Scion tC Supercharger Kits
From SCION-TECH : The Scion Resource : tC, xA, xB, xD
Currently there is only one supercharger kit for the Scion tC made by Toyota Racing Development (TRD). The good part about this is it may be installed as a dealer option when you purchase your Scion tC Car. However, Toyota stipulates that it may not be financed along with the vehicle (check with your Scion Dealer).

[edit] TRD Supercharger Kit
Manufacuture:Toyota Racing Development (TRD)
Part Number: PTR01-21050-90 (2005-2006), PTR41-21070 (2007)
Pricing: $2,800 (2005-2006), $3,200 (2007)
Fits: Scion tC with manual transmission only (fit kit available for automatic tC's)
The supercharger TRD designed for the Scion tC is a centrifugal type. The centrifugal design uses a compressor that is similar to a turbocharger except that it is driven directly by the engine instead of by exhaust gas like a turbocharger. It offers smooth power delivery that is very compatible with the tC drivetrain. In addition it allows a compact layout that makes the best use of available space in the tC engine compartment.
The supercharger is belt-driven by the same serpentine belt that drives the other engine accessories. The belt drive is connected to the supercharger by a special enclosed shaft assembly that runs across the front of the engine. In operation the supercharger produces about 7 lbs. of boost, which is fed through the tC throttle body into the existing inlet manifold. A by-pass valve then recalculates excess boost back into the supercharger inlet when the throttle is shut.
An improved air inlet and filter system is included with the supercharger kit to provide the low restriction and increased volume needed by the supercharger while maintaining the evaporative loss capability required to meet emission requirements.

[edit] Fuel System
Larger 400cc fuel injectors are included to deliver the extra fuel needed without requiring increased the fuel pressure. No other modifications to the fuel system are required. Premium 91 octane fuel is required.
[edit] Engine Controls
For maximum power, good drivability, and to maintain emission compliance with supercharger, the original tC Engine Control Unit (ECU) needs to be reprogrammed. To accomplish this, a single-use “reflash” program is included with each supercharger kit. NOTE: A reflash ECU adaptor tool (Toyota Part # 00602-17620) is required to install the reflash program. The required reusable service tool is sold separately.
[edit] Warranty
The TRD tC Supercharger is warranted for 12-month/12,000 mile or the balance of the new car powertrain 5 year/60,000 warranty, whichever is greater, when installed by a Scion or Toyota Dealer. Installations by anyone other than a Toyota or Scion Dealer are covered by a 12 month 12,000 mile parts replacement only warranty.
[edit] Important Information
The tC Supercharger is an aftermarket accessory and has aftermarket emission certification. Because of that there are some important restrictions you should be aware of shown below.
The tC Spercharger System is to sold/purchased only as a dealer installed or over-the-counter option, after the initial retail sale of the vehicle. The supercharger may not be sold/purchased at the same time as the new vehicle and may not be financed together with the new vehicle.
