I just read about an electronic typhoon supercharger that adds 10 to 20 horsepower. I know 10 to 20 horses isn't a lot but anything can help me out on the bottom end of my white 2000 Celica Gt-s. Does anyone know if this would be a good investment for 150.00? Has anyone ever purchased the supercharger? Here is the link i found the supercharger at
