Electric Water Pump / EWP Davies Craig

How much weight and hp are true gains, if any

I measured about 2lb net weight savings.

I didn't back to back the HP but I feel fairly confident in the say 4 - 8 hp range. Higher at higher rpm. Meziere claims 8-10hp and I think I saw some reference to the Hot Rod coyote testing reporting mid single digit savings with their electric pump on the engine dyno. I also based my results on my total resulting power with cams to others with cams and high RPM intake manifold.

I am debating on it. I'm building my car for more of a mountain/ weekend car, and idk if it's worth it.
