Looks like your Canfields beat the TFTW's all to heck flow-wise. With that big of runners (192 vs. 170), be sure that you don't have too much head for your application with those Canfields.

Thanks Rev,

Wow the Canfield really out perform the trickflows at the lower lift levels.

I guess the Trickflows can go on my back up motor.
