Jeff,
John is going to machine the pistons and add an extra spacer to each cylinder to lower the compression ratio.
Heat is power's enemy, and if we don't twin plug the car, or do what Wayne has suggested, then a lower compression ratio will make the engine more powerful as there won't be any excessive friction and pre-ignition.
Wayne,
I only use 98-octane fuel. Can you tell me more about the electromotive distributor-less system?
