Topgunz - air to air upgrade

TBatt

My 8psi pulley is silver and most that I have seen on the forum are silver (bare aluminum). The color is just a coating (anodizing) and should not effect performance. The "high traction" pulleys are often bead blasted for a more aggressive "bite" of the belt surface. I'm not sure how effective this treatment is over time.

One thing that I have noticed on the micro-v belts is that the ribs are fairly wide compared to the pulley groove. As the belt is put under tension the ribs are pulled into the grooves (standard V belt workings) and increase the surface area/traction. They do reach a limit when the force is greater than the traction. You gotta remember that a SC is drawing somewhere between 50 and 70 hp to create the boost we so love.
