One for the maths gurus

Well you learn something everyday.

I think the Tdi only has around 70 killer wasps aswell.

So my older 4bb1 motor has more kilowatts than the later 4bd1 motor and the same bore but a slightly shorter stroke of 110mm. So would rev ever so slightly quicker. The 4bd1 is basically the same motor with a bit longer stroke.
