Hi everyone,
I thought I would throw this question out there and see what other builders think. I am finalizing the rear cooling tube design and wondering if it would be prudent to incorporate an EWP as an auxiliary pump to the mechanical pump.
After speaking with Davies Craig, you can control their 150EWP with a PWM signal so it makes it easy to add as little or much additional circulation to a cooling system. I am planning on using a PDM for electrical and the PWM feature for the brushless radiator fans. So I figure it is easy to incorporate an algorithm for an auxiliary EWP. Also, the mechanical pump can pump through an idle EWP so I guess there is really no downside.
I’ve read many of the EWP and overheating threads and it sounds like an EWP system with the mechanical pump removed works really well. And also, if a mechanical only system is designed well, it should not need an auxiliary EWP although there are a number of threads where an auxiliary was added to help with cooling at low RPM.
At this point, I do not want to disassemble the mechanical pump from The water pump housing. it is a supercharged engine and I need the housing for all the accessory pulleys. It’s a crate engine and also just don’t want to mess with it.
So anyway, looking for some opinions on this.
Thanks as always for the feedback.
