So lets discuss DV location. The DV is responsible for releasing compressed air after the throttle plate is closed in order to prevent compressor stall, surge, or deceleration.
I was sitting here bored this afternoon and started thinking about the location of the DV on the 2.0TFSI platform. Is it not in the least efficient place possible?
My thought is that the compressor has compressed all the air from the compressor up to the intake manifold, so having teh DV on the turbo causes all the compressed air that is between the throttle plate and the turbo to turn around and go back the way it came to be diverted back to the cold side of the intake system.
Just seems inefficient to me but mabey im wrong. What are your thoughts.

that that isnt the way pressure works.

the diverter valve is actually in a very efficient and effective location... its just hard to maintain and tune if ur a heavily modded guy... the "intake side" of our KO3's are made connected to the exhaust manifold and the diverter valve is connected to the exhaust side of the turbo... instead of having to release pressure that would have to go way back up to the intake pipe preceding the turbo or connected to the intake manifold preceding the intercooler, the whole system goes one way until you release pressure (ie let go of gas)... this setup is different from many FI system as far as i know and it is efficient b/c u minimize the lag-inducing piping that the released pressure would normally have to run thru if the DV was set up traditionally.

The way vw places the DVs within a couple of inches of the turbocharger, its mos def not the most efficient placement.

so speaking of this... would it be smart to get a revo chip AND a forge dv installed at the same time? i mean, can the stock DV handle the REVO? caus all i have seen on vortex is picture after picture of blow plastic diverter valves...

the stock dv sucks.. i would def. replace it before you get chipped (at least at the same time)

Its something that will fail eventually, but most people don't worry about replacing it until after its actually failed. Preventative maintenance is great, but if you don't have to spend the extra money right away...
Give me a call if you're ready for a Revo trial or full flash :upyeah:
