When it comes to selecting aftermarket embellishments for your Corvette, having too many to choose from is just about right. Project cars are never done, and Vettes in particular are considered blank canvases constantly in need of fresh custom touches. As Chris Perry, VP of global marketing and strategy for Chevrolet, notes, “Go to any Corvette enthusiast event, and you’ll have a hard time finding a factory-stock vehicle.”
In particular, when we find all sorts of stuff spilling out of that horn o’ plenty called the Specialty Equipment Market Association, or SEMA, show (which fittingly take place just before Thanksgiving each year), we know it’s harvest time. We gathered up a bushel basket full of choice items for enhancing both the performance and appearance of your Corvette. So enjoy, and don’t skimp on the gravy.
Under the Bonnet
Magnuson has long been a leader in positive- displacement supercharging technology for Corvette engines. The company’s latest offering boasts the added benefit of being able to fit beneath a stock C6 (LS3 or LS7) hood. Generating from 5 to 6 pounds of boost, this sixth-gen Eaton TVS blower is said to add 130 rwhp, along with substantially improved midrange response. A liquid-to-air intercooler, front-mounted heat exchanger, electric water pump, and intercooler-coolant reservoir keep intake-air temps in check for consistent performance. Even better, an integrated bypass valve allows the rotors to spin freely under light engine loads, minimizing parasitic losses and maximizing fuel economy. Each unit is backed by a three-year/36,000 mile warranty, and longer warranties are available optionally.
All Pumped Up
Give your ’08-’11 base C6 or Grand Sport the same forced-induction technology found on the ZR1 with SLP’s Positive Displacement TVS 2300 Supercharger. Available with a satin-black finish, this blower (PN 92010A) features a four-lobe rotor pack for optimum power and efficiency. SLP claims improvements in output of 145 hp on stock LS3s (from 430 hp to 575 hp). Each package includes a performance-optimized PCM tune, a new cold-air induction tube and high-flow filter, and all necessary hardware and instructions. All systems are 50-state emissions legal. (Note: A new hood, such as SLP PN 100025, is required for installation.)
Getting the Lowdown on Corvette Pans
Want your C1-C5 Corvette’s suspension to “get down,” but not so low that the oil pan scrapes? Canton has got you covered with its new SBC unit (PN 15-200T). This long-sump design, based off a stock early Corvette pan, is a direct-fit upgrade for a variety of chassis where ground clearance is an issue. Even though the pan has a lower profile than stock, it provides an increased, 5.5-quart capacity. Its 16-gauge construction, meanwhile, is TIG welded, double leak-tested, and gold-iridite finished. It’s even designed to work with the stock dipstick, oil pump, and starter, making it easier to install a newer-style engine in an older chassis.
Hellwig on Wheels
Hellwig’s new adjustable sway bar for C5 and C6 Corvettes is designed to improve street and track handling by decreasing body roll. The bar (PN 55732) measures 13⁄8 inches and comes with all components necessary for installation.
Singin’ in the Rain
Tired of water and wind creeping into the cabin of your C5? Metro Moulded Parts offers replacement roof-rail seals (PN RR 2009-H) for ’99 to ’04 Corvette hardtops. They’re built right in here in the USA and come with a 30-year warranty.
According to K&N, the company’s new ZR1 cold-air intake (PN 63-3080), improved the output of an otherwise-stock ’10 model by more than 27 hp at 5,948 rpm and nearly 20 lb-ft of torque at 4,288 rpm. While individual results may vary, these are clearly significant increases from a straightforward upgrade. (Note that while this unit is street legal in most states, it’s not CARB certified for use in California, or in other states that have adopted CARB emissions standards.)
