Hey guys, I'm sure I'm kind of an oddball here.

I just turned 18, and am starting my degree in mechanical engineering next fall. My dream job is converting existing cars to have electric drivetrains.

My daily driver is a mostly stock '71 Jeep Wagoneer. It's BRIGHT blue (Sierra Blue is the official name), and I want to make it electric when I have the funds and know exactly how I want to do the conversion.

I'm not a huge fan of new cars or Tesla themselves, but I like the EV drivetrains.

I'll add my ideas and maybe some pictures of it soon, I'm on both the International Full Sized Jeep Association and the Full Sized Jeep Network forums, also under sierrablue. I'm excited to learn about these and see what other people are working on, and learn some more about the specifics of EV conversions.

Hello! Not an oddball at all, we're all learning! and saving 馃ぃ
Good luck with your studies
Thanks 馃槀

I'm also hoping that people on here will be a LITTLE different about things than the Full Sized Jeep guys. I have a lot of respect for them don't get me wrong, but they don't always understand. You ask about tires for a DD that mostly just sees pavement (which, around here, likely has snow on it at any given time for 6 months out of the year, and that could be any amount of snow from a dusting to about 10" at any given time), and they tell you you have to get all terrains because otherwise the sidewall will fall apart on even the simplest forest trail. I've had my all seasons on a forest trail, and they still hold air just fine...they're white walls, too.

I understand the mechanical aspect pretty well (not what to buy but how it works, and in general what's better and what's not), and am excited to figure out the electrical side of things. The big reason I'm not after electrical engineering is that it's so computer-oriented now, and I'm not really interested in building computers 馃し鈥嶁檪锔

EE concentrations can be much more EV focused. Power electronics is the specific field of study it sounds like you're looking for. Lots of volts, lots of amps, good stuff.

Every community has its die-hards, the folks on here are pretty tolerable though!
I am a 21 cs student and have been assembling a drivetrain over the last couple of months with my spare time and money. If you have any questions feel free to message me as there is so much information that understanding everything can be somewhat paralyzing. Good luck!
We try to keep the information out in the open on this forum, so everyone in future can benefit.

So unless you are trolling for a gay relationship with someone with common interests, I suggest you keep the exchange non PM.
Fair enough, I was just intimidated to post on the forums while I was starting and had 'simple' questions.
Thanks 馃槀

You have to understand the context and science, vs getting all snowflakey about it and going off your own data that's derived from a single-sample anecdote. If the collective wisdom is,"don't do it", it's part if an engineer's training to understand why they would say it as much, or more, than why they might be full of shiat.

You likely did not deflate all four to 6-8psi on that trail (which is why hard core offroaders use beadlock rims and offroad posers have beadlock-look street rims), which severely loads and heats the sidewalls on a street tire. You can have a high speed blowout on the highway after such sidewall abuse....which can kill you when a topheavy, lifted, 4x4 flips.
Flip side, PM means you don't have twelve other people jumping in with their opinions and answering questions that weren't what was asked...

I mean I never said I was a guy...I am, but I never said so. And I like girls, not that it's anybody's business or that it matters.

This is true, but based on what I've seen, FSJ guys aren't usually particularly big on engineering and WAY overbuild things, and tell everybody who doesn't that they're doing it wrong. Most of them are either mall crawlers or actual off roaders, so they assume everyone will run into the same issues they have with MASSIVE tires and whatnot. And they'll tell you it's not worth it to drive nicer and have simple things like locking hubs 馃檮. I have a lot of respect for all of their knowledge and their trucks, but their answers for my questions (or statements that are known to be true by well, physics) aren't always logical. And if nothing else, they're excited if they get 10 mpg and I'm mad that I'm getting 13 since I broke my Quadrajet carb that got 14-16.

Um, it's bone stock. It's like 65" tall, with most of the weight at like 16". Also, you're correct, I left it at 35-40 psi and even left the hubs unlocked--it's a basic forest trail, not an off-roading trail.

Honestly most of my off-roading is done on the mountain bike...the Jeep needs the 4x4 and ground clearance for the snow.

Thank you! I'll probably have lots of questions. Maybe you can program the Jeep for me while I get the mechanical aspect sorted 馃槈

Yeah, I know it can be, but the basic degree is more programing and computer-oriented, which while I can follow most of it, it's not particularly fun for me, and just not what I want to do.

Yep, I've noticed that. I'm super excited to get more involved in the project and learn all about how to do a conversion (the right way 馃槈).

Flip side, you're looking out for your own interests and not respecting expert time. Basically looking to get one on one consulting and handholding for free.

Take it to PM and do not read ANY other threads here, then and see how that works for you. This is not an introduction to experts site, not a one on one support line either - it's a knowledge repository

OK I have a lot of respect for what information you have, and this isn't an attack on what you know or anything like that. But in both of my threads, any time anybody says something that in any way contradicts what you think or say, you automatically start attacking their decisions and what they've said. Also what makes them experts? I have a ton of respect for them and will stand up for most of them if somebody here starts badmouthing them, but define "expert". Most of them have similar miles on theirs and have done similar amounts of work to theirs that I've done to mine, and it's just a hobby for them. What makes them experts? The fact that they're 30 years older than me? What you call "handholding and consulting for free" is what I call asking for other, more experienced peoples' insight, applied to a more specific application, and not wanting to make stupid and expensive mistakes on something you don't know much about, and asking for help when you know you need it.

I was under the impression that this forum had both newbies and people that had a lot of experience, and that the whole point was to be able to gather all of the info you can/need, and ask questions, and MAYBE EVEN MAKE SOME FRIENDS 馃槸馃槸馃槸. And because everybody has different applications (being a generic DIY EV forum rather than an EV Jeep forum or an EV Subi forum or something) and different expectations, they'll have different questions. Additionally they have different backgrounds and different lives.

In both this thread and my build thread, you've been very very accusational and condescendingly sarcastic, and telling everyone that they're wrong and borderline attacking what they say. And saying that there's a ton of info here. Yet you haven't actually answered any specific questions, nor provided any links or any baseline for what you're saying. I'm sure you're very knowledgeable with EV swaps, but it doesn't gain anybody anything for you to passionately attack people and not drop it, and say that there "is a lot of info" here. We know there's a lot of info here or they wouldn't have joined. I hope you don't see this as an attack, it's not. And I would like it if you can provide info/answer my technical questions--like I said I'm sure you have a lot of information.

Hello there It's good to hear that mechanical engineering is your area of passion. Additionally, you have access to even higher rewards and challenges through your ideas and fantasies. It necessitates proficiency in mechanical and electrical engineering as well as an understanding of battery technology control systems. Thoughts are with you as you pursue your academic and professional goals.

Thank you! Still waiting for August to roll around...馃お
