Adriano is right
just think of it like this,
Velocitybelt = Angular Velocity of Pulley (basically speed that the pulley spins) * Radius of Pulley
Now since the crank pulley drives the S/C pulley, u know that the belt speed is the same for both (assuming no slip),
now since withyour UUC UDP the crank pulley has not been changed at all in size (or angular velocity obviously) that means that the speed of the belt is the same as stock. And thus that means that the angular velocity of the S/C pulley is the same as stock (with no UD puleys i mean) by the little forumla I wrote above.
