How to Increase Power in a Naturally Aspirated Car?
2 Answers
You need to replace high-flow fuel injectors, reprogram the ECU, and install high-angle camshafts. Naturally aspirated cars can also directly install a supercharger or turbocharger to increase power. Using a forced induction system is the most direct and effective method to boost power. Turbocharging technology can increase engine air intake without enlarging engine displacement.
From a modification perspective, improving the power of naturally aspirated cars. The key lies in optimizing engine breathing, such as replacing a high-performance air filter, which can increase air intake, allowing the engine to inhale more air for combustion. The exhaust system is also important; modifying the mid or rear section of the exhaust can reduce backpressure, enhance output power, and make the exhaust note more thrilling. ECU tuning should not be overlooked; rewriting the program to adjust ignition timing and fuel injection can unlock hidden power, achieving a 5-10 horsepower increase even without a turbo. Weight reduction is also effective—switching to lightweight wheels or removing excess weight can make acceleration more responsive. Lastly, regular maintenance, such as cleaning the throttle body and replacing spark plugs, ensures the engine is well-lubricated and runs smoothly. It's recommended to proceed step by step, starting with a professional evaluation to avoid a one-time major overhaul that could lead to increased fuel consumption or engine failure.
