I'd like to keep my engine looking completely stock, just wondered if it would be worth it to try and open up my stock plenum some? i have a good selection of porting tools and have cleaned up a few intake runners but never anything with a sharp curve like the plenum, not sure if i could do it effectively. or does anyone have a ported one they'd like to sell? ;). thanks in advance people. :)

Independent Dyno Testing On a customers 02 GT with my P&P plenum and Ford Racing 70MM TB, gains of 23HP & 21ft-lbs torque over stock were recorded.

With the P&P 75MM TB Potential gains are higher depending on modifications. With the exception of a inexpensive CAI system and high flow exhaust, less headers, this car was stock. I have the dyno results and will be happy to email a copy upon request.

In other independent dyno comparison testing my plenums produced more HP & torque than Accufab. These tests were performed by a Customer on a 1998 GT with PI heads & manifold. Two different stock out of the box 75MM TB's (Accufab & Dragon) were used during the testing with my P&P plenum and a stock out of the box Accufab Plenum. Regardless of what combination of TB/Plenum was dynoed, my plenum consistently outperformed the Accufab by an average of 1.46 rear wheel HP and 4.2 Ft-Lbs torque. Although the HP numbers are not astounding, it is a proven indicator that my plenums are competitive with the best aftermarket plenums currently on the market and exceed most torque gains.
