Impeller question

[Joselurod]

I am considering changing my impeller to get some extra mph's. I have a 2010 GTX 155, which impeller should I buy? Another question.. I was told that sometime you lose on bottom end by doing this..is this the case with every impeller switch?

Usually the manufacturer websites provide an accurate description. They don't ALL hurt top speed. Some improve acceleration and top speed a bit, some just acceleration, some just top speed.

Which one to get depends on your wants - better everything, better top speed, better acceleration, etc

You want more speed?

Sell your ski and buy a 215 or better.

I was told that the top speed is governed and you won't get more speed unless you do adjust ecm. I have rxp 255 supercharged and the top speed is 113km/h or around 65mph which is somewhat disappointing but I was told by the dealer the top speed on water here in Canada is 65mph so that's what the machines are set up for.

An '08 RXP-X?

The ecu isn't "governed"

The stock intake grate is...HUGE. It's the main reason you're being kept below 70mph. It's a huge drag. Replace the stock intake grate with an R&D...replace the stock prop with a 15/22 Solas.

73mph....+/-

Improve the stock air intake with a 4" up front or Riva rear air set up.

One last thing....dealerships aren't called...stealership for nothin. I wouldn't believe a thing they told me about my ski.
