Looking at Bosch they have a couple of pumps like this and yea they say it’s for the big turbo/supercharged engines. :) I got mine off a 01 Cadillac CTS and the 03-04’s have a bracket built on to the pump. I plan on using it in my race car it’s a 1975, 1200 Honda Civic. It has 13.4-1 compression, up...

THANKS for the info!
I have this Bosch pump, PN 392020034 or GM PN# 90448289 it's been knocking around in my tool box for years waiting for me to do something with it.
I will do some more research to find the amperage draw.

DAUGH!
I read that thing over three times, dont know why i didnt see it!

oh well such is my life, cant see the forest through the trees

But you dont remember which pin you are useing?

As I was discussing with Martin about running an electrical water pump, he is using full switched power. I would like to run a pump with the PWM Duty Cycle, say 5% at start up and then to maintain a running temp of 160*F/71*C I have an S60Pro, soft ware 46 Has anyone done this or am I just hopping i...

Hi Martin,

Sound like it will do the job

Now I just need to figure out if I can run my pump with the turbo PWM.

I cant see why you would need any flow (other than natural convection) whilst the engine is warming up. It should warm up quicker anyway with no flow and once a preset temperature is realised, say 65 degrees then I intend to switch on the pump. I know the water temperature might initially drop but ...

I was afraid you were going to say that :| So should I start a new thread to see if someone has run a coolant pump using the PWM for controlling the water temp. I would think that you would want to have some flow before you have reached the preset temp of the sensor turn on the pump? If you could wi...

After reading and re-reading, question...
Are you planning on using the PWM circuit used for the turbo waste in AUX2?
As I am also looking to do the same but want to rum my pump PWM'ed.
Second, looking at the manual, this could be done with my S60...correct?

So its all possible

but a 12v trigger could short and start a fire. I turn everything on with switched ground when possible. They figure if the power wire gets shorted to ground the fuse would blow before any "melt down" would occur. As far as me, yes I also wire my relay switches “ground”. It’s easier for m...
