Would be cool, but copper crushes and doesnt really spring back. So with expansion and contraction of the motor you would always have leaks.

 

yeah but you guys get my idea. it would need a little help to come to life .but when you think of the applications it would be awsome , then the only weak point would be the side seals. because the apex seal problem has already been addressed my rotary aviations

 

Read up a little on Banzai's nuclear o-ring coolant seal debacle to get your answer on why not

Short story is coolant seals dont fail during normal use. They fail because something went wrong. You are better off spending the next to nothing available seals cost, and put the money towards actually fixing the problem, not trying to fix the symptoms.

 

No O-rings, just silicone.



Fill the cooling passages with concrete.



Drag only, of course, but then drag cars only need to run for a minute at a time tops.

 

Update, sort of...

If you look closely at the side of the rotor housing, you will see that the chrome insides are inserted into the aluminum housing, I have thought of this idea and it is impossible unless you create an insert yourself to exact mazda specs. I dont have the time and while thinking about it, you will spend more money through trial and error, instead of buying new ones.

 

Actually, the aluminum is cast around the steel inserts.
