ECS pulley size
what size pulley and how much boost are you esc guys making? I have stock pulley that came with kit and the restrictor installed and making little over 6 lbs. I am looking to get around 10lbs. Does anyone have sugestions. Thanks

i thought that was the smallest pulley you could run

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

3.47 is the size the kits are shipping with now

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.
