Have you had the chance to charge the battery pack completely? Also, have you done any hard pulls to provide feed back on how it accelerates? If you did do WOT pulls, do you find certain gears to not be as useful for maximum acceleration or its still worth going through 1,2,3 etc...

Car has 20 miles on the odometer and is configured for 40% power. I will increase available power by 10% every 50-70 miles. I'm itching to do a full power pull as well, but as many of the powertrain components are new and/or untested, I want to proceed carefully. I expect to do a full power pull after the vehicle has +500 miles on it. I'm currently charging the battery to 97%.

Next build goals

Currently, the EVO has 35 miles on it and road testing is FINALLY in full swing I have decided to prioritize some late-stage objectives by mileage. I intend to stick to this schedule and I also expect to diverge from it almost immediately

At 100 miles:
- Install and mount J1772 charge port in fuel door
- Wire J1772 charge port to charger and charge module
- Purchase J1772 charge cable (for home charging)
- Conduct the first charge at a public EV charge station
- Measure vehicle curb weight

At 200 miles:
- Bump motor power to 70%

At 300 miles:
- Design gas tank battery compartment for 72 additional cells (bump pack voltage to 344v)
- Bump motor power to 80%

At 400 miles:
- Build prototype gas tank battery compartment
- Contract fabricator to make a professionally welded lightweight version of my prototype
- Send off BMS to be reprogrammed for extra cells
- Purchase accessory materials to add extra cells to pack (fuse, fuse holder, cell heaters, 2/0 cables, accessory wiring, wiring protection, individual cell taps, etc)
- Bump motor power to 90%

At 500 miles:
- Bump power to 100%
- Inspect gear oil

Before 1000 miles:
- Install gas tank battery compartment
- Wire new cells to BMS
- Wire new pack to existing trunk pack in series for 344 volts
- Reconfigure motor controller for 344 volts
- Street test

Beyond the 1000 mile mark (next summer):
- Install 640kW motor controller and a second 9" DC motor, make 600wtq, blow up transmission, melt LEAF battery pack?
OR!
- Completely replace DC motor setup with salvaged Tesla motor, inverter, and open source controller hack for 10,000 rpm powerband and regen capability?

I think you need to get a wrecked Model S P100D and swap that over next!

What's with the window tint fee on the paperwork? They charge you extra for having window tint on your vehicle in your state?

I'd love to swap a P100D heart into the EVO, but it's beyond my present budget due to the ever growing market for used Tesla parts.

In my state, sedans are not allowed to have tint with a translucence rating lower than 35%.
I believe that, if the inspector notices your car is tinted, then the tint must be measured. For that, they charge you.
Also interesting to note, my registration expense now includes an annual electric vehicle fee of $130. Yay.

Lol. They can't get your money from fuel taxes so they tack on an extra fee. Seems legit.

Is it because of people doing hotrod things like you, or people repairing Teslas, or?

That's interesting.

Look forward to seeing more updates here. Glad you are able to find some time to work on it now!

Daily Driver Duty

The Evo is a legitimate daily driver now. I plan to order all of the J1772 parts this weekend and I'll soon be able to charge in the EV parking spot.

150 Mile Update
I've done a few things over the last 100 miles. Gear box and T-case oil change. Readjusted the rear suspension. Replaced the hood vent fins with a plexi glass rain guard.
Bumped power up to 50% around the 100 mile mark and the torque increase was very noticable. Bumped it up to 55% this past weekend and sensed that even a 5% increase was perceptible. I will be ordering the parts for J1772 charge capability this weekend.

I posted a video about a year ago when I conducted the very first road test. I hope to upload a new video once I install the J1772 charge components and bump the power up to 60-70%.
