My people, I've decided to upgrade my pulley setup for my ECS1500 Kit and currently have a DP Direct Drive on it. Being that said, which pulleys do I need to upgrade? I'm thinking of IW for pulleys. Side note, should I go 10 rib if I plan to swap to a 2200R next year?

Thanks in advance!

Blower pulley and crank pulley.

If you go 10 rib you need to order the spacers/etc from ECS, and get other parts, otherwise it is already setup for 8 rib. If you are going to a 2200R I would go right to a 10 rib.

Unreal, thank you. You are the man. Do you know if the stock ECS kit on a 10% OD crank pulley would be to much for the Novi 1500? I'm going to uncork it as well.

Goto vortechs site, plug in your pulley sizes, and find out.

I run the IW 10% OD crank pulley and the ECS 3.25" blower pulley on my 1500. I'm right at the limit. But it also makes 14.5psi with the filter on. So there's that.
