180K Smaller Supercharger Pulley

[tomka37]

I saw a smaller supercharger pulley on eBay, the 30+ hp claim seems pretty ridiculous, but if it can squeeze out 5 or 10 hp for the money, it seems like an awesome mod. I mean, the physics/principle seems reasonable. Any thoughts?

Just remember that installing a smaller supercharger pulley can potentially increase horsepower by a small amount, usually 5-10 horsepower. However, actual gains may vary depending on your engine settings and tuning. Be sure to research the manufacturer's reputation and be prepared for potential consequences for reliability and durability. Consulting with a specialist can give you personalized advice regarding your vehicle.

Hope this helps!

Depending on what car you have, you can add 30 hp or even more. It all depends on the current size of your pulley and how much smaller the new pulley is. Reducing the pulley size increases the supercharger's RPM, thereby increasing the boost pressure it creates. For example, if you have an M113K engine (AMG cars with 5.5 turbo engine), you can get 70 hp using a 77 mm pulley and 40 hp using an 83 mm pulley. Tuning and associated modifications will also increase power output and safety.

The M113K engine is my dream engine for the W203 frame.
