looking for opinions on the "loudness" of my 671 blower at idle. Noticed at a car show this weekend there were several cars with same set up as mine some were silent at idle, some a little noise and then mine, video attached
I know whine comes from belt/pulley, belt is set loose as it should be, noise is relatively the same looser or tighter and position on pulley does not change it either. pulleys are square with one another, top pulley appears visually to be a bit out of round as it spins but not showing up on square as out of round, snout flange is square too.
With belt off no noise comes from accessories, blower and belt adjuster spin freely/silently.
I have had this set up for over 10 years, always made sound but would like to quiet it down a bit at idle (old age??)
I know 8mm belts are quieter but trying to figure out how some with 1/2 inch set up exactly like mine are quieter. I did not see any holes drilled in pulleys or any other difference on other cars. youtube shows the same, same blower set ups and some are screaming some not so much. Maybe my belt and pulleys are just wore down but don't like guessing by throwing money at issues, besides the car runs fine.
There is something different but what??
