As our displacement gets larger and we produce more heat from this high performance engines could we possibly benefit from a porting and polishing of the water jackets.

I noticed that when I took my cylinders out this week how rough my water jackets are.

Of course the openings are small so it would need to be done pre-sleeving.

To what coefficient?

More than a faster flow of cooler coolant?

Just thinkin out loud. I doubt it would be worth the trouble.

Porous metal should actually dispell heat better than polished metal.

agreed, although not by much the porous metal would have more surface area to dispel heat. i would think it would be the same principle as an air-cooled engine where the "fins" give more area to dissipate heat.

I don't think (could be wrong) that polishing the water jackets would increase the speed of flow as I don't think that the water is restricted by it. If flow is equal the porous surface represents more surafce area.
2 cents.

Yeah I checked it out, looks like a clean, sweet setup. I wasn't going to call dibs or anything until I sell my paddles. I've had a hard time selling. Sooner or later I will just have to break down and buy the carbs outright.
