So... it begins (finally)


Let me tell you a little bit about me, what is going on here, a little bit of history, and what I hope to accomplish with this project and this blog.  I hope you enjoy it and welcome any feedback, questions, and suggestions.

My lovely (and very supportive of me in this crazy endeavour) wife, 12 year old Rottweiler cross "Teddy" and I currently live in North Vancouver, BC, Canada and I have always lived within about a 25 mile radius from here for about 50 years, and then some.  Not far from home, I own a small company in the systems software business, and from my office I could watch the Olympic flame burning away in downtown Vancouver for the 2010 Olympic Games, and could also hear downtown Vancouver's "Oh Canada" air horns go off whenever "our team" won the gold (which was actually quite often).  I love this town.

It's interesting how I stumbled across the idea to do this project.  Two seemingly unrelated viewing events converged:
    http://www.whokilledtheelectriccar.com/1) I watched "Who Killed the Electric Car" when it came out several years ago, back in the mid 2000's.  I was completely impressed and amazed at how viable electric vehicles were, and the many benefits that they offered. I was impressed at how efficient they were, how they ran cleanly and quietly, and the film's message stayed with me for years.

    http://www.streetfire.net/video/a-car-is-born-episode-1_704503.htm2) I watched "A Car is Born" about 2 years ago now.  I'm not sure if any of you out there are familiar with it, but an employee of mine who was originally from the UK recommended I watched the series, and I was completely hooked.  Here's some countryside veterinarian who could barely change his own oil, using the most beat up and basic hand tools, creating this beautiful AC Cobra in his small shack of a garage.  The end result was nothing short of amazing.


    After viewing the latter, I decided that "If he can do it..." and that it would be a great way to use that third bay of our garage, currently filled up with a clutter of tools, compressors, gardening equipment, and other various junk.  I then began my research, Googling about Cobra kit cars, and I somehow stumbled upon this "eCobra" and couple guys in a poorly produced video series talking about how they were attempting to power it with an electric motor and lithium batteries, etc.

    It completely blew my mind.  The twain met.  Electric cars + Electric sports car. Actually cars, plural, after also seeing the bevy of Porsche Speedsters that the pair had also converted. Wow.  My potential pet project just became an obsessive mission.

    A mission indeed. I pored over every EVTV blog entry, watched every video, read entry after entry on DIYElectricCar forum, and had bought a quite few books on the subject.  I was soaking up information like a sponge, and while there was a lot of information out there, it was clear that this was a field in its infancy.  A field that seemed to suddenly become a real-world practical option due to the fact that lithium ion batteries that would work in an electric vehicle were finally becoming a reality, in size, availability, performance, and reliability.

    I then started thinking about the best "roller" (i.e. electric conversion candidate vehicle), and then that became yet another obsession.  After weighing everything, needs (light weight, easy to work on, seats wife + dog) vs wants (classic, sporty, mid-life-crisis mobile), I decided on a late 80's Porsche 911.

    One from 1987-1989 to be exact, to get the strong Getrag G50 transmission that was available in those model years, and still be in that "Classic 911" lineage.   I thought it was very important to have the strongest transmission available, since the torque on these electric motors are incredible.  I don't want to lose anybody here, but for electric motors, maximum torque is at 0 RPM and holds there roughly out to 4000-5000 RPM (or more) before it starts to drop off, unlike gas engines where the torque ramps up in near linear fashion from 0 ft-lbs of torque at 0 RPM, up to maximum torque out at 5000-6000 RPM, give or take.

    So… while the header of this blog serves as a nice spoiler, you can imagine where I ended up.  More on my "roller" next time.

    In the meantime, let the fun begin!  I'm pumped.

      1. Welcome Joey! I guess it is about time for you to be able to sit back and watch someone else's adventures in converting one of these classic 911s. Your comments, tips, tricks and critiques will be more than welcome!
