If you’re looking for tons of reliable, street-legal power for your new Mustang, Edelbrock’s E-Force Supercharger may be the answer.

Computer-controlled late-model cars get more complicated every year, and at the same time the regulations limiting the mods you can do on them get stricter. The situation has resulted in fewer performance choices, most of them also less savory, too. If you’re a late-model Mustang fan like me, you’re staring at a pretty bleak buffet: mods that don’t work, mods that render your car illegal, or legal mods that do work, but are really expensive. There are even really expensive mods that don’t work, and are illegal to boot.

So when I saw Edelbrock’s new blower kit announcement in my “in box” today, I got excited. And while I haven’t tried one to see if it works as advertised, the specs, advertised performance, and retail price put it in the sweet part of the performance value curve—an area that Edelbrock excels in.

The new kit is specifically for 2005-2009 Mustang GTs with the 4.6-liter three-valve engine. The centerpiece is an Eaton Twin Vortices Series (TVS) Gen VI rotor assembly that’s teamed with a 110 square-inch air-to-water intercooler. Edelbrock quotes their 50-state street-legal kit (part No. 1580) at 466 hp and 439 lb-ft of torque with just 5 psi of boost. Edelbrock says everything needed for a complete, turn-key installation is right in the box, including an 85mm throttle body, fuel injectors, intercooler, spark plugs, coil covers, and a handheld flash tuner. (Finally, a blower kit manufacturer who doesn’t make you send off your computer!)

One part I like is the price: $5,795.87, retail. Yes, there are less expensive kits out there, but they aren’t street-legal, and your computer tune will be at the mercy of the post office. I also like the Eaton TVS design of the Edelbrock kit. Compared to centrifugal kits, boost is immediate. There’s another reason I like it too: Centrifugal kits—especially intercooled ones—rely on mass air meters that are measuring airflow as far as four or five linear feet from the combustion process. That means processor lag time and driveability issues. The TVS kit is compact and mounts on the engine, which dramatically improves the fuel calibration. Heck, the MAF meter is right there where all the action is! That’s one reason you see Eaton blowers used on factory applications like the Shelby GT500 and the Corvette ZR-1. They flat-out work, and they’re reliable enough for a factory warranty. Speaking of which, Edelbrock offers an optional 3-year, 36,000-mile warranty. (Other companies do offer warranties on their ’05-09 Mustang kits, but you kind of wonder how that’s possible, since they aren’t street legal. Go figure.)
