Flowkooler designed a high flow water pump for the 260 Ford engine used in the Mark I Sunbeam Tiger. It has a CNC machined billet impeller with 16 vanes, integrated shrouding and a reduced casting-to-impeller vane clearance.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Ford engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

Short History of the Blocks 

The 221, 260, and 289ci engines lived side-by-side during 1963. In 1964, the 221 was dropped, leaving the 260-2V, 289-2V, 289-4V, and 289 High Performance engines in production. In 1964, the 289-4V engine was a low-compression V-8, just like the 289-2V. It ran on regular fuel and was available only in the Mustang.  In 1965, Ford dropped the 160-horse 260-2V, leaving the 289-2V as the standard small-block V-8. Ford also increased the 289-4V compression ratio with flat-top pistons which boosted the horsepower rating from 210 to 225. The 289 High Performance V-8 remained the same through 1967.

I am stunned
Color: Black, Size: Queen(20x30)
I had no idea what to expect from these. But for as cheap as they were I was willing to just write it off of they weren't that good. I had already picked up a new memory foam pillow to replace my previous memory foam pillow that didn't do well with dissipating heat. This new pillow was fine by itself, but when I put my pillowcase on it, the properties that made it cooling were negated. I'd get a bit of sweat on the side of my head or my neck where it was against the pillow all night. The pillow was supposed to be a cool one, but the pillowcase was not. So I grabbed this set. Smooth, no loose threads anywhere, stitching and seams are all spot on. And it's smooth to the touch. Got it on the pillow, and as soon as I laid my head down on it, I could tell immediately that this was going to be a different result that my other one. Not nearly as warm even after laying on it for a while. No heat buildup, no bits of moisture on the skin after being on it all night. This definitely works well, especially with my cool sleep pillow. Now I can have a far more comfortable nights sleep. For the price, it's a steal. I have no idea what longevity will be, but with two of them, I'm sure I'll get more than my money's worth.
