Is it bad to redline a rotary?
A rotary engine is perfectly fine to redline and even drive at redline.
What do rotary engines redline at?
Gasoline automobile engines typically will have a redline at around 5500 to 7000 rpm. The Gordon Murray Automotive T. 50 has the highest redline of a piston-engine road car rated at 12,100 rpm. The Renesis in the Mazda RX-8 has the highest redline of a production rotary-engine road car rated at 9000 rpm.
What does the RX-8 redline at?
If you relish high-revving power over low-rpm grunt, the RX-8 might be for you. Its 1.3-liter rotary engine's redline is 9,000 rpm with the six-speed manual transmission, and it makes 232 horsepower at 8,500 rpm. Both of those rpm levels are incredibly high for any production-car engine.
Can you over Rev A rotary engine?
What Happens If I Rev My Engine Too Much? A valve train can be damaged by over-revving if it stays open for too long, causing it to malfunction. ... In a valve float, the valve is stuck between two openings. There will be a loss of power immediately as a result.
Do I need to redline my rx8?
If you DON'T periodically redline you will definitely have carbon choking problems, so redline regularly to be sure that you aren't deliberately causing problems.
How fast can a rotary engine spin?
The rotary delivers power linearly all the way to 7,000 or 8,000 RPM, depending on engine specifics, and that flat power band sets it apart from rev-happy piston engines that too often pour on the power at high RPM while feeling gutless at low RPM. Carmakers also liked the rotary for its smoothness.
How is redline determined?
The manufacturer determines the redline of the engine based on the ability to get rid of the heat, friction, and centrifugal forces on the crankshaft, and other forces on the piston and connecting rods. Remember that the piston has to start and stop at the top and bottom of each stroke, and go the other way.
What does the red line on the RPM mean?
The “redline” on a tachometer indicates that engine speeds (measured in RPM, revolutions per minute) above that value are likely to cause damage to the engine, especially if operated continuously at that speed for more than a few seconds.
What is RPM redline?
The term redline is said to come from the fact that you are reaching the red lines on a tachometer (RPM counter), hence the name. It is the maximum engine speed you can achieve that will not harm the car.
Why are RX-8 so cheap?
Poor Fuel Economy & Daily Drivability
Another reason why the RX8 is cheap to buy now is because many are put off by the poor fuel economy of the car. Rotary engines might be small in size (and produce substantial power relative to that size) but they have a tendency to be thirsty.
Does RX-8 have a turbo?
A turbocharged Mazda RX-8 provides for higher output levels and a smooth power delivery. It is ideal to place the turbo low in the chassis in order to yield low temperatures under the hood.
Why do rotary engines rev so high?
Rotary engines are also known for revving high, and that's because in eschewing pistons altogether, they don't have any reciprocating mass, just rotational mass. You also need lots of air, which is why the Honda S2000 employs variable lift on its intake valves.
How long do rotary engines last RX-8?
How long will the RX-8 engine last? There are various answers and speculations as to how long a typical RENESIS engine can last for. Just like any other engine, taking the time to care for it properly will make it last longer than usual, however, that could mean 80,000 miles or less.
What year RX-8 should I buy?
As the RX-8 didn't change much over its seven year run, we'd recommend going with a 2010 or newer model due to the improvements in the engine that greatly reduce roughness, flooding and most importantly, oil consumption. If you're on a budget and looking at an older model, try to find a low-mileage one-owner car.
