By far the weirdest swap thought of. Anyways heres the Specs from Dragtimes,
“Car was converted to electric in 2005. Weight is 3250 lbs. It has 25 marine batteries (1000 lbs) a 2000 amp motor controller and two 9” diameter DC motors running directly into the differential (no tranny). Gtech Pro data shows 190 HP and 650 ft-lbs torque. This car ran a 14.27 at 95 mph for its first time ever on the track with street tires and stock open differential. This current record is with drag radials and limited slip differential. It is one of the few electric cars that have broken 100 mph in the quarter mile (see www.nedra.com)."
Very happy to see someone finally doing this with an S13. Electric conversions are already very popular with VW’s, and I personaly know of two such conversions in the GTA area.
One chap uses his converted Golf for his daily commute in the summer months only.
imagin running a 13 at the track with no sound at all other then a buzzing noise, when people do come and surround your car and are like “WTF” and you open your hood id loveto see the looks on their faces. more like where the hell is the motor?! i wounder if he filled in his gas tank door.
that is awseom! where is the electric cars that are gunna break the 10’s
I wonder how come they didn’t eliminate the diff all together, and have each motor directly driving each wheel. I am thinking it wouldn’t be too hard to simulate a limited slip by comparing the rpm’s between each motor and reducing the voltage to one of them if it is spinning faster.
Maybe they would have run into problems with clearance and mounting them out back like that, and it is probably just simpler all around to mount them in the tunnel. Would be cool for future versions though.
That would add a lot of complicated electronics to the car. He is using an AC drive which is very common in electric drag cars, as well as what OEM’s are developing. These are typically 200-300 volts, hence the need for the big battery bank resulting in the increased weight. The increased gear reduction from the rear diff helps increase the torque to the wheels, even though AC drives have excellent low RPM power.
I don’t think the electronics would be that much more complicated, but I did overlook the extra gear reduction. Of course they are using AC. DC would be less complicated electronically, but nowhere near as good as AC.
Since these electric motors have a shafts on both ends, I wonder how fast a stock 240sx with an Electric motor adapted between the differential and the transmission would be. The engine probably won’t need any tuning because it would be like Wide open throttle going down a steep hill.
