Otto,
A late friend of mine, Bill Edwards, had a picture above his work bench of
a turbo Offy at full chat on the dyno. The exhaust pipe going into the
turbo
is lite yellow with white patches. The pipe coming out is a very dark red.
He kept above his bench (at work) to show where the energy came from to
produce boost.
