Relocating the Procharger
Ok, I'm in the process of making a new bracket for the D1SC on my '95 LT1. I'm going to install it on the driver side, where the alternator usually sits. The main reason for this is because I'm running a cog system (was Bruce's) and I was looking at some of Procharger's install and I like the way the belt is routed (compared on how it's installed on the LT1). Also preparing for a larger s/c in the future. Sometihg like this(skipping the waterpump of course)
I'm going to FMIC from Procharger as well.
But recently I learned something that I didn't know, something about s/c clocking. I've tried to contact Procharger via e-mail, but it didn't help.
So what do you think and what should I do about the positioning of the s/c?

There is a fair amount of room in that location for a supercharger.
The control arm mount and hood support rail basically define the barriers.
You have about 10- 10-1/2" of vertical space to work with between the control arm mount and the hood (slightly less in front and slightly more towards the rear as the hood slopes upward).
It may be a bit of a challenge for the discharge tubes to clear the hood.
What is the scroll diameter of a D1SC? Hopefully it will fit in the available space.
From the specs it looks like 9" volute diameter. It should fit.

you can mount it with no problems just clock it so the slinger is down in the oil.clocking it, is easy from what i heard .if you call procharger 3 different times and ask them the same question you will get 3 different answers .just clock it your self and mount it. its very easy to do from all i have heard about it ..
Yesterday I did open the s/c and let me tell you....it looks very easy.
Just pull it out and replace it in one of the empty holes...
But what about the dip stick? Should it be replaced also to the other side???

Something to think about....
If you are planning a larger SC in the future, make a bracket now to support the larger SC. The D1SC has a 9" volute, while the largest ProCharger that will fit in the C4 has a 9.75" volute. I have placed the larger 12" volute, but it requires major cutting of the hood (not recommended). The issue is that as the volute gets larger, the SC must be rotated away from the shock tower and closer into the valve cover and up towards the hood. My D1R sits within 1/8" off of the valve cover, and required minor trimming of the hood. The original D1 (or D1SC) mounting bracket from Procharger for a traditional sbc is a great place to start.
BTW, if you talk to ProCharger. they will tell you that a D1 (D1SC) is the absolute largest Procharger head unit that will fit in a C4 vette. Though they may mention that there are individuals who have custom installed larger units (I was in talks with them at one time for the bracket drawings for both R units).
Let me know if you have questions.

You do want the dipstick to be at the top of the housing, as the dipstick also serves as a breather. Bob

First of all... Do you know if the bolt patterns for all the Prochargers are the same?
The thing is that your s/c is a std. rotation, right, but I think staying with a reverse rotation allows you to move inwards to the engine and to the front.
For now, I'm going to try to 'flip' the bracket from the pass. side to drivers side, something in that direction, staying inside the control arm mounts.
I was looking at some cars with the s/c right in front of the engine, running wide cog belts, F3R's...
It all depends of how long this engine will hold together...
