I can't believe I've been into EVs for years, but have only just found this forum! Loads of good discussions & info...
Anyway, a bit of introduction is in order:
I'm Richard Bebbington, I'm an electronics/mechanical design engineer working for a design house here the UK and am in the middle of converting my old Toyota Supra Turbo to electric power!
The engine's already out, a Zilla Z2K is on order from CafeElectric (got my order in just in time!) and a big bad Netgain Warp11 motor is sitting in my garage...
There are several reasons I'm doing the Supra (besides the fact that there's one sitting on my driveway)
- It's a strong, comfortable car, great to drive
- The electronic systems don't talk to each other with CANbus or anything like that, so it'll be easier to make them play ball with the new electric powertrain
- There's tons of room in the engine bay for stuff!
Ok, some more details:
I've already mocked up the Warp11, and it just fits in, in fact the Supra looks like it could have been designed to take it. I should be able to get 14, maybe 15 Exide Maxxima's / Optimas in the engine bay (maybe more if I lose the aircon stuff), and probably 9 batteries in the trunk, without losing the rear seats.
The adaptor plate is turning out to be pretty easy, the bellhousing is almost circular where it bolts to the engine block. A simple 1/2inch plate and a Taperlock coupling will be about it.
What is unusual is I'm using an automatic gearbox - and there's a good reason behind my madness:
- First, the Supra box is the best auto I've ever driven - really smooth but also tough as nails.
- It's electronically controlled, and the torque converter can be locked solid electronically as well, so you only have the hydraulic pump losses.
- Lastly, I have an aftermarket shifting computer, so I'll be able to tweak the shift tables to make better use of the electric motor's torque whilst keeping the revs up and the amps down.
Anyway, that's a brief summary of where I'm at right now - currently waiting to finish the adaptor plate, then I can start playing with the auto gearbox and get other stuff like battery boxes and the high-current cabling.
There are some photos up on evalbum.com
, and I'm just starting to cobble together a website
for the project but I'm in the middle of changing ISPs, so let's just say that's a bit low down on the priority list...
P.S. Some of you might remember me from the EVDL, and yes, I did have an electric Mini. I've since taken the electric stuff out of the Mini and sold it on, so now the Supra is gonna be my electric fix!
I'm open to suggestions about lithium/lead hybrid packs, but cash (or lack of it) might dictate lead for now...
