Digi-Tec 57mm info & help

[jlzf]

Hi,

This is my first post, and I’m sorry if this has been spoken before, but I couldn’t find any conclusive info.
A friend of mine had sold his store goods. After searching for something interesting, I’ve found a Digi-Tec pulley and some bosch spark plugs for the Mini Cooper S. Unfortunately he couldn’t give me any information regarding this.
Can anyone give me any info regarding these articles? Its power and torque output? Does it need a new belt? I assume the remap it’s a must have.

The only thing written on the pulley is Digi-Tec 57.

Any help would be great.

Best regards,
João

If 57 refers to the pulley diameter then it's slightly (1 mm) larger than the JCW pulley.

You can run a stock belt with this pulley. An ECU remap is not necessary but would provide more performance gain.

Randy Webb quotes 16 hp and 11 ft/lb gain from a 15% reduction pulley.
