so.. what exactly does the light pulley do as perfomance? also, how do you know when the tension is good enough? just eyeball/feel till it's tight enough?

It reduces rotating mass, which should make the car feel a little more athletic / rev easier.

As far as the tension goes, I just felt the tension of the belt before I took it off, and made sure it felt the same when I put it back on. You want it snug so it's not going to come off, but you don't want it so tight that you can't press it down a little bit.

The pulley was installed on the STi that i drive, Ben's method of eyeballing the tension on the belts worked fine as i have had no problems with the pulley in over a week so far.

As far as performance gains, its enough to be noticeable in my opinion. The throttle / pull in 2nd and 3rd feels a bit quicker.

The HSPN garage :D.

A video review of that F430 in the background is coming soon ;).
hahahaha. I LOVE the 430...I'm hoping either that or the 360 will be the first Ferrari I own. It's a ways off still though.

I could watch HSPN installs all day. I don't know why, but I have watched the dead pedal install 3 times just because I get bored sometimes.

Question

There are issues with other cars (my BMW 3 serries for instance) where replacing the stock pulley causes crank dammage long term.

I hear this is not the case on the Subies. Is it true that the stock pulley does not act as a dampener? Of course it will still act like a dampener to some degree in that it has mass, but if it is just a heavy and evenly weighted pulley then installing a light weight one shouldn't be an issue.

Any educated opinions on the matter? The only thing I have herad so far is "We've sold xxxxx of them and haven't heard of any issues etc"

Yet another great video! I have watched all of them and they all rock!

I wonder if you could just use a parking brake to keep the car from rolling instead of having someone apply the foot brake?

I am also wondering why there are only lightweight main pulleys that everyone makes? Wouldn't you want to replace the alternator and power steering pulleys as well?

With the parking brake on and a stopper behind the rear wheel I ended up rolling the car OVER the stopper when trying to break the pulley bolt. You might be able to do it, but I would recommend a foot on the brake.
