Thread: what prop?
07-31-2012, 05:19 PM #1
Guys hello i have a RXT 215 with X charger, air filter, poweshot and machined improvement of the airflow to the throttle body ( sorry for my explanations for this, my engilsh are not so good). During 75 fahrenheit (outside temp) i get around 8000-8050 rpm and 66 mph (sea water). The problem is that most of the time i use my ski at summer and at around 95-100 fahrenheit where i get 7700 rmp and 65mph (both with gps, speedo always shows 70mph) due to hot outside air. I was thinking of changing the prop in order to increase wholeshot and gain a couple of hundreds in rpm, would the srx-cd 13/18 do the job? Take into account that acceleration is what i care for cause top speed cant be obtained at all times due to rough water conditions

Hey mate, I think you might have an underlying problem somewhere. You should be on the limiter with an X-charger and stock prop.. 14/19 would be the right prop for you set up I would think, but you need to investigate to find why your rpms are so low.

What year RXT? your r's could be okay....but your speed is definately down. Salty conditions too?...could be a whole bunch of dirty clogged stuff causing the loss in mph.

If it is just a case that it is too choppy to determine max rpms, then that's a different story.

If you were to take the X-charger off and the air intake, and put the stock parts on, you'd barely be turning 7300 rpms in the Summer. IMO, something isn't quite right.
