Most of our stage kits work on either the 996 Turbo or X50 models. The Turbo S comes with the larger K24 turbos and GT2 intercoolers. Again for the newbs, most 996TT’s come with the K16′s which are smaller producing less boost stock and power then the K24 turbos. The same mods can be applied to the X50 or Turbo S, but the gains are not as great as you see on the K16 car. Usually, this stage 2 will net about 110 awhp on our Mustang Dyno running 91 octane. A X50 is already running 0.8bar of boost about. However you are flowing more air through the larger turbo so 0.8bar on K24s still makes more then 1.0bar on K16′s… On our Mustang AWD Dyno, a typical X50 car makes about 380awhp.
The first step is our VR Tuned ECU Flash. This is done via the OBDII port with a supplied cable and easy to use instructions. With the flash, we include a 1 step colder spark plug. Why? The 1 step colder works well on increased boost cars without causing misfire that usually happens on old stock heat range plugs. After the plug upgrade comes the exhaust system. This package includes the Agency Power titanium exhaust which has an incredible sound and is very lightweight. Featuring integrated quad tips, the system helps the mid to top end power band and gives you a mellow tone when cruising. With the exhaust, more air flow is needed. For simplicity and pricing restraints, we will add the very effective and affordable K&N drop in filter. The turbo car must breathe better. While the stock airbox is out, we will also add in the necessary with all 996TT upgraded Diverter Valves. The factor Bosch valves have a diaphram system that leaks boost on the upper end of the RPM robbing you of power. Our Agency Power Valves, available in black or polished, use a piston and spring design. To make the install easier, we always include an Agency Power Silicone F-Hose. With the mods all installed, this car gained about 70awhp and 70ft/lbs of torque over our baseline. Check out the video and dyno.
