag between gears (nothing to do with vroom-tishhh, right ). It'll be most efective if fitted nearer the throttle body, but if you just want the noise it doesn't really matter

Depends on the DV. Some leak on idle causing the engine to hunt and in my experience they can cause over fuelling when changing gear. I used to have one on mine years ago but binned it because you could feel the car bogging down as you floor it after a gear change. I could get rediculous flamage though.

[islander]

same here on mine.

steve would you say that the more expensive dv the better it would be.
I know mine is like £300 odd quid but you can get some for like £30 from ebay,
is there any difference?

i fitted a bailey on mine, and my mate bought a "jdm" one from ebay for 30 quid and i didnt come with a fitting kit, so its totally useless, i supose you get what you pay for, as with many things

[Maximus Driftus]

I bought one greddy look-a-like for my RX7 - was leaking like hell, even closed completely was hissing like a mad snake, car was over fueling and hunting - mad house! so I changed it for a real mccoy - worked the treat! as you said - you get what you pay for....

[SteveC200]

I wouldnt run one at all, IMO they are totally useless apart from making gay noises.

just out of interest then, what do you have then, nothing? and is it true about the pidgeon mods damaging the turbo?

[SteveC200]

Yep, nothing. No problems so far running 1.6bar on a GT2871R.

well i was thinking of removing mine, a bailey dump valve, but if i do what do i do with the small hose that comes from the top of the valve to the inlet? just blank it off? also i am running a boost gauge from this pipe, so will this affect the gauge or can it stay where it is

[MJG]

Not many drifters run any kind of DV as they are just gay chav mods "I gots me a turbo init mate".

You blank off the small vacuum pipe yeah, or run it straight to your boost gauge.

thanks mate. and good show last night, love the noise of your e30, its imense! some excellent drifting, a really good night.

[MJG]
