How to enhance the 0-60 acceleration?

Ok, now I’m curious as well. ?

Ah. I thought you had some secret tune figured out. ?

Wouldn’t be the first time someone put a password in the location part of their profile.

Haha it was my first time.. thank you guys!! I hope we get OTA for enhancing the performance!

It’s unlikely because of hardware, electronics, and electricals. I would love to see a kit to upgrade the rear motor, but there is too much support equipment (including stuff inside the battery case) that needs to be changed. ??

I would challenge the idea that “too much stuff” needs to be changed for it to be done.

Take a look at any aftermarket supercharger or turbo kit. If that isn’t “too much stuff,” I don’t think swapping out some wires and electrical components would be nearly as involved.

look at all these parts!

Oh, heck, that’s nothing compared to removing the Oldsmobile engine from my T/A after having built a real Pontiac mill for it. The difference is I can’t pull the battery case, separate it, replace the bus bars, replace half of the powertrain wiring harnesses, HVBJB, and power electronics, reprogram the PCM, SOBB, SOBDMC, etc. (OK, I can reprogram the modules). I’m sure there is other stuff to replace and reprogram. I just wish there was a kit for it rather than having to guess at it. ?‍?

Other than the programming that doesn’t exist yet, yes you can drop the battery and replace all that stuff.

Actually after watching my mechanic do the HVBJB recall I would say it’s waaaaaaay easier than installing a twin turbo kit.

That said I don’t think we would have to replace any of that stuff. Just a simple tune and you’re off to the races.

IF you burn out an HVBJB or bus bars or whatever, THEN you replace it.

But until then, why replace parts that aren’t broken? That’d be like swapping out a transmission on a modified ICE Mustang when you don’t have to unless it breaks

You’re not going to burn out the bus bars but the larger bars serve to reduce the probability that the HVBJB will melt. Think of it like the need to change valve springs when going to a hotter camshaft. You might get away with it if the original springs are somewhat new but once they’re a little worn your likelihood of floating the valves and contacting a piston goes up dramatically. We already know that the old bus bars with the third generation HVBJB can result in an SSN with the old power limit. Why poke the bear by increasing the amount of power and the time under power? ?‍?

Because that’s what I want! More power!!

Even a select RWD can burn out an HVBJB.

Can’t modify any car without fear of breaking something.

Do we know if the HVBJB for a 2024 GT is any different or if the bus bars are different?

Can Ford get rid of or reduce the power limit by updating remotely like OTA?

According to Ford VP Darren Palmer? Yes.

But it’s been quite a while since he promised that. Summer 2023.

The third generation HVBJB was released in mid-November of 2023. There haven’t been reports of a part number change since LK9Z-10C666-C (GT and Rally models) was introduced. @Mach-Lee reported that the bus bars are different, along with supporting electronics and electricals. So if Ford put in different stuff, you can bet that they have done their accelerated wear testing and projections in order to validate that these items were necessary to reduce their warranty costs (I.e. maintain some level of reliability). Put differently, when I canned an engine to run past 9.5K RPM, I knew I had to change connecting rods because even modified they were good to just past 8.6K. This also necessitated different pistons (due to the rods being slightly longer), a different ring package (harmonic resonance), titanium lifters, etc. ??

Yes, but you KNEW you had to modify those parts to rev that high.

I’m still not convinced 10 seconds of full power will blow stuff up when 5 seconds does not.

Especially since our motors lose power naturally past 30 mph anyways (around our peak tq). I don’t think the 70-110 mph full power is really much more demanding than what we already get.

From the temp scans for the sensors we do have, the temps spike for a fraction of a second and drop quickly even during our 5 seconds.

You knew you needed to upgrade those parts because you definitely would blow the motor up without them. Same as I did (upgraded all the parts) when I put a heads/cam package on my 2002 Trans Am.

Pack, bus bars, and HVBJB is still the same from what I understand. They upgraded some motor cables on the premium IIRC.

basically, there’s nothing inherent to the 21-23.5 hardware that should prevent these cars from matching the charge times of the 24-25s or the original GT/PE cars from getting past the 5 Second Rule.
