1. are you trapped in an old volts ohm?
2. have you run out of capacitors?
3. has the governor asked you not to charge your ev so you can run your ac?
4. are you not wired for it?
5. is your transformer now gas powered?
6. too much resistance?
7. you now think nucleus was an 80's rap band? (oh that one is actually true)
8. are you shielding us from updates?
9. your potentiameter broken?

Hilarious! :lol::lol::lol:

Re: My Dusty 71 GMCe Electruck
 

I'm dying over here laffing, thanks guys you made my day.

Life happened sold our house, got my own house, [I'll let you read between the lines] moved (yes using this ol' electric truck), just got settled, truck definitely needs some love.

Re: My Dusty 71 GMCe Electruck
 

sorry to hear you had to relocate. truck is looking good doing truck things!

Re: My Dusty 71 GMCe Electruck
 

Good luck with the new lifes circumstances. Glad to see you are getting settled in.

Re: My Dusty 71 GMCe Electruck
 

Bummer about the life changes, hopefully it's all for the best.

Re: My Dusty 71 GMCe Electruck
 

Moving is never any fun regardless of the reasons. ;) You take it easy Gregski.

Re: My Dusty 71 GMCe Electruck
 

Good to see you are posting again. Only thing I can say is my divorce was the best money I ever spent.

Good luck, Rg

Re: My Dusty 71 GMCe Electruck
 

I am seriously touched by all your kind words and support, I thought about sharing this and thought I would because if you love what you are doing than you must keep doing it no matter what life throws at you, divorce, cancer, death in the family, all the life roller coaster rides, and you know, this too shall pass.

So far it's been civil, and our kids are of adult age and now car parts can live in the house, know what I'm sayin'

Nothing better then sitting on the sofa with your morning cup of coffee in hand, starring at the coffee table, which is covered with balled up wire, zip ties, shrink tubing, wire loom, Prius, Volt, BMW, Tesla assorted electrical shocky things, misc HF tools.... and just smiling! ;)

Re: My Dusty 71 GMCe Electruck
 

So a little truck update, as you know Dusty is 53 years old so this morning she has a colonoscopy appointment

3.72 => 4.11

Re: My Dusty 71 GMCe Electruck
 

so Mike seems super nice and took the time to talk to me and said that the OEM parts I bought off eBay are less likely to be noisy unlike the much lower gear ratio after market ones he sells, so we agreed to give these a try

I only paid $120 for mine with tax and shipping on eBay, where as he wanted $400 for his 5.18s or something low ratio like that, I think it would have been fun to try those, but oh well

this place is only like 5 miles from my house, so that's a bonus!

Re: My Dusty 71 GMCe Electruck
 

Wow, truck is done, they did it in ONE DAY ! $750 out the door

Re: My Dusty 71 GMCe Electruck
 

Now I have some questions. What is your reason for the change? Is it now similar to the gearing the motors had in their original vehicle? What effect will this have on range? Is there an optimal motor RPM?

You do a great job of explaining things on this build so I can't wait to learn about this part too.

Re: My Dusty 71 GMCe Electruck
 

I think our brains are literally BluToofed, ha ha, you ask all the right questions

yes this was to match the gearing of the 2018 Lexus GS450h, I crunched those numbers a while back (so please don't make me do it again, I'll try to find the link to that post on the EV forum) and it seems like 4.11 with my tire combo will match that car

but also I always wanted to try 4.11s even when the vehicle was a gasser, and I think these motors inside of this Lexus transmission can spin up north of 15,000 RPM so they won't even bat an eye on this

I talked to Mike the tech in the shop who did the rear end upgrade and he looked at my drive shaft and said it would handle the 5.38 aftermarket gear set if I wanted to go that low in the gear ratio (forgive me I get so confused with the high numbers vs low gear ratios that I couldn't tell you what's low gear or high gear, etc, ha ha still learning that stuff)

""Tall" gears and "short" gears are referring to the gear ratios.

Tall (high) gears have LOWER numerical numbers such as 2.79, 2.90, 3.00, 3.25.

Short (low) gears have HIGHER numerical numbers, such as 4.11, 4.30, 4.56, 4.88, 5.13, 5.36, etc.

In simple terms, the numbers mean how many turns of the drive shaft to one turn of the rear wheel."

not sure how this will effect range, but it will effect Top Speed, something I ought to should test

every year I forget what tire size I am running so I will post it here 215/65 R17 and here's what my buddy did for us to show the RPM difference assuming I had a 27" tire but that's ok
