BlueOval Ralph: I have also been INVOLVED in many tests with the CTS-V, Camaro, and G8. The factory 87mm throttle body (tested at 1,100 cfm) is big enough to handle over 700 horsepower at the rear wheels. Some simple mathematics will prove that the area of a single 87mm throttle body and 2 63.5mm throttle bodies (CJ) are very similar in overall area and thus very similar in maximum CFM allowable and we have pushed the 87mm way past 700 horsepower at the rear wheels.

Also, the blower on the CTS-V will, in fact, run out of efficiency, but again, Lingenfelter, Hennessey, and others have pushed these blowers to the max and 15+ pounds will make 600-650 horsepower at the tires. Using the accepted conversion for IRS suspension vehicles, and the drag of a 6L80E automatic transmission, 650 horsepower at the tires is 808 horsepower at the flywheel. The CTS-V supercharger is equivalent to that of a 1900 Eaton. 800 horsepower is about the maximum but it is possible.

* at factory boost levels, 800 is not attainable.
