That is the standard ratio for the underdrive crank pulley. The race pulley is about 50% underdrive.
With just the street underdrive crank pulley you'll notice about 80% of the gain from the complete set with fewer problems such as low battery charge and hot engine temps idling in the summer. You will, however, need a shorter belt. The complete set is set up to use the factory length serpentine belt.
Buy it and run it, you'll be glad you did. It's cheap hp with virtually no driveablilty problems with the added bonus of longer accesory life.
