Is there an easy way of increasing power of early model V8 Soarers?
There is no easy way of extracting extra hp from the V8 engine besides a “free-flow” exhaust system that may yield about 10 kW extra at the wheels at the possible cost of increased noise, vibrations etc. Extensive testing showed that replacing the OEM air-filter element does not bring any power increase. Later model Lexus SC400 V8 engine has VVTi (variable valve timing) and 280 hp.
