Yep, regen works wit the AC motors...actually diesels (trains) are moving towards AC vs. DC because of the improved efficiency at more than just one set RPM, and also because you can't really over-rev them.
THANK YOU!!!! I found reference to that previously but could not for the life of me find anything on it again. Plus it would be kind of cool to break out the old non-power boxes for these thingsYeller wrote: ↑Wed Dec 07, 2022 5:23 pm Electric power steering is easy, use a manual box and a power unit from a Prius or from flaming river steering.

It's because unlike a gasoline engine, an electric motor uses less power at higher RPMs (I read somewhere that most AC motors have a sweetspot around 8-12k RPMs), so the older underdrive transmissions allow you to get it in that sweet spot for most speeds. They don't make much power in those RPM bands but they don't use much either.SJohn wrote: ↑Wed Dec 07, 2022 10:14 pm What purpose does the 3/4 speed transmission serve in the EV driveline. Instant torque from the electric motors negate the need for a lower gear and can provide the power/RPM for highway speeds but I could see a 2 speed or overdrive unit for trying to squeeze out some efficiency. In my mind it seems like adding a traditional transmission in an ev driveline is mostly excess weight. I know Porsche has developed a 2 speed gearbox for improving top speed and efficiency at those high speeds. Other than that, sounds great. I would love to do an EV conversion as well but battery energy density and prices aren't where I'd like them to be yet.

So I should still plan on putting the Ford box on is what I'm hearing (the pitman arm goes opposite to how it goes on the Saginaw boxes, so I can move it back on the frame and run however long of a pitman arm I want, to get more steering out of it...and with the later front axle there are lots of clearance issues with the stock steering box). That's good 'cause I already have oneYeller wrote: ↑Wed Dec 07, 2022 8:58 pmYour welcome!sierrablue wrote: ↑Wed Dec 07, 2022 5:42 pmTHANK YOU!!!!

You can use a power box for better ratios, you just have bleed out about 1/4 of the fluid in the box and connect the ports with a hose. The old manual boxes are great but the ratios suck. That power unit with a nice 3 turn box would be the bomb.
I'm not sure on the angle exactly, but it has noticeably less steering even than my dad's truck ('74 F100, D44 front), which is made up for in a shorter wheelbase, but still irritating. When I went to adjust the stops on the axles (a PO had bigger tires on it at one point so I thought maybe they weren't adjusted right), I put it on where the wheel stopped and there was still 1" between the stop and the axle--the box was out of travel.Yeller wrote: ↑Thu Dec 08, 2022 10:28 am Just curious, how much steering are you trying to get? My J truck is a 70, I have upgraded to thew newer open knuckle front axle. I used the correct pitman arm for the newer truck, it is a bolt on, and get as much steering as my axle shafts and ujoints will allow without binding. The limiting factor in steering angle is not the steering box, pitman arm or knuckles, but the clearance within the axle shafts. That being said I have modified Dana 60 front axles to accept 50 degrees of steering successfully, and even larger 1550 ujoint equipped axles to 60 degrees. I do not believe there is enough meat in a D44 axle to get that same amount of angle. Dana 44's are typically limited to 38* +/-. The newer axles like in the JL and new Glad's have a larger ujoint, allowing for more angle. I've done a lot chasing steering angle in competition rock crawling.
Thank you Stuka!Stuka wrote: ↑Thu Dec 08, 2022 4:50 pm TFL (youtube channel) partnered with a company that does after market swaps. Not that you need to do a Tesla swap like this, and having a shop do it like they did here was pricy. You can probably do it yourself for less than half the cost.
The truck had a very worn out for i6, that was needing to be rebuilt/replaced anyway.
They did the swap in a similar manner to what you are suggesting. The motor is connected to the transfer case, so it retains the 4wd and everything.
A coworker of mine actually did an EV conversion to a Honda S2000. He actually kept the 6sp manual trans, as the motor he used (to save costs) didn't have the RPM range to forego the transmission. So he drove and shifted it as if it was a gas engine.
Personally, I think its great for something you drive to work every day, or cruise on the weekends. The reliability factor alone makes an EV conversion very interesting.

Maybe, but you also put out the anti-offensive rules and such (those over on IFSJA may have seen my issues w/advertising beliefs that have absolutely nothing to do with Jeeps). You make the rules clear and participate in discussion, gaining even more respect (well mine anyway).Stuka wrote: ↑Thu Dec 08, 2022 8:30 pmsierrablue wrote: ↑Thu Dec 08, 2022 6:02 pm Thank you Stuka!
