Lightweight power steering pulley

The install wasn't too bad. Getting the lightweight pulley on straight was the hardest part. It's fairly straight- maybe some long term wear because of the slight wobble. But it's only like a gnats ass hair off.

Spinning the OEM pulley in my hand while spinning the lightweight pulley in my hand- WOW! There is a HUGE difference in rotational inertia. The OEM pulley appears to be bullet proof- literally.

Haven't actually driven the car since it's been installed, probably won't notice a whole lot of difference. But even if it's only a small amount- they all add up. Getting rid of rotational weight is VERY important- especially on a non-turbo Protege like mine.

I now have lightweight alternator, water pump and power steering pulleys with a lightweight and underdriven crank pulley.

How much improved acceleration do you notice? Does the engine work harder at constant RPMs to keep the new pulley up to speed? :unsure:

Just had to... I'm having a great time on a conf call, pissing people off.

You don't get Friday's off like the rest of us?

Who's "the rest of us" I'm still working today.

Although I did spend the morning getting a dyno baseline in, but i'm still at work.

Looks Great!!
Where did you buy it?
You seem to find great deals.

I got it from Medieval. They are a new vendor and I got it in one of the first runs directly from them. I think you can buy them at Protege Garage now.

so what does the old butt dyno say?

I'm liking it. It really feels like it revs faster now. I'll probably be hitting the dyno sometime this fall- but I'll have added several power increasers by then.
