180k smaller supercharger pully?

[tomka37]

Hi everyone,
Ive seen a smaller supercharger pulley on ebay the 30+bhp claim seems pretty ridiculous, but if it could squeeze 5 or 10bhp for the money it seems like an awesome mod. I mean the physics/principle seems sound. any thought?

Hi mate,

Just remember, installing a smaller supercharger pulley can potentially increase horsepower by a modest amount, typically 5 to 10 horsepower. However, actual gains may vary depending on your engine setup and tuning. Ensure you research the manufacturer's reputation and be prepared for possible impacts on reliability and longevity. Consulting with a specialist can provide personalised advice for your vehicle.

Hope this helps!

Depending on what car you have you can add 30hp or much more. It all depends on the current size of your pulley and how much smaller the new pulley is. Decreasing the size of the pulley adds rpm to the supercharger therefore increasing the boost that the charger makes. For example if you have the m113k engine ( the amg cars with the 5.5 supercharged engine) you can gain 70 rwhp with a 77mm pulley and 40 rwhp with the 83mm. A tune and supporting mods will increase the power output and safety as well.
