This idea to machine trailing plug holes bigger to get more out of the trailing spark is like buy a bigger wing so you can fly faster. The blowby thru this large hole is going to make the engine run extremely ruff. You will ignite the fuel in the intake face of the rotor, when the apex seal is passing over the trailing plug hole. Mazda made this hole small for that purpose. I have 17 years of experience working whit the rotary, and doing this mod is one way to destroy a nice rotor housing. /Martin ---------------------------------------------------------------------------- ---- > Much as it breaks my heart to have to do this....... > Trailing plugs machined to full size (same as leading plugs)
