Four bolts along the bottom, and one at the top secure the unit. |  The intercooler fluid reservoir...  The intercooler fluid reservoir and water pump are also delivered as a subassembly, and is easily installed to a bracket fitted to the idler bracket/cross brace. Coolant lines are now connected between the supercharger intercooler, the fluid reservoir and water pump, the heat exchanger, and back to the intercooler. |  After Travis finishes a computer...  After Travis finishes a computer tune using SCT software, we're ready to rock! Not only does the finished product lay down impressive power, but it turns the industrial-looking 4.6 Two-Valve into an undeniably muscular piece from a visual perspective. |
Tork Tech's '99 GT demonstrator...
Tork Tech's '99 GT demonstrator laid down about what we'd expect of an 88,000-mile original with fresh plugs. We saw peaks of 237 hp and 261 lb-ft of torque as measured on Fast Specialties' Mustang MD1750SE dyno.
The final tune for an otherwise bone-stock GT was still undergoing massaging during our visit. Right after installation, tech Travis Hall had the car up and running a conservative program via SCT software, with 374 hp and 360 lb-ft at just more than 9 pounds of boost. The more aggressive tune shown here pumped out peaks of 406 hp and 399 lb-ft, but is frankly a bit more than Tork Tech wants as standard issue. Expecting many of these kits to be installed on stock short-blocks, the cookie-cutter tune will have a better margin of safety in deference to the 4.6's weak bottom end, more along the lines of 380-390 hp and similar torque. Nevertheless, the numbers here illustrate what can be achieved through your favorite local tuner with standard pulleys and pump gas. However, a beefy short-block is recommended.
We took a 20-minute testdrive on the 374-horse tune and found it to be as docile and well behaved as any stocker--until the throttle met the wood. At that point, the similarities end and '03-'04 Cobra-like acceleration takes over, along with enough blower whine to remind you of the reason for the extra thrust.

At press time, the following prices applied to Tork Tech's '99-'04 Two-Valve application. Note, there is a non-intercooled kit available for $600 less than the intercooled setup we previewed, but the intercooled arrangement is clearly money well spent. Also note that both kits can be had in "tuner" form, meaning there is no computer tuning, no mass air, no injectors, and no fuel pump. Tork Tech recognizes that some customers want to work with their own local shop for tuning, and may have previously purchased suitable high-performance gear which need not be purchased again. Tuner kits are intended for this group of enthusiasts.
