S550 Upside Down and on the Wrong Side Build Thread Profile - S550 Mustangs

This is why I opted to mount my battery behind the pass seat.
The cable weighs more than the battery so moving the battery to the trunk would be of no benefit.
Plus, less cable means less voltage drop.

Like the box and hold down. If in the cockpit it needs to be properly secured and isolated.

That's the smallest plastic ATV battery box I could find and the battery is tiny so that box is stuffed with foam.
The frame I made from aluminum angle and the hold down is 1/8" stainless steel strap.
Been rocking that setup since the 2021 racing season. So far so good.

I will say this though....do NOT let this battery overheat. Charge it S-L-O-W.....
I let mine go dead running the electric water pump and then started the motor without letting the battery cool off and the alternator was enough to cook the battery and sh!t got real pretty dang fast....

Like Sal said!!! I had a similar issue. I killed the battery, put on a conventional charger and got it running. Then I noticed a "Swelled" battery case. I guess not all lithium batters burst into flames when abused.
PSA. Don't mess with a Lithium battery. Follow the directions. Which for me is hard since I rarely read directions, the first time around.

Exactly where it is in my 944, leave me alone in my delusion that its still a road car.
Well it does have air con and a full interior.

Haha, i actually read the instructions down to the point where it says to disconnect the battery if jump starting. Yeah they are sensitive little things.

Getting all that smoke back into the battery would have kept you busy.
I got to page 45 of your build last night. That blower motor must have been fun.

Yeah, I jumped it with the battery charger and pulled it off right away and let the alternator charge the battery and that was too much for it.....

It was....ultimately the car was faster with the N/A Coyote and suspension upgrades.
But boy did that thing haul azz down the straightaways.

Naw all the smoke was gone outta that one so I have to replace the battery with a fresh smoke filled one.

Lucky i have access to a lot of cable. One of the supervisors said he hadn't seen me on the factory floor this much. He laughed when i told him it was caus i was getting supplies for this project.

This might be a bit big. But what voltage drop.

Do it!

Looks like this might be easier than i thought. Still need to get parts made but pretty straight forward.
This was my original spherical bearing with top nut and lower part is part of the spring plat form. The 2 bearing are similar in height, like close enough not to be worried.
I just have to have those parts remade for the slightly larger 3/4' bore. Tweaked the design to simplify as i know how much clearance they will need. Extended the top nut to get a socket onto it as its buried deep in the FP350S housing and done.

Will revisit the top nut as its slightly smaller than the outer edge of the bearing top face, might got up a socket size and see if it will still clear.
First iteration and its now midnight so that will do for today.

After numerous attempts to get someone to actually do what they said they would do i gave in. So much for getting them machined by someone local.
https://craftcloud3d.com/ to the rescue.
Had them 3d printed in stainless steel and the threads machined in China. $200 AUD delivered. Just turned up at work 10 minutes ago. Fingers crossed. Worst case i redo them and have them machined but i thought i'd give the 3d print a go.

 

[GAR944]

Well it fits nicely. Smaller & longer 19mm head gives way more clearance for the socket. I may have got this one right.

Also finished proof of concept for the overflow tank. Now just waiting on some aluminum barb fittings to replace the plastic ones i used during mock up. And some matching hose clamps rather than the mixed bag i had lying around.
I'll run it and see whether i need to get the support bracket made in something stronger than PETG. Pure luck the lip on the coolant tank sits on top of the positive terminal bracket.
Had a win there. And the cap just touches the rubber sealing strip on the bonnet. Someone was looking out for me on this one.

What are those massive camber plates? I have never seen anything like them.
