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.....

How many batteries will fit in this thing?

Are you going to use solid bus bars to connect the batteries together? Any figures on how much it costs/mile to charge them? How many miles do you figure you get before having to replace all those batteries? Curious about the numbers.

hey bob91403 try the electro automotive web site. They sell a 914 specific conversion kit and they have some samples and general info about the running costs of an electric.

What he said.... Electro Auto is a great company. By the way, I suggested the 914club be put on his links list. It's right at the top!

Bob - I'm not going to use solid bus bars to connect the batteries. Basically for vibration reasons you want the connections as flexible as possible. I have connectors made out of sheet copper. They can take the amps (500amps or so) but are fairly flexible.

As for cost it's about $2-$3 for a full tank. And a full tank gets me from anywhere between 50-100 miles. It don't pay for any of it though since I charge at work. (IMG:style_emoticons/default/aktion035.gif)

YMMV but I expect to get between 15-20,000 miles out of this pack.

I have considered doing an electric build. Are you using electro autos Voltsporsche kit or are you free handing it? (IMG:style_emoticons/default/assimilate.gif)

A little of both. I started with their kit. Great stuff! Very well thought out and quite detailed. Anybody that can swing a hammer and miss their thumbs could do it. As I went along I thought of improvements so I upgraded this and that and modified some things. They are great to deal with but don't bother emailing them. I don't think they operate the computer much. Phone calls are the way to go. It took me 3 months of working a little at a time after work. One of the motor heads on this board could probably do it in a weekend. (IMG:style_emoticons/default/cool.gif)

If I ever get hit in the head by a sack of money, I'm going to upgrade the batteries. There is another list I belong to called the EVDL. We've been following the latest battery developments. If you have the money then there are some real scary battery alternatives. Right now it's only the insane wealthy that can do it but that will change. There is a couple of people on the list that have put in Lithium ion batteries. We're all waiting to hear the long term results.

oh and I see you're down in Florida. There were a few people on the EVDL that were powering their homes from their electric cars during the recent high winds you experienced. (IMG:style_emoticons/default/unsure.gif)

One step forward and about 10 steps back.... (IMG:style_emoticons/default/mad.gif)

First, one step forward... motor and tranny ready to go in

... and 10 steps back...

The only thing different this time is the 911 sport mounts. I measured them before the switch and they were only a few thousandths smaller. Where I had about a cm of clearance before now I have none.

Wiskey Tango Foxtrot ... Over?

So it looks like I'll have to move my battery boxes up. (IMG:style_emoticons/default/mad.gif)

Hmmm that's about 24 bolts (2 boxes), a bunch of sealant, and I gotta fab a bunch of spacers... (IMG:style_emoticons/default/mad.gif)


Not the least of which, I will lose my ability to put the top in the trunk. I know this is a family website but FUCK FUCK FUCK FUCKING FUCK!!!!!!! (IMG:style_emoticons/default/ar15.gif)

Can't you just space the tranny mount lower to get the clearance? Worth a try before you raise the battery box.

That's a great idea for the long term. Thanks for the suggestion.

Short term I have about $1000 in batteries sitting on my garage floor that have to get in there and on charge before they die.

I'll have to fab a nice block of aluminum like you have in your pic. I've got to drop the tranny about 1.5 to 2 cm. Perhaps for just today I can add about that much in washers to the 8mm bolts on the tranny mounts. (IMG:style_emoticons/default/idea.gif)

Will you still have a clutch? Will shifting be normal?
Pretty damn neat.

Yep, clutch is stock. Shifting is normal I just don't do it that often. I like 2nd around town and 3rd on the freeway. (4th if one of you bastards are trying to pass... (IMG:style_emoticons/default/lol2.gif) )

And you, Mr. Evil, are quickly coming up on my list of people to contact. Once this transmission nastiness is behind me, the interior will be needing some work: Dash (or dash pad), seats, etc....

Ok, so I've been laying under the car staring at the situation. I can't just add a bunch of washers to lower the tranny mounts. The darn things are angled so if I lowered them the bolts won't line up. But it's small enough that the new hole would overlap the hole to mount the spacer to the car. Is any of this making sense?

Anyone remember their high school geometry? Anyone have a suggestion?

Any thoughts on hybridising? Could you put a honda generator in and reduce the volume of batteries? Trying to keep the range the same, reduce the weight, and have an on board charge source. Could you use the smaller battery supply for around town driving, and turn the generator on only when you needed the extended range? Most trips are not 100 miles. I realize the generator could not keep up with the draw rate. But, there should be a mid-point, battery volume vs. battery volume & generator, that would show an advantage. Are those glass mat batteries?
