Not necessarily I think?
How is the ESS VT2 system driven?
The aircon pully uses a different belt (and part of the pulley) than the belt that drives the waterpump and alternator. With most systems that's the belt that is also used to drive a supercharger.
The crankpulley has 2 seperate diameters, so obviously you have to change both diameters to change both belt speeds.....
The alternator, waterpump and steeringpump are I think much less sensitive to max rpm as they are very simple mechanically speaking compared to an aircon compressor.
So first you have to get the specs for the new crank pulley if you think of changing it.
