PitPop, how does the Alpha Econo motor perform? Have you or Cody actually tested it? Is the 2066 pipe "THE" pipe for it?

I ask because a friend and local racer, just picked up Orion as a sponsor.. I've seen his "CRF" Alpha on both Buggy and Truggy with 2013 and they RIP.. Although it seems a tad soft on truggy, even his words, but it is still enough. I am considering picking up a couple of the Econo "Alphas" for next season, but am torn, as Mike is the only guy around here that has ever run an Orion, and he just picked them up. I'll be running them in buggy only. I last ran RB S5 and eXtech .24 in that buggy.. RB let go after 6+ gallons, ran my old truggy engine for something to race.

What are the differences in the Econo and CRF Alpha motors? I know the CRF Alpha has the slotted crank, but otherwise what are the differences?

Thanks in advance..
