AT Power and Specialist Components are proud to launch their direct to head individual throttle body engine management system for the Cosworth YB engine. Combining the patented shaftless technology of AT Power's billet throttle bodies with the performance of SC's Typhoon engine management system into a formidable power adder package for Cosworth YB engines.

This complete kit can take a Cosworth YB engine to 170bhp, with excellent, responsive driveability and more torque throughout the rev range.

The kit package comprises the following components:

Active Power Throttle Body Set (assembled and vacuum balanced)
Throttle Linkage
Extension Tubes
Ram Pipes
Stainless Fuel Rail
O-rings for fitment
Sealing washers for air filter/airbox
Throttle Position Sensor
Billet Fuel Pressure Regulator
SC Typhoon Engine Management System
New SC Engine Wiring Loom to fit Cosworth YB & Typhoon ECU
ECU To PC USB Interface


SC Typhoon ECU for Cosworth YB uses all the standard Cosworth sensors and drives all the standard actuators. Typhoon uses advanced engine management software, along with fully sequential injection and ignition control. The Typhoon ECU is supplied pre-mapped for the standard Cosworth YB engine to match the AT Power Throttle Bodies using the standard Bosch injectors. Modified engines will require re-mapping to suit.
Combined with suitable fuel line modifications, this kit contains everything needed to convert a standard Cosworth YB engine to the AT Power individual throttle bodies and SC Typhoon engine management.
