Measuring Impeller speed Guys trying to figure my impeller speed of my D1SC, on my 383.
I have yet to get my Blower pulley and my Crank pulley but i was told I needed to get a 7.625 Crank pulley and a 3.4 Blower pulley, I will be running a SDCE tensioner setup, hoping to see around 12-15lbs.
This is what I came up with
Crank / blower ratio = 7.625/3.4 = 2.242647
Drive ratio * internal ratio = 2.242647 * 4.10 = 9.19
Max rpm * total stepup ratio - 6200 * 9.19 = 57008Impeller Speed
Max impeller Speed for the D1 is 62000
Here are the Blower specs from Procharger

My Question is Should I try to spin around 60000 from the blower or should I just keep it around 57000. How much am i leaving on the table??
Does anyone know the pulley size RANGES for both Blower pulley's and Crank pulley's I was told 3.4 is the lowest we can get for a Blower Pulley???
