T4 Dumpvalve option?

Hi, First of all, thanx for all the inputs, I do enjoy the sporty bunch with sportwagons ;) I bought myself a 2002 V40 T4, and do like this car enormously!:Banane32: Just wanna know, can we use/fit dumpvalves? What is the power implication? This is part of the reason I got a turbo, the whole pffft sound making your wife mental when the foot becomes heavy:Banane59:

A dump valve will make no difference whatsoever in performance, might use a bit more fuel but probably not enough to notice. Make sure you set it up as light as you can to stop the back pressure destroying your turbo bearings.

thanx! One thing..... ....can one do it to a T4? How hard is it to install? DIY?

Pretty siple to fit, all you do is cut the top intercooler hose and put a 63mm t-peice in and fit the dump valve, you can t into the vacum hose right by top hose as well!!!!! One thing i will say is get another top hose as it's a bit tricky to cut it well enough to use one top hose, i had to use two top hoses mated together to get the clearence I needed to fit the t piece!!!

My Forge one was even easier and came with pics and instructions + Parts for Volvoe delivered in a matter of days after ordering...a must for any T4 owner - or T$ wannabe 2.0T driver...
