Anyone used Butler's High flow water pump?
 

Butler has their water pump on sale, but it has no reviews on their site. Anyone got any input on the quality? I have my old one off currently and it's at least 5yrs old so figure I'd replace it and the divider plate.

I've changed the way I think about replacing known good parts. With today's QC issues if I know a part was functioning properly and there isn't a reason to replace it I usually roll with it. In particular a water pump. I've cleaned up a few and re-used them. Five years isn't that long for a part that's expected to last 100k miles.... Unless it has close to that much use I'd probably clean and reuse.

Not long ago I went through four new, very expensive water pumps until I finally got the version that didn't leak. Had a similar deal with an alternator.

I have no experience with the Butler water pump.

^^^^^^^^^^^^^^^^^^ This.

I've had the same experience, "If it ain't broke, don't fix it".

Likely the older part is in better shape than the new parts assembled overseas by 12 year old's, with poorly engineered, and machined parts................;)

This is the reason I will rebuild the OEM parts if it's practical over new/reman. If there's a problem I know exactly who worked on it, and who to blame........LOL

Looking at the pictures on their site, it appears to be identical to the CVF pump, but I have zero experience with either of them. The CVF has no reviews either.............:(

A friend use the billet impellar one, worked great.

Careful! That high flow might cause the coolant to spend less time in the radiator, and make an overheat situation!





Know that I am just kidding!:p:D
Mo flo = Mo betta.
I looked at those briefly last year. They look nice.

Zackly!

For best result at long idle, highway cruise, and accelerations;try to keep pump and fan speeds coordinated.

Simply; Factory pully ratios were likely optimal ( for some models). Seek 428, 455 HO ratios.

Complexity: low drag fans are desired to alleviate belts and water pump loads, so how to. Achieve idle and highway sync? Remained a challenge.

I start with the 6" crank pulley.

6” crank pulley? Even the smaller AC water pump pulleys are 6.5”. A underdrive will be more likely to run hotter in long idle stop and go.
