renesis rotary
I'm posting from Texas and have a question about the new mazda renesis engine.It's just been released here in the states(three weeks ago
in the new rx-8)and is already becoming very popular.It's 1/3 smaller and lighter than the 13b and makes 250 hp! all this and naturally
aspirated!I've seen an artical of a guy with a very nice dax rush who's already running one in his car. How did he get the thing so soon?
Were they released there earlier? Mazda will not sell the engine by itself for one year due to production shortages and nobody seems willing to wreck
their rx 8 for me.Any clues?

He probably had someone at the dealership that was willing to get him one.
They seem to be a good engine, but the engineers stated that the power will become extremely unreliable above 400HP, where the 13B would support 1000+

Is that because it's designed for N/A instead of the 13B's forced induction?
Autocar mag in the UK recently ran a story on the next gen RX-7, stating that inital versions would be 1.6 300bhp N/A and a supercharged version is
being worked on too. That would presumably point to the 400bhp reliability problem being in highly stressed N/A trim.
All speculation of course, but does anyone have any more information?
Cheers,
Neil.

Ok, I will find it...
(NOTE: my information is "american" so likely the UK and Europe version will be much better suited to everything...)
what Sports Car International says is that the lack of (extreme) tunability will come from the ports being moved from the outside of the rotor
housing, to the side of the housing.
This was done for emmisions purposes...
But ultimatly, who would need more than 400 horses in a locost!!?
(note USA/CAN cars are 250HP for the "high power" version and 210 for the "normal power version" Hummmmm....)

Hicost has > 400bhp in his Locost  And I think that's without nitrous, which it has also. Cossie engine.
