On the Dyno

You have to love factory-super charged Mustangs. They are built for bolt-on improvements. Terminators really pioneered this movement, and you can see that they still uphold their reputation with a supercharger upgrade. "The TVS supercharged Terminators continue with excellent torque production seen on GT500s and 5.0s, and the large inlet on the Cobra TVS gives it excellent power potential," Justin explained. "The 2.3 is a capable blower, we have already seen it produce over 800 rwhp. The Cobra TVS' strength is in the inlet design, which allows for future upgrades." That potential is obvious on Jeff's car. You can see how the stock supercharger peaks in the midrange and tapers off at the top of the tach. The VMP TVS, on the other hand, keeps thundering out the back door, and delivers gains of 173.22 hp and 147.52 lb-ft of torque. Of course those gains were aided by the support hardware, but even so, such a stout gain over the entire powerband is stellar.

To keep that new boost cooler, Justin upgraded Jeff's car to one of Afco's Pro Series dual-pass heat exchangers with dual fans (PN 80275PRO; $640). We've had great luck with the GT500 version of this heat exchanger on PVT. Lowering and stabilizing intercooler temps is always a good idea.
