Stewart Stage 2 Water Pump
I just received this water pump from Jegs (great service, btw), and noticed that the shaft turns smoothly, but seems to have more drag than I would have expected. So, I did a search, and found similar comments from other users of the same pump, along with fitment problems such as bolt-hole alignment and bracket interference. I haven't installed the pump yet. Does anyone have some recent experience with this pump's installation and function? Thanks in advance

I put this pump on my 10.5 CR 383, love it. I believe Stewart claims (off their website) that it only chews up 4 hp. So it seems to be a very effecient pump. Bolt holes lined up perfectly. However I did have to use a waterpump pulley shim (1/16" IIRC), not a huge deal, they're cheap.

OK, thanks for the reply. Did you buy the shim (if so where), or fab it yourself? Anyone else?

Re: Stewart Stage 2 Water Pump
I bought the shim, Mr gasket sells them in a pack of 3. I forget the sizes, but I used the middle one, 1/16". It was like $3-5. I got mine through summit. I'm sure jegs has it, and probably autozone or the like. You could easily make one, but for $4, I'll save myself some effort.

OK, sounds like it should be a good upgrade from stock. I'm hoping it will help the car run a little cooler on hot days.
