Hi,
I just saw your question to me in the Skater thread about speed in my Allison with the Merc 200xs I am running. I missed it then... Not out of rudeness, just didn't see it. Sorry!
I ran 98mph with a Mazco RE3 30p last season. This year I will try a Mazco RE3 32p and hopefully go +100. https://www.youtube.com/watch?v=Snz8wVPm2KE

Have a nice evening!
