I had to go to using a smaller spinner than normal to cool my Plettenberg. Difference in temp was about 10 F, maybe a little more... looked funny at first, but then I got used to it. Kind of looks like the intake to a Mig 21.

Troy, I'll definitely be looking forward to seeing what you have come up with. Are you planning on coming up to Fresno for the Dist. Champs?
