    Dyno testing.

    Tomorrow is the second round of testing on the dyno for that custom turbo inlet pipe.

    Also I will be testing a new N 75-K valve to see if it holds the boost longer than my stock one.

    I will most likely be able to post some dyno plots.

    I'm told that the N 75-K is only available through DBR. L-Sport in Montreal deals with DBR and that's the shop making me my custom inlet pipe. They are also the people with the dyno.

    I'm told that the K version of the N 75 was used in the Audi RS 2 in Europe.

    It is suposed to be the valve with the steadiest boost, no surges and will keep that boost longer.
    I don't know if it actually allows higher boost but we will find out tomorrow.

    I currently peek at 20 psi but redline at 10 psi. Let me know how much more boost you retain with -K once you get done testing it.

    Its kinda weird that the N75 valve hasnt changed in the 5+ years.. I would have thought Audi would have made a "newer" style one etc by now... My point being is that the Rs2 is an older Audi..

    Cant wait to see how it performs..

    Lots of interesting results to show you. But later only got to get ready for my little girl's soccer game after supper.

    im desperately hoping you come back saying the n75 works, and is safe...so i can use it with my APR stage 1, should be a great bang for the buck mod, but i've heard some not so good things about using them too
