Blower & pully difference question

I have read somewhere that a 5% od pully on a 93 engine would yeild a %5 overdrive, but on a 94 - 95 engine would yeild a different ratio.

a). did I misunderstand what was being said or

b). is there a difference in drive pulleys from engines?

Tks.

The 94-95 M90s use a slightly larger pulley because they are more efficient than thier 89-93 counter parts.

94/95 3.250
89-93 3.135
5% 2.950
10% 2.850
