N75 + RS6 Pop Off Upgrade, what do you think?

[Audi-Porsche Avant RS2]

Hello, what do you think about the N75 and RS6 Pop Off Upgrade on a S2 Coupe ABY and on a RS2? It's a real upgrade or only a commercial bright idea?

You can run the dump valve but not the N75, wouldn't like to see them results.

What did you find out from your pressure testing of the intake tract, that the N75 had failed?

[Audi-Porsche Avant RS2]

Hello, I have find out that I have two original S2 ABY MAF sensor broken, because the pressure test was perfect and so I have try to change for the second time the MAF of my S2 ABY with the MAF of my RS2 and now I have resolve the problem. Now I search for a new or used but good RS2 MAF.
I have already write it in my other post.
Thanks a lot for your informations!

Hello, why I can't change also the N75? I have seen the auction for the N75 race and RS6 pop off upgrade on eBay, but I don't know if is this really an upgrade or not.
Thanks a lot!

Because the N75 is specific to each car that's why they have different suffix endings on them.

There is no such thing as a N75 race valve, it's just a valve from a different car that has different reaction times and in most cases will cause weird boost control as the valve is not operating in the manor the ecu is expecting.

Thanks a lot! Now I have understand! I know that there are some differents type of N75 valve, now on my S2 ABY, I think that I have mounted the RS2 N75, but for know the correct type of N75 for every engine, like ABY and ADU, I must see the last letter of the Audi code or some other codes?
Thanks a lot!

Here is some info, part numbers and links to an article about testing n75 WGFVs:

My AAN came with an 034 906 283 H (that 034 also sells as "race"). I am currently running an RS2 ADU (also ABY S2) 034 906 283 K valve but I am not happy with it and will go back to the H.

Watch out for these subtle but important last letters on those WGFVs - they aren't just highlighting potential switching time differences - they sometimes have a different physical topology. For example the orientation of pipes on the 3B WGFV is different from ABY/ADU. Not always a show-stopper but worth preparing for as normal pipework may not accomodate a differnt WGFV.

Hello, now on my S2 ABY I have mounted the original (K) N75, so I think that is better if I don't change it?
