"support america" this is why I really dislike people trying to bash Rotary's. They often make it a "well american muscle cars are made like this, and we are american's dammit!" What bull. Some how a type of internal combustion engine is more american than another??
This idea and thinking clearly leads to new developments and better technology right? I mean, as long as we keep improving the pushrod v8?? is that how it works??
Far as I'm concerned I'd really like to see the Rotary come through as a good engine, I think it has plenty of capacity for it. Just need to improve the cooling. On the Renesis the third "shared" exhaust port gets all sorts of rediculous hot, the other two exhaust pipes can be peachy and the third will be red hot.
As for development, I'd also like to see a quasiturbine engine to pull through and make it into cars or buses...whatever the application it'd be pretty cool.

Daytona Rolex 24hr: SpeedSource RX8 wins GT class
Read below enough said:
SPEEDSOURCE CASTROL SYNTEC MAZDA RX-8 WINS GT
CLASS AT 2008 ROLEX 24 AT DAYTONA
- 22nd Win in Endurance Classic for Mazda since 1975 –
January 27, 2008 (Daytona Beach, Fla). After 24 hours of close competition among 41 cars, the SpeedSource Castrol Syntec Mazda RX-8 team won the GT class at the Rolex 24 at Daytona to kick off the 2008 GrandAm season. The SpeedSource driving team of Sylvain Tremblay, David Haskell, Nick Ham, and Raphael Matos started from the pole, and led 323 of 664 laps, on their way to ninth overall and the class win.
The SpeedSource Mazda team beat the runner-up Porsche by over five laps. The win was the 22nd class win at the race for Mazda and a ended a lengthy winning streak by Porsche at the biggest 24 hour race in America. Along the way, the SpeedSource number 70 car beat over two dozen Porsche 911 GT-3s, a handful of Pontiacs, a pair of Ferrari 430 Challenges, a Corvette, and a BMW M6. There were a total of 55 lead changes among 10 cars in the class, but no onecould pass the RX-8 for the final 185 laps.

Not a rotary hater, but it grinds my gears when people claim that rotaries make "all that horsepower out of 1.3 literzzz!!!"
Read and know:
"While a four-stroke piston engine makes one combustion stroke per cylinder for every two rotations of the crankshaft (that is, one half power stroke per crankshaft rotation per cylinder), each combustion chamber in the Wankel generates one combustion stroke per each driveshaft rotation, i.e. one power stroke per rotor orbital revolution and three power strokes per rotor rotation. Thus, power output of a Wankel engine is generally higher than that of a four-stroke piston engine of similar engine displacement in a similar state of tune and higher than that of a four-stroke piston engine of similar physical dimensions and weight. Wankel engines also generally have a much higher redline than a reciprocating engine of similar size since the strokes are completed with a rotary motion as opposed to a reciprocating engine which must use connecting rods and a crankshaft to convert reciprocating motion into rotary motion.
National agencies that tax automobiles according to displacement and regulatory bodies in automobile racing variously consider the Wankel engine to be equivalent to a four-stroke engine of 1.5 to 2 times the displacement; some racing regulatory agencies ban it altogether."

I both agree and disagree with the displacement nomer on the 1.3 liters. It does create significantly more power for it's size. However, it's hard to compare. Much like the Quasiturbine which can have like 32 strokes per cycle, all dependent on how many ports and carriers you put on it.

i just hope those who hate rotaries keep it that way... its getting hard to find a nice condition FC now adays cuz ppl keep crashing or blowing them up..
i have a DD FC btw, bought it in 04 w/ 50k miles... its at 141k now with normal routine maintenance and the only thing that has gone wrong is... well my u-joints failed on me... but thats not engine related.... i think its great for what i do with it (freeway 60+ mile commute) because at that speed *3k* the motor is only spinning at a third that... so its almost idling comparing to a car
the RX8's motor is loads better than the 13bs because its almost to the power levels of the 13bREW but also classfied as a ULEV... and that was the main point of the rx8 was to prove to everyone that it can be emissions friendly too... i'd get one.
and where are the pix??? i wanna see more of the rotary nc not to see a big debate

I think I have owned eight rx7s and never had an engine fail. But they can be a pain, especially compared to the miata. And when I had the choice between my 91 turbo miata and my black 94 FD touring with 47k, I drove the miata. Selling the FD for $7k more than I paid was handy for the family stuff. I am getting some funny feelings about getting another one though. I loved my black 89 turbo, bought as a shell, new most everything, added a back seat and took a vacation with the family. Good times. Only made a little money on that car, though, I through in the labor for free.

I have also driven an 87 turbo that had 199K on the original engine. But one day, my 84 gsl-se just started smoking, still ran great for some time but annoying. Rotaries are very reliable when driven but don't sit well. Then you have to either put atf down the carb, pull it with a truck and pop the clutch in second, or arc the distributor (rubber gloves are good) for some starting power. All fun.

Not meaning to crap on your thread, Ben. That's a kickass project you have there and I wish you much luck with it, that's got to be a helluva lot of work and dedication.
