Hi
I´m a street rodder from Sweden in northern Europe. I´m converting my 1947 Ford Business Coupe to EV by puting in Tesla components. I have a small driveunit with subframe that will replace the rear axle and my plan is to get a batterypack from a Model 3 LR and place it low in the chassis. I will have to split the battrypack in smaler sections to fit it in to the car.
The build is a three year plan and the criteries ar as follows:
Rear wheel drive
Around 300 whp
Limited slip differential (Burnouts are important!
:D
)
Batteripack in chassis
Supercharging with at least 50kW
Range around 600 miles fully charged.

Any input on this build will be appreciated!

That's a tough battery module packaging challenge, especially with the enormous Model 3 modules. You might want to check out SuperfastMatt's Jaguar Mk V project in YouTube, which is essentially the same swap into a similar chassis.

That's all relatively doable - until you get to 600 miles range
That will require the complete battery packs out of at least THREE Model 3 LR's - which will kill your performance

Do you NEED that much range?? - remember you will be eating at least twice as much power as a Model 3 just driving along the road

I assume that the intention was DC charging from Tesla's Supercharger stations. As has been often discussed, that is unlikely to work with salvaged Tesla components.
By "Supercharging", I don't think you meant "Supercharging™", correct?

^ C'mon Duncan...that was back in the heyday of "streamlining". If he keeps the weight down, he could do better than a '3 around town.
Its more streamlined than my Device - but so is a brick flying sideways

Sorry, did a misscalculation from km to miles! :rolleyes:
My aim in 400km range and that would be somewhere around 250miles.

Even that will be quite a stretch! - range is the most expensive part of an EV
- my car is very unaerodynamic so I need 130 kg of battery to take me 50 km at 100 kph
Your car will be larger but more aerodynamic so lets say they cancel out - 400 km will mean (roughly) 1040 kg of battery weight

Its worth sitting down and doing an analysis of the miles (km) that you actually drive
When I did that I found that 50 km was fine for most days - BUT when I needed more I needed 150 km
So I decided on the shorter range and lower weight (and greater performance)

Teslas do the 250 miles - and make it look easy - but it isn't easy!

Agreed. It's painful to tell people you're targeting 100-130 miles of range in your sports car build. Weight means crappy performance on all fronts....for a car.

The truck, however, needs in excess of 150kWh for hauling/towing for 150-200 miles of laden range, optimistically, so a tonne of batteries is in the chassis before your 45kg mistress sits in it. Then you get windbags like Musk bragging about 0-60 with a semi when all a truck guy cares about is getting up Vail Pass without smoking the clutch and doing more than 30mph in the climb.

I also get tremendous heartburn with ICE clowns demanding 1000 miles of range they expect from "next generation batteries" before they'll buy electric...no...the car should get lighter. Pissing in a bottle to drive without stopping is a bit mentally ill.
