DV Help

I have been looking into Bailey's DV's but can't seem to find a US website that sells them anyone know any?? And how much boost do forge dv's hold? how much do bailey's hold? how muchh do hyperboost hold? i know it is better to have a dv that can hold more boost than your car produces but by how much? if a dv can hold say 20 or 30 and your car only produces 10 or 15 will it make a difference? will the dv that holds 60 out perform the 20 even if your car doesn't produce 15 or less? if you get what i mean any help would be appreciated. Peace

are you gonna get a bigger turbo in the future?

if not, then just get any, they are all good, holding more than you'll ever use

A bigger turbo is on the list but only after gauges, turbo timer, DV, exhaust, new chip, maybe new springs and shocks... we shall see

just get any

Forge is the most recommended simply because it's the most used, meaning there's no problem with it and everyone loves it

thanks for the feed back man

welcome

any dv works if you dont chip it or upgrade the turbo. if you dont plan on doing any of the two, stick with your stock valve. no need to waste money on something you dont need.

if you do get chipped or big turboed, then buy any aftermarket dv with a piston. the stock one works using a rubber diaphragm which is known to tear at high boost (above 17psi or so). almost all aftermarket DVs use a metal piston now, so it doesn't matter which one you buy. if you plan on getting more upgrades that change your boost, get an adjustable DV.

and for reference, stock gti/golf 1.8t boost levels are 8-9 psi for model year 99.5-2002 and 10-12 psi for model year 2002.5-present

i know about 10 people personally who have had their stock DV's go bad on stock low mileage cars, on all three 1.8T engine types...just do yourself a favor and pick one up, they're not that expensive, and you wont need another one if you upgradge your car.

m... 10 people.. maybe it was just a bad batch from bosch.. cuz i know a million people (ok... or not, but alot more than 10) that have perfectly functioning DVs (stock ones are only $30 at the dealer). o well im just an engineer minded dude i guess (if its not broke, dont fix it).
