We have a nice indoor astro track (60'x100') and while one of my friends is running his 511 w/upgrade kit with 7.5T Reedy Sonic - he's running 26/91! And he wishes he had more space for a taller pinion, I'm running an LRP 6.5T at 18/87 (no upgrade kit) - I'm going to put the 91T back in it - but we're 8 teeth difference! Are the Reedy motors that much of an RPM motor vs. the LRP X12's? Or is the the revised ratio doing all the work? I had a 20T in it originally and she got up to 200* during one qualifier - added a fan, dropped two teeth and she's in the ball park now - 130*-160*.
Thoughts?
