Because the identify suggests, Callaway’s efficiency therapy for the Camaro SS takes the 6.2-liter, direct-injected LT1 V8’s output from 455 horsepower and 455 pound-feet of torque to a wholesome 630 hp and 610 lb-ft by means of an Eaton supercharger, a cold-air consumption, and customized software program tuning. The Callaway bundle is out there for any Camaro SS, no matter whether or not energy is distributed to the rear wheels by a six-speed guide or an eight-speed automated transmission, and each gearboxes stay mechanically unchanged from inventory, as Callaway’s engineers say there’s sufficient headroom constructed into the inventory to deal with this degree of output.
In contrast to with its fifth-generation Camaro SC572, Callaway has chosen to go away the chassis largely untouched right here, and the aesthetic tweaks are decidedly refined as nicely. That additionally stands in distinction to Chevrolet’s personal method with the upcoming 650-hp Camaro ZL1, which is ready to land in showrooms this winter and represents a full dynamic makeover for the automotive, not simply added energy. As well as, Callaway’s supercharging technique differs from GM’s in just a few essential methods, making the SC630 bundle an attention-grabbing different to the LT4-powered ZL1.
Apart from the highest of the supercharger peeking out of the hood and some badges, there is not a lot to tip off events to the SC630’s true functionality. Though the amount from the quad-tipped exhaust is cranked up a bit versus a inventory SS system, the SC630 retains a reasonably low profile from an auditory standpoint as nicely and retains the manufacturing unit dual-mode setup. Blower whine is nearly non-existent each at idle and when pulling by the rev vary.
However from behind the wheel, it solely takes one dip into the throttle to detect Callaway’s handiwork. Initially developed for the Callaway Corvette SC757, the GenThree supercharger system on the coronary heart of the SC630 makes use of a TVS2300 Roots-style blower. It is a 2.Three-liter unit relatively than the 1.7-liter one which GM makes use of with the LT4, which implies that Callaway’s blower does not have to spin practically as quick to generate related ranges of enhance, and in flip it generates much less warmth doing so. GM truly used a 2.Three-liter supercharger on the C6 ZR1, and the phrase inside engineering circles is that the LT4 modified to a smaller blower to adjust to new crash security rules relatively than for any efficiency motive.
Warmth is a major concern when supercharging, as extreme temperatures can lead to a steep drop off of energy as a consequence of supercharger warmth soak or digital fail-safes designed for self-preservation when inside temperatures hit essential ranges. Together with selecting the bigger blower versus the LT4, Callaway sought to deal with these points with a novel triple-element intercooler system that consists of a major intercooler on the prime of the supercharger and a pair of secondary intercoolers on both facet of the rotor packs. And the supercharger protruding of the hood? It is not simply there to look neat – the cutout serves as a warmth extractor.
These efforts appear to have paid off, as energy remained constant and engine temperature steady all through a number of prolonged runs alongside the quick, twisting tarmac of the Angeles Forest northeast of Los Angeles. However with none adjustments to the suspension, brakes, or contact patch, one may rightfully count on the SC630 to be a handful when pushed exhausting, significantly in something aside from a straight-line dash.
Thankfully the brand new Camaro chassis is such a stable basis that the SC630 places the ability down with no points, and the newfound grunt does not merely equate to incinerated tires. Traction management will step in when wide-open throttle is requested at speeds under about 60 mph, however any interventions it made when launching this automatic-equipped take a look at automotive felt comparatively seamless. After all, like something with output on this league, cautious throttle inputs are required in case you’d desire to not find yourself in a ditch.
Nonetheless, when the roads get demanding the inventory chassis elements begin to present their limitations. It is a lot simpler to get this SS as much as a felonious tempo, however when you’re there the suspension appears a step or two behind the powertrain, even with the Camaro SS’s adjustable dampers dialed to their sportiest settings. The identical goes for the brakes and tires; though the factory-optional six-piston Brembo brakes and Michelin Pilot Tremendous Sport tires are undoubtedly succesful elements on a inventory Camaro SS, they’re much less at house dealing with the charges of velocity that the extra 175 horsepower can generate.
Even though setting lap data is not the Callaway Camaro SC630’s major focus, it is nonetheless a riot to drive this factor quick. With none vital mechanical adjustments exterior of engine output, this bundle will possible enchantment to these seeking to bolster their Camaro’s drag racing chops relatively than total dynamics, although it is price noting that the inventory SS is not actually a slouch in that regard to start with, and the SC630 solely provides about 80 kilos of heft to the entrance of the automotive.
Callaway’s a long time of efficiency tuning expertise have been additionally evident from the dearth of even a hiccup from the SC630 all through our time with it, each when pushed exhausting and when confronted with lengthy bouts on crowded freeways. That most likely explains why Callaway features a three-year, 36,000-mile guarantee with every Camaro it sells (a five-year, 60,000-mile prolonged powertrain guarantee can also be obtainable), and Callaway’s modifications don’t nullify GM’s personal guarantee on the automotive.
The SC630 therapy prices $16,995 on prime of the worth of the Camaro SS donor automotive; it may be optioned onto new automobile purchases by Callaway’s community of taking part Chevrolet dealerships or put in on buyer vehicles on the firm’s services in California and Connecticut. That will seem to be a giant ask for what boils right down to a supercharger package and a few badging earlier than the addition of any optionally available extras like Callaway’s distinctive nine-spoke solid wheels, however there’s one thing to be mentioned for peace of thoughts in relation to main engine surgical procedure. Callaway’s assurance that prospects will probably be coated in case one thing goes awry brings its personal inherent worth to the desk, and the SC630 bundle’s impact on straight-line efficiency is inarguable.
Callaway expects to construct about 350 of those vehicles per yr, and for some, exclusivity goes a great distance. Nicely, that and 630 horsepower.
