Contacted ECS regarding pulley sizes, and he said that all the unrestricted kits that gets sent out has the 3.7 pulley size. I’m kind of confused since on their website it says 3.47. On top of that he recommended not dropping down in pulley size since it’ll overdoing the sc...

What size sc and crank pulley are you running now? And what size did you want to drop down to?

Hmm... i think i recall you saying you were happy with your power level. Hahaha sounds like you got the bug! Horsepower junky in the making. All Im gonna say is... you should have gone with ess. That is all. Carry on.

I think I was at 48k with the 3.6 pulley. I believe 55k is the max on the 1500.

TheFlyingBananaSS · 01-26-2021, 11:58 AM

I do have friends who run the 3.47 on the 1500. But I'm not sure of their crank pulley size. Also the ECS website hasn't been updated in a while.

I’m content, but since I’m going through a new tuner, I might as well squeeze everything out of it. So if I could pulley down make 800 or more...then I’m done.

Their website sucks. I’m on stock crank size.

TheFlyingBananaSS · 01-26-2021, 06:26 PM

Definitely a 3.6 Chris recommended it to me when I was at their shop. I'm on stock pulley too and getting 9psi with the restrictor plate. Chris said if took the plate out I would get 12-14psi. The kits used to ship with the 3.47 They probably changed it to keep people from over spinning it. Mine came with the 3.7

What kind of psi are you seeing with it?

RupertPupkin · 01-26-2021, 07:42 PM

Bananas... you willing to part ways with your smaller pulley?

Nvm. Misread it.

RupertPupkin · 02-01-2021, 12:46 PM

Had a chance to chat with Doug @ ECS. He said doing 3.47 would put me at around 51000 rpms at 6600, and of course max it out if I rev higher which I’m planning on doing.

If I swap the pulley at home, would it be safe to drive 1.5 hours to my tuner? I’m assuming yes.
