HPA's Full Throttle EXTREME turbo systems feature Borg Warner's EFR 8374 turbo which delivers instant throttle response and supports multiple boost settings. Under 20 psi this system delivers an exciting 500+ ft-lbs torque and 500+ hp. By upgrading a variety of support parts, ferocious power figures in the 600 range are easily achieved.
The lengthy list of components that go into each and every built-to-order turbo system includes several proprietary developments that set HPA turbo kits apart from the rest:
Velocity Tuned Exhaust manifolds are cast from the highest quality materials. HPA manifolds retain the critical orientation and placement of the engine's oxygen sensors to ensure correct fuel calibrations and DSG-> engine communications. Their exhaust manifolds will deliver instant throttle response while insulating and dispersing generated heat. There are no design short cuts with this Manifold!
Integrated liquid cooled cast intake manifold is an all in one design specific solution that takes the workload off the turbo; lowering EGT's and affording more ignition in the software maps yielding best in market throttle response and performance. In daily stop and go, no other after cooling solution is as effective as the air to water in generating a cool and steady intake temp.
