SPC 42v Alternator or Dual 12v-42v Alternator  Finally, the ULTIMATE in electric  supercharging! Introducing the new SPC  Thunderhead alternator series! These  amazingly compact Thunderhead 42v  dedicated alternators can be added to your  vehicle or using the dual 12v/42v model,  replace your current alternator entirely.  A matched  dedicated model comes standard  with our superchargers.  The dual voltage is  optional for those who wish to simply use the  stock location.  The 12v output is 120amps  standard and optionally more.  Too, we now  offer super high amperage single voltage 12  volt alternators up to 400amps.  Please  enquire for more info. Full Carbon Fiber and CF/Aluminum Matrix Compressor Wheels   Stronger than aluminum compressor wheels by far. The NEW CF wheels will reduce spool time even further,  provide higher rpm capabilities and drastically reduce weight by as much as 70% when compared to a normal aluminium compressor wheel!  We expect final models to be completed by Fall 2011.
