What is the Internal Step up Ratio for a Vortech YSI 1600 CFM Blower? 3.6?

Thanks

Pretty sure it's 3.45. S-trims are 3.60

Did anyone get a final answer for this ?

Working back from info I found on another forum, I had thought 3.45 also.

Im curious as I have been supplied 86T crank with 34T SC for 9psi approx ( supplied by CAPA ). Just wondering what sort of SC speeds this would produce ?.
Id also like a SC pulley to take me to about 14-15psi.
