Yep you are correct...still a tad above. From the info that PCTech has offered and from experience when the blower hits its max impeller RPM number its done no gains above that whatsoever other than heat. When I had my HO the smallest I ran was 3.4" and it gave me a tad bit of room to 7500 rpm.Not if he is on an HO setup. The 3.2 inch pulley in conjunction with the OEM balancer spins the blower right at Max recommended speed at around 7300 RPM engine speed.
