    Has anyone used the Singh Groove on their heads? I'm thinking about trying it. Research says that it will give you a 20%HP increase, witch would put TW at about 20HP with stock setup. I know 4HP doesn't sound like much, but every little bit helps. It is also said to increase fuel milage anywhere from 10-42%. Let me know you thoughts.

    I am intrigued but skeptical.
    I wish the information was written in better english, most of the writings come off as gibberish. For an idea patented in 1999 there seems to be little follow-up documentation too. I would like to see some qualitative or quantitative endorsements from third parties however none of the supposedly substantiating links could work for me. "Five senses" seat of the pants testimonials from the author carry less weight than empirical data. Show me the results of all the significant time, energy and money that went into the research please before I embrace this "discovery".

    Edit: Subsequent searches have revealed positive subjective endorsements from third parties.
