You got it .... the "updated" OE pulley is the rearmost pair .... the one that is deleted when the RS hub is installed.

Like I said guys. If we had pictures it could probably answer a lot of our questions.

For what it's worth, here's a snapshot from their website.

Here's what they have to say about it:
Serpentine fan belt conversion - Porsche 1995-98, 993 with A/C
$615.00
We have the cure for broken or tossed fan belts, and faulty belt sensors on the 964 & 993 Porsche engines. This conversion kit replaces the factory V-belts for the fan and alternator to a serpentine belt and spring loaded tensioner.

Does this help anyone?

I have a dumb question after looking at this. Does the tensioner also serve as a belt sensor? I don't see it in this picture.

No you loose the sensor but because there is only one belt the alt light will come on if you throw a belt.

I looked into the clewett kit and did not like the size of the bolt that held the tensioner. It looked undersized for the spring load IMHO.

I opted to use Jerry Woods dual pulley RS kit but had a custom crank pulley made so I could run AC.

I was throwing belts at the track like crazy before the upgrade. Many different Porsche wrenches signed off on the tension/alignment and yet they would still fly off. Have not lost one since the upgrade.

I do not know who you spoke to that told you that because it uses a stock size A/C belt. If it needed a smaller one Clewett would have included it in there kit.

The guy at Clewett told me this because he needed to use a smaller diameter pulley to clear the tensioner. Maybe you can adjust it out? Not sure but I was just going off what he said.

Kevin,

Here are two pictures of mine. Engine is just going in so this is a good time to look.

This is a full race 3.8 RSR setup so no AC, heat, Power steering, etc. The AC bracket is basically a spacer.

I just threw a alternator belt today at the track. It gave a abs and alternator/batt light. Why did the abs light go on?

Now it seems the clewett belt makes sense. The belt I threw was new. Hmm...
