Talking Re: Eurocharged Performance...who the heck is that??
I wanted to bring up a point that the accessories have to follow the belt speed and a bigger take up pulley( it does the pulling) raises the surface speed of the belt. The only reason that the water pump pulley is smaller is to provide physical clearance between the W/P pulley and crank pulley.

There is no way to change anything, easily, that will UNDERDRIVE the water-pump pulley. In a way; it is a benefit as the somewhat faster water pump allows greater water pumping with the cooling benefits.

BTW the 181 pulley is only 1.6% bigger than the 178 and the 185 is only about 3.9% bigger than the 178. Overall the 185 is a 19% bigger - FASTER - than the stock 155 crank pulley. Stress wise I feel that the supercharger is forgotten in all of this as it is using up to 50 horsepower to blow air toward the motor. That on a belt driven pulley shaft that is but 2+" in diameter turning some 15,000...............yeeeeaaha!

Weekend #1, enjoy and party safely.........W DY
