 Allan thats not the way it works. A larger drive pulley/gear speeds up every 
driven item. A larger driven pulley/gear slows down whatever the item being 
driven is.

 If the pulley has a circumference of 1.75" then the timing belt must move 
1.75"  to achieve one full rotation of the waterpump, if the pulley is enlarged 
to 2" then the belt must move 2" to achieve a full rotation. Since the crank 
gear for the timing belt is still the same size the belt will still be moving 
the same speed for any given rpm but the waterpump will be moving at a lower 
rpm.

 Think about it...the camshafts move at 1/2 crank speed and the camshaft 
gears are 2x the circumference of the crank gear.
