Fan Belt types??

I have an old1976 Corvette. Traditionally I have had a 'solid' fan/
alternator/PS belt on it.

I see now that I am being offered ones that are 'notched' or have
'teeth' on them.

What to use and buy? What is the idea behind the notched belts? Less
material = lower cost? Heating/cooling is better? Less slippage?

I'm sort of the opinion 'if it ain't broke don't fix it', but more and
more I see these as replacements.

Input anyone????

TIA, BSA

PS: It seems to me that the notched belts are noisier.

Thanks, but the first link for me was dead.

The second, although interesting, uses refrigerator compressor belts
as an example. Not sure if the cost, noise, etc provides any benefit
over a regular belt for a car. I cannot say I noticed any extended
life.

The link I opened gave some figures for improved efficiency in the
neighborhood of 2-4% over the standard V-belt.

I would expect a notched belt to be noisier than a solid one, wouldnt
you?

But, if a company can pick up a few percentage points of economy,
at whatever level, without incurring any cost, there is no decision to
make.

Notched are generally a bit more efficient with power transfer. They
also stay cool a bit better due to the increased airflow the notches
allow. They also flex better and allow tighter curves as a result.

Notched on the inside gives better cooling.notched on the outside
gives better flexibility

What I am decoding from all of this: On a 30+ year old car with a 4
barrel carb and original engine, it makes no appreciable difference
aside from noise level and heat transfer. On that basis I'll vote for
a solid belt I guess.

thanks all! Interesting info.....

you will never be able to hear the diff in noise level by ear with the
hood shut. get the notched belt. It will work better on worn pulleys.
