Great thread, thanks for all the updates. First thing I look for during my morning coffee break.
I'm glad you're enjoying the conversion and I apologise for the lack of updates, I'm busy moving house :cry:

A conversion kit for the Bay Window Bus will be available later in the year... many of the parts will be useful on a Split Bus 8)

Finally found some time to fit the CSF Drag Race Radiators. Next step is to add another panel to seal up the cooling air chamber 8)

The open source inverter controller tuning continues in preparation for a track day with Damien Maguire's BMW next week (here).

Yesterday we pushed the 'standard' version of the Large Tesla motor to 300kW traction and 125kW regen which is 110% of the power delivered in a Tesla Model S 8)

My bet that we can hit 800HP in the 'performance' version of the Large Tesla motor is looking good :D

Getting back to work on the bus and next we'll be installing a rear caliper with integrated electric parking brake 😎

For anyone who's interested, I understand this will be a future build option for the Red 9 IRS system :D

Loving what your doing with the electric conversion. :cheers: 8)
But one of the major things that suck about new cars is electric handbrakes. A friend of mine works for a well know insurance company and says that they actually add a premium to vehicles fitted with electric handbrakes as they are known to cause a huge number of claims.
I believe part of the problem is that when they are applied to hot brakes they don’t account for the shrinking during cooling and you end up rolling into someone while parked.
And anyway was it really that hard to pull the hand brake? :P

For the last 10 years or so most of my cars (petrol and electric) have used automatic parking brakes and I've not had any problems. Maybe it was an issue with the first generation cars?

One advantage of the electric parking brake is that you can integrate it with the motor control system (preventing the bus from moving when connected to the charge cable for example). It also allows me to get rid of the final cable control system in the bus :D

We've decided to rework the cooling system so that we can fit the larger SPAL fans. We will also add a bleed point to the top of the radiators to help with air removal :idea:

Started work on integrating the Open Vehicles Monitoring System (here) that will give us remote monitoring and control of the bus from a smartphone 8)

We're about to start testing the Tesla motor mount from Zero EV (here). This will provide a bolt on upgrade for any bus that uses the Red 9 IRS :D

Note in the background you can see the calipers with electric parking brake 8)

Apologies for the lack of updates... I've recently moved house and been in Romania working on an electric car for a new rally series (see photo) 8)

We've prototyped the rack that supports the battery modules and I should have some photo's from that next week. We've also resolved some issues in the open source motor controller and battery management system. I still hope to have the bus on the road this year ready for some long trips across mainland Europe next year :D
