Thank you, though I believe Shardul's set up is probably better.
His pulley can be installed without removing and disassembling the front of the blower, making the install quite simple.
I wish mine were a straight bolt-on, but some fab work needed to be done in order for it to fit the hub.
The magnet is heavy but its NOT rotational mass. The plate that covers the magnet is the part that rotates along with the pulley and it does not weigh as much.
If I remember correctly the magnet is 13.xx lbs and the plate is around 1 lb.
I don't remember the pulley's weight, I'll check when I get home.

In order to clear things up I went back and weighed the components again. Here are the component's weight broken down:
-The hub and plate weighs 3.62lbs (rotational mass)
-The stock pulley weighs roughly 4.5lbs (rotational mass). I cant find the damn thing but I'll post a pic once it turns up.
-The magnet behind the plate is 3.52lbs (non rotational mass)
Total weight 11.64lbs (Rotational mass = 8.12lbs)
My new hub and 3.2" pulley weighs less than 1lb.

yes learned alot again. So it doenst makes a lot of sense to pull the magnet-assembly ?
Leave it on there, install the fixed pulley and ready to go?

Most of us already know the risks involved in swapping crank pulleys...

Excellent. So how is the result?
You care to elaborate on the safety features and does it indeed spin/react faster compared to a clutch type pulley?
I'm literally greedy about all informations (technical aswell) you have about this new system.
Cheers
