Our Own Hellcat Setup:

At AusParts International, we don’t just sell you parts, we guarantee you a setup works. That’s why we built our own Hellcat-supercharged, LS-swapped Nissan 300ZX drift car to prove it.

Our car was built for R&D and while we may have kept it somewhat conservative, our hellcat setup still produces 700 wheel horsepower (520 kW) at just 10 psi of boost, with 550 lb-ft (750 Nm) of torque delivered across the whole rev range from just 2,500 rpm.

This simple, budget-friendly combination reliably produces bulk horsepower and torque with plenty of room for more power. The Hellcat-LS setup walks the fine line of being super powerful without being hard to drive. A big part of that is due to our electronic bypass valve controllers providing smooth linear power making for an easy, consistent driving experience. If you want cheap bulk horsepower and an unmistakable sound, a Hellcat blower is the way to go.
