EGR as you state does NOT produce power or heat, it is the inverse to that as you are limiting the amount of oxygen and therefore fuel in each chamber so "ultimate heat" and power go down not up.... it's a temp control thing and emissions thing not a power thing.

Same applies to water temperature.

Running a rotary at 90 deg C+ reduces HC, it also reduces power (proven fact).

It does not matter if its a Aixro go cart rotary or a Mazda R26B 4 rotor these engines all and in between make MAXIMUM power from 65 deg C to 75 deg C.

The key is density increase in aspirated volume, and the correlation to reduced knock events is directly proportional to the lowering of HEAT (in the air, the block etc) not increasing it........ though through the effect of combusting more stuff we do get higher end heat in the chamber..... there is no lack of heat in any rotary engine as I listed above. What there is a lack of is control of the end heat and where it is put into and this is why water injection is the #1 rotary engine modification when looking boosted applications.

Every year goes by and I run more and more water injection, and so do my customers, there is good reason for it, unless you are actively testing this and from every angle and verifying it with performance figures and long term durability tests then you really are doing nothing more than hypothesis based off very limited information be it first hand or recycled.
