Dump Valve Is It Needed?

[Thorpy]

just wondering is a dump valve needed?

i have an external wastegate now so my garage that fitted it removed my dump valve because he said its not needed now with the external wastegate is this true?

or would i benifit from having both?

I would avoid this garage in future.

The wastegate is on the exhaust side, the blow off valve is on the intake side, they have nothing to do with eachother.

A lot of people run without a BOV, but I wouldn't. Some say it will be fine, some say otherwise.

Sounds cool without one though!

yeh does sound better but id rather be safe than bugger my turbo up so is it deffo a must then?

[ste91]

You wont bugger your turbo up just like that. But I'd put the BOV back on anyway.

The bloke at this garage doesn't have a clue.

im having this chat on another forum at the mo but we are on about it being done on a 200sx s14. The mod is called the pigeon mod so i can tell and is very common on the 200's.

once i know more i could pass the info on if wanted but i wouldnt person try it untill i know a hell of a lot more lol

[Thorpy]

i think i should put it back on then i was gona sell it if not because its sat doing nothing

any more info would be good need as many opinions as poss so i know im doing the right thing:)

You can run both a BOV and EWG together, the garage is talking poop

IMO it'll be fine without the bov, afternall, a bit of boosted air ain't gonna bend metal.. Ok it may wear seals a bit quicker, but so does fitting a decat & people still fit em !
