Supercharger Identification

Supercharger Identification
All PSI Screw Supercharger have a 3 digit number that identify the rotor diameter in millimeters 200MM ,206MM ,210MM
210C Supercharger 


​206D Supercharger



​200H (highspeed)Supercharger
(no longer in production, rotors can not be replaced!) 

 
​
​200C (cast) Supercharger
(no longer in production, rotors can not be replaced!) 
This  is  the  original  PSI  screw  blower  pre  1991  due  to  the  cast  male  rotor  (see right picture with smooth balance plug) this model can NOT be SFI  certified 


Short shaft VS Long shaft rotors and housings
All 200 series superchargers are short shaft rotors and housings.

 206 series superchargers came in both long and short shaft configurations 


All 206B's are short shafts (both highspeed rotors and billet rotors were produce, highspeed rotors no longer availible)

206D models were originally short shaft rotors (single front bearing),
Long shaft rotors were later developed and continued using the "D" housing (dual front bearings) 
The 206D (long shaft) is still in production today 
 
​

All 210 series superchargers are long shaft rotors and housings
Picture
Short shaft rotors have a single front bearing and long shaft rotors have two front bearings

Both the 206B and the 206D (long shaft) use the same gears, drive flange, and quillshaft
Picture
206D (short shaft) housing and gears
The short shaft 206D uses a unique drive flange, longer quillshaft. ( gears no longer produced)
