No useful info to provide but I'm curious to know more about your MK2, do you have a build thread that I could peruse?

 

[seatosummit]

Hey @fakename -

I didn't do the original build. I bought it about a year ago and have been slowly upgrading it.

It has Enerdel 8 8s4p modules (~15 kWh lithium) Orion BMS + curtis controller + warp 9.

I added J1772 charging and a lot of CAN functionality, as that is what I do for work.

The MK2 is in remarkably good shape for its age, save the suspension which is sagging due to the original lead weight.

Does anyone know if I can use the existing adapter plate and coupler from the GTI for the 914?

M guess is that there is approximately zero chance that the bell housing pattern for a Golf matches the old air-cooled VW/Porsche pattern.

I did a Google search for "vw golf bell housing pattern": the first page match is a discussion in VW Vortex about bell housing interchangeability for various transverse water-cooled engines and they don't even mention anything air-cooled.

While drawings for the air cooled VW/porsche adapter plates are relatively easy to find online, I am having trouble finding anything that is specific to my Golf.

In my Google search the images clearly show a typical modern automotive pattern, not the VW/Porsche air-cooled setup.

Imagine I will know as soon as I start pulling the ICE from the Porsche and the motor from the Golf, but would love to know from a planning perspective before hand.

Good idea.

Since the 914 does not use the axle shafts as part of the suspension, there is no mechanical need to stay with the original transaxle. Since the 914 has a big wide space available ahead of the axle line (to accommodate the mid-engine, and achieved with trailing suspension arms of unusual proportions), it might be possible to fit the engine Golf powertrain - motor and transaxle - in the 914. It would be strange, and might not fit, but it might have packaging advantages.

Awesome. Really appreciate your input on this.

The transmission in the VW has failing synchros on 2nd and likely should be rebuilt before too long, so I am hesitant to go that route.

In the case that I am unable to find a use unit, I am thinking of sourcing the adapter and coupler either through EV west or through electric motorsport.

Does anyone have experience with the unit from electric motorsport : PORSCHE Adapter Plate w/ Hub for WARP and HPEVS Electric Motors

Thanks @Russco -

It looks like that one doesn't include a coupler nor mounting hardware. Both solvable problems, but noteworthy.

I am going to see if Electric Motorsport has anything in San Leandro, as that would be easy for me to visit.

Still curious to hear peoples opinions on manufacturing quality from various vendors.

Cheers

Canadian EV (Randy) had a whole bunch of adapters for many makes of cars including your air cooled Porsche. But the company seems to have sold to another party in a different location in British Columbia. So, who knows?

ZEVA (Ian) in Australia has retired last year. There aren't many EV suppliers left.

With an old worn out VW bug crankshaft, and gland nut, a good machine shop will be able to make the motor shaft adapter. You will also need a VW or Porsche flywheel, pressure plate and clutch disc.

I've called around and it seems like EV vendors are suffering supply chain woes like other manufacturers.

Maybe be worth exporting the worm crankshaft route. Thanks, Russco.

Hi Austin,
I am converting a 914 and trying to get a CanadaEV adapter plate. My conversion will use the 901 transaxle and a HPEVS AC-50 motor. I have one recent quote from CanadaEV for $975 (part no. 5059) but the shaft adapter is not included. And I am seeking a quote from a U.S. Vendor (Electricmotorsport.com) for the entire CanadaEV kit but still awaiting word.
The project's design has veered from attempting a DIY adapter design to purchasing one. Consequently, I have an adapter plate design in a solid model if that is of any use to you. This was for a HPEVS AC-31 motor which I am not going to use.
Regards,
Bill

Hey @914EV

Yes! That would be of great use to me!

I was just about to fire up fusion 360 to draw out the transaxle, but I would love to use yours as a reference.

The HPEVS uses the same bolt pattern as the Warp, if I understand correctly.

I just contacted Richard at EV4U to see about sourcing coupler/adapter plate combo that he machines.

Good luck with your conversion, would love to see some photos!

Thanks for your help,

Austin

I'll be emailing you shortly.

I'll be emailing you shortly.

Thank you very much for the detailed drawings.

I am intending to pull the ICE from the 914 this weekend and will likely follow up with some info on what I find wrt flywheel status.

I've found a source for the coupler and adapter plate through EV4U in Northern California. Waiting to pull the trigger on purchasing until I can inspect the factory flywheel and determine if I can reuse it.

In the meantime, I have made really good progress on extracting the internals of the VW. Turns out it is an impulse, not a Warp.

Started to tame the rat's nest of BMS cell taps that the PO thought was a reasonable cable management scheme.

 

[seatosummit]

also learned the current transducer was never installed, which might explain the poor BMS SoC readings!

Guts of the new contactor box:

 

[914EV]

Really good progress. The contactor box has my attention. What is your thinking on using the breakers versus the bolt tab fuses I see used in some designs?

Thanks -

Excited to have something material to look at.

The din mount devices closest the contactor are actually fuse holders. I use them for PV installations at work and quite like the ease of installation and easy adaptation according to application. Simply pop a different fuse in, if you want to accommodate a different circuit (assuming, of course, your conductors can withstand).

Here is the link : Fuse Holder

Hopefully some good progress this weekend!

Just an FYI - The WarP 9 and ImPulse 9 usually have a different bolt pattern! The normal ImPulse 9 (there are 4-5 models) uses the 8" motor bolt pattern, there was an initial version (00-08249) that used the 9" bolt pattern. Best check against the drawings here to see what you have: Motor Information or send the serial number to info @ go-ev.com
