    I have both. A lot more torque in the Tornado.

    vortex = single ring piston

    Tornado = double ring piston

    I don't think it is a quality issue, i believe it has to do with the need of 2 rings on larger displacement engines and more compression. Basically you don't need 2 rings on those srm-210 and other smaller engines.
