Good morning and thanks for the welcome!
I appreciate the chance to answer questions, and I will do my best to answer them as quick as possible.
JRP3 is correct about components availability. At this stage, Curtis went with the 550A at 144V because of the fact that currently
they do not have a MOSFET that can produce the higher amperage at the 144V level. But if you look at how things have progressed with the development of anything electrical, I would believe that we would see improvements over time.
In response to wanting the sup 12 second car, I understand the need, we all want to go fast, but remember that there are so many variables to how an EV will react off the line. Battery conditions, surrounding environment (cold or hot), weight of the vehicle, gear ratios, the condition of the drivetrain. Any EV will give you different responses based on the surrounding temperature. Take a vehicle to a cold weather state and it would drive differently compared to let's say Arizona.
Currently, we have converted a Scion Xb (which is on our website, unsolicited plug
)which has been driven over 2000 miles since the conversion. This vehicle is one of our test beds. This vehicle after conversion sits at 3400 lbs curb weight! It has the AC 51 motor installed with the 144V controller, and I can tell you from experience that it moves butt. I talked to Brian this morning about trap times, and he is going to program a stop trap bit for the Scion so that we can give out some data on time based on speed, but again, it is based on a whole bunch of surrounding conditions so your experience might be different then what we would publish.
What we sell is reliability, but also driveability. We have had many customers and vendors come by and mentioned that after they drove the vehicle that they did not know that it was electric.
Remember, we are building our own motor dyno for which we will be characterizing all of our motors that we sell. We will be updating our website and social media with updates on the status of this project, so stay tuned.
As an additional thought, the "AC-75" is still in developmental stage. We have a lot of work that needs to be done to characterize this motor. As we move forward, we will have a better feel for what this motor will be capable of, but again, it is still in developmental stage. Stay tuned!
Thanks for your time and have a great day,
