Brian,

I use: http://vexer.com/68rt/speed.html to look at rpm vs speed vs diff and tranny ratios

With 25 in tires and 4.10 rear and no trans, at 8000 rpm you will be doin' 150mph!

Play with this calculator and adjust ratios and tire sizes. This will help in deciding which diff ratio will work best.

After playing with this a lot, I came to the conclusion that a 2-speed is the only way to go.

Personally, I am going with a powerglide tranny: 1.82:1 low and 1.00:1 high gear to solve my problems.

Anyway, have fun and I will be watching this one too.

How about a Ford Fairmont? Its light, RWD, Four doors, and Mustang Gt stuff bolts right up...like the excellent 8.8 LSD rear end and beefier front suspension. Lots of room (big trunk!) too....you can probably score a decent one for $500...

How do you plan to mount the motor to the axle? It had better be stout because the motor will be unsprung and moving with the axle. It won't take much of a bump to put tremendous loads on your mount. You will also be introducing a torque force into the axle which must be resisted by the leaf springs.

With direct drive you have to compromise between decent top speed and decent acceleration, if you go in the middle, you may end up with neither.

Why not go with automatic tranny? It works great for me.....

As for battery, you will get about 50 miles range at 80% DoD with this config. Is that what you expected?

It will be a very interesting build though, good luck....

P.S. My only concern with used AC motor/controller is lack of warranty. What if something happens to the controller? Also, I heard these are older models and may have some issues with regen.

40-50 miles is all we are expecting,, also I would like to mount the motor directly to the rear end no no drive shaft, that surley will help efficiencies, trying to chop weight and eliminate gear reductions etc. 80 mph is estimated top speed and I am hoping for enough torque for starts. Still planning ..nothing is in stone yet. Thanks for the advice.

Interesting SPAM, and as I've already pointed out the AT1200 won't work with the AC55, in case anyone is confused.

Hi Brian,
I am glad you like it so far.
Just so everyone is aware, these were all purchased in a bankruptcy sale that we found. We started with 30. We only have 19 more of these and then they are all gone at this price. So this is really a limited time offer. When they are gone, they are gone.

Most of them were never used, they just sat on the pallets in a warehouse. The most that any were used is 800 miles.

Rich Rudman at Manzanita Micro has one running in his shop. It practically walked across the floor when it throttled up.

Well thanks for chiming in glad to see your keeping an eye on this,, this motor is going to be just awesome,, these motors were desighned around runninf 5000- 11,000 pound busses so I can't imagine a 3500 pound car being much of a challenge for it.

Again thanks guys!!!!!!!

well today was power wash day and get er up in the air to its new position for awhile. It cleaned up nicely and went in the garage much easier this time with just me and the wife pushing it. It sure lost some weight,, I would have to guess 1200-1500 pounds lighter. Any way cleaned the shop then went to my favorite store "Metal by the Foot" they have it all. I picked up some "U" channel and angle iron,, now just to figure out how to get it all in the right place. Still figuring out how me alone will bench press this motor into place. Any way this is a mid day up date.

More to come later tonight (if I get anything actually done)

Brian
