d-1 max impeller speed.
I have a 4.25 pulley on a d-1,making about 9# at max rpm,I want to install a 3.85 to increase boost.Will I over spin the d-1?

8 sec potential, 12 sec slip

Well, if you have the standard 8 rib procharger crank pulley that attaches to the ATI superdamper with the 3 bolts, you most likely have a 7.65" crank pulley.. But as mentioned, even with the 7.65/ 3.85 combo, you would be at 51324.5 impeller RPM, which is only spinning it to 82.78% of its max potential. To max a D1SC out, you would need to use a 7.65/3.4 pulley combo, and spin the engine over 6700RPM.
