Stealth 64 VVT - LBZ/LLY/LMM 650rwhp

Easy Install, Snappy Response, EGT control, and Turbine braking

The VVT Stealth 64 Turbo takes a stock appearing LBZ/LLY/LMM turbocharger and overhauls it to meet the demands of the Duramaxtuner team.

The stock LBZ/LLY/LMM turbocharger runs out of air at about 530rwhp. It has trouble controlling EGTs on extended pulls past 400HP. The Stealth 64 VVT extends the useful power curve of the engine out another 120HP to 650rwhp. Furthermore, the Stealth 64 VVT is much better at controlling exhaust gas temperatures under sustained load when towing up long grades at high power. This is accomplished through the use of a specially designed billet compressor wheel which is matched to a higher flowing turbine assembly. This match represents the best balance between quick spool-up response for driveability and overall compressor flow for peak power for truck owners looking to make 650rwhp.
