makes PLENTY of boost for any engine up to 500 cu in -  for Street or Marine use

Great Street sleeper blower to hide under the hood.  

Street engines on pump gas will have to have 9-1 compression or  less or use our Torco Octane booster to raise 93 octane to 103

Also Used in High Compression LS   Chevy Race cars to add 4-10  lbs of boost to equalize Atmospheric conditions when the air gets dirty, and/or  corrected elevation  and density altitude caused a negative impact on  your ET .

A 71 style Supercharger sticking out of the hood is always a nice addition, but it may not be what

 you are looking for.  With our 250 BilletCharger blower series we have solved that problem.

 Still producing the most boost in the industry these dangerously powerful blowers come in a beautifully small package. 

 Perfect for tight clearances and low profile under-the-hood applications.
