My paperwork from ATI does not list what pulley size they sent me. I want to confirm the boost level.
Says 4 25 on the pulley

a particular size does not equal a particular boost level. Engine size, heads, cam, etc. all will change how much boost a certain blower and pulley combo will make. What blower is it and on what engine? On a D1SC that pulley made about 10 psi on a friends 406.
By the way, a 4 25 is a 4.25" pulley.

Thanks Jody.
It's a D1SC but what bothers me is that my paper work shows SPEC NEEDED for the boost level. I want to make sure it was built correct.
