Speeding Up the STi Progress
The Castrol Edge Auto Makeover Subaru is closing in on its deadline quickly. The car has left the coast with incomplete sound and multimedia and arrived in JHB where the final phases will begin. Luckily P&P Car Sound Specialists are a national outfit and can complete the small glitches in order to complete the gadgetry in the STi.
The vehicle was taken to Subaru Specialists, NXGen, who are located in Randburg. The car was lifted onto their state-of-the-art four-wheel drive Dynapack Dyno, so a comparison in power could be assessed after the changes were done. Sensors are placed in the STi motor to gauge feedback so the advanced system can calculate the vehicles performance figures from the test.
A Bosal performance exhaust, ECUTEK engine management software and a DEFI Gauge system were installed. The larger diameter exhaust system fitted runs from the turbo to the tailpiece and allows the engine to breath better. Meanwhile, the ECUTEK engine management software overrides and controls every aspect of the vehicles standard ECU, which was then expertly tuned and calibrated by the guys at NXGen to optimise timing and fuel flow. This in turn means more power, torque and better engine response. 
Having completed the necessary modifications, Craig was able to increase the power output of the Castrol Edge Auto Makeover Subaru from 179kW to a staggering 197kW of power - just short of a 20kW increase.
