Hp loss to water pump?

658 Views 5 Replies 5 Participants Last post by  TBT-Syncro
Does anyone know or have an estimate of how many horsepower the water pump steals from the engine in high revs due to paracitic drag?
I mean, if the G-lader takes 17hp, the water pump has got to be using some, too.
Is there any reason power-wise to get an electrical water pump, or is it to much money and too small power gain?

somebody read my post in the $4k topic. its not worth it unless you are building the most power hungry motor out there. because if you mess up say good bye to that expensive setup. I'd say 5-6hp

5-6 hp?
What are your guesses on AC and PS?

ac not much when it isn't on ps may be the 6hp

PS deffinately robs power enough to notice in my winter beater haha

typically on a 200hp motor (approx) switching to underdrive pulleys will give back 4-10 hp. So it's reasonable to say that you are gaining 2-3 hp per accesory, and that this is at best/worst 50 % of what they take to run. So by this bubble gun scenario your water punp takes 4-6 hp to work..... but it all boils down to the quality of your flux capacitor.
