[s-cars] Attempted Translations from Garrett to KKK Speak

[Mihnea Cotet]

IMHO James' compressor wheel is a 27 compressor wheel, according to his 
measurements, I'd say it is a 2769 compressor wheel, maybe 2770.

If the "big" diameter of his compressor wheel is almost 2.7 inches (2.694 
can be rounded off to 2.7, just as 2.598 can be rounded off to 2.6), then 
the compressor wheel is a 27, not a 26. This is about the basic KKK 
numbering system so I'm pretty sure James' wheel isn't a 2672 compressor 
wheel. FWIW, James, can you please post some pics of it and give us some 
measurements like the exducer bore for instance? Is there a KKK type plate 
on the turbo with an "Ausführ.-Nr." on it?

HTH and thanks,

Mihnea
