[QUOTE="einehund, post: 16036435, member: 67302"] I have seen the 2650 advertised boost reference by pulley size, but those all are assuming stock crank size. Is the 3-4psi increase with a 10% lower still the same on this blower, or does the larger size increase the psi to say 4-5? Also, is the safe psi still 19psi on pump gas, regardless of the size of the blower? I ask as the larger blower should be turning slower for the same CFM airflow, thereby reducing heating, resulting in the ability to run a bit more boost. I am just trying to figure out what combo I need. [/QUOTE]
