    MSX 150 Drive Repair - Thinking of a New Impeller - Which One?

    My 2004 drive needs a going through. Thinking I should review the impeller as mine has a few dings and some wear.

    Any recommendations on a differnt/better impeller? This thing could use some more speed. My 140 beats it and the 150 has the Stage 1 (or stage 2, i cannot remember) EMM from my Canadian friend.

    What say you?

    I have the standard impeller tweaked to keep it of the limiter, (stage 1) I have always wanted to try the Solas 13/19 but have not needed to replace the impeller.

    What RPM are you turning at WOT?

    Stock inter-cooler and stock turbocharger?

    Stock motor and turbo. Just the upgraded EMM and a lower temp. thermostat. Cannot remember WOT rpm from last year. 7800maybe. Whatever Desperado said it would turn is what it is turning after EMM upgrade.

    I will have to re-read those threads

    I vaguely recall that the thermostat temp was raised to keep the engine warmer, thereby increasing gasoline evaporation from the engine oil and reduce oil dilution from piston blow-by.

    Perhaps I am thinking of Desperado's work with the Yamaha engines...
