PRI 2012: Turbonetics Now Offers X275, T4 Turbos

Turbonetics is introducing a full-featured turbo for drag racers competing in the popular X275 class that limits turbos to specific dimensions. 

“We offer this turbo with either an 85mm or 88mm billet compressor wheel,” says Reggie Wynn of Turobnetics. “It also comes with a 112mm turbine and ceramic ball bearings.”

The ball bearings are crucial to turbo performance. Turbonetics uses silicone-nitride ceramic ball bearings that are designed to withstand loads from 1000 up to 2,500 pounds. Conventional ball bearings assemblies may not handle more than 80 pounds. Another racer-friendly feature of the X275 turbo is a provision for a speed sensor so owners can monitor shaft speed for tuning purposes or record information during runs on a data logger.

While the X275 is based on a T6 footprint, Turbonetics is also releasing a line of T4 turbochargers to help customers experiencing back-pressure issues.

“We basically took a T4 housing and stuffed our F175 turbine wheel into it,” says Wynn. “So, now you’re moving up from a 68mm turbine wheel up to a 75mm.”

The T4 family should help larger displacement engines, including LSX applications, if they’re experiencing back-pressure problems. The T4 offers all other Turbonetics features like ceramic ball bearings, full balancing on the component and assembly levels and a 1-year warranty.

On display in the turbonetics booth was a 1976 Porsche 911 that had been upgraded with a twin-turbo engine from a 997 Porsche. It was built by Bisimoto Engineering.
