Turbo or supercharger kit for the yaris availability?

Rotrex superchargers don't heatsoak like roots or centrifugal blowers because of the $100/quart viscosity fluid they use with the planetary gears to turn and produce boost versus the mechanical rotors or gears on roots/centrifugal which are friction driven and the Rotrex don't produce any heat compared to the other forms of forced induction. Rotrex actually don't even need a bypass or blow off valve because they don't get compressor surge like the other two styles. An intercooler on a Rotrex just means loss of 1-2 psi depending on the size of the intercooler and not as an immediate throttle response.

The only other type of supercharging that works in that way is a Comprex Wave Supercharger, but they can't take heat, so are not used in anything other than diesels.

Turbos obviously are the worse offenders of heatsoak, but that's obvious.
