[s-cars] Exducer diameter on rs2 turbo

[Tim Sexton]

Hello all,
    I was wondering if anyone knows the exact exducer diameter on a 
stock RS2 turbo? I'm wondering how it compares to the Porsche 951 K26/6 
exducer diameter.  I have a couple of 951 and Audi k26's as well as a 
pretty slick Powerhaus k27/26 hybrid that I'm comparing for the eventual 
turbo on my S4.  My poor old k24 is whining like an air raid siren 
now... thanks to some really severe boost spikes cause by a failing TAP 
bypass valve. 
    BTW,  it's hard to believe, but the the air pressure from the 
compressor stall caused by above mentioned failed BPV almost completely 
folded over two of my compressor blades on my k24.  It may be worth the 
reminder to keep an eye on the ol'bypass valves.  Especially for any of 
you other guys who, like me, may be running another k24 high altitude 
high boost car.
Thanks for any info on the RS2 turbo you guys may have,
