IMPROS

Hey man how are your doing! i was told you are the man to talk to about impellers. i am building a rickter xfs and it will have a dasa 950 8mm stroker, limited b-pipe,protec ingnition, 46mm dual carbs with r & d filter, intake grate and thrust trim system, i am currently running a 144swirl 14/17 pitch with a stubby cone. my buddy wanted to trade for his 11-17 hooker but i am not that smart with the impeller part of things. please let me know what you think.

dear impros i have a super jet 2009 and i was thinking of getting a new impeller but i have no idea what to put or the size so could you please help me my sj is stoke but am thinking of simple mod's like b-pipe intake grate
also am wondering about the cone does it worke ?

where is your 9/15 on your site...also my set up is b-pipe reeds, msd enhance is the 9/15 the best??

Question for you. I bought a buddy's (Phil Clemmons) 9/15 hooker that he used for an hour or so on a limited Superjet. I've got a full limited set up plus X Scream porting. About 2/3 into the powerband it feels like it's cavitating. Any ideas?
