    horsepower rating:engine size

    OK, so I noticed the new RXT-X has been upgraded to 260HP, but the engine size is still 1494CC. I know there are many factors that go into the horsepower ratings, but since I'm not a mechanic, it makes me wonder just how far BRP can push their engines without completely redesigning a new one.

    I was talking to a mechanic in my area and he mentioned that the Seadoos are working very hard to get the same horsepower out of the 3 cylinders as the Yamaha in 4cyl. He mentioned that the Yamahas are going to be more reliable in the long run.

    Ok, so BRP increased the horsepower rating by 1.9%. Big friggin deal! Since the pumps are less than 50% efficient, the new BRP engine has about 1% more power. Big friggin deal! When they increase it by 25%, that will be A BIG DEAL. That will happen in around 25 years.... Ron

    True, but when you consider the GTI 130HP engine has the same displacement as the RXT-X 260, that's a 100% increase in HP on the same engine!

    1: seadoo plays on the error allowance for these motors.. someone posted rxpx 255 dyno'd at 232 hp. So when they advertise 260 it really doesnt mean shit.

    2: its quality of the engine that matters when running forced induction and comparitively speaking, seadoo makes a pretty darn good motor

    3: who gives a shit how "hard" something works as long as it doesnt break and the performance is there.
