The Harley Davidson's standard power output of 112bhp is adequate for cruising around but when pushed there just isn't enough torque for those high speed moments. The TTS solution comes in the form of a C15-60 Rotrex supercharger which boosts power output by a minimum of 40%* This is with a restricted boost pressure of just 0.4 bar (6psi).

 

This is the limit of the OE fuel pump. With bigger fuel pump and injectors 200 whp is feasible (engine built to suit). Driveability is fantastic with instant throttle response from idle to redline. All parts are CNC machined in TTS’s workshops to maintain the highest quality available. 

 

The conversion can be supplied in bare aluminium, polished or black Zylan coating.

 

In order to fit this conversion a Dynojet Power Commander or similar is required to meter fuelling and ignition.

 

The conversion comes with comprehensive fitting instructions.This conversion is supplied in bare aluminium, or can be supplied polished or black Xylan coated for an additional cost.
