Re: Hot rod EV - looking for advice.

it is easy enough to shorten half-shafts its the frame mounting points are the hard part to move but not impossible As a hot rodder it's really very easy, we're used to fabrication like this. In the coming weeks I'm going to have the subframe and suspension 3D scanned so I can build an accurate mod...

Re: Building a new Chassis/Skateboard

Where are you located? I had Brisbane in my head for some reason. If so Doctor Tim comes highly recommended and is experienced with all sorts of vehicles. Perhaps ring, make a time to see him and offer to pay for that time. They will show commitment from your side and guarantee his attention. https:...

Re: Hot rod EV - looking for advice.

Can you just use it at the same track width (Wide track is always cool), I'd even say its easier to stretch a body than it is to narrow a drive train. In a nutshell, no. The Model S is 1964mm wide, my pickup is 1928mm wide. While that's only 36mm, the Telsa also has no wheel offset which looks terr...

Re: Hot rod EV - looking for advice.

It has me excited for the project again. It helps not only having a supportive wife, but also some really supportive work colleagues (including mechanical engineers offering to do FEA on components I need to fabricate).

It may not be common, but the rules and legislation already exist to accommodate it. I know this as a fact.

Re: Building a new Chassis/Skateboard

It is black and white, you just haven't found the right people to talk to. I understand you've gone to the right people, but they are clearly clueless (or to be fair to the, under-trained).

Re: Hot rod EV - looking for advice.

Just the real subframe, brake to brake. I couldn't justify having a drive unit sitting around for X-number of years before I needed it. I have a known-accurate 3D model, I'll build one out of wood for setup. It came out of a write-off in Sydney, 2014 (MY15) dual-motor Model S. Someone posted the Gum...

So after some reading through all the stuff on NCOP, QCOP, etc it looks to me that an easier way to do a conversion would be to potentially: 1) Pick a Body on Chassis donor 2) Replace t...

The 19 mm hole made for a slightly sloppy fit (0.1 mm radius too large) but unfortunately 18.8 mm drills are not common.
Why wouldn't you get it profile (laser or water-jet) cut?

I may try a set of Koni adjustable or Frequency Selective Dampers in the rear in due course.
I would highly recommending talking to MCA Suspension if you decide to change anything. They are absolute guru's and will develop something vehicle specific.

Re: Francisco's Electric Pajero

Regarding the spacers between the front diff and drive shafts, I wonder what an engineer will say about that? Wheel spacers are illegal for on-road vehicles due to the additional load on the wheel studs. I can imagine a similar "longer lever" issue with this diff arrangement. Certainly a wheel depar...

Re: Hot rod EV - looking for advice.

I had some time to play with the 3D model this arvo. I question its accuracy, it seems maybe 5% out, but as a proof of intent it's sound. I grabbed the mounts off the subframe (purple) and moved them inboard to (a) see if it clears the drive unit and (b) determine if the mounts can still be picked u...

Re: Hot rod EV - looking for advice.

I found a CAD model of a Tesla Model S chassis, I can't speak to its accuracy but the geometry looks about right. Based on this I think it would be possible to narrow the track while maintaining the stock suspension geometry. This is really exciting, I like the idea of using the Tesla power unit, th...

Re: Hot rod EV - looking for advice.

Perhaps a fair comparison between vehicles/motors is to look at the torque curve rather than the power curve. This is what I was getting at, power not really a useful comparative tool for EV to ICE. ( Jason @ EE's video is really handy about this. ) To answer the power and performance question, I w...

Re: Hot rod EV - looking for advice.

Francisco, thank you, everything there is very helpful. I too will be running independent rear, the simplicity of running a splined coupling in place of a tail shaft will be a big advantage for packaging. I hadn't thought of that. Adverse Effects, the Tesla drive unit would be the ultimate, but the ...

Did you have a target kW? Nope, no idea, and no real clue on how to calculate it either. Because of the torque curve I'm guessing power is less of an issue for EV's? Any tips?

Thanks for the information, it's starting to paint a picture.

I'm fortunate enough to wor...

Re: Hot rod EV - looking for advice.

I'm actually comfortable leaving the motor and batteries further into the build. It is body-on-chassis construction, this offers a number of advantages in strength, packaging flexibility and weight handling. The wheelbase is fixed, as is the cabin, which defines the position of the front sheetmetal....

Hot rod EV - looking for advice.

Hi all, new member here. I'm about to start building a 1951 Ford F1 pickup truck , imported from Oregon, USA. I had planned to use a Holden / Chev LS-series motor, but the lure of EV is strong, especially after seeing this at SEMA . The fabrication is the easy bit for me, but I know next to nothing ...
