Plenum owners, feedback please
Lardog's Butt Dyno
The X-51 Power Kit and the Plenum don't work together. The x-51 Kit has a completely different intake then the stock 3.8 motor.
Thats what they are claiming. There is NO WAY 18hp.
This is a link to what appears to be an independent test of a 997S with a Cargraphic exhaust and plenum. There are dyno graphs of the car stock, stock plus Cargraphic, stock plus Cargraphic plus plenum.

The plenum appears to add 11BHP (wheels) and 14lb-ft torque (wheels) to the Cargraphic-equipped car on 91-PON Texaco gas. The exhaust and plenum together add 30BHP (wheels) and 20lb-ft torque (wheels). Very nice increase indeed for aftermarket parts.
