2014 Callaway Chevrolet Silverado engineBarely a month after we first told you about Callaway's plans for the new Chevrolet Silverado and GMC Sierra, the Connecticut-based tuning shop has shown its first completed model. Using a Silverado, Callaway has fitted an Eaton TVS supercharger and developed a new calibration for GM's powertrain management system.

Improvements aside, we still haven't been told just how much more engine power is is available. Callaway says that information "will be released very soon." Initial targets for the 5.3-liter V8 saw a bump to 450 horsepower, up from 355 hp. If you just can't wait to snap up one of the supercharged trucks, authorized Callaway dealers are accepting orders on the Silverado and Sierra Crew Cabs with the 5.3-liter, supercharged V8 right now, and will expand ordering to the Extended Cab and Standard Cab models soon. Packages start at $17,395.

While GM's smaller V8 is about ready to go, Callaway isn't ignoring the bigger powertrains. It's taking the know-how from the 5.3-liter project, particularly with the engine management software, and is applying it to GM's upcoming 6.2-liter, V8-powered vehicles. By the end of the year, the Callaway Sierra and Silverado will be available with the 6.2, for those that need even more thrust. And of course, we can expect the highly anticipated Callaway Corvette to arrive by the end of the year, as well. Scroll down for the official press release from Callaway.

CALLAWAY ANNOUNCES FIRST SUPERCHARGED 2014 SILVERADO

Another first for Callaway, the specialist manufacturer has just developed a new version of the service-proven Eaton TVS supercharger for the 2014 Silverado/Sierra 5.3L. Shown in the attached photos with data collection instrumentation still attached, the Callaway system includes a new supercharger manifold and other hardware required for the new Chevrolet L83 "Eco-Tec" engine. Callaway engineers also developed calibration for the new-for-'14 GM electronic powertrain management system. Significantly different for 2014, the new electronics control Direct Injection, continuously Variable Valve Timing, Active Fuel Management and other engine functions.

While the new powertrain management system provided new challenges for Callaway's development staff, its additional control authority also provided improved refinement and integration of positive manifold pressure, through all the transient conditions of "normal" drive cycles. The Callaway Silverado's performance and drivability are nothing less than spectacular. The development project is now in the final stages of in-vehicle testing and validation; final horsepower and torque rating will be released very soon.

Developing the new Silverado/Sierra engine management calibration is especially important because the 2014 Corvette uses much of the same powertrain management architecture and controls. Lessons learned in developing the Silverado/Sierra system have been extrapolated to the new Corvette platform. Consequently, Callaway enjoys a significant headstart in developing the supercharged 2014 Callaway Corvette and Silverado/Sierra 6.2L.

Development is also underway for Silverado/Sierra optional equipment, such as suspension components for improved ride and handling, wheel and tire packages, brake systems and interior upgrades.

Authorized Callaway Dealers are ready to take orders for the new Callaway Silverado and Sierra 5.3L Crew Cab now, with Extended Cab and Standard Cab models following soon. Callaway will introduce the supercharged 6.2L-equipped 2014 Callaway Silverado, Callaway Sierra and Callaway Corvette later this year. Tahoe and Suburban for 2014, and their GMC Yukon, Yukon XL and Cadillac Escalade counterparts, are carried over from 2013 with only minor changes.

      $17,000 for a supercharger and a remapped ecu?

      OK, I'll be the first to say it... 450hp out of a 5.3L with a 2.3L TVS? That's it? We're talking about the same blower that makes 600+rwhp on a 5.0L (non-Boss) Ford... Either the 5.3L is a dog, or they're running practically no boost through the blower.

        Callaway hasn't had time to work out the Programing and details. 450HP is nothing for a 5.3L with a blower. The LT engines are a totally different architecture than the LS engines they replace and obviously this supercharger package needs fine tuning.

          If it still requires tuning, then its no better than having Doug at the Amoco stick a blower on there. The whole point to buying a vehicle from a big-name tuner is that it is supposed to work as well as it possibly can.

          @ wilkegm: I suspect that this IS tuned... the issue is probably more related to fueling than the actual blower size. Simply put, the aftermarket now has to catch up with higher-flow direct injectors (vs. port injectors now used). Of course, Callaway may make an end-run around that by replacing the intake manifold and adding "supplementary" port injectors, but that'd cost more.

      Why is it so expensive? Putting aside peoples hate for the Tundra you still get 120+ additional hp from the TRD supercharger that you can get right from your dealer and financed in with the purchase of your truck. And I think that runs around $6-7k installed. This would be far more intriguing if it were $10k less. I'd rather just pay the couple grand option price for the 6.2L when it's available isn't that supposed to be around 420hp?

      Honestly, what's this for? Showing off at animal husbandry concourses! That's the problem with our American sports car industry; lack of focus. Same applies to the idiotic Corvette...6.2 liter of obsolete engineering in an amalgam of parts from other GM cars. Big cars that sound like farm tractors are not sports cars. Going super fast in a straight line is juvenile at best. Ohhhh, I just loved the idea of a Corvette emblem coming into the Tach above 5000, that's just soooo.......stupid.

        If you think an LS3/LS7/LS9 at full throttle sounds like a farm tractor then there is no hope for you. That or you've seen some badass tractors.

        Wait, to troll properly, you need to out in "Gubmint Motors" in your post somewhere. Especially if you're complaining about the "American Sports Car Industry"'s lack of focus when this is a post about an aftermarket tuner's pickup truck...

          @Rob, You couldn't afford a Porsche, AMG, or GTR with AWD and DCT. The Base price for a corvette is $50,000 which puts it in reach of 60% of car buyers.

        If you'd actually have AMG AWD money you wouldn't be shopping a C7. I wouldn't expect the Vette to ever get AWD, nor should it. It would take away from what it is IMO. What's next, going to suggest Ford make the Mustang AWD?

        I'm sure GM will lose sleep over some random dude demanding they make a car said random dude likely can't even buy to begin with. You want those things, go buy an R32 and throw on a supercharger.

      The Silverado does not look good. I don't know why many of you here criticized the Tundra when this is not good looking? TRD offers a supercharger for the Tundra with 500 hp for the 5.7 V8 which is more powerful and faster. I have seen videos for Supercharged TRD Tundras smaking Bentley GTs in a drag race
