Can a variable orifice valve be used inline before the factory controller to set peakboost on the audi TT? I like howwith this form of boost control, asopposed to a pneumatic system,factory boost control logic is retained, butI don't know if it works with our motronic managment. That system is a lot smarter than me So has anyone used a variable flow valve or does something like the boost machine work best with our setup? Thanks!

 

ok I guess the issue comes down does the TT have closed loop boost control? The valve system only works with open loop boost control so does anyone know what the TT has?

 

Ehh, English por favor.... I think pictures would help here ha!I can't answer your question, but I do know that I am picking up and installing my TurboSmart dual stage controller in a few hours!

 

all you need to know is a ball and spring by itself is to fast for the TT. If you either use a bleed or combonation bleed and B&S, you will have smooth boost control and then can dump the stock n75 (boost controller). Best mbc for the job is the turboxs hpbc

 

Thanks for the tip. You helped me out with a good deal! Looked on ebay and there was one for twenty bucks with 10 minutes remaining.
