I walked away and continued with my shopping, and I heard him chuckle as I walked off. When I came to pay for my stuff up front I saw him trying to walk out the doors with like fifteen Milky Ways in his hands without paying. The girl at the counter was very nice about it and professional, and was like “Sir, you need to pay for those first.” At first he kept pretending to be tired and not hear her, but eventually turned back around and brought them to the counter. When she took one of the bars and started scanning it multiple times, he stopped her and told her to scan them each individually “to prevent any electrical infetterence,” and then turned around and winked at me. I don’t even think that’s a word. After she scanned each bar and put them in a bag and started to say the price, he kept interrupting her by yawning really loudly.

@Mike_Costello 2 года назад

Speaking of safety, it was noted in a previous video that the electric assisted steering you have is going to fail because you have the assist on the input side of the steering box. With a hydraulic assisted steering box the electric assist needs to be on the lower or output side or you are going to rip the internals of the box apart and have ZERO steering when it happens. The input side is designed for the low force, ie your arms, it's the output side that's boosted. You've boosted the input and that wont hold.

Love this video series! Here’s a piece of info on the HMMWV and the way they were designed to work originally. It’s called throttle/brake modulation. When you feel wheel slip, let up on the throttle. Then you put your left foot on the brake, right foot on the accelerator. Then you accelerate more or less and brake more or less depending on what you’re feeling the vehicle do. It’s been ages since I learned about this, but you should look it up and give it a try!

@brianb-p6586 Год назад

That's just for when one tire is losing traction; it allows the Torsen diff to effectively drive the other tire on the same axle. In a modern vehicle the traction control system would apply the brake to just the spinning tire, which is much more effective.

You should weld up an steel "cage" for the middle driveshaft so it it fails again you prevent it bouncing around to much and may damadge the batteries. Have it to be 1 cm clearance up and down (maximum suspension travel) and 2 cm to the sides or a little more to not be hit while the rear flexes in corners.. Easy job and may save your vehicle/batteries/life

There's an orientation to the yokes on a drive line that make a difference on how the universals wear. You need to line up the yokes from the transmission to the rear end. Check with a drive line specialty shop to make sure, it's been 45 years since I've last done this.

You are right. The u joints/slip yoke that is on the drive shaft need to be in line with one another. Looks like he just slipped it on. Hopefully he got them inphase. Also. If those gears are new.

@NitroNuggetTV 2 года назад

youre mostly right but its more to do with how they're driven, with ICE you can replicate the same instant torque loading by dumping the clutch at high rpm, which also generally ends with you finding the drivetrains "weakest link" lol. This is why its quite important to have a "slow start" function mapped into the ECU for electric conversions.

@twpvw5 2 года назад

Those Torsen differentials are super cool, they "multiply" the torque the spinning wheel sees sending it to the stationary one. On the last climbing test you probably would have been able to make it by gently applying the brakes, making the torque on the spinning wheel appear to be higher causing a multiple of that torque to go to the stationary one. The exact multiple here is dictated by the friction surfaces of a washer pack between the two gears that the output shafts insert into, it can be tuned to a certain degree but is a bit of a pain to do consistently.

@DonnieTipton 2 года назад

I've always been taught than when measuring the preload on the pinion you want to get the measurement while the pinion is moving, and not the initial value. The reason I was told is that it takes more torque to initially move the pinion than it does to maintain movement.

@pierpaoloscian5926 Год назад

Ofc due to sliding friction. The static coefficient is usually higher than the dynamic coefficient, i.e. you have to input more force to wind friction to initiate movement rather than the force needed to maintain the same movement

> You mean the drive shaft support line? A wonder that line didn't wrap around the drive shaft and cause a major 911 environmental insult.

Aluminium skid plate protect your underside, but also it improves drag coefficiency by quite a lot! So it becomes more aerodynamic without ruining the look of the hummer, definitely a worthwhile upgrade.

@jessebrook1688 2 года назад

So, it'll be less than 1.0cd? Cool.

@tasmedic 2 года назад

Hummer + Drag coefficient = oxymoron. Everything above the skid plate still has the aerodynamics of a brick.

@SMGJohn 2 года назад

@@tasmedic If it means 5 - 15 more km of range, its better than sitting around and mopping like you have nothing better to do in life.

I don't know if anyone has said this before.... You have the absolute best "radio voice" ever! Great build, love everything about this build!

@mahamed585 2 года назад

When anything related to the gears meshing you must calculate the diametral pitch which is Pd = number of gear teeth / diameter of the gear, and the two gears must have the same value.

You've inspired me to do my own EV conversion. I'm planning on doing it to a Subaru BRZ. Planning out this project and researching all of this stuff reignited this love for JDMs I thought I lost when I enlisted and got stationed in Germany (the most anti car modification country I could ever end up in Europe). Thank you for this series man. Whenever I get the project running maybe I'll start my own series on buying JDMs from Coparts and rebuilding them into EV super cars 😂

It still wouldn’t be a supercar

@AndyGneiss 2 года назад

This sounds really cool. I'd love to see the engineering behind a BRZ EV conversion.

When I get my hands Ona Koenigsegg gamura I'm going to put a turbo S motor in it.

@Ryukachoo 2 года назад

You're going to have to be okay with a very low range so that your battery mass doesn't completely ruin the BRZ's balance. Definitely plan to install some kind of fast charging on there to make up for it

Can't help but think an under body shield may be a good idea, especially if you're going off road a decent amount. Glad to see it coming together so well.

We need updates brother what happened to this series we eagerly awaited

Hey Zach, I see an issue around 0:20. Let me know if you need to me to give you a hand identifying the issue.

I love the response even after it snapped, any lesser person would’ve considered ignoring her because of the stress.

@zasachnas 2 года назад

just love the hummer series, Jerry's calming voice and a car video in one!

@SuperAdventureMan Год назад

Hi Jerry, my 3yo and I loved watching the hummer videos. If you don't mind could you please update us on whether or not there will be another video regarding the hummer. Thanks!!

@T0phT0ph 2 года назад

Hey, did you ever think about driving the finished truck over to Ammo NYC? I think that would be such a great collab and a propper "finish" to a great build!

@saablazer1658 2 года назад

Driving an open Hummer from Utah to New York sounds terrible. However it would be cool to see.

@KyleJadin 2 года назад

The Crush Sleeve (metal ring) is meant for keeping the bearings with the right amount of play, its wouldn't cause this. If the nut is to tight or loose it will just do premature wear on the pinion bearings

@nathanzellmer9392 2 года назад

Hey, sorry to bother but I've been really curious about how you figured out the power train you needed to pull this beast around. Im looking into building an older 1966 f-100 into an E-Truck but I can't figure out how people figure out what their motor needs to be able to do, what controllers will work with what motors and so forth. I'd love some feedback on how you figured out your system and built it up!

@skeetermcswagger0U812 2 года назад

At 1st I thought you weren't that bright until I saw the way you break the metal straps with 2 Crescent wrenches on your packages then I knew you were probably pretty sharp.

What happened to the hummer project?

@memd777 2 года назад

can you do offroad comparison with non-electric hummer? maybe with ChrisFix vs Your hummer, would be interesting to see... or any other gas hummer, I wanna see how much more your capable is than the average hummer

Wondering if installing a joint that can take way more force is a good idea actually, the fault just snapped off a bolt, but what if the fault is still there and now something else needs to break?
