- The other problem was heat. The combustion area of a rotary
- never experiences intake cooling, so you get uneven heating which
- becomes a bigger problem on the 4 rotor and 3 rotor units (how
- you cool the "inner" units adequately...
-
- But a 3-4 rotor would be nice as an alternative to the twin
- turbo's...
