Re: Daily driver: which electric water pump?
And therefore the motor is now somehow working harder to spin the alternator the same RPM?!
please explain.
I don't see how if you were to spin the EWP at double speed effectively equaling flow at higher RPM that you'd dyno the same since the alternator still is spinning at the same speed regardless. This was put up as fact way back when this thread was new.
I'm honestly trying to learn. Educate me.
My main question from all of this is:
If the reason for the hp increase is due to the lower flow of the ewp, but the alternator takes the same power off the drive belt with or without the EWP how does such a statement make sense?
The crank still spins it the same speed with the same resistance.
How is an EWP and alternator pulling more hp off the belt than the same alternator that ISN'T powering an EWP?
please explain.

If you actually read my initial post you would see that you are wrong. I was asking FROM THE BEGINNING to have it explained to me. Neither of you explained what effect the alternator has on the serpentine belt. You ignored it and went on about other things.
In fact every single post I've made asked the same question. And asked to be informed.

The electric power consumption in watts is the voltage times the current. So at all times, the electric pump requires the same number of watts from the alternator. For the alternator to produce those watts has little to do with the RPM of the alternator. Its a function of the mechanical efficiency of the serpentine belt drive system, and the efficiency of the conversion of the mechanical energy supplied by the serpentine belt to electrical energy in the alternator coils. The inefficiency of the conversion is in the form of the heat rejected by the alternator coils.
With all the insults and personal attacks you've posted, it might be a good reason for a ban.
Let me think about that.

Re: Daily driver: which electric water pump?
Your explanation wasnt helping. Which is why I kept asking. I clearly don't understand electrical stuff. I needed a lay mans explanation.
You guys want to hold that against me and call me stupid or unable to comprehend?

Re: Daily driver: which electric water pump?
You pull up an old thread, with a chip on your shoulder, challenging people, DEMANDING explanations. You post totally incoherent questions. I was extremely patient with explaining the issues. You either chose to ignore the explanations, or have a reading deficit disorder. You have a serious problem, and now you are upset because people defended themselves.
You opened this up with the clear intent of starting trouble, and you got it after you persisted with your inane questions.
This whole thing it being closed, thanks to you.
