Richydehav,
Yeah BUT average joes head volume is going to be 0.3cc ish out and his squish 0.3mm ish out - alot in performance terms. Very very very few rotax engines measure up exactly like the big teams/ engine builders. BUT i bet nearly all the big teams there head volume is 0.01cc out and there squish 0.05mm out. Only big teams/ engine builders can do this. So the big teams will say oh my 50/50 sythetic castor mix has done that, but hey ho its not over the limit. I reckon at every superone meeeting a new head should be fitted by the msa. Then you will see the big teams/ engine builders going a whole lot slower. A sealership is a licence to print money!!
Oh and who has heard this before. If you hire one of my engines is about 0.1 - 0.2 seconds quicker. And in most cases it is - because it is coked up!!
