I also made a spacer to position the coupler the correct distance from the bearing on the electric motor. I found that a coupler for 1" copper pipe has a 1.125" ID which matches the motor shaft. This setup allows the clutch force (only ~400lb) to be transferred to the drive end bearing instead of the shaft. The clutch will hold the coupler in position from the other side, so all the set screw does is keeps the keyway from sliding out.

I was wondering how much the coupler cost (materials and machining). I'm considering doing the same and am trying to determine if making my own would be much cheaper than buying the coupler/adapter from Electro-automotive.

The motor shaft x flywheel coupler was $125 including material.

junk yard jesse,

i am bored at work and need some updates on you car hahaha!!!
we were talking about you the other day because we had to dig up the bike pkg studies in Togo from way back in the day.
your cube is still empty but I think lou tericic is going to take your place.
i also stole your "this cubicle is so f'n small" sticker.

I have another project with a solid deadline so the electric car is on hold. I am building a car for the 24 Hours of Lemons race down here. It happens to be another BMW. Race is May 22 and the car still doesn't run, needs a new head. Started the cage work this week and hopefully will get everything back together and running next week.

It has been a while, but I'm finally back to work on my EV. I've been working on the engine bay battery brackets and mounting electrical components.




I also decided to mount the pot box on the firewall.


For charging I got a Netgain 3000W PFC off ebay. I think it is the same as the Elcon charger.

Love the build! I'm starting to plan a '77 / '74 MGB buildup and this is a good model. Thanks for posting all the pictures and details!

Awesome to see another E30 LeMons racer building an EV. We race an E30 on the West Coast (just won Buttonwillow in it, going to Infineon next week) and I'm building a 1965 Porsche 912 EV.

I'm following this build because of course, the E30 is probably one of the best chassis to ever come out of that era.

Thanks for the link. Thats good racing. Where did the mustang come from? Looked a little out of place.

Here is where our lemons car stands now after 3 races.

Awesome PBR E30!!!!

Nice. I attached a pic of ours. That was last year's theme. We have a whole new theme for this year, but I can't show it until it debuts at Sears Point.

We now have an Arduino controlled Air Brake like the one on the Bugatti Veyron. Is there any racing that is more fun than LeMons? EV LeMons...?

I've been doing some more work. Here are the pics.

Controller mounted


Installed motor mounts made from 3" diameter delrin bar stock.


Painted the front battery bracket

I've been putting some time into the electric car the last couple weeks. I installed a NEMA L6-20 plug behind the fuel tank door for the charger. I got a Netgain 3000W (rebranded Elcon) on Ebay and installed it in the trunk. Charging will primarily be done from a 240V supply. I installed the trunk battery bracket and threw some batteries in. They still need wired up. I also finished the brackets that will hold 4 batteries where the gas tank was.
