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.

John, I wonder what they will do with the Z06 when they get their hands on one, 750hp to 900hp? Now NASA will have to get involved with all these rockets running loose on the streets!

Very cool!!! That's a nice increase in power and it sounds like a very honest assessment as well.
