Job well done. They under promised and over delivered!
2014 CALLAWAY CORVETTE HP, TORQUE UPDATE: 627 bhp, 610 lb-ft
Callaway engineers have finalized Callaway Corvette powertrain
management system calibration, following comprehensive vehicle testing
and validation. Based on dynamometer testing with production-level
components and calibration, the 2014 Callaway Corvette has been rated
at 627 horsepower at 6400 RPM, a 167 hp increase over the stock
Corvette baseline. Peak torque is rated at 610 lb-ft at 4400 RPM, 145
lb-ft greater than the stock LT1's output.
Callaway uses SAE certified power correction to compute horsepower and
torque for its cars and trucks, employing the same method that
Chevrolet and other vehicle manufacturers use. Using standard
corrected computation for power and torque, as many aftermarket
manufacturers use, the Callaway Corvette SC627 would be rated at 657
hp and 639 lb-ft of torque.
The graph shown below illustrates the power increase produced by
Callaway's unique, new-for-2014 supercharger design (pat. pend.) and
single acoustic chamber exhaust system. Note that horsepower increases
consistently from idle to maximum engine speed, and avoids peaking at
6000 RPM. Note the broad torque curve, with output exceeding 500 lb-ft
(SAE) at only 2200 RPM.
The supercharger system includes Callaway's new intake manifold
design, its new intercooler design, and a 2300cc high helix angle,
four-lobe rotor pack. Callaway developed the new long-runner manifold
to increase mid-range torque, producing 57 lb-ft (SAE) more than last
year's Callaway Corvette. The engineers also devised a new intercooler
system with three discrete liquid-to-air cooling elements, providing
unequalled inlet air cooling efficiency. Plus, by extending the
supercharger housing through the hood, convective heat transfer yields
additional reduction of inlet air temperature. Reducing inlet air
temperature provides more oxygen molecules for a given volume of air,
increasing power while helping to prevent engine-damaging detonation.
However, supercharging inherently increases air temperature as it
increases air pressure. Unchecked, this can result in negating the
supercharger's positive effects. Callaway's new intercooler
configuration practically eliminates this temperature increase, as
proven repeatedly during product development testing on the dyno and
at the race track.
NEW CALLAWAY CORVETTES IN PRODUCTION
As you can see in the photo below, Callaway technicians haven't wasted
any time. Now that calibration development is completed, Callaway
Corvette SC627 production has commenced. Production cars have already
begun shipping from Callaway's Old Lyme Connecticut and Santa Ana
