So now that the rear mounts for the motors are done, and out to metal fab, I am coming back to look again at my front end sketches, and trying to fit a drive in up front. The issue is you need to open up a fairly large hole in the firewall to fit the drive through. On par with the size of the...

so, just a fyi, you probably already know this, the center spine of the chassis is offset i think 4 inches to the passenger side. swaping the from RHD to LHD is going to leave you with a pretty narrow drivers side. If your are really tiny you maybe ok. If you are a 6'3" "gentleman" you might...

Yeah so when I looked at the fusion360 output dxf files in adobe they looked fine to me. However the company I am using, ponoko, flagged them all as having double line weights. Basically the laser would cut everything twice is how they explained it. The same files on my friends cheapo Chinese...

I have a set of LG chem's, but I am going to use them on a different project, a pulse autocycle i picked up. Going with a custom battery here, kind of like alot of electric motorcycle guys are building. Trying to link up 4 strings of LG chems was just going to get to costly with battery...

Yeah it's not they way I have done it before either. But the clearances where so tight, the semi-symmetric design, and the with the number axis i had hit just made sense to try something new. Plus with 3d scans of the motors and chassis available it was a logical choice. The cost of laser...

Couple more shots of the subframe on the motors. I haven't removed the inverter from one of them yet, but I had to make sure I could get frames in to the units, and that everything was aligned. I need to add a couple access holes for nuts, but it looks ok. Going to cut a few parts more out...

MDF prototype came in. What a pain the workflow was. Fusion360 has a real issue exporting DXF files for laser cutting. Had to manually edit them in adobe for single cut lines. Real adventure. But, fits like a glove. A couple pieces need slight modifications, but I'm going to aluminium and...

so i'm talking about one of these https://www.carscoops.com/2020/06/1988-pulse-autocycle-is-an-aircraft-shaped-honda-goldwing-powered-oddity/ I bought a pretty abused one for low money. They are a really joke of a design from a frame standpoint, but the fiberglass is really cool. I am...

I'm in MA, right outside Boston. Just sent the subframe design out for MDF prototype. Here are some mockups of what went out. I really wanted to see what could be done with slot and tab design. The angle on the uprights was a real pain to work with, but I think I have the whole assembly to fit...

So I am running the inverters not attached to the drives. The inverters will be in the location I show in the photos, one inverter per side. Removing the inverters allows me run two drives in the rear, to center the mass perfectly over the rear axle line, and lower it in the chassis to an...

Short update. Pulled the inverters off the drives. No real issues, thankfully there are some videos of people doing it on youtube, helped to make sure I didn't miss any bolts. Oddly, there is not a "how to" video, but just click bait videos, "look's what inside a tesla!", but it helped to see...

Got the first part of the motor subframe designed. see the pictures below. I have been wanting to try out slot and tab fabrication techniques for some time. This seemed like a perfect application. The tolerances on the slots are .5 mm, and the parts went right together. Welding them up will...

I did not realize he was modifying the chassis for you. If so I can think alot of changes that would make it fit very well. It will be interesting to see what he does. If you get images please post them.

So the cooling problem with the large drive pushing "performance +" mode is not about cooling the transfer fluid, glycol/water, better. Guys are running ice boxes on their glycol loops for short races and measuring the temp rise as it passes through the motor, and still only get 2c changes in a...

Yeah I have had the car at my warehouse for a couple weeks now. It was dusty, but all there. Pretty much un-touched for 9 years, some surface scrapes on the front air dam, and on some of the body panels, but nothing major. I sat in it for the first time, and it is much more roomy than I...

Supercapacitors...ultarcapacitors....they are still aways away form being suitable for a primary drive ev, even in a hybrid capacitor/lithium pack. Just take up too much volume. If you custom designed a chassis with them built into the frame, maybe, but unlikely. They work ok as source for a...

You will fit 12 of the recommended lg chem batteries in the engine compartment with no issues, you can fit 6-8 in gas tank area, and 6 in the motor bay and really have a balanced lay out. It will have a lower center of mass that a ls. The Tesla drive is about 100 pounds heavier than a graz. You...

So this is something that we have talked alot about. The original plan was to do 2 small Tesla drives up front, but I just can't fit them in. The slc I have scans of at least has the center chassis rail off set to the passenger side. It makes fitting 2 drives very tough. The single large drive...

On the traction control. Tesla drives are all open diff, and they use a brake based traction control unit. There are open source inverter boards that can be installed into a Tesla invert and allow one total control over all parameters, some have used this to add indrive TC. However, much like...

At long last I can start a build log for this project. The idea has been building for just about two years now, serious planing for about a year. I went back and forth as to which platform to do this build on, the SLC or the Ultima. I was able to get very good scans of both chassis, and both...
