Hello everyone, I own a 2002 Audi A4 1.8T Quattro, and I bought the Forge 007 Diverter Valve and I have heard about installing it in reverse. I have been researching it for days now and still haven't found the benefits if it. I also have other questions..

a) Does it make it louder?
b) Does it make you faster?
c) Is it bad for the turbo/engine?
d) Do I need to use a spacer that came with the diverter valve? I am guessing it pushes about 8 PSI stock.
e) Also, will I benefit from changing the springs to a stiffer one?
f) If I install a cold air intake, would I need a breather filter? This is the smaller filter for the AUX air pump hose that is attached to the factory air box.
g) Is there anything I can do to make the stock exhaust louder?

Basically I want to know why it would benefit to install in reverse. Any help is GREATLY APPRECIATED!!

Thanks,
Giuliano.

 

I would say install it the way it was engineered, reverse installation could either bleed pressure when not wanted or worse, not dump boost when throttle plate closes.

 

Thanks for the advice!
