Shit, I ran an electric Mazda RX-7 in '96 that would run 12 second quarter miles. "Performance" is an area where electrics stomp the shit out of gas - you make peak torque at 0 RPM and a 500HP electric motor weighs about 130lbs.

The trick is endurance. Pike's Peak is the perfect race for an EV to show off. Thanks for sharing this.

    you make peak torque at 0 RPM and a 500HP electric motor weighs about 130lbs.

I'm curious. What was your setup? What batteries did you use, how much did they way, and where were they in the car? I know the batteries, especially if you go with lead, add enough extra weight to negate the lightness of the engine. The fact that you can put them where you want though really helps with controlling the weight distribution.

I gotta be honest. I think a 5th Gen El Camino would be perfect for an electric car. Right behind the seat is a compartment called "smuggler's box" and it would be the perfect spot to store the batteries. It's close to the center of the car which would help out with the weight distribution while still allowing you to use the bed.

Wasn't my build - I just interned that summer. As far as where the batteries were - EVERYWHERE.

Battery tech has improved since I was involved, but I'll bet you still need lotsa lotsa batteries. We built a Taurus using Optima yellowtops and we had 12 over the motor, 12 under the seats and 12 in the trunk.

Which was purely for range. If you just wanna haul ass you don't need a 3x144V setup, a 144V will do.

::Whistles:: A '68 Dodge Charger rear end. I'd have love to see how they managed to get that to fit an FB RX-7. That's almost as impressive as the electric conversion.

. . . I want it.

Cutting down live axles ain't no thang. I made a Ford 9" fit under a Triumph TR-7. Think the whole conversion cost me $250. All you gotta do is ship the housing and the axles off and they'll cut 'em down and respline 'em. Change out the bearings and you're good to go.

Ah. I never knew. Then again, I never changed out a rear-end either, so I learned something today. Thanks!
