Default Questions regarding the SOT roots kit

Hey guys, I'm looking at doing some fabricating and wanted to see if I could get pictures of how the supercharger is mounted on the exhaust side of the engine, the brackets themselves, and the intake. Now for some questions:
Does the throttle body go in the stock location or does it go before the supercharger?
Is the boost regulated solely by the pully?
I'm thinking that with the supercharger's and intake location it would be beneficial to jethot and wrap the header.
I know some of these questions might seem dumb, but I'm trying to get a feel if this project might be worth my time. I'm not trying to reproduce this kit, but rather make a better one for personal use.

I just posted my SOT car "members cars for sale" in the for sale section this morning. There is a crappy engine pic, but if you need some detailed shots somebody with a kit can take one for you. I will if I have time. Getting ready to sell the house so projects are crazy.

The brackets are fairly complex because there is a plate that mounts to the engine, then some sliding mounting blocks attached to the plate. It will not be easy to copy without one to look at.

Now for some questions:
Does the throttle body go in the stock location or does it go before the supercharger? Before the supercharger, then a dummy TB where the stock one was.

Is the boost regulated solely by the pully? Yes.

I'm thinking that with the supercharger's and intake location it would be beneficial to jethot and wrap the header. Yes, but several people have put a NACA duct in the hood.

I know some of these questions might seem dumb, but I'm trying to get a feel if this project might be worth my time. I'm not trying to reproduce this kit, but rather make a better one for personal use.

I have the SOT kit and it is still running well.

If you look in the Alabama forum for "SC kit install" you will find pictures of the kit components that might be helpful to you. Look on the first page.

Yeah they run pretty smoothly. I have had no issues that were not "unqualified tuner" related. I had an install thread. Not too many good pictures but there was a posted closeup of the dummy tb in it and some parts strewn about the floor.

I still have my install manual with lots of pictures in it. If I have time (again selling my house so super busy) I can try to scan some or something. If you are not in a rush and can wait a week or two it would be no problem.

If you tell us what improvements you want to make, most of us have fiddled with our kits over time, we might be able to give you a couple pointers.

I found the installation instructions. Send me a PM with your email and I'll send it to you.

I am currently working on an elbow to move the throttle body 90 degrees so it is not up against the firewall. I have a local guy with a Hass machine in his shop that is going to help me get something that works. Mine has been by far the worst I have seen when it comes from distance to firewall. The AC relocation kit also hurts with space.

I have a Fluidyne heat exchanger and I added to 6" SPAL fans to help with the cooling. My IAT are still up but I am open TB above the header so it is no telling how hot my inlet air to blower is. I've order 2 fluid and 2 air temp sensors to wire up to AEM. I'm going to have inlet/outlet of heat exchanger fluid and inlet/outlet of blower before intercooler. Should give me a better idea of heat soak.

If you get creative a jackshaft setup would be ideal. Also some of the new blowers have the pulley and inlet on the same side. Either way getting the inlet to the front would be a huge help on space requirements.
