  1. It's a 6 liter V12 from a '96 XJ12. It's quite a behemoth but it fits every requirement I had: V12, suitable for use as a structural member, fairly robust, reasonable easy to find at a reasonable cost. It's over-square stock, which bodes well for making it rev if the valvetrain can keep up. I've also read that it isn't uncommon to bore & stroke these beasts all the way up to 8L.

    I've built a few autocross cars powered by CBR600 motors. They are ridiculously fast and a real blast to drive. This time around, I want something for use as a street car. The motorcycle engines just aren't big enough to push around a 2600lb car. Besides, as awesome as an inline-4 sounds when it's spinning at over 13k, I think a V12 sounds better at only 9k.

  2. I'm specifically wondering about MA, but I'd also like to know about other states. I need to know about emissions (what standard do I need to meet?) and chassis certification. In MA I need a certificate of origin, but what does that mean or entail, especially with regard to a chassis I designed and built myself?

    I bought an engine for this project a couple of days ago, so I've taken the essential first step towards this two-year project. I figure now is a good time to start looking into what it's going to take to register this beast.

    On the Canadian beers, I'll see your Maudite, and I'll raise you a "Fin du Monde." Something that tastes that good has to be good for you, right?

    If you like La Fin du Monde, I'd recommend giving the DogFish Head "Raison D'être" a try as well. Slightly lower alcohol content (8% vs 9%) but the taste has a similar character.

  4. I'm a fan of stout, although after a day of riding I often find myself with a few bottles of the Otter Creek Stovepipe Porter. I'm also a fan of all of the Unibroue brews (Raftman, Maudite, La Fin Du Monde, Eau Benite, etc). When I can get my hands on it, I also drink BHBC's Cadillac Mountain Stout.

    On a conventional board you become more aggressive with edging, balance, and pressure the faster you go. On an I.C.T. board with the same length, side cut, flex etc. you can use a more passive technique at the same speed.

    Carve radius is a function of board stiffness and sidecut, nothing else. (although actually, it's the stiffness that determines how you use the sidecut, but that's not the point). What matter is that damping is not the equation.

    All ICT does is convert some mechanical energy into some electrical energy. What this does is dampen the vibrations. All a damper does is resist velocity, not displacement (a spring resists displacement, not velocity). See how this does not affect carving technique on fresh cord? What it does do is allow you to be lazy in other snow, because the board will, to some degree, soak up more of the bumps than it otherwise would (a duty that is normally assigned to your legs). This still doesn't play into board angulation.

    Neuffy,

    There are a number of composite fibers which have been demonstrated to stiffen when current is applied, but very few which do the same for voltage. One thing about the piezo effect is that generally it is very high voltage with extremely low current. Of course, with a snowboard you have the potential to use some really big crystals, and on hard choppy snow there is quite a bit of energy to dissipate. The Head website claims that the board becomes stiffer *torsionally* as a result of ICT. This means they could use shorter "magic fibers" since they run across the board rather than along it, and they could even be concentrated in only the ends of the board where they'd make by far the most difference. That would leave you with a lot of crystal to power very little fiber.

    My guess is that there IS a chip in the board doing something, and that there IS a battery powering it. Typical watch battery lasts 5 years. With no high drain items to power like a backlight or LCD, the chip could be a bit more powerful than a watch and consume similar power. The chip wouldn't exactly be a power house, but that's ok since it doesn't need to be.

  6. Steve,

    There have been a few pretty big advances in piezo electronics in the past few years. The best specific application of them was in the shoes of endurance event participants, such as those in the Riad Galoi (sp?), Eco Challenge, etc. Small electronic devices can now be powered via crystals in their shoes. By small, I mean tiny - last I had heard, a digital watch was about the limit, although advanced items like GPS receivers were predicted "soon."

    Now, does Head say it works purely via the piezo effect? It's entirely possible that it uses some sort of magnetic induction.

  7. The bindings turned me into a short, fat, 40 year old, man with no job, no life, and a strong Lawnguyland accent.

    Actually, the bindings broke the topsheet. At the very least, I should have mounted them on a rubber gasket like with the TD2s. Revision1 will make use of UD fabric which should help a bit, too.
