pretty cool build! looks like the batteries are going in the rear. curious what the overall weigh distribution will be in the end? can you maintain the original 50/50 balance? and will you end up heavier or lighter than the original?

Yup, batteries will be located in two rear compartments.

The balance will (hopefully) be somewhat uniform. However, I have strategically placed a majority of the weight directly over the rear axle. I will work on the balance once I finish it.

Man I just typed a huge response to this and then I pressed backspace, and Chrome seeked back in history and all my work was gone :(

Anyway, round 2

Power is determined by voltage and amperage in the electric world.

The battery pack will consist of 416 cells with 4 cells in parallel and 104 in series. Each cell has a nominal potential difference of 3.3v.

Therefore, the voltage of the traction pack = 104 * 3.3

V Pack= 343.2v

Current is determined by both the batteries as well as the controllers. The batteries are 20ah A123 systems pouch cells that I bought from china Posted Image. 4 parallel = 80ah units.

Each cell has a discharge multiplier of 20-30c, therefore each battery module (8 modules) should put out 1600-2400A.

However, my controller has a limit of 2000A, so this is the system bottleneck. It can put out 2000A as long as you can keep it cool (liquid cooling).

P = I * V
P = 2000 * 343.2
P= 686400 w ----> 686.4 Kw

1 Kw = 1.341 hp

686.4 * 1.341 = 920 hp

Assume an 85% drive train efficiency

920 * .85 = 782 hp

On top of that, the motors can put out 1500 ft-lbs of torque at 0 rpm

So overall, the car has a potential of 700ish hp. I am assuming I will end up getting anywhere from 550-650 at the wheels.

It should be fun Posted Image



Once its done Ive got something to race it against / compare to.
Ironically, the car that it shall race was also the vehicle that transported the S2000's motors

Can you guess what it is ? :--)

The batteries will be A123 20Ah prismatic cells.

Posted Image
These cells will be arranged into 8 modules, with 52 cells each. The cells will be combined using a 4p/104s pattern.
I finished building 1 of the 8 modules last weekend, but haven't put it into the car.
I wanted to have a test drive this weekend, but the drive shaft shop sent me a drive shaft that was 3" short than what I asked for like lol wat. How do you mess that up? However, they have agreed to fix it so we will see how this turns out.

anyway, pics!!

Edit: Here is the drive shaft I received. The workmanship is there, however it is significantly shorter than I ordered / would be considered usable.

i absolutely love the sound that 9k makes, but i'd probably trade for an electric version any day of the week.
