I still suspect it’s an alignment issue.

 

i concur doctor.

even if it doesnt solve the issue should laser align all blower setups using belts.

it might still be the alternator or other pulley cause it maintains a faster inertia than the rest of the pulleys.

 

I had a belt chirp with the Whipple when I would let off quickly.

What was happening was my crank pulley was spinning ever so slightly. I found that out when I reached down to see if my crank bolt was tight and it was missing.

When I pinned the crank that chirp stopped.

 

Pull the belt off and flip it around and see if anything changes.

 

Happy to report that making no other changes besides going to a continental gator back belt in the stock Magnuson length of 109.8 inches completely solved the squeak it's now been about 500 miles and a week with multiple early morning cold start ups!

 

Have you smiled every time you fired it up and didn’t hear the squeak? Lol

 

Yes combined with an inner feeling of relief that I don't have to chat with my neighbor about why the "hot rod" (as he puts it) belt squeeks like a Taurus lmfao.

 

LMFAO

Well done.
