If you've been shopping HPT Turbochargers recently, you may have noticed a new name in our lineup: the F3C (Compact) series.
If it looks familiar, that's because it is.
The F3C turbochargers were previously known as our F2.5 Series, but after listening to customer feedback, we decided to simplify the naming convention. The "F2.5" designation often left people wondering exactly where it fit between our F2 and F3 turbocharger families. The new name tells the story much more clearly.
F3C stands for F3 Compact.
It delivers the horsepower potential and durability of our F3 platform while maintaining the compact compressor package of our F2 series.
What Makes the F3C Different?
The F3C combines components from two of our most popular turbocharger families:
- F2 Compressor Cover for a more compact overall package
- F3 Stainless Steel Turbine Housing for increased airflow and horsepower capability
Think of it as getting the best of both worlds.
The smaller compressor cover helps when space is limited, while the larger F3 turbine section allows the turbocharger to support significantly more horsepower than a traditional F2 turbocharger.
Why Choose an F3C Instead of an F2?
Our F2 turbochargers have earned a reputation for excellent spool-up and performance, making them a favorite for many street and race applications.
However, if your combination is pushing for more power, the F3C gives you additional headroom without dramatically increasing the overall size of the turbocharger.
Benefits of the F3C include:
- Higher horsepower capability than comparable F2 models
- Compact compressor housing for improved engine bay clearance
- Stainless steel F3 turbine housing
- HPT Quick Spool Technology™ for excellent transient response
- Ceramic dual ball bearing system
- Lightweight rotating assembly for fast acceleration
The result is a turbocharger that still responds quickly while supporting serious horsepower goals.
Available F3C Models
Currently, the HPT F3C lineup includes two popular sizes.
F3C 7175
