RE: Theoretical HP



At least to the mid 70s, Illinois and Chicago used taxable horsepower for
tags. It was calculated on bore, number of cylinders and total displacement,
in Chicago and I believe Illinois there were under 58 hp and over 58 hp.
I remember that the break point was somewhere in the 300 cu. in. area.
If memeory serves me correctly there was a case where two 3XX cu. in. were
on either side of the 58 hp mark, being that the bore was used it happened
that the larger bore engine had a slightly higher taxable hp than the
stroker.
My first car a 1300cc VW Bettle was around 12 taxable hp.

>>60-70 horsepower (in the modern sense. England used funny HP ratings in
those days (most likely for tax purposes) and I never have seen any
real correlation between modern HP figures and the old English ones.). <<

If was some theoretical hp figure based on the bore and stroke. Many
countries used similar schemes I think, but with different ways of
calculating it. You are correct that it was used for tax purposes.

All the best
