I’m looking for some help with the install on my REV400. I bought this used REV400 kit from @wirewheel.
The trouble is that when I install the S/C and bolt it flush with the intake, the alternator will not swing into position before hitting the S/C snout. It’s as if the snout bracket is about 0.5” too short. Sorry for the terrible photo, I should have taken a straight on photo, but you can kind of see this in the attached photo.
You can see the snout bracket that came with my kit in the last photo of the for sale post (linked above), as well as a photo below. I have an older version of the BOE install instructions that shows this style bracket, so I’m pretty sure it’s actually a BOE part, and not a custom piece.
If you check out the snout bracket that is currently shown on BOE’s website, it is a straight design. I’m starting to think that they changed bracket designs to reduce cost, or they have different bracket designs for different years of car.
Taking it a step farther, a friend with an installed kit took some rough measurements of his straight bracket and we compared them to mine. If we label the three holes from left to right, as A, B, and C, here’s what we found. For my bracket the B-C distance is about 3.75”. His is closer to 4 or 4-1/8” (difficult to tell when installed in the car). Now, remember that my bracket angles down, and his is straight, so maybe that’s the reason they are different lengths.
The bottom of the alternator is fixed in position by two BOE brackets that I recently bought. I triple checked that they are installed per the instructions, so I don’t believe that is the problem. I also checked the part number and appearance of my alternator and it appears to be the original alternator, so I don’t believe that is the issue. I was also concerned that the BOE intake manifold may not have been installed onto the supercharger per the instructions. Specifically, the instructions tell you to reveal as much of the S/C flange on one side (specified in the instructions) as possible. I popped the two pieces apart and tried repositioning them, to no avail.
I think this is the same or a similar problem as documented here, but I'm not positive.
Any thoughts, insights, or suggestions would be very welcome as I try to determine a solution.
