I think some people are not getting it,
This is a quote taken out of the article...
"Cohn and his colleagues have created a design that they believe could triple the power of a test engine, an advance that could allow automakers to convert small engines designed for economy cars into muscular engines with more than enough power for SUVs or sports cars. By extracting better performance from smaller, more efficient engines, the technology could lead to vehicles whose fuel economy rivals that of hybrids, which use both an electric motor and a gasoline engine. And that fuel efficiency could come at a fraction of the cost"
Now to me that sound like a bloody good idea.
Remember we are talking about direct injection and not throttle body injection with the use of ethanol.
Now is put the question out, can this be done to a throttle body injection were simular results can be achieved, 2x or more power out put with unbelievable fuel economy.
