Building a 600 hp air cooled 911 turbo is less about one “big turbo” moment and more about planning a balanced system: air, fuel, spark, cooling, drivetrain, and brakes that…

Planning a 400 hp air cooled 911 build is less about chasing a dyno number and more about engineering a streetable system: turbo sizing, intercooling, fuel delivery, ignition control, heat…

On an air-cooled 911 Turbo, power isn’t just “more boost.” It’s the relationship between boost, exhaust energy, turbine efficiency, and one often-misunderstood constraint: exhaust backpressure turbo 911. Backpressure is the…

Choosing the right 911 turbo header manifold is one of the highest-leverage decisions you can make on an air-cooled 911 turbo build—whether you’re adding boost to an SC/Carrera 3.2/964/993-based engine,…
