I'm still planning to use four of the 8 x 15 wheels I have on my Birkinized Caterham. Doesn't sound improper to me. Edited May 25 by pethier

Elldawg Posted Saturday at 02:43 AM Posted Saturday at 02:43 AM It’s bittersweet, the car just got dropped off in Denver from CA. I’m here placing it in its new home a few weeks before we move in and it’s my only ride for the wknd so if you see an all yellow 7 tooling around Denver that’s me! I have nothing better to do but blat for a day. 5 1
theDreamer Posted yesterday at 02:08 AM Posted yesterday at 02:08 AM (edited) Today was the Boot ‘n Bonnet Club’s spring tour. It was not supposed to rain but it was only 7c when I left the house so the wife made me wait while she put up the hood. As she says it’s her job and I’ll only screw it up. I left it up all day. Although there were lots of clouds it was a high UV day and I have to protect my skin. Plus, it was better for the high speed Super Slab drive to and from the event. (About an hour and ten minutes one way.) We had 14 LBC's in total. We drove some very nice hilly, twisty roads well within the legal limits. (I will go back later in the year to re visit a couple of these roads and I will maintain a higher average speed. Edited yesterday at 01:28 PM by theDreamer 5

Caterham 1700 Super Sprint: The pushrod engine, cable-operated clutch, bellhousing, and Ford T9 5-speed has been removed. That drive package is slated to go in a USA7s member's Lotus 7. The Birkinazation process: Install drive package from a Birkin: Ford Zetec engine, larger clutch with hydraulic operation, alloy bellhousing, and Ford T-9 5-speed. Ford injection not used. Prior to my ownership, the Zetec ran side-draft Weber carbs, then Hayabusa injection. The Birkin that provided the driveline is now 100% electric.
Reiver Posted yesterday at 05:07 AM Posted yesterday at 05:07 AM Oh, ok, but they put Zetecs in Caterhams too so..... I am a fan of injection myself. Too many years fiddling with carbs...

pethier Posted yesterday at 05:10 AM Posted yesterday at 05:10 AM Pictures today? Well, I'm still awake. I need to sell this one.
pethier Posted yesterday at 05:15 AM Posted yesterday at 05:15 AM Just pulled this one out of my trailer fresh off the road from California. 2
pethier Posted yesterday at 08:05 AM Posted yesterday at 08:05 AM 2 hours ago, Austin David said: whoa -- details? i really don't have a lot of details. Steve wanted to make his Birkin an electric car. My only significant involvement in the project was to buy the gasoline stuff from the car. (in the process I found that it is possible to harm a Zetec engine from a Birkin in a Caterham in a way that was not possible when the engine was in the Birkin.) Steve's Birkin has a live axle, so one thing I can tell you is that Steve kept the driveshaft (propellor shaft, to our British friends) and has sited the electric motor in the front of the car. Steve has been working on this electric project for several years. The control system is highly-sophisticated. The object of the enterprise is autocross performance. Steve and fellow autocrosser Harold finally got the car to an autocross practice day just before I went to California. I have told Steve about USA7s. If he chooses to join us here you can ask him.
toldfield Posted 17 hours ago Posted 17 hours ago Why get down and lay on the garage floor when you can get your grandson to do it? Maybe he can clean up the garage next... 5
