haha - no problemo...I might first try my hand at the EGR solution although I'm going to have mega-fun reprogramming the MS to handle the control of the EGR. If that doesn't entirely work, then I'll pull out some water injection.
I am keen though to know what people think about the conrod/stroke ratio and it's effect on peak combustion pressure/temperature - would it be noticeable enough to be a consideration in the design?
