I never read that anywhere or perhaps I missed that point.

Fortunately the car is rarely stationary for long, no traffic jams on my local routes, so I guess I'll try it out and see if I can live with that.

Do you know what the original pulley diameter is by chance?

I'd be interested in calculating the rpm difference that the accessories will see.

No issues with water pump speed at idle I hope as that is the more important thing.

I did buy a lower temp Thermostat and a new water pump that I will install while I'm in there as well.
