Stroked Ford engines have been popular for a long time, and some of you have first-hand experience in building big-cube engines using 302s and 351Ws as starting points. But not everyone is an expert builder, and for those who might be first-timers or a little apprehensive, Scat [(310) 370-5501; www.scatcrankshafts.com] now offers complete cast, forged, or billet rotating-assembly packages that include not only the usual crankshaft and rods, but also pistons of the customer's choice (JE, Ross, SRP, Mahle, and so on). Each rotating assembly is precision balanced and comes as a collection of ready-to-go, wash-and-install parts that takes all the guesswork out of building a stout stroker for your 'Stang.
Former NMRA Pro 5.0 pilot Brandon Switzer's company, Speedtech Innovative Nitrous Solutions [(205) 758-7100; www.speedtechnitrous.com], showed off its 75-150hp wet nitrous system for S197s. This Speedtech kit features the company's Liquid Force nozzle that increases/decreases fuel flow accordingly when nitrous flow is increased or decreased. Brandon says the unique nozzle promotes a flat fuel curve, which is a plus for maintaining proper nitrous-to-fuel balance throughout the length of a run.
During our King of the Street competition, we had the opportunity to drive an '05 Mustang GT with a TCI stall converter. We barely noticed it was there, thanks to its smooth operation, and the car was a legit 600hp, 10-second ride. TCI's [(888) 776-9824; www.tciauto.com] '05-and-up Mustang GT converter is a 10-inch diameter, direct bolt-in 5R55 stall converter. Available in Super StreetFighter (3,500-stall) and Competition (3,800-stall) versions, the increased stall speeds allow the engine to get into its powerband at launch. Both versions are full lock-up converters and feature hand-built steel stators, heavy-duty clutches, furnace-brazed turbine fins, a modified impellor fin angle, TCI-exclusive HDT coating, and INA thrust bearings for lowered internal friction.
Trick Flow has more news [(330) 630-1555; www.trickflow.com] with its Two-Valve modular intake. These things are begininng to show up on the aftermarket. Trick Flow's 4.6 Track Heat intake is made from A319 aluminum alloy and designed for '99-'04 Two-Valve PI heads. Owners of '96-'98 Two-Valves will have to add either PI heads or the appropriate spacers to adapt Trick Flow's intake to the heads. This intake is ready for serious power since it comes with a 75mm throttle body inlet, a symmetrical high-velocity intake port design, and a broad rpm range with stock or modified heads. The intake is the same height as the stock plastic intake, so hood clearance shouldn't be an issue, either.
If you have taken your S197 Mustang to the next performance level and are in need of more traction, TRZ Motorsports' [(407) 933-7385; www.trzmotorsports.com] rear suspension package might be what you need. The package features an antiroll bar with an integral sway bar to replace the factory Panhard rod, tubular lower control arms, and a double-adjustable third link (upper control arm). TRZ designed this suspension system to help your '05-and-up Mustang launch straight, with more effective weight transfer.
Vortech Engineering [(805) 247-0226; www.vortechsuperchargers.com] has made a huge comeback into racing with its new V-28-130A Race Trim supercharger. With 32 pounds of boost, we can already see racers lining up to get their hands on it. The biggest deal on this supercharger is its sprag drive (overrun clutch) option, which reduces belt and supercharger stress during on/off throttle situations. A sprag setup allows the supercharger to freewheel during deceleration and throttle modulation instances. That will come in handy in racing classes such as Super Street Outlaw and drag radial-type racing. It's capable of supporting 1,800 hp or more, so the weak need not apply.
Roughly 1 percent of Mustang owners need Wilson Manifolds' [(954) 771-6216; www.wilsonmanifolds.com] new 105mm throttle body elbow, but 100 percent of us want one. This CNC-machined billet elbow is computer-optimized for maximum power and optimum airflow distribution. The elbow is able to support upward of 2,000 hp and features a 4500 series carburetor flange design.
