Below are Notes of this Supercharger I have gathered from http://mr2.com/TEXT/SuperChargerInfo.html

It was an article supposedly posted on their old site and summarizes what was known in the 1990s. Now in the 2010’s many of this information may or may not be relevant apart from the blower and its nitty gritty specifications, use this as archival purposes and for anyone looking for more information. 🙂

The Toyota SC14 is compact heavy roots type positive displacement supercharger which can fit almost any car, it has the ability to spin both ways and still make power, A nifty feature these chargers also incorporate is a magnetic clutch system that when wired to a switch lets you turn it on and off when you desire, turn the supercharger on and off at will – akin to the Mad Max films, Some people wire it to the throttle position sensor, only having it on at full throttle, some also delete the clutch system altogether.

Originally Manufactured by Ogura Clutch, Code Named TX15 and more commonly known as the Toyota SC14 supercharger, many of its smaller and larger variants were used in Volvos, VW, Mitsubishi, Kawasaki Jet Skis, Toyota People Mover Vans, Speed Boats and many more throughout the last two decades. From AMR300, to AMR500, to SC12 and the larger sized SC20 and SC28 (Code Named TX20 & TX28), there are many of these blowers floating around for dime a dozen, and that’s what they are worth, while larger variations are still somewhat new and less readily available, this whole concept takes the SC14 or TX15 into account with possibility of future incorporation of other larger roots type blowers in its family as well as non roots, twin screw type eatons. Although The Roots is less efficient than the Screw Type Eaton’s, the SC14 is still a very robust and inexpensive charger which has displacement of around 1460cc which is relatively larger than the 1000cc Eaton M62 and more similar to Eaton M90’s which have nearly the same displacement at 1500cc. In stock the Supercharger can produce just under 5 PSI of Boost with its 113mm pulley with the option of smaller OEM or Aftermarket Pulleys as those from Pulleybros, Custom machined to make more power.
