The diameter of EVOSPORT PULLEY for C63 AMG W204(2010) is smaller than original,so my question is that:the top speed will be a bit slower than original,while using EVOSPORT PULLEY,is it correct?

Thanks!

 

The top speed of the car will not be affected by the smaller diameter of the pulley. All the accessory drive items will spin a little more slowly such as the alternator, air conditioner, power steering pump and coolant pump because the drive belt will be traveling at a slower speed.

 

Thanks,I get a lot ,I will use a EVOSPORT PULLEY instead of the original.
