The Turbonetics TN 700 Turbocharger - 11518-BB: At the end of the day all you care about is power, right? That's where the TN Series of turbochargers comes in. "No non-sense, just power" is this lineups motto. Turbonetics has put together a no frills selection of units based purely on horsepower numbers to make it easy for you to select the unit you need. Offered with our clean casted compressor housing and primarily in journal bearing configurations. Higher horsepower models come only with Turbonetics ceramic ball bearing option for strength and durability purposes. Due to the tremendous thrust loads the high horsepower units can achieve and the large size of the compressor and turbine wheel combinations, Turbonetics only builds 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.
