dghii Too cool!! Congrats!

Can't wait to hear more about driving impressions and battery performance (range, charge time).

This is my first experience with a non-production electric car, but I can safely say the driving dynamics are vastly improved over the orginal. The motor makes no vibrations, so it is very smooth running down the road. The power is also greatly improved. The Hyper 9 motor makes roughly 120 hp and 170 ft/lbs of torque. It is not gratuitously fast like a Tesla, but certainly quicker than a stock spider. Because of the torque curve, you can start off in third gear, but 2nd seems to be the best combo for zipping around town. I have not ventured out on the freeway, but it pulls quickly to 60 mph.

The thing that takes most getting used to is the lack of sound and the clutch. The motor doesn't need to idle, so to pull away from a dead stop, you put it in gear and press the accelerator, no clutch slipping. You can also row through the gears and it behaves just like a gas engine. Out of habit, I always press the clutch when stopping, but there is no need in the electric car. The car makes a futuristic motor sound that is somewhat pleasant but no substitute for an Alfa engine. You can hear the gearbox and drivetrain noise, which fortunately is tame in this car. The downside to all of this is the 40 year-old car squeaks and rattles which now take center stage with no engine noise to mask it. Once you go above 45 mph, it's all wind noise.

All and all, I am happy with the performance. Next up, reassembling the interior...
A video is demanded by your loyal fan club...
...when you get time!

otteud96 I am sure that alfas always overachieve leak oil regardless if they have an engine or not....

AngloSpider Great thread and awesome work. I like the attention to detail in your work practice, too, like the rubber gloves and plastic handled wrenches. I wouldn't have thought of that.

[email protected] I too have a 78Spider I'd like to convert. It's without an engine or transmission and was initially intended as a home for my Daily Drivers engine.
I'd love any help/direction anyone can provide.

Mousetrap I’d just like to say how much I’ve enjoyed this tread and what an inspiring project.

I can’t wait to hear how it drives.

The motor is actually mounted ahead of the center link, but the adaptor plate is about a 1/4" inch clearance at full lock. It looks pretty close to 3/4" with steering straight ahead. It is a little tight, but the motor mounts are significantly stiffer than the stock, so it won't be bouncing around.

Kim Boydell "thermal runaway" I like that, it sounds better than an uncontrolled fire
When I consulted to the air navigation industry (not a controller, more like a planner), I enjoyed all the euphemisms for major incidents (itself an euphemism) with aircraft. My favourites are:
"contained failure" - the engine blew up but all the shrapnel remained within the cowling;
"uncontained failure" - the engine blew up and the shrapnel blew through the engine cowling; and
"controlled flight into terrain" - the pilot crashed the plane.
There are many other.

Elmolino, your project looks fascinating and I am enjoying following it. It will be great to see how it runs when you are finished.
