This is the last of the Paxton SN series blowers, based on the old Paxton McCulloch Supercharger used in the Studebaker Avanti, and Thunderbirds.
It had a self contained (no engine oil) Planetary Ball Drive to step up the Impeller speed.
They have fallen out of favor to the newer gear drive centrifugal blowers people use today.
The kits cost about $5000+ back in the late 80's, now you can't give one away.
I do have a water/alky injection system and have an upgraded impeller and cooling system (gear oil) for the blower.
Puts out about 8 or 9 pounds of boost on the mild ZZ4 engine I have, and is all emission legal in my TaxAchusetts.
All that work for about 400 rear wheel horsepower, and low 12's @ 119 -120 mph in the quarter mile.
Lot of cars come stock with more power than that now, but back in the late 80's early 90's it was pretty quick.
