Hi guys

The pumps that I am aware of are:

I do n= ot remember the pulley size on our alternator. I can remember ordering it f= rom the Eastern States of Aust.=C2=A0
I=E2=80=99ve put it on my t= odo 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 w= ater pumps I=E2=80=99d go with electric and get the benefits of modulating = the pump speed for automatic temp control at cruise.
The cowl fla= p gives some control but it can still get too cold in cooler weather.

Cheers
Steve

Marc

On the = Renesis I=E2=80=99ve put a race pump on to =E2=80=98reportedly=E2=80=99 red= uce cavitation as the basic 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 on one flight tamper went up considerably and I reas= oned 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 slowe= d my alternator with a larger pulley.

Hi : What is the optimum waterpump rpm for= the 13B as i can modify the
pulley 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 6500 rpm for take off then the waterpump impel= lor turns 6500 x 1.18 ???
Must i put on a bigger diameter pully on the p= ump for a flo of round about 100 L per minute.?
Don=E2=80=99t know =C2= =A0?

If somebody can help me with that
