Product Information

Updated 4.30.11

Power Flow Systems, Inc. has been hard at work developing a potential exhaust system for the Beechcraft Bonanza. This will be our first six cylinder exhaust system, so all existing PFS exhaust designs would not come close to fitting. It requires a "clean-sheet" design to fit inside the cowling while accommodating the necessary length for increased performance.

PFS is happy to announce that we have designed an exhaust that meets all of our design parameters and delivers substantial improvements in the performance of the Beech Bonanza. At this point, all of our developmental testing has been done on only one aircraft, our A36, N9066S with an IO-520 engine.  The exhaust and certification are planned for Bonanzas configured with the IO-520 engine first, with the IO-470 and IO-550 engines to follow.

Based on over 3700 Power Flow equipped aircraft flying today, we feel that the performance we are seeing should represent "the average" aircraft. As is normally the case, some aircraft will respond even better to the tuned exhaust, while some may not respond quite as well.

Due to the unique design, we do not want to fully commit to the high cost of FAA certification and production tooling of the exhaust unless a significant number of Bonanza owners will commit to the purchase of the exhaust.

Number of IO-520 Bonanza Deposit Holders as of 4.22.11: 7

Remaining number of deposit holders needed for PFS to commit to certification: 23.
