LOL, good point!


Sadly though, personally i wont EVER know the whole equation when it comes to engines, as thats the nature of learning mainly from doing things, a lot of the decisions you make you do so subconsiously without REALLY understanding the maths behind them, you might know some of that theory, but never the whole lot.

I do not have access to any books that give me enough data to work out the optimum CR for my engine, so the fgure of 8.25:1 i have come up with is basically my "best guess" based on other engines, i like to feel its an educated guess, but it IS still a guess really.

Without a budget of millions of pounds to build dozens of these engines and throughly test them i have no choice but to settle for an approximation to the best solution as its beyond my means to get the perfect solution!
