Increasing Horsepower on Subaru WRX
If you’re looking to increase the horsepower of your Subaru WRX, there are several modifications you can consider. Here are some steps you can take based on the information from the search results:
1. Intake and Exhaust Upgrades: Upgrading the intake and exhaust systems can improve airflow and increase horsepower. According to the search results, installing a K&N Typhoon intake and a Magnaflow exhaust on a Subaru WRX resulted in an increase of 11 horsepower over stock. Another source mentions that a stainless-steel exhaust can increase torque by 10 pound-feet. These modifications can be relatively simple bolt-on upgrades.
2. Engine Remapping: Engine remapping, also known as tuning, can optimize the performance of your Subaru WRX. This involves adjusting the engine’s computer settings to improve power output. One source suggests visiting an engine remapping specialist to get more horsepower from the engine. It’s important to note that engine remapping may require additional modifications to support the increased power.
3. Performance Exhaust System: Upgrading to a performance exhaust system, such as the STI Performance exhaust, can improve exhaust flow and overall efficiency. While the exact power increase is not mentioned in the search results, it is stated that the performance exhaust system allows exhaust gases to flow more freely, which can improve performance.
4. Bolt-On Modifications: There are various bolt-on modifications available for the Subaru WRX that can increase horsepower. These modifications include items like intercoolers, turbochargers, and fuel system upgrades. However, it’s important to ensure that these modifications are compatible with your specific model and that the necessary supporting modifications, such as tuning, are also performed.
It’s worth noting that modifying your vehicle may have implications for its warranty and could potentially affect its reliability and longevity. It’s always recommended to consult with professionals or experienced enthusiasts who have expertise in Subaru WRX modifications before making any changes to your vehicle.
Remember, modifying your vehicle should be done responsibly and within legal limits, considering factors such as local regulations and safety.
