Here's my 1975 911 widebody, currently has a 3.3 twin-plug motor with a 915 trans with LSD, it could get up and scoot. The blue pic is what it looks like now, after 4 years of work, and the red pic is what it looked like when I bought it 4 years ago.
I know I want to use a Tesla Drive unit, and I know I want at least 150 to 225 or so miles range, and I think I need the capability to quick-charge on road trips at around 100 miles ranger per hour of charge. I'm needing to know what kind of rectifier/controller/BMS/charge connector I'm going to need.

Any input you may have would be wonderful to hear, as this is how I learn best.


PS: Anyone know where I can sell a motor and trans?

 

[Mick_D]

Yes, in conversation with Michael already. I have a parts list but it's incomplete ( no drive axles or motor mounts,for example) and his conversions are designed for Level 1 , or at most 7.7khw charging. It's where I'm starting, though.

Didn't convert a cab to a coupe; the landau top was fake. It was the work of about 2 hours to peel it off with the help of some Goo-Gone Pro Power and a wide thin putty knife. I was shocked to find no rust under the canvas.


I was hoping to use the LG Chem battery set, if I can configure it for around 48kwh. Ultimately, I'd like to be able to plug in at home for overnight and do a quick-charge on the road, if I have a 250 mile range in a sub-3000lb car. If you've got any better ideas, I am all ears, as my only current investment is a book that hasn't gotten here yet

 

[Mick_D]

That was kind of my philosophy too.

I'm looking at these, and doing the thing he mentions in the blurb for the extra kw.

If I can get 225+ miles per charge, and charge for an hour or an hour and a half for another 125 or so, then I think I could get from Dallas to Rogers AR in around 6-7 hours rhather than a 225 mile drive, an overnight stop somewhere that has an overnight charging station or somewhere I can plug into, and the remainder of the drive the next day.


Ultimately, though, this is a 'nice-to-have', and if I don't have it on initial conversion, I will be ok as long as eventually I can upgrade to it.

What's the reasoning behind those batteries?

The main reason is that of all the 911 widebodies running a Tesla drive unit and controller, I have not seen any running Leaf batteries. I have seen Tesla, Chevy Volt ( which I think are LG Chem) and LG Chem.

Hello Mick

I was wondering where you would have the space to fit all those batteries for such a range in a 911?

Cheers,
Remi.

Oh, heck if I know, Remi. I can put them anywhere they'd fit- over the motor in the back, in the back seat, up front where th4e gas tank used to be, glove box, under the dash, in the passenger seat ( dog would have to sit on the floor but oh well )....
