So the linkage would just consist of an arm that attaches to the dowel sticking out the side (facing us in the screenshot)?
Yes. The idea was to use stock cables with the cross over possibly being used as a reverse lockout but I hadn't got that far before crossing to the dark side. I'm not sure if it would be needed or not if a neutral position was put between 1st and reverse. The other side would have accommodations for a sensor to output a resistance/gear position.
Re: BadAss SRT-Z - 2.4L / A568 - Update!!!
Been a looong week and a half since the "1st gear episode".
Sunday 7/29 after I got home from the track, diagnosed flywheel was loose.
Monday 7/30 order new clutch (same as before ACT twin disk) and disassemble trans in car - internals looked OK except the 1st gear blocks had corners rolled over. (Liberty's said it was OK as long as no cracks)
Wed-Thurs 8/1-2 out of town for work
Friday 8/3 new clutch arrived and after work took trans case out of car. All week I had gone back and forth on which trans goes back in and I decided to put the face plated trans back in to test it at the Mopar Nats the following (this) weekend. Until I took the trans out and saw the bellhousing side was wet - WTF! I brake cleaned the area and let it set overnight with bell housing down and some trans oil on the inside of case. Also took the clutch and flywheel out (bolts were all loose, must have hit hard as the threads were imprinted in the sides of the holes! some clutch material came off disks too and some weird material from crank deposited on flywheel not sure if that was from 1st gear episode or previous to that?)
Saturday morning went out and saw the bell housing was wet and see a small crack that looks like where the oil was coming from, right on the edge of the front bearing housing - damnit! this may or may not have happened during the 1st gear incident. this case was one of the worst I have ever seen with voids in bolt holes and visible laminarly layered areas that appeared to be aluminum in the die from a previous shot that ended up on this case. I ONLY used this case because it was already set up for the liberty gears and some machining and stops were put in. So, plan B, to put the trans that just came out back in after going through it. It had been thru 2016 and 2017 and was missing 3rd gear since HRDW 2017 and reminded me of that racing at SDAC-28 this year. The rest of Saturday was spend working this trans over including grabbing the 1-4 speed gears (and other parts) from the previous trans (the one the T850 diff came out of to put into the face-plate trans) and get it ready for assembly. New clutch went in (different bolts) , trans case with diff went in then built the rest of the trans in the car.
Sunday finished installing rest of stuff, changed engine oil (some debris came out, maybe the motor rattled an shook something loose? Also too the STS out and put in the old shifter (89 factory bend handle shorty) After getting it all together ran a compression test to see if any issues. looked OK across board. Then started it up and noticed the speedometer was moving and more than viscous shear - Hmmm... WTF... wait a minute, I put the 3-4 slider in backwards so it was in reverse :( So sunday nigh late, I took the trans back apart in the car and with was back together by 1:30am
Monday Fired it up and ran it for a bit and seemed OK but then started looking into why the #2 plug looked lean. Swapped in new plugs, even with cleaned injectors it was doing the same. Injectors had similar Ohm reading so thought they should Be OK. Swapped injector 1 and 2 and lean stayed at 1. checked power wire, all around 12.5V. Then checked signal (ground) wires from injector plug to computer, similar 0.5 ohm. Checked with noid light and all seemed to get some signal but was only cranking. Closed garage around 1:30am
Tuesday (yesterday) tried noid light again while cranking and saw it looked like they were all firing but then when running there was a noticeable difference when you touch each injector 1 and 2 softer than 3 and 4 (bank to bank system) So tried to tighten up terminals in injector plug, swapped in a different injector sub-harness, Checked connector terminal at computer plug looked OK. Peeled open harness from injector harness plug to firewall and also one spot harness touches under dash and no problems found. Checked harness side of injector sub-harness and couple terminals seemed looser so tightened those up. re-checked some stuff and wanted to test it but it was 1:30 so went to bed
Wednesday (today) I had to work all day so I could wrap things up and take the next couple days off to go to Mopar Nats. Soon as I got home I fired it up and it seemed to idle a little smoother and let it warn up some and checked the plugs. they all looked similar so must have been one of the connectors on the #2 signal wire... I hope. ALSO hope no damage from the 1st gear incident :/ Car is ready to load onto trailer tomorrow morning to head to Columbus. On a positive note, pulling the car out of garage to wash it (as far as I've driven it) the shifting felt great.

It's funny because the first thing I said in a text after he told me about the misshap was.
"Maybe time to pay DJ to engineer us a sequential shifter!!😉 I think he had one kind of designed before he decided to go rwd. I could help out with the machining."
I might be in for this! I'm OK with an H-pattern just need lock-outs working. I think the challenge with liberty sliders is no detents to find home so 2 easily flies right to 1st

Not terribly happy about their method of creation, especially since JT had a sickness for killing cases. Would be nice to drop in parts and go.
I did tell JT and Lengel I don't even care if they like it, I am already IN.
LOL, I like it and think it could work, just want to test it some more on track and street

Assuming JT's isn't modular, I would definitely replace the flywheel bolts.
With as hard as the bolts dented the flywheel holes I'm not sure I would even want to use that flywheel...

The kit we replaced it with came with a new solid flywheel and all.

Time for an overdue update on the #badassperformance #shelbyz which will come in multiple update posts... So with the goal of building the baddestass A568, earlier this year I picked up an A568 with a one-off set of faceplated 1-4 and custom sliders. I finally got a chance to assemble it in late July. In addition to the speed gears, modified case and input shaft, I swapped ring and pinion, Lengel modded T850 diff and chrome moly bearing plate and welded on a couple gussets too. This case had several issues of voids and delamination and probably the worst I had seen, however being modified with shift stops for the modded gears I decided to give it a try. More to come...

Episode 2 of the overdue update on the #badassperformance #shelbyz ... after installing the new race trans, went to #greatlakesdragaway #moparfest to make some test hits. First pass was easy to make sure the car got down the track with the new badass trans. The second pass on low boost (~20psi) went very well. This was the first time I ever WOT shifted 2nd gear in this car and banged 3 and 4 in line. I wasn’t racing the other guy just took my time launching. Unfortunately lit the tire in 1st then ran great, 11.13@131mph More to come...

Episode 3 of the overdue update on the #badassperformance #shelbyz ... after the good baseline low boost run with the new badass trans, went back up for another test hit. Similar launch low boost (~20psi), lit the tire, nailed 2nd at WOT, switched to high boost (~28psi), it pulled hard, went for 3rd... and got 1st! Crap! Luckily immediately realized what happened and re-clutched and got it out. Scanned gauges, oil pressure good, temp ok, car ran and drove but rattled, guessing the clutch took the hit and it did, the flywheel was loose! Thanks to Keith Dale for the video from the stands. More to come...

Episode IV “A New Hope” of the overdue update on the #badassperformance #shelbyz ... checking out the carnage to find out why the flywheel was loose... Engine oil looked ok, engine rotated easy. Trans, the 1st gear plate lugs were damaged, but gears not cracked. Case had a crack in bell housing, more likely from worlds worst casting than 1st gear episode. Clutch disks were hammered pretty good and flywheel was knocked loose, check out the bolt thread imprint in bores of flywheel bolt holes. At this time the thrash began to get it together to race the following weekend at the #moparnationals
Got a new #actclutch and flywheel, and bolts. Went thru the previous badass A568 that shifted poorly at #hrdw2017 and #sdac28 swapping in 1-4 gears and best combination of sliders and syncros from trans that the diff came out of for face plate trans. Changed engine oil. Swapped in stock shifter. Also had injectors cleaned and troubleshot injector #2 not getting good signal. When all together it ran smooth and shifted nicer than it had in quite while. Was excited to get it back out to race it in a couple days at #moparnats More to come...

Episode 5 of the overdue update on the #badassperformance #shelbyz ... arrived to the #moparnationals and had a good feeling, driving the car around it ran and felt great. Friday morning first call for “stick” class and went to staging lanes. Decided to leave soft, granny shift and run low boost. 4500rpm, feathered clutch and bogged off the line. Ran great in 2nd and 3rd then after shifting to 4th it quickly developed a vibration and KaBOOM! Then silence. I shut off fuel while quickly braking and pulling over out of the groove. Got out and it was pouring water out from hole in radiator and looked across and saw hole where #4 came out. Fuuuuuuuuu. Guess the 1st gear incident must have hurt that rod. That’s racing. Had a good long run with this engine. Now to diagnose the rest and plan what’s next... to add insult to injury, Mother Nature decided to dump on us too. More to come...

Well that really sucks! sorry to see that happen, takes all the fun out if it. :(Glad you didn't crash on your engine liquids.

Thanks guys, it sucks, but unfortunately comes as part of racing and now truly am learning why the 1-2-1 is referred to as the "money shift"
Yes Warren, you are 100% correct, it could have been MUCH worse at over 100mph on fluids! Luckily the only fluid put down was water (with water wetter) out of the radiator after rod/block shrapnel punctured it.
That engine had a good long run with tons of passes so not upset just will miss such a solid runner.
As an update, I called FM to see how long to build another 2.4L like this one or if same rods & pistons were available. Apparently he doesn't stock the long aluminum rods and corresponding JE pistons and was looking at a few weeks for pistons and 2 months for the Al rods.... However, he just happened to have a built SRT-4 long block that another customer backed out of... so it will hopefully ship out tomorrow. not out of Drag Week just yet...
Re: BadAss SRT-Z - 2.4L / A568 - Update!!!
Well, that sounds like a bit of good news!
Re: BadAss SRT-Z - 2.4L / A568 - Update!!!
Is the new motor going to have aluminum or steel rods?

aluminum... that's what it already had in it so a timing thing and FWIW they are stronger... they just didn't like the moneyshift

You know, a a413 sure cuts down on the chances of a moneyshift...
Just sayin'

#badassperformance #shelbyz new 2.4L bullet arrived from Forward Motion Wednesday night and began disassembly on Thursday night. This is a swap from the #poweredbybreeze 2.4L NA to the #SRT4 #neon #Turbo 2.4L so some modifications will need to be made. Time to continue the swap and modify parts as needed. Thanks to Marybeth for the fun “1st day” sign LOL!

#badassperformance #shelbyz old #poweredbybreeze 2.4L NA carnage pics. Found most of #4 rod in the pan. In addition to the block and rotating assembly and punctured radiator, the death toll rises with a cracked oil pan and damper. FML...
