But while the rotary engine promised many things, torque was one thing it failed to deliver. That's what makes this RX-7's power output so incredible. Using a four-rotor engine instead of the ...

Starting with the 717C in 1984, engineers employed a 1,300cc 13B rotary engine sourced from the RX-7. The modified 13B produced around 310 hp at 9,000 RPM and had underwhelming results on the track.

There is a caveat with the RX-7 though, as with all rotary-engined Mazda ... with both 5-speed manual and sluggish 4-speed automatic options. The engine itself was based on the one used in ...

Through the history of internal combustion engines ... rotary forums shows people rebuilding somewhere between 50,000 and 100,000 miles. However, this all must be taken with a grain of salt. The ...

And though it’s true that the RX-7’s rotary engine can need a rebuild in as little ... while the C111-II had a 0-62mph time of just 4.9sec. However, even Mercedes’ engineers couldn’t ...

the term is much better known as a nickname for the Mazda RX-7 — one of the few cars that used a Wankel, or rotary, engine. If you ever wondered how these worked, why not print a model?

As a result, the 0 to 60 mph sprint was cut to 4.8 seconds ... Just make sure to learn these things about the rotary engine before buying an RX-7. Alongside the Spirit R range, Mazda also ...

This paper considers the sensitivity of an open-rotor engine to variations of three operational parameters during take-off, focusing on both aerodynamics and aeroacoustics. Via a sensitivity analysis, ...

The PropNoise simulation tool predicts the noise of turbofan and open rotor engines. All sources and effects of noise generation can be fully described analytically with PropNoise. The tool offers the ...
