Best Pulley

pbonsalb · 03-05-2013, 06:18 AM

I would use one that takes off the shelf belts. Rogue and MS are in that category, but I am not sure about Dinan, AA, or others.

Not enough participation here. Feel free to carry on without me. I just ordered a Rogue pulley set and very likely won't be checking back in here. It was a nice idea and I was keenly interested in comparing claimed gains vs. measurements for consistency. Oh well...

I will post the OEM pulley dimensions as soon as I have the pulleys swapped

.

So finally got my Dinan pulley installed, so I can report back the stock pulley dimensions. It is 120mm for both tracks.

Water pump and Alternator : 84.3%
Power steering and A/C : 81.2%

Single sided is off the shelf. We make the double sided belts and include 2 belts as an extra.

Bump. Are there any pulleys that don't underdrive the power steering? I have the MS pulleys installed and don't like the steering feel at low speeds so I will either be going back to OEM or trying another setup. Any recommendations?

BPM Servo tuning took care of power steering issues for me!

Can somebody confirm the OEM stock crank pulley is 120mm in diameter:
