REBUILDING A WRECKED PORSCHE 911 GT3 | PART 4 

the restoration grind continues 🏎💯

Matt is single handed carrying 2023 with This rebuild. Can’t wait for the next episode

The Li-Ion battery in the Porsche (looks like it's an A123-made model) has an internal relay that opens when the battery experiences under/over-voltage and over-temp as a protection. When the relay opens due to under-voltage (as yours most likely did), the only way to get the relay to close is to apply a ~12V potential across the terminals, and then proceed to apply a charging current until the battery reaches the minimum SOC to keep the relay closed (usually anywhere from 15-30% - this can be programmed to any value by the car or battery manufacturer). This is why the voltage started reading once the other 12V battery was connected to it. Modern 12V Li-Ion batteries are very smart and have many protective features; they also last about 10 years if maintained properly!

Freddie is a great guy, very knowledgeable, and has the biggest heart. It's so awesome to see him open his door to you for you to do this.

your dad laughing at you is the most genuine thing i have seen in a while... he is awesome

Absolutely loving this! You may of found this out already now regarding the lithium battery but…the reason it appeared to be completely flat is because inside the battery casing is a control unit and switched contacts. When the charge rate drops to around 11.7 volts the contacts open to save the battery from being damaged. If you ever find this again most chargers won’t send voltage until it sees a circuit…which you won’t have when the contacts inside the battery are open. This is why when you connected the additional battery the contacts closed👌 I used to work in a Porsche Center and having to explain this everyday was a challenge haha! Keep up the great work😎 12:44

didn't realize how genuinely good of a person tavarish is, dude really goes out of his way for people, really defines the type of character he is, glad he was able to help matt out so much 🔥🙏🏼

I love how giggly mat is, really makes these feel so lighthearted and wholesome, probably one of the main reasons I keep coming back

Not only Freddie is such a nice guy and love to help out, but also a genius figure out a way how to recharge the battery

A wonderful rebuild. Top marks to your cameraman, he doesn't bob all over the place. He pans back and let's the people do the movement. This is the method that the majority of professionals should learn. Give him £20 and a Mars bar.🎉

I wasn’t expecting another video so soon! 🎉 Awesome work on the GT3! My favorite rebuild series of yours to date.

Looking great so far. On the airbag thing. I had a crash a couple months ago where 4 airbags deployed. It’s incredibly loud and I couldn’t hear out of my left ear for a few minutes. Definitely a scary experience not to mention the crash. But I walked away unharmed as did the other in the accident thankfully so they did the job.

Mat is a cheerful lad with fantastic spirits & Jack is an awesome dude with great skills= great job on the GT3! Great job Guys!

Well done Freddy, clever with the battery situation saved you a fortune Mat. Great video as always loving this build...... I love all the builds!

Watching these episodes makes me wish I could be part of a rebuild. It must be such a great feeling to see these beautiful cars back in working order after all that time and effort. I love how everyone is so happy seeing one more part of the build restored.

Always smiling with this big cost rebuild! So much respect! Is there a video how all of this and your channel got started? You have a New subscriber! 😎

great videos matt, cant wait for GT3 to come back to its former glory! also, the roar of the engine is effin amazing!

Very clever editing on these videos Matt! I don’t think people realise how much it contributes to the success of this channel.

Mat your desire and love for cars is insane ! Repairing those cars is really a master act ! Hands down bro. Greetings and wish you all the best. A master mechanic from Germany ( BMW ) :-)

Mat super happy for you buddy, What a car you have. It's gonna be wicked when its fixed.

My favourite BRvid content full stop! Keep it coming Mat, just so satisfying seeing these cars coming back to life.

Loving this already 😘😘😘 I wished this video comes out daily 😔 Thanks Matt hoping to get into rebuilding vehicles ☺️☺️

This is seriously enjoyable to watch and see how it is being fixed!

My favorite series on BRvid right now (P.S. Mat if you need any sneakers while in The US lemme know I’ll take care of you 😏)

Mat love what you are doing brother excellent helping out the Gentlemen respect.

Loved this one mat you guys are having such a great time in the sun shine building the 911GT its going to be amazing when you drive it for the first time. Well done guys team work is the dream work. Stay safe michael UK 👍

I honestly love this content. You are such a positiv guy, a real lunatic in a good sense. It must be great fun working with. Keep up the great work and videos.

Just found your channel, unbeliveable it took this long, pure mega-quality, easily one of the very best car-channels and i will watch every video (i have a lot to catch up😊) 👌🏻

Thanks for your content Mat, Hannah, Dad, and the rest of the team and Family. Peace and Blessings to you all

Love how your dad just laughs at you when things don’t go to plan. Proper dad 😂

Great work. So satisfying watching you all repair and put it all together.

What a legend! Been watching since the Bentley days, made being in lockdown that little less boring. Currently at Uni studying motorsport engineering and loving the videos keep smashing it Mat

Brilliant work Matt and Team! Great to see how you working with your Dad on your builds! 👏😎

Keep 'm coming Mat. You are keeping me on the edge of my seat each time 😉 Great fun!!!

This is my favourite channel on BRvid,I can’t wait for the next episode. I only found it a couple of weeks ago,and I’ve watched every single episode. Fantastic stuff.

What a amazing guy Freddie is 🎉

Such a huge job on this gt3🙌 Love your videos. Such a pleasure to watch🙌 🇩🇰🇩🇰🇩🇰

Awesome job you guys are doing a great job, well done 👍🏾

Fantastic vids Mat, definitely some of the highest quality car content on BRvid! Keep it up!

I'm not even into cars that much but these videos are so positive and inspiring, I love them.

The best car BRvidr on the platform hands down. I actually look forward to him dropping videos on this build and I’m usually not like that keep going bro!

I absolutely love seeing the bond you have with your father. Him laughing when the horn didn't work was incredible!

I am dying to see it on the road Matt, ! I hope so much its all going to work out for you and the team!!! Still fingers crossed!!!

I think this car is a start to more builds in the states! Love your work Mat.

Massive thanks to you MAT for these videos - Every time I see these videos, it's like dream come true in some way for me as well! Keep it up!

I always get goosebumps when I see a new video from Mat. It's crazy how it excites me seeing someone doing something they genuinely love. Keep up the good work mate!👍🏽

Great series so far, you got me as a sub. Love how you bringing in the whole family and making them smuggle parts lol Also it looks like you really like rebuilding these, it looks hard and rough but you're not afraid to start tackling it and I can only admire such mindset. It works out alot and when you hit a bump in the road you also tend to show it. And how you go about it and end up fixing it to. Like nothing can stop the project. Gonna be watching more because I've got this 335i sitting in the backyard and you spark up my motivation to get it going. So thanks for putting these out there.

Everyone needs a friend like Freddie what a guy

Your an absolute legend Matt. Keep up the great work.

Been watching your videos religiously for a while. Your story is amazing. Keep doing what you're doing, you're doing great!

Quality work Mat!! Car is looking sweet

It feels awesome to see while taking a small break from work and see how much work he is putting into this dream car!

I'm hooked on this build! So cool to have your Dad involved too, making some memories for sure. And Freddie the gang are so cool. You're not that far from the LZ compound. When it's built you should wake them all up by drifting around the place 😆

Was having a shit day and you’ve put a smile on my face dude fair play keep achieving your dreams 🤙

Can't wait for the next update. Subscribed because of this series. Keep it up! 😀

I love the way you make and edit your videos. Its a pleasure to watch!

Love the videos!! Makes my day so positive everytime, thanks mate!!

Great build so far. The best thing is the memories your making with your Dad

I'm on the edge of my seat waiting for it all to come together. I want to see it move under its own power with all 4 wheels on the ground. Nice job Mat, especially the dead battery hack. I've done that a couple times myself when the dead battery voltage is too low to get the charger to light up. It does work. Can't wait for the next chapter. God speed and God bless.

im actually glad when i see your new videos on my feed, your content is engaging, exciting and really unique. Its a blast to watch your videos

Really enjoying the gt3 videos! can’t wait for the next one

This project is getting better with every video added, very addictive to watch! Fair play Matt proper mint.

Nice job so far - (Mat et-al) to all of you involved in resurrecting this GT3

Been following Mat since the S5 when he had like 10k subscribers. Amazing how far you've come mate! Totally in love with your videos, you're my favorite BRvidrs of all time and my day is always brightened up when I see your notification!

Crazy to see your channel just keep growing! I remember watching when you were like 200k and thinking you deserved way more subs and now you are at 1.25million! A rare case where you deserve it and many more, I’ve never watched BRvid videos looking forward to the next video coming out! Best of luck to you I hope things just keep getting better✌️

The lithium ion iron phosphate (LFP) battery in the new porsches goes into a self protection mode when voltage goes too low. It just needs (as you discovered) brief application of charging voltage (12-14V) from another battery to re activate, and then should be charged to around 13.4-13.6V.

Man TJ fumbled the bag with a rebuild series on this amazing car. Good thing you picked it up and started it! Carrying 2023 BRvid on ya back!

Not a Porsch fan myself, but absolutely admire your enthusiasm. The love you put into this rebuild job is absolutely awe inspiring. Keep it on bud, your attitude is something to admire!

Mat you are great at what you do love it and you got yourself a new subscriber

Great job so far. Can't wait to see it back on the road. To get those parts you need in the US, or with anything else for that matter, you need to have connections. I find it hard to believe Freddy doesn't have the connections at a certified body shop to get the parts you need.

I can't explain the joy I get when I see you've uploaded a new video. Stoked to see your GT3 back on the road!

Freddy is a genius! It’s so impressive how he can think outside the box- saving a lot of money along the way

Legends! I need more Tav & Jack content in my life. I've always watched your videos from your BMX days but didnt know about Tavarish and all his antics! Time to go binge watch his channel (Y)

Well done matt 👍 your a top man and I love watching all the content you post love and best wishes to you and your family Michael Edinburgh 🏴󠁧󠁢󠁳󠁣󠁴󠁿

Genuinely my favourite channel at the moment, HUGE props to you! 👊🏼

You have so much patience and your positive attitude is infectious! I really hope this rebuild goes according to plan!

Freddy coming in clutch with the battery save, impressive thinking. Your dad laughing when the horn didn’t work 😂😂😂 that got me. Love this build!

I'm going to be honest here: there is not a single video on BRvid that I actually look forward to watching, like yours, Mat. You were made to do this. It's natural. The fact that you engage your dad and people around you in the amazing project is simply outstanding. Can't wait for the next wideo!

Can't get enough of your videos, I keep waiting impatiently for your next videos and the GT3 series is my favourite right now!

It’s great to see everything coming along!

Loving this series. You should do more international builds. Use your content to travel the world and fix exotic cars in amazing locations.

just incredible Mat I have never been so addicted to such a brilliant captivating series of videos 💪

Oh, a new video already? Let's go! This Porsche rebuild is sooo satisfying to watch

Freddie is a genius and a really nice guy🎉 I love to see how well you both guys work together 🙏🏽

i love how these videos are made with the commentary, it builds suspense. feels like i’m watching a national geographic show.

Your channel is addictive man! It’s just satisfying to watch how you’re rebuilding cars !

Mad to think from the Audi to now this , nearly 1 mil in a day !!!! Massive respect for what you do 🙌🏻

Keep it up guys loving the videos ❤

I love this series of Adam LZs fix up. I don’t really even enjoy car content like this but found this and now completely invested and subbed to your channel. Can’t wait for the next

You make my day man😁much love❤️🫵🏽 from South Africa 🇿🇦

Freddie is the unsung hero of this rebuild, I love this collab!

Absolutely mental to watch you guys put this thing back together. Super motivational, gotta hop back into my projects!!

It always feels like we're all experiencing the pain and frustrations together! You always find a way round the problems - I m sure there's a lesson in there somewhere!😄❤

I feel it's good to have extra parts for your car, just in case. You could meet an other GT3 owner that wants diff seatbelts 🙂

Wasn't expecting pt4 that quickly. Lucky me. Loving this build even beats the Bentley build this channel's first major car best thing about that build was the tour to Monica after. Hoping a road trip after this build also

On the 4:30 am bus to site in the Australian outback and can't ask for a better way to start the day than watching a new Mat Armstrong video. Keep up the great work Mat, you're an inspiration to many!!

Never been so excite to see a car being revived, I'm wishing to watch you drive one of the coolest porches out there.

By far the best auto channel on YT, good on ya Freddy and boys for the assist

This man is making me smile every time he uploads. Thank you Matt for letting me have a great time ❤️

Best series on You Tube - positive / but realistic / great work 🏁🏁
