Power Adders: Performance Products For Your Truck & SUV

Gimme Some Space
According to Trans-Dapt, in recent dyno and real-world testing of a 2004 GMC 4.8-liter truck, the company's Torque-Curve Technology throttle body spacer showed an increase of 54.3 pound-feet of torque over stock. The spacer works on 1999-2007 Chevy/GMC pickups and SUVs with 4.8-, 5.3-, 6.0-, and 8.1-liter engines to improve passing power and hauling performance. Trans-Dapt Performance Products; 562/921-0404.

Way Cool Setup
Roush's intercooled RoushCharger for 2004-2006 Ford F-150s with the 5.4-liter, three-valve modular engine provides gains of 145 horsepower and 135 pound-feet of torque at the flywheel. Main components include a Roush M112 Roots-style supercharger, an intake manifold, an air-to-water intercooler system, high-flow fuel injectors, and an induction system. The key to maximizing performance is the upgraded computer calibration that Roush will install on your truck's PCM. Roush Performance; 800/597-6874.

Think Again
Gale Banks' OttoMind Programmer is now available for late-model V 6 and V 8 Ford F-150s. The all-in-one tuner/scan tool optimizes spark timing and delivers quick merging and passing responsiveness, while improving top-end power and increasing horsepower and torque at the shift points. It displays several critical engine functions and can scan and clear vehicle trouble codes. It's upgradeable, too, so you don't have to worry about it getting out of date. Gale Banks Engineering; 866/775-3535.

Make That H3 Hum
Turbonetics' bolt-on turbo system for the 2005-2007 Hummer H3 takes the truck's inline-five-cylinder from the stock 225 horsepower to 350 crankshaft horsepower at 8 psi of boost (on 94-octane fuel). It provides improved throttle response and acceleration, along with serious top-end power. The system includes a durable ceramic ball-bearing turbocharger with quick spool-up, intercooler, wastegate, bypass valve, and an ECU that reflashes your truck's engine management computer. Turbonetics; 805/581-0333.

Ram It In
ATI's HO Intercooled ProCharger for the Dodge Hemi Ram produces 45 to 50 percent more power on a stock engine--on pump gas--with 6 psi of boost. The intercooled system offers a cool intake charge, which nets top-level power gains and superior engine longevity. The complete system comes with ATI's self-contained centrifugal supercharger, a three-core air-to-air intercooler system, and supplemental injectors. ATI ProCharger; 913/338-2886.

Sexier Sixes
BamaChips custom tunes the SCT X-Calibrator to deliver an additional 17 horsepower and 15 pound-feet of torque to the rear wheels on 2005-2007 Ford Rangers and Explorers with the 4.0 liter V 6. For this custom tuning, BamaChips raises or removes rev and speed limiters, optimizes fuel curves, spark curves, and air/fuel ratios, and improves shift quality on automatic-equipped trucks. The company offers four tunes based on the grade of fuel available in your area: 87, 89 Performance, 91/93 Performance, and 91/93 Torque. The Torque tune focuses on the 1500-to-3500-rpm range and the Performance tunes targets top-end horsepower and throttle response from 3000 rpm up. BamaChips Custom Tuning; 205/302-0231.

Forced Air for Fords
Ford Racing's supercharger kit for 2005-2006 F 150s with the 5.4 liter three-valve V 8 is good for an increase of about 160 horsepower and 160 pound-feet of torque at the rear wheels. The kit, designed by Ford Racing and Whipple engineers, uses a Whipple twin-screw-style supercharger. It comes with everything you need, including a 95mm mass air meter--but the kit does void the factory powertrain warranty. Ford Racing Performance Parts; 800/367-3788.
