I was aware of the Dutchman IRS, but at the time I was looking at having the pinion point towards the rear of the car. Currie is local to me and they offered to swap the fill and drain plugs because the rear end was to be mounted upside down. The original plan was to put the motor and trans in the rear and balance the car by putting all my batteries (CALBs at the time) in the front. That's all out the window. The final plan calls for the motor and trans up front with all the batteries in back (A123's)

just sent you a PM Dan

Currently we don't have much data on a standard unmodified warp11hv...

It would be really nice to see what peak power rpm figures it could achieve with the right battery/controller combo..

ya, I mentioned that to him. . . but, I was wrong.
He could have gotten better performance with the higher torque of the Warp11 I think.

I spent hours upon hours compiling research from the EVTV blogs/videos and many more on this forum, as well as studying heavily all info in could find on John Metric's "DC Plasma" and John Wayland's "White Zombie". Even then I wasn't satisfied, so I figured I should just call up NetGain and see what they had to say.
I ended up speaking with George himself. I asked him a ton of questions and he was more than generous with his time (Thanks George). We talked about different motor and controller options, gearing and probably a hundred other variables. I hung up the phone with a solid understanding of his product and what it is capable of within it's recommend limits.
This was great, however a new problem had surfaced. For those not familier with the Porsche 944, it has a transaxle, meaning the transmission is combined in one unit with the differential at the rear of the car. That by itself is a good thing, it actually gave the factory car almost perfect weight distribution. Alas though my 944 was born without a turbo so the tranny and diff are somewhat weaker than the turbo version. I needed to find a diff to handle the torque of the 11hv and the correct gear ratios to run. After a bit more research and a few calls to some petrol-headed friends I had my answers.
Out here in So. Cal there is company that does a lot differentials for 4x4 and hotrods called Currie; they make a ford 9" just like the "Zombie" but this one is independent so can retain the factory rear suspension. Differential problem solved - a bare 9" IRS housing that I could mount in place of the factory transaxle.
Now for the 'transmission'. The 11hv would develop enough torque at lower RPMs, but how to keep it in the power band for road driving? - Enter the Gear Vendors overdrive. With a 1:1 'first' gear and a .78 'second' feeding into a 4.86 rear end I was reasonably sure this is was a good solution. After one last look at the dyno curves from Jacks cobra I called EV Source (NetGain distributor and maker of the warpdrive controllers) and placed my order.

Disclaimer: non of this has been tested, not yet anyway, it's all just figures on paper.

I should have the proof in a few weeks once I drop the motor in.
I really should start a build log, but I'm not much one for documentation. I will surely though report my results once the car is off its jack stands and back on the road.

Once we're both done we'll have to compare results. I'm using the 11HV in a 944 with a stock turbo transmission (car was an '86 NA but the first owner put in a turbo tranny.... not sure why). I'm using a Soliton1 and small A123 pack (317V, 56Ah) I won't be removing any extra weight though, I enjoy the car with full interior etc so the finished weight should be around 2800-2900lbs.

Thats pretty damn light...

and I look forward to the results of your testing!

[Dustin_mud]

Currie makes some very nice parts, we like to use there 9s front and rear in crawlers. Can wait to see what you come up with.

Its good to see you in here RW, I have been secretly admiring your progress for some time now. I'm constantly checking http://electricporsche.ca/ for updates. I too would love to compare data when I have some.

I don't want to hijack this thread, so it's about time I started a build log. Maybe later tonight but I need to see if there is a way to recover my 'lost' iphone pictures from my cloud account, the ones of the motor mated to the trans.

Figured I should post a picture of the motor since I have it in my warehouse. The dollar on top is or scale.
My motor is a TransWarp 11HV. It has the larger spline output shaft which is the same as the GM Turbo400 transmission and was build and shipped in late February 2012.
If it weren't so cumbersome I would hoist it up and bolt on my Gear Vendors and take some more shots. Guess we'll all just have to wait a week or two before I get to that.

Edit: Can't seem to get the picture to post, so here's a link: http://www.infaspace.com/gallery/944-e/

Thanks onegreenev. I see the pic when I view your post from my phone, but not from my desktop machine. Can't quite figure that one out.

[onegreenev]

Workin on that.

Done
