Jim...I've read that for each additional point of compression you
might see approximately 3% more power.
For reasons unknown to me, the 1976 Federal Spec Spitfire came through
with compression *increased* to 9.0 to 1...up from the 7.5 to 1 used
the three years before and in all later years.
Comparing that car's performance to the dual S.U. UK version should
give you your answer.
