On The Dyno
After installing Turbonetics' CARB-legal, S197 turbocharger system on an '06 Mustang GT (stock engine, five-speed transmission), we definitely were anxious to see exactly what type of "clean" rear-wheel power and torque the huffer makes. For smog purposes and to provide general safety margins against detonation when California's 91-octane fuel (minimum octane permitted for the turbo system) is used, the company's tuning is a lot more conservative than non-smog-legal and custom calibrations we've worked with for power adders. However, although custom dyno tunes tend to be slightly leaner on the fuel side and have more timing advance, the plug-and-play PCM change that Turbonetics created is on the money overall, as both horsepower and especially torque levels show more-than-considerable gains with the bolt-on system.
The '05-'09 S197s, many of which are which are now beyond their warranty periods, have become attractive candidates for modification. Moreover, California performance enthusiasts have shied away from adding turbo systems on their Ponies for fear of incurring the wrath of CARB. Turbonetics has put an end to the apprehension, as this turbo system gives stock 'Stangs the ability to run with the big dogs and pass state emissions inspections with flying colors.
