i have a 2000 a4 with the 8lbs diverter valve what would be the advantages to putting an upgraded 14lbs diverter valve from audi into my car.......yes this is a serious question

 

i think it takes a little more then just to upgrade the dv to go from 8lbs to 14lbs if your talking boost

 

no i mean the spring inside the DV goes from 8 to 14 i just want to know what the advantages are to the 14 lbs spring

 

are you able to run 14lbs from the turbo?

 

don't know its a stock turbo
im running around 7 now

 

if your not able to run 14lbs of boost and your not "chipped" then it will not be you any good to change the spring to 14lbs because you will not have enough pressure to open it

 

ill have to find out whatt the stock turbo can handle then first so the spring rate in the DV will have more boost correct

 

the stock tubo can handle 20 psi of boost but you need a chip to get 20 psi out of it if you just get a manual boost controller and turn it up you will go into limp mode and could damage the motor i run 18 psi of boost from a stock turbo and since i am chipped i have no problems.

The DV should be matched to the boost of the car. If you put to high of a spring rate in the DV, it will not open all the way, & much slower. This will cause some boost lag, & slow spooling of the turbo.
