What did the 787B rev to?
Even the 24 Hours of Le Mans-winning Mazda rotary racer, the 787B, spun only as high as 9,000 in race trim, where it made over 700 horsepower. Some claim 900 was possible if the engine were allowed to spin to 10,500 rpm, but neither of these figures compare to the 18,000.
Why did the 787B get banned?
The rotary was only banned because of rules that where already in the making. To be honest the 3.5L rule was supposed to be implemented the year of it’s victory, but the 3.5Ls where proved unreliable causing the the teams to switch to last year’s cars.

How high can a rotary engine rev to?
The maximum revolutions of a rotary engine are limited by tooth load on the synchronizing gears. Hardened steel gears are used for extended operation above 7000 or 8000 rpm.
Why do rotary engines rev so high?
The secret to the high revving nature of rotary engines lies in the fact that all of the moving parts are rotational rather than reciprocating. Stress and valve float become an issue when reciprocating masses are high, such as in pushrod engines with valves and pushrods constantly changing direction.

Can a rotary engine run on diesel?
Wankel rotary engines have been developed to run on pretty much every fuel you can imagine from alcohol to diesel through to gasoline, kerosene, natural gas and even hydrogen. In simple terms though, if a piston engine can run on it, then a rotary can too.
Are rotary engines better than piston?
They consume more fuel while generating less horsepower than piston engines. And because they are prone to leakage, rotary engines also produce more emissions than piston engines. On the other hand, rotary engines have fewer moving parts.
Is it good to redline a rotary engine?
A rotary engine is perfectly fine to redline and even drive at redline.
Why can’t pushrod engines rev high?
Most pushrod designs feature two valves per cylinder. Without extra valves, the engine can’t take in enough air at higher rpm and it becomes starved for air. Thus, it can’t rev as high.
