Hi Everyone,
I'm scoping out an EV 33 Hot Rod for a challenge, and just to learn something new from IC engine builds I've done before. In general I'm planning to use a transverse motor in the rear with batteries up front. It's definitely doable in theory but motor feasibility is proving difficult to work out due to lack of available details about the IRS geometry. I've contacted FFR for input but they're very busy and not sure when they'll be able to have an engineer look at the options I proposed - and they don't provide CAD models of course. I'm confident I can do the design myself but without the actual car yet or CAD files I've hit a wall. I've searched hours for every image I can find that might allow for some rough scaling but I haven't found enough info to do what I need. A friend has a MK4 Roadster under build that I've been able to get up under which helped, but it's different enough from the 33 to still limit progress.
I have plenty of time still but I need to make a decision whether to go with IRS or not before they start the production in a few months. I have a fallback option of using a complete Model 3 rear subframe with suspension but I'd prefer to leverage the FFR IRS setup. I was wondering if anyone out there has a Gen2 33 with IRS under build that would be so kind to take some detailed images with scaling features so I could piece together a CAD model close enough for doing feasibility checks. Or even better but less likely I'm sure, have one I could come check out. I'm in the Sacramento CA area.
If anyone is willing/able to help I can provide more details later.
Thanks!!
Brad.
