hi all, i normally dont even look at posts reguardin dump valves, as im sick of all the peeps talking crap iv had one of stus dv on for years and never had any probs or damage the simple fact is if it dident have one fitted a standard its up to you weather u fit one or not..simple or if you have erst fit one of stus electronic box,s ..and dont fit anodised
i talked to the guys at castle about it and he said d/v were first thought of by ford, and said when collin mcrae was rallyin thay were devised so he cud change gear faster.. thus gettin rid of the back pressure and bein able to change gear faster so people should look into why thay were first invented!!! instead of slaging them off, if you dont like them take it off, or if it was made with it on you should leave it on and not vent to atmosphere whitch is what ford did
i have a switch on my erst and can turn it off or on , and i think it deff goes thru the gears better with it ON!!!
