Frequently Asked Questions
Will my engine make the advertised HP?
The 1,450 HP figure is the Turbo’s potential power-support capability, not guaranteed engine output or a measured wheel-power result. The engine specification, fuel system, supporting modifications and tune determine the actual result.
Does speed sensor provision mean a sensor is included?
No. “Provision” describes a mounting provision for a compatible sensor. It is not a sensor-inclusion claim; see What’s in the Box? for the supplied parts.
Is the compressor outlet V-band fitting included?
The turbine outlet ring and clamp are supplied. The compressor outlet V-band fitting is not included.
