These will also work for you truck guys. We just may need your cores I have located a couple but may need more if the demand is that high.

Evans Cooling Systems Inc has just released a new highflow LS1-6 water pump. The billet coolant pump and pulley flows over 20% more than stock and changes the cooling pattern for a more even cooling. The pump increases cooling efficiency in modified LS1 Corvettes, Camano’s and LS1 based motors. Evans has changed the design of the OEM pump casting and includes a billet pulley hub and heavy duty 3/4" shat bearing assembly. It also includes a 3.8" OD 8 vane scrolled impeller to reduce parasitic horsepower loss at high RPM. A new serpentine belt is required.

How is that these are of the car ones but they are doing some truck ones for me.

Hey Nate

I fixed the links, for some reason they weren't pointing to the attatched pictures.

When is the GP over?

I might get one for a motor I'm working on.

 

Nate
Are they're any noted horsepower gains with this pump setup ?
I've heard the npg stuff in pretty good just wondering if it's going to be worth the $480.00 to get the system running ?

 

A search dug up this old thread. I think I'll be adding an Evans pump and waterless coolant when I do the heads/cam/meth work in the spring.

I'm wondering if I could/should use the waterless coolant in the Radix intercooler?

 

What is the benefit of going with one of these over an electric water pump since it robs parasitic hp from being belt driven and the electric ones just draw off the battery for the pass down teh track or you can short belt it either way. Just trying to justify the cost of one of these when a e-pump can be had for a 100 bucks cheaper and not rob hp from being belt driven
