The Next Step Up
Next Gen 6670 is Precision’s largest single-turbo Next Gen offering. 66 mm compressor paired with a 70 mm turbine wheel, 1100 HP rating. This is the turbo that shows up on Pro Mod cars, big-block drag cars, and dyno-record builds that treat 50+ psi of boost as a starting point. When the 6466 runs out of top-end, this is the answer.
Competition Engineered Aerodynamics
Next Gen 66 mm CEA compressor. Precision’s flagship compressor wheel — the design choices made here trickle down to the smaller Next Gen frames. Pressure ratio ceiling is the highest in the single-turbo CEA lineup, and the efficiency map is tuned specifically for the 50+ psi operating points that big-block drag engines demand.
Dual Ceramic Center Section
Next Gen dual ceramic ball bearing cartridge, Next Gen 6670 spec. Rated for the shaft speeds a 66 mm compressor pulls at 50+ psi without drifting. Tight clearances, high-temp tolerance seals, and assembly standards that have produced multiple NHRA drag records.
