Hi Gordon,

Ther are a lot of things one can do generally speaking. Increasing compression ratio by reducing trapped volume and re-shape cylinder top may give you a beast to tame. This activity is for people with special knowledge. Timing will also play a major role in this, low timing gives a torky engine, high timimig gives you a reving engine. But we are now at a certain distance from a friendly everybody's engine.
By increasing compression you may also get an engine that need redesign externally because of excessive heat. Total heat= compression heat + combustion heat.

I think MTK et al are doing the right ting by reporting a set-up that are for everybody that want a gasser.

Best regards
