General Project Update

I have decided to go with the WarP 9 motor due to mainly the fact that it has a pilot bearing hole in it’s shaft. The power and efficiency ratings are not far enough off to matter to me. The price is also right making it very equivalent with the ADC 9 motor I have been recently looking at.

The T5 5 speed transmission I picked up for $50 is not a world class, which won’t really matter, but my max torque rating is 265 ft-lbs. I don’t think I’ll have more than that at 1000 amps anyway. I pulled the tag from the transmission, cleaned the rust off it, and found the numbers 1352-145. The transmission is from a 1985-86 s10 with a 2.5 4cyl or 2.8 6cyl. The gear ratios from 1 to 5 respectively are: 3.76, 2.18, 1.42, 1, 0.72.

With my Cougar IRS, I think I counted about 3 1/4 revolutions per wheel spin, so it should be the 3.27 ratio rear end. With those ratios, the following is the speed per gear that I pulled from http://www.f-body.org/gears/

This was about what I was looking for, I want to use the motor in its efficiency range for using different gears for different speeds. 1st gear for 25 to 35mph, 2nd gear for 45 to 55 mph, 3rd gear for 65mph, and 5th gear for 195mph. Ok, so maybe I won’t be going 195mph, most likely the car won’t go over 100mph because of motor/battery limitations.
