What Is Two Step? Rev Limiters Explained

Two-step rev limiters have two separate RPMs for which a rev limit is set, depending on certain conditions. Typically the first rev limiter is used when the car is stationary, as launch control. 

The second rev limiter is the redline (or slightly past) there to ensure you don't damage the engine by over-revving. Rev limiters work by either limiting fuel, or limiting spark. You can run a lean A/F mixture, or cut fuel entirely. Likewise, you can retard spark timing, or kill the spark entirely, but this means unburnt fuel will exit the exhaust, thus leading to pops and crackles as the unburnt fuel ignites with the outside air. 

Two step is not by design an anti-lag system, but by significantly retarding the timing, it can act very similarly, and achieve the same goal, though only for launches. Once the vehicle is moving, the system will not attempt to maintain boost during shifts, as traditional anti-lag systems would.

Engine Knock Sound - Explained

What is the knocking sound coming from my engine? What is engine knock? Why is my engine making a knocking noise? Engine knock, or pinging, occurs when a separate pocket of air-fuel mixture ignites after the spark has ignited the air-fuel mixture within the combustion chamber. Engine knock can be prevented using higher octane fuels, retarding ignition timing, or by using a lower compression ratio, among other solutions.

The New Porsche 911 GT3's Engine Is A Masterpiece

The new Porsche 911 GT3 engine revs to 9,000 RPM. The 4.0L boxer six-cylinder is naturally aspirated, producing 502 horsepower and 346 lb-ft of torque. The engine is packed with clever features including individual throttle bodies, two resonance valves, rigid valve train, DLC-coated rocker arms, large-bore cylinders, and a dry sump oil system with seven pickup locations, ensuring proper oil flow under track conditions. The 4.0L has seen numerous updates since its introduction in the 2011 GT3 RS 4.0, and has been used in subsequent 911 GT3 variants since.

The 2022 GT3 has also lapped the Nurburgring in just under seven minutes! Thanks to weight reduction through material selection such as carbon fiber reinforced plastic, titanium engine components, and special glass, the curb weight is kept low. Handling is improved with a new front and rear suspension, completely redesigned from the standard 911. Grip is maximized with Michelin Cup 2 R tires, and significantly increased downforce over the previous GT3.
