| Recommended Configuration for Top Performance: Our modified engines will achieve top performance with our pipe systems. Specifically, the BZx4 Ultra Modified Zenoah G260PUM will achieve maximum performance with the BONZÍ Race Performance Pipe. At a minimum, a quality, dry, race type (tuned) pipe is essential for all modified engines. Optimum performance will also be affected by your header pipe. For example, the BONZÍ BZx4 modified Zenoah requires a much shorter pipe than a stock Zenoah engine. Be sure to follow the manufacturer’s recommended lengths for tuning for your particular pipe configuration. If you have questions,do not hesitate to ask. | Many factors will affect the performance of a modified engine. These include (but are not limited to): hull weight and type (cat, v bottom, hydro, outrigger, etc.), propellers, altitude, humidity, whether it is being run in salt or fresh water, as well your individual setup. Contact our tech support 24/7 via e-mail with any questions. For a great deal, try the BONZÍ Power Package – which includes a Zenoah engine, Mounts, Collet, Clutch, Water Pump and choice of the Quiet Power Tuned Pipe or Performance Race Pipe Systems. Or opt for the package without Clutch & Water Pump if you prefer! |
