OPS Super SPA - absolutely amazing work of machinery!

Perhaps my all time favourite engine if not the most powerful today - simply because NR and YS have forged ahead with recent developments in RE classic engines. The pipe really ought to be used with the engine as it is a slip fit in the adjustable tuning header allowing the engine to be tuned without having to incrementally cut the header.

Below is my classic re-design for this engine... One day it will be built!
