How to Increase Power for a 1.5L Engine?
2 Answers
The principle of lowering the intake air temperature is that colder air has a higher density, allowing more air and fuel mixture to be drawn in the same volume, resulting in more complete fuel combustion and increased energy output. This method can boost power by 5-7 horsepower, with low modification costs and easy implementation. Replacing a set of lighter wheels paired with smaller-sized tires can reduce weight and enhance vehicle power. However, changing to different-sized tires may lead to inaccurate speed readings and abnormal tire wear. Professional adjustments are required; otherwise, the modification results may deviate from expectations.
I've driven many small-displacement cars, and when it comes to boosting the power of a 1.5L engine, I believe starting with the simplest methods is the most reliable approach. First, you can upgrade to a high-performance air filter—it's low-cost and easy to install, and the improved airflow will make acceleration smoother. Next, consider an ECU remap; many tuning shops can help adjust fuel injection and ignition timing, potentially increasing power by around 10%. The exhaust system is also worth modifying—installing a larger-diameter tailpipe allows exhaust gases to exit faster, making the engine more responsive. Don’t forget spark plugs; high-performance ones provide stronger ignition, giving you more punch off the line. Regular maintenance is key too, like periodically cleaning the throttle body to reduce carbon buildup and dust, ensuring the engine breathes freely and performs better. Combined, these modifications can deliver noticeable results. I recommend trying them step by step rather than rushing into all changes at once.
