Default Killer B Motor Sport High Flow Water Pump Housing

Well, I been looking for reviews on Killer B Motor Sport High Flow Water Pump Housing for long time but I have not find anything. If somebody have bought this part and got good results I would like to know.

This is the link from Killer B Motor Sport High Flow Water Pump Housing.

http://www.killerbmotorsport.com/ind...gsandTurbo.htm


I have installed their oil baffle and oil pickup and here are plenty reviews on this 2 parts but on the High Flow Water Pump Housing I don't find anything. I am looking into buying this part to increase the cooling capacity on my STI. I already have a Koyo radiator but thinking about better water flow to eliminate the bubbles will make it better since the OEM Water Pump Housing is kind of small on modify engines. If somebody did the installation on this and can provide results please post.

I have one. Make sure it comes with the new bolts. You can't use the stock ones. Also, you need to fab up or find a new hose...

Any improvement on cooling efficiency? Looking to install that on my STI to improve the cooling system, right now I have installed the Koyo radiator and Cosworth thermostat but if that will help to improve the water flow that be awesome. Supposedly according to Killer B site it will reduce the cavitation flow.

No idea really. I did it with a pretty major build. New everything.
I got it because The motor needed to spin pretty high under boost for a long duration and I figured it could only help.

If you get it, make sure it has the new bolts. If you're running anything but a stock radiator (even still I don't think the stock hose will fit then) prepare to spend some time hunting out a hose to connect the outlet and the radiator...

So what hose did you end up using?

I am in the middle of the install, yet I can't seem to get any of the OEM hoses to fit? I'm trying to see if modifying them will work, but this shouldn't be this hard, I don't understand why they didn't provide the hose, if it turns out to be a custom one?

I ended up cutting up two stock hoses and using a metal tube to link them. This would be a lot better if they would give an idea for a proper hose

That's a great idea! Although it sort of reduces the advantages of having better flow, as now you are necking down the flow with that extra tube...

By the way, was your housing also more horizontal than angled down? I had to trim the fan surround in order to make the hose fit?

Mine is horizontal. I didn't have to trim anything but I'm using a Ron Davis radiator...

Whats the verdict on these for a race engine? They look good but do they actually improve flow?

Sorry I missed this... 3 years ago

These are for high RPM applications when aeration on the suction side of the pump can occur; where RPMs are regularly going to be +6,500.

Just ran across this post. I noticed that the new one is cast aluminum and they said the hose fitment is easier.
