Interest in 6.7 / 5.9 performance water pump with a billet aluminum impeller and better bearings?

[Tuesdak]

Any interest in a performance water pump with a billet aluminum impeller and possibly better bearings? If so please contact FlowKooler and ask them to put your name on the waiting list (after mine, of course). Interest in a specialty product will be the only way they put one in production esp. with Red China's mainstream low cost import water pumps.

Are you, like me, questioning a fragile composite impeller that, from other posts, can't even survive shipping? A close look at the little pulley size of the water pump driven by the large Cummins crankshaft pulley would suggest why Cummins Water Pump Bearings are known to fail often vs. other makes. It simply spins many more times per mile than other makes using the fixed life of the bearing up faster. (Why yes, the new with the engine rebuild Cummins water pump of mine just failed my inspection with the belt off due to "Thunk-Thunk" bearing slop.) Yes, it's a simple job on a Cummins vs. the usual remove the front of the engine with everything the OEM could get hooked to it: bolted to the water pump in a very specific order...

I could go from a Cummins 5.9 five (5) blade water pump to a seven (7) blade 6.7 water pump for performance, BUT: composite impeller. My specific interest is using Evans coolant that doesn't hold the same heat as water so a 7 blade pump appears to be an upgrade for my No-It-Is-Not-Stock 5.9.

So I called FlowKooler and bluntly asked them: "if you make a performance water pump for a GM 6.2/6.5L IDI diesel... Why don't you make one for the 5.9/6.7 Cummins in pickups? Yes, I also would like a better bearing please!" Simple answer: "It's calls like mine that gets stuff made. The manufacturing hold-up will be finding out if there are potential customers willing to pay more for a performance pump vs. the Red China import pumps."

A fairly recent thread sums up the current Cummins 5.9 and 6.7 water pump offerings:

If there’s one out by the time I need one again, I’d consider it. Not crazy about an aluminum housing though.

I’ve sent a message through their site.

I would assume like their other products: Standard OEM like cast iron housing, but, billet "anodize surface coating" aluminum impeller.

Definitely interested. I emailed them. Thanks for the heads up. I am on my orig pump at 148K so I may be in the market soon.

Considering that 6.7 guys who are deleted and running higher rpms switch back to the 5.9 pump I am not sure it’s needed. The increased flow of the 6.7 pump is for the EGR cooler.

And thus a "performance" pump is already on the market and available leaving the question of a better bearing design and better aluminum impeller design up to FlowKooler.

In my case a specific advantage to a 7 blade pump is for the Evans coolant I am using. When the system is "dry" because the engine was replaced or overhauled it's an easy switch. Supposedly less corrosion and a 0 PSI system. The disadvantage of "No Water" is: Water has a specific heat capacity of 1.00. It transfers heat more effectively than any other fluid, and is therefore used as the reference fluid in the scientific measure of specific heat capacity. Comparatively, the specific heat capacity of the various glycol solutions in the Evans products ranges from 0.64 to 0.68. So they hold less heat than water... Of course one doesn't run straight water in most cooling systems. So a 50/50 mix and antifreeze will drift the recommended coolant capacity away from the 1.00 "Water Only" number. Water Wetter products for example have the best cooling results on straight water and smaller benefit numbers with a 50/50 mix.

I also have that 'coolant' (water) cooled BB Garrett turbo.

Because I need a water pump sooner than one of these can be made I called Geno's and asked about the '89-'12 Cummins pump as it lacks a website picture of the impeller. They went and looked for me and it's a 7 blade composite impeller.

I am not sure marketing would want a "low performance" 5 blade style pump as the trend is going to the 'one part number fits all' and that would be the 7 blade design...

I just ordered one for mine.
