VW airflow (!)

They probably draw 950 l/sec of *cooling* air, and I'm no mech.eng.,
but 6000 rpm = 100  revs/second. Therefore 950/100 = 9.5l/rotation.
9.5l/1.7l (*100%) = 550% V.E.

Assuming the average V.E. for a worked normally aspirated engine
is 75% (guesstimate), you might shove in that much air with a turbo
pushing around 100 psi., and making about 700+ hp.

I think there's a typo in the manual. 95.0 l/sec would be beleivable.
