At the end of the day all you care about is power, right? How much can I make without breaking the bank? That's where the TN Series of turbochargers comes in. "No nonsense, just power" is this line up's motto. Turbonetics has put together a no-frills selection of units based purely on horsepower numbers to make it easy to select the unit you need. Offered with clean casted compressor housing and primarily in-journal bearing configurations, some specific models come only with Turbonetics ceramic ball bearing option for strength and durability. Due to the tremendous thrust loads high-horsepower units can achieve and the large size of the compressor and turbine wheel combinations, we only build these turbos to live. And that means using the race-proven Ceramic Ball Bearing for fast spool-up and the strength to survive big boost.
Do you have a tight fit that you still need to make big power with or a twin turbo, lower boost application that is normally tough to find efficient units for? Look to the "Hi-Fi" models to provide large volume in smaller sized compressor and turbine housing combos. You still get great flow from a smaller dimension package with a tight compressor A/R for fast response.
