Hi guys

The pumps that I am aware of are:

= I do not remember the pulley size on our alternator. I can remember orderin= g it from the Eastern States of Aust.=C2=A0
I=E2=80=99ve put it o= n my todo list to measure when I=E2=80=99m at the hangar, possibly Sunday.<= /div>

If I could be assured of the reliability of the= latest water pumps I=E2=80=99d go with electric and get the benefits of mod= ulating the pump speed for automatic temp control at cruise.
The= cowl flap gives some control but it can still get too cold in cooler weathe= r.

Cheers
Steve

Steve,

Marc

On the Renesis I=E2=80=99ve put = a race pump on to =E2=80=98reportedly=E2=80=99 reduce cavitation as the ba= sic pump is reported to cavitate at the rpm=E2=80=99s we operate in during= take off.
When I took out a restrictor in the return to the radiator o= n one flight tamper went up considerably and I reasoned this was caused by= cavitation.
In response I purchased a race pump from New Zealand.

My water pump is running at OEM speed, but I slowed my alternator wi= th a larger pulley.

Hi= : What is the optimum waterpump rpm for the 13B as i can modify the
p= ulley diameter and ratio=E2=80=99s for my set - up The data i have is that= at the standard ratio is 1:1.18 =C2=A0at 6500 rpm for the 13B the pump flo= is round about 150 - 160 L per minute.
So my question: If i run on 650= 0 rpm for take off then the waterpump impellor turns 6500 x 1.18 ???
M= ust 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 =C2=A0?

If somebody ca= n help me with that
