Ev conversions just got a LOT cheaper. One of the biggest hurdles was the motor and inverter assembly. The are open source controllers now for many toyota hybrid inverters which allow them to operate most 3phase motors. Additionally he has an open source inverter kit that you can build from a...

Better shot of the drive unit

Hello. Saw this thread and thought some of you may like to see what we did with a P85D rear drive unit...

We still have some finish work to do, we fabricated a battery/electronics cover today.

Greetings all, Newbie here. I'd like to introduce you to the 911 RSR racer that myself and partner Lee Phillips are almost done building for Telefunken Motorsports

We are ready to start tuning our P85D rear drive unit installed in the 86 Porsche RSR Racer. It has been a great project and should be a lot of fun to take around the track seeing as though it has gobs more power than any Porsche engine ever put to a 911 chassis.

This is a picture from a few months ago before we powdercoated the carrier.

Sorry, dont know what happened...

The tesla series is having problems. The tesla batteries are no good for racing, I hear they are derating in less that 10 laps.

Great article!

We have been considering doing a motorhome for quite some time

You mean a race car like this?

I have thought about doing a motorhome with rooftop solar. It sure would be fun to camp for a week or two to charge the battery up, travel to the next campground...

Yes, there is a solod supply of motors from salvaged Teslas. The motor market is emerging. WARP just started offering a relatively powerful ac motor, rimac has an excellent driveline, but it seems like Porsche has sunken their teeth into Rimac.

As for tesla GT, it is failing from what I understand. The tesla batteries cannot handle the abuse.

It has been a while, I've been very busy with this project, 80s era RSR 911 Porsche Lime Rock Park racer. We just did our first test spin up of the tesla motor at 180volts, hit 15,000 RPM on the lift. #P85DPorsche.

Yes, EV west has a system that you have to send your motor controller PCB to them for them to reflash, and then you need their $4k controller. They have been working on a cradle for installing the tesla motor in a 911. They have been working on it for 6 months, and still have issues with it. It...

Also, there are better (NEW) batteries than used tesla modules. Not everyone has room for 900lbs of tesla batteries, and not many have the skills to rework them for proper battery management, which is really the most important part of a modern EV build, it controls power flow, charging, cell...

Using tesla drives gives you weight below the axle centerline, and allows you to use space formerly occupied by an engine and transmission for batteries.

When considering the cost of all involved with a proper conversion, using the tesla drive units is a VERY cost competitive way to build a car, front drives are cheap, lots of rear drives available too (I have a source). They offer a compact package that won't destroy an OEM transmission or...

Im talking to a friend who builds them, tube frame rock crawlers is a great application for electric, to use a tesla drive, you'd have to mount it centrally and essentially use it as a transfer case, and for control of torque, you may have to use additional gear reduction.

Im not building cars for people to get groceries with. Yes, about 25k to convert a car with cheap components and a small pack is about right. We are designing a kit car meant for racing on a porsche platform. Nich market yes, but the focus will be in building the racing team, garage and making...

There are many other motors available, land no transaxles or transmissions that can handle the torque. We will be scanning all the axle parts for the intent of manufacturing heavy duty replacement of gearsets and cases, final drive options and compatability with other motor technologies. Tesla...

Gross, just gross. I see standing for 5 minutes in sub-freezing temperatures outside in freezing rain or sleet to put fuel in a car as an "unstoppable barrier" which are rediculous words put together in the first place.

We are starting with tesla parts, Damien's control boards and some high tech racing cells that are smaller, lighter and have a much better C-rate than tesla batteries. We just picked up a p85d driveline and will be ordering boards this week. Every tesla component we use will be disassembled and...

We just picked up a p85d driveline and will be ordering boards from Damien at evbmw for a former porsche race car. Im ordering a completed board and a bare board to build for each charger, front and rear motor drives.

It is mainly the drive units I'm after, they are more power dense except for maybe remy motors, which GM uses in their 2 mode hybrids, but they need the reinheart controllers which are very expensive.

I have a guy with a bunch of porsches that wants to convert a daily and a racer.

My last conversion was a VW cabrio with a 26kwh pack and AC motor. Driving that electric convertible was one of the best driving experiences I have ever had, it does 95 with the top down, and about 100 mile range if you are really nice to it, and its much faster than it ever was with the 2 liter...

Yep. See that, pre coffee eyes....as I said new here and exploring.

No shops on the east coast, I closed mine in CT from lack of interest, but am looking at doing tesla conversions, so this thread is interesting to me for sure coming from a classic car background.

I am working with some partners to develop tesla conversions, it's early, but we have the right people to make it happen, even talking about developing improvements on stock tesla components. I'm relatively new here, trying to educate myself on the brand and the issues that require technology or...

I'd like a section on conversions as well, new here, but comversions is what I do.
