speed 1 rider vs 2 riders

Hi

just wondering if there would be any top speed difference if one is riding an rxtx 300 single rider vs two riders?

Does this scenario affect the top speed, saying both have identical pwc s?

I don’t have RXTX’s but GTI’s… But assuming identical skis and conditions (water, fuel octane, engine/supercharger performance, wear ring condition, and driver weights identical, etc.) an additional rider of average weight (150-200 lbs) does impact GTI top speed about 3 MPH in my experience. I would think even with RXTX power capability, there would be some impact with additional weight in a similar way. Those that have twin RXTXs may have a real world test example…

No difference in top speed on a stock machine since the 300s are gps top speed limited to 68-70 mph. Plenty of power to still reach that mark with an extra 200 lbs.
