The Mishimoto 22-inch WRX top mount intercooler is a popular upgrade among Subaru enthusiasts looking to enhance their vehicle’s performance. This article delves into performance testing of this intercooler, showcasing the power gains achieved before and after installation.
Understanding Intercoolers
An intercooler is a crucial component in turbocharged vehicles, serving to cool the air entering the engine. Cooler air is denser, allowing for more oxygen to enter the combustion chamber, which can lead to improved power output and efficiency.
The Mishimoto 22-Inch WRX Top Mount Intercooler
The Mishimoto intercooler is designed specifically for the Subaru WRX, featuring a larger core compared to the stock unit. This upgrade aims to reduce intake temperatures and increase performance. Key features include:
- 22-inch core for improved airflow
- High-quality aluminum construction
- Direct fitment for easy installation
Testing Methodology
To evaluate the performance gains from the Mishimoto intercooler, we conducted a series of tests. The testing methodology included:
- Baseline dyno runs with the stock intercooler
- Installation of the Mishimoto intercooler
- Follow-up dyno runs to measure power gains
Baseline Performance Data
Before installing the Mishimoto intercooler, we recorded baseline performance data on a stock WRX. The key metrics included:
- Horsepower: 250 hp
