It's just a spacer that allows your fan to turn at all rpm's...not a good idea as some stock Corvette fans are not designed to operate at certain high rpm's without a clutch...like my 78 7 blade...I would think you must consider the type fan first.....

Why do you think any GM fan cannot run at 6500 RPM (plus some design factor)?

I thought the clutch fan system was strictly for improved efficiency and reduced noise when the flow is not needed.

The pitch of the fan shouldn't make a difference for structural integrety (the speed it explodes) and the pitch would only effect at which speeds the fan best moves air. A fan with a shallow pitch won't move as much air when turning slowly doing better at higher revs, while an agressively pitched fan will not flow as much air at (some) high speed due to flow separation at the blades.

He wasnt saying it would explode! He was saying (as you said)some fans are not designed for high speed.

I had one that was locked up (bubba style) it made so much noise that sounded like a truck. I would guess that non-clutch OE fans have less pitch.
