    There are 2. One is a 2.8 that is a 10lb pulley and the 2.6 that is a 12lb pulley. Check your psi gage at about 5k and full throttle and you should be able to make out which one it is. I'm guessing it's the 2.6. I would hope there is also the extra tensioner pulley on there with it.

    They do also make a stock size one. I didn't even think about that. I have one sitting on my desk here. It has no part numbers on it. If there is no extra tensioner it's possible to have a stock one I guess.

    I would measure the front of it and then take about .2" off as the aftermarket pulleys are measured by the peaks of the ribs.

    I would not go by the boost guage as that is not terribly accurate.

    Thats true someone may have put a stock size on to trade it in since they wouldnt want to press on the stock pullie as most times its trashed pulling it off.
