sure i know that $$$ are a major fact but considering this tornado booster (if it would work) in a way as for example the variable intake tubing systems you find in a car, it nothing else than further engineering and development. intake systems today work with different tube lengths and ways based on throttle position. that was developed and implemeted in the past. and before they decided to implemet it, they did cost research, risk and changes, surveys and shit like that. now, if a tornado would work the impact could be the same as with those developments.
or vanos. someone invented them through development. so could the tornado be a new thing.
i agree with you in terms of brakes and lights and stuff, cause they work properly and they way they do work they are efficient enough to please the public taste. the tornado effects gaz consumption and that is point where the consumer is never satisfied. they always want less for money and environmental reasons, and that i believe makes this sector a high priority one.
of course, it would need calculations etc....but if it would work and looking how cheaply this tornado is (material and technical wise) automotive industry could see a valid improvement for a reasonable increase in price. as they don´t, the tornado does not work
