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!

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

[Gregski]

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!

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

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.

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

man still no luck charging at the blink stations

neither one of these worked, not the one in front of McDonald's and not the one across the parking lot, for obvious reasons

have you reached out to blink to see why the charger wont recognize the super awesome evgmc?

yes, the first charge station they said was broken on their end and although they tried rebooting it, it never came up properly, they said they would need to send somebody out to service it, and the second one, well someone stole the plug off of of, I think I may try another station this weekend just for funsies

[Gregski]

ah sh!et they accepted my low ball offer, so here we go again, 6 hours and 368 miles to Los Angeles


A Day In The Life of an EV Converter 6 hours to LA for a battery pack!

Road trips are good for the soul!
