With the 3.33 pulley and restrictor, I was making 12lbs on my stock cube motor. With a 416, you may need the 3.33 pulley and no restrictor.

I think the new ecs kits come with a bigger supercharger pulley than the 3.33

It depends on who it is purchased from, some of our southern dealers prefer a larger pulley and a smaller restrictor due to higher outside temp averages.
Barnetter88, you can just open up the restrictor to your desired boost, wouldn't cost you a dime other then your time and checking the tune over. I hope that helps. |
