Project CARS 3

n Oxygen is life and it’s also key to engine performance—the cleaner the air that gets to your combustion chamber, the more power you’ll get, which is where Air Intakes come in to your upgrade equation. A camshaft, meanwhile, works by opening and closing the intake valves—the better the timing with respect to the cylinder position, the better the engine performs. Air Intake and Camshaft upgrades are largely about getting power gains in the upper portion of the rev range and improving the engine’s breathing for higher performance close to the redline. Engine Block Upgrades The engine block is what holds pretty-much all the business bits of your engine—pistons, cylinders, and so on. Back in the day, these were cast iron, but that’s been replaced by aluminium to allow for the most efficient cooling of the engine. These types of upgrades cover a wide category of parts in your engine—heads, manifolds, and pistons, for instance—which will result in a general increase in torque across the engine’s RPM range. So if you’re lacking low-end grunt out of turns, here’s a good solution.
