Paul,

You said...."the RX8 engine has somewhat lower exhaust temps" .  Precisely, how was 
this achieved?  One would think with the engine turning higher RPM s  to 
make the extra HP the temps would be the same or higher.  Please expound on this.

I think they delayed the exhaust port opening and recycled some of the un burned 
hydrocarbons that were burning in the exhaust manifold. I also suspect a bit
more of the exhaust heat is going into the cooling system because of the
side exhaust ports.
