Someone posted this a while back and I grabbed it.justjoe001 said:I remember seeing a great chart on this but can't find it. I will keep looking. I remember the reduction in rpms averaged like 400 -500 rpm per gear. Or something like that.
Is this what you were talking about?
Disclaimer: I haven't look at this chart very close nor have I done
the calculations to see if it's correct. I just screen captured it and saved it.
