Hi : What is the optimum waterpump rpm for the 13B as i can modify the pulle=
y diameter and ratio=E2=80=99s for my set - up
The data i have is that at the standard ratio is 1:1.18  at 6500 rpm for the=
 13B the pump flo is round about 150 - 160 L per minute.
So my question: If i run on 6500 rpm for take off then the waterpump impello=
r turns 6500 x 1.18 ???
Must i put on a bigger diameter pully on the pump for a flo of round about 1=
00 L per minute.?
Don=E2=80=99t know  ?

If somebody can help me with that

Regards Le Roux
