I know a water jacket mod is the ribbing the rotor housings, and it creates more surface area for the water, and creates turbulence to cool the combustion chamber. But I've never seen it. Are there any pix anywhere. I've search for 3 hour and 20 minutes. Here, the other place, and google...

^ That looks like a lot of work.

there. It looks like it takes for ever, but they only charge $90 that's an hour of shop labor I wonder how they do it? I'm just going to cut the **** out of my housings and hope it works! LOL!

I would be careful with just hacking up your housings. Try on a spare one first I know you have them Get down a techniques and then have at the ones that you are going to put your engine together with.



I personally would use a small diameter dremel tool that has a wide stance. I think that would work the best.

Nar a piller drill with a round Carbide Bur works the best.



You can set the drill at difrent levels and you just run move the housing to cut your groove. Alot quicker.

Ahhhh I see what you mean a carbide ball on like a drill press. Welp dremmell it is... LOL!!!

Does this mod actually give results?



I understand the concept behind it, but have always wondered why the cuts do not go parallel to the water flow. Seems like there would be less resistance and therefore less turbulence/cavitation in the water passages.

Hyper4mance2k

the turbulance allows more water to be in contact with the housing there fore more water to remove heat from the housing... I've heard nothing but positive results from it. If you search you can find a bunch of positive results, but there's never any pix cause the threads are usually from 2002.

rezcar. Imagine that you have laminar flow through the passages. Essentially all that water would not be mixed, sure the coolant on the edges would be cool but right in the center it would still be hot. Make sense?
