flywheel pulley size?

I need to know what size compressor flywheel pulley to use for a 3450 rpm motor compressor 1500 rpm dia. 13 3/4"

3450/1500 = 2.3. If the motor pulley is as you say 13 3/4, the compressor pulley must be 2.3 x 13 3/4 !!! I'd put a new pulley on the motor....

Unless the COMPRESSOR pulley is 13 3/4, in which case the motor pulley would be 13.75/2.3 ~ 6"
