Thankfully a code-level reference to High Power Mode in the macOS Monterey beta says the feature “will optimize performance to better support resource-intensive tasks.” Additionally, the new model could also result in louder fan noise. After receiving the MacBook Pro, we would get a clearer picture of how the High Power Mode works. The new MacBook Pros are already “ Preparing to Ship,” and customers should start receiving their laptops early next week. It is not clear if the mode is triggered automatically when the system detects resource-hogging tasks. Apple’s support document reveals other details and says High Power Mode will offer “extreme performance.” This could be useful in tasks like 8K ProRes video grading.Īpple has not precisely revealed how the High Power Mode would function. All one needs to do is head over to System Preferences and toggle on the mode.

It looks like the new High Power Mode will work similarly to Intel’s Turbo Boost technology.Īpple’s document mentions how users can enable High Power Mode on a 16-inch MacBook Pro with M1 Max Chip. Apple has now confirmed the High Power Mode on MacBook Pro to MacRumors.

High Power Mode intends to deliver maximum performance during intensive tasks that last for a prolonged period. Because exhaust flow isn’t consistent across all RPM and engine loads the boost control solenoid has to do plenty of work in order to manipulate the wastegate and achieve the target boost pressure.A recent report claimed new MacBook Pro with M1 Max Chip offers a new High Power Mode. Let’s say when we’re at 85% Ethanol and 6000RPM we want 20 PSI of boost pressure – the ECU will pulse the boost control solenoid directing the pressure between the wastegate and out to atmosphere in a delicate balancing act to achieve our target boost into the engine. In the ECU we can set our Boost Target against numerous parameters like Engine RPM and Ethanol Content. The more pressure we bleed off, the more exhaust gasses the wastegate will direct through the turbine wheel resulting in more boost pressure.

We use this solenoind to manipulate the amount of boost pressure the wastegate sees. This sensor’s mounted after the throttle body but before the intake valves and measures the pressure in the intake manifold. In order for the ECU to control the boost pressure it needs to measure the boost pressure – for that we use a Manifold Pressure Sensor. There are endless combinations of boost control strategies you can employ to make the most effective use of the boost generated by your turbocharger. With electronic boost control we can have different boost pressures at different Engine RPM or depending on the Ethanol content of the fuel, or via a simple boost switch on the dash. When we have control over the speed of the compressor we effectively have control over the boost pressure. It’s also important to regulate the exhaust side to control the intake side. The turbocharger assembly spins at over 100,000 RPM and it’s important to regulate the exhaust gasses to make sure it doesn’t over-spin resulting in a catastrophic failure. It seems odd to waste all this energy but there are good reasons for that. The wastegate uses a boost referenced, spring-loaded diaphragm in order to determine just how much exhaust flow should be directed around the exhaust turbine wheel and how much should go through it. This is achieved by bypassing exhaust gasses around the exhaust turbine wheel with a component known as a Wastegate.Īs the name suggests a wastegate “wastes” engine exhaust gasses by feeding them directly into the exhaust system and around the exhaust turbine wheel. You can’t just put unlimited boost into an engine, you need to regulate the speed of the exhaust turbine wheel and in turn regulate the speed of the compressor turbine wheel.

The more compressed the intake air is – the more oxygen-dense or heavy it is, therefore the more oxygen you can get into an engine – the more power it’s going to make.

Why does boost pressure make a difference to engine power? The Compressor wheel (32) pulls fresh air through the air filter (46) and jams it into the engine (42), resulting in what we know as Boost Pressure. The faster you spin the exhaust wheel the faster the compressor wheel will spin. A turbocharger uses engine exhaust gases to spin up a turbine wheel (30), which is mounted on a common shaft (36) with a compressor wheel (32). In order to understand how boost control works we first need to understand how a turbocharger works.
