[QUOTE="svt1111, post: 10003939, member: 88172"] TOB, I believe the reason for the omission of the dowel pins is to enable the installer the choice of being able to start threading the back bolts in place first, thus sliding the slotted blower holes under the bolt heads, in order to gain access with a wrench to begin tightening them later. Its because of the huge plenum that they do this, where on a stock blower you can access them easily. If the blower used the dowel pins, you'd then be forced to try and get the bolts started on your own, under the plenum, which is pretty hard. A group of my friends installed my 2.9 for me. I got to the shop after they had already gotten the blower on the lower intake manifold, and I was curious about the dowel pins too. That's when the fun started trying to get the back bolt ( driver's side) tightened down. It would make sense to introduce a ratcheting wrench that woult fit under the plenum so Whipple installers could have an easier time tightening that bolt! By the way, the 3.25" pulley is the standard pulley. The 3.0" is optional ( no extra charge). 3.0" is said to make around 17-18 psi. That is what I chose on mine. I noticed the kit does not include an injector upgrade, rather a fuel pump upgrade instead? That is a little curious to me, since I thought the stock injector was nearing full duty cycle around 590-600 rwhp. Maybe I was mistaken? Good luck, and looking forward to getting your first impressions of the drive. [/QUOTE]
