In this article, we will explore how to choose the right turbo size to achieve over 400 horsepower, focusing on the Precision Turbo sizing guide.
Understanding Turbochargers
A turbocharger is an essential component that forces more air into the engine, allowing for more fuel to be burned and thus increasing power output. Selecting the right turbocharger is crucial for maximizing performance without sacrificing reliability. Here are some factors to consider when choosing a turbo for your BMW 335i:
- Engine displacement
- Desired horsepower
- Boost levels
- Fuel type
- Driving style
