After a lot of advice from this board and others I've decided that the endplay on the output flanges can be ignored for now. So..... Let's get this baby back on the road!!!!!! (IMG:style_emoticons/default/aktion035.gif)

Here is the B.F.N. tranny mated to the motor. Yep, that's it. Hook two big fat wires to this thing and it goes! No F'n' ignition, valves, carbs, oil, cams, exhaust, etc.....

The future is here for the b'stards with money. The Li-ion batteries look really good right now. Crazy energy density. My car would end up lighter than it was as an ICE and get about 300 miles/tank. The cost is scary however. Multiple tens of kilo bucks. (IMG:style_emoticons/default/blink.gif)

I guess the other cool stuff is what does an electric car really need? (Save wieght sort of thing). No more gas tank, fuel lines, exhaust. I guess you would have to live w/o a heater. All in all, I would imagine your 914 probably wieghs about 2300lbs with it's current set up? Just a wild guess though.

This is a cool thread. (IMG:style_emoticons/default/biggrin.gif)

It's even more dramatic with some newer cars. No radiator, water pump, emissions crap, the list goes on an on...

What has been an interesting topic of late on the EVDL is what to do about the new computers. So much of the stuff is driven by that little computer. If you remove the engine and emissions stuff the computer will think you have serious problems and may or may not drive the all electronic dash! No signal from the fuel injection and you may not have a tach as a side effect. Hell the air bags might just decide to randomly fire just out of spite!

I 'borrowed' a lot of the existing 914 wiring to save on running new wires around. That's no so easy with the newer cars.

I'll let you know about the weight in a couple of days when I'm on the road. I'm going to drive it over to the scales to get it weighed. Also going to put it on a dyno to have a look at the torque. It won't be pretty but I'd just like to know where I ended up. Otmar has got some scary 800 ft-lbs or something but mine will be pretty close to a yugo-ish. (IMG:style_emoticons/default/laugh.gif)

This rocks! (IMG:style_emoticons/default/mueba.gif) Can you post a pic of the 914 when it is back on the ground?

What guages are you using to monitor the battery pack? (IMG:style_emoticons/default/idea.gif)

Do you have a regenerative braking system? Are you familiar with Xstatic's 800 BatCap? I'm not sure if it would offer any weight savings, but, the product looks interesting, faster charge and discharge rate, your thoughts? Do you qualify for the federal tax credit, or is that only for buying an EV? Are there any state incentives? And, what's up with 3M? They got 60mil in grants in the '90s, and were promising delivery of EV lithium batteries by the year 2000. Also, have you been able to find any pricing on SAFT's VL 45 E module? How many would you need to replace your batteries? I wish I had gone to EVS-20 last year in Long Beach, EVS-21 is in Monaco. A little too far. (IMG:style_emoticons/default/blink.gif)

Amps going back in after a short spin around the block. Number on the DVM is charging volts (140.9) at the moment. Only 8 amps since it was only a short spin.

This is a shot of the alternate alternator. Basically, it converts the 120V battery pack to 12V to charge the little system battery. It's actually somewhere around 13.8V just like an alternator.

These are a couple of relays to keep the car from operating while it's on charge.

Motor and controller. The box to the right is the controller. Essentially it's what regulates the current to the motor based on the throttle input.

In the center of the picture is the contactor. It's a big fat relay that closes when you step on the pedal. You can hear it slap from pretty far away. Also shown is the second shunt that allows one of my guages to measure the current leaving the batteries and also returning to the batteries when on charge.

This is the one item on the outside of the car that always catches the eye of someone who knows 914s. (IMG:style_emoticons/default/laugh.gif)
