Joern,
You just can not control yourself ! ! ! This is stronger than you ! ! !
You got a Sport Quattro and you are going to get more horsepowers out of
it instead of keeping it stock ! !
Regards,
Frederic

Hello Ned,
A truly good explanation, and I am a bit puzzled by the figures given in
inches and not mm. Is KKK a US company from the start ?
What about telling the whole story and include the turbine sizing logic
if there are any?
I have a K27 3770 MXA 9.12 turbo from a S1 and plan on installing this
on my Sport Quattro together with a Motec system. Is the 9.12 refering
to a turbine housing number 9 and what is the " 12 " ?
Or is this information secret with the tuners ?
Best regards Joern, MTM RS
