Sorry I'm late to the game.Here's a little bit for you:
What you have is an Eaton M112. The Eaton 112 cubic inch compressor is the same as the Terminator and the Lightning people are more familiar with. The difference is in the casing of the housing. The Cobra has the nice little side inlet plenum casting, the Lightning has the well known over the top inlet.
The configuration you see was designed by Roush and sold through FRPP as the SVO unit. They are the same other than the brand cast into the top. In fact, some of the Roush cars got the SVO casting. This version was made to use the stock air inlet tube (or any direct bolt on CAI). The air is compressed, then blown upwards into the spider style manifold runners which feed into the heads. They were made to work the the stock NPI heads or the improved Roush heads (again also sold through FRPP as SVO parts). The SVO heads flow better than the PI heads - but pull a pretty penny these days. I'm told this blower also works with PI heads, but you must use the NPI gasket between the intake and the head to block off the proper coolant passages.This is (obviously) a non-intercooled unit. However, it's not a bad thing.
Most got the 6 psi pulley on them and were good for about 300rwhp/tq (a good jump over the stock N/A power levels). There were also 9 psi pullies back then, which were worth a few more hp/tq points. I've heard of an 11psi pulley, but I don't have a lot of information on them. Never used one. It looks like you have the 9psi pulley.
Some will talk smack about them because they don't understand them. I ran mine hard up to 240,000 miles without issue before swapping to a built bottom end. By hard I mean 110+ miles a day in Miami traffic (heat, stop and go, at speed etc...). I also ran it hard around the track down here. I love these blowers. They give you a great powerband and are awesome for a street or road course car. You aren't going to hit a 800 hp with it, but then again, how many guys really need to hit that mark anyway. On a stock bottom end, mine made 347/356 @ 6 psi.
Do you have more pics? It might just be the way I'm seeing it, but your snout doesn't look like the one's I'm used to seeing.
