How to read a turbo chart..

[IveBeenBad]

there is an error on C15 in the equation.

also, the number of cylinders MUST be four, or it will be inaccurate.

for example, if i put in 8 cylinders, the equations are only half of what they should be because of the dividing by half the number of cylinders, instead of 1/2 RPM

So it should be RPM divided by 2... one sec and ill update it.
