RX-8/RX-7 on the warpath!!!
This information is from nzoom.com of NewZealand. Reading the entire article makes it clear that the information is very credible. You may wish to read the entire article but the most important paragraphs are below.
Whilst Mazda's engineers are quick to deny that they will produce a turbocharged version of the RENESIS engine, principally because of the effect that process has on exhaust emissions, they do acknowledge that they are working on a supercharged version. This supercharged prototype is officially limited to 206kW, but produces an incredible torque, said to be some 375Nm at 4000rpm. Our sources also tell us that the supercharged version will in fact churn out 238kW, and in racing form will be easily capable of producing 298kW (400bhp).
There is also continuing but unsubstantiated speculation that Mazda is working on a larger-capacity, normally aspirated rotary to overcome the new engine's inherent lack of torque. Our guess is that if this is indeed the case, it will take the form of a three-rotor RENESIS engine. How a longer engine will fit into the RX-8 without raising its placement in the car is of course another issue.
________
206 kw=276hp
238 kw=320hp
298 kw=400hp
&
375nm=277lb-ft
_________
This kind of power in a 2800-3000lb car, as the RX-7 is likely to be, will be awesome!!
Honda S2000 and Nissan Z be ware, here comes the RX-7(?)

Cool, I just sold my third gen RX7 to a local buddy of mines that owns a place called Autotech Motorsports, in San Diego. His 3 rotor single puts over 450 rwhp on 14 psi but can easily be made for more. The car I sold to him is being converted into a 4 rotor single and should make well over 500+ easily.
By the way if anybody needs any repairs or any mechanical needs in the San Diego area, give these guys a call. Also have a dyno for wide band tuning. Oh yeah they also do autobody/painting as well. If you are interested in any generation RX7's give these guys a call.

If the RX7 ends up weighing less than 2900 lbs or even 3000lbs and puts out this kind of hp and torque it would be in supercar territory without doubt. Hopefully the Renesis engine has been updated enough that reliability will no longer be an issue. As far as the mpg is concerned, I don't really care.
The RX8 is heavier than originally anticipated because of the extra reinforcements in the doors due to the lack of a "normal" B pillar. The RX7 should not have any of this to deal with and with only two seats it should be light.
