How To Build A Fast Slow Car, Fast 

The engine mount bolt access holes are absolutely beautiful. I do my best work when it is destined to be unnecessary.

Old and busted: throwing dog poop in your neighbor's yard. New hotness: throwing a class D magnesium fire in your neighbor's yard. ALL HAIL THE HYPNOT.... ALGORITHM. .

It is impossible to be "behind on videos" when you are building something as awesome as this

Sounds like you're the type of person that has his clocks set a few minutes later to make it to places on time!

"What do normal people do when they aren't in a garage ? I guess I'll never know." Now, that was relatable.

Don't sweat it on deadlines as Project Binky got me through from middle school to the nursing home. Some may call that an obsession, I just say it's not that bad.

"What do normal people do when they leave the garage?" I don't know, I'm the opposite. Wanting to be in the garage but not able to... living vicariously through the very entertaining and informative RU-vidrs I watch such as yourself. Keep up the fine work you do.

Given how many close fits you have here, have you discovered the joy that is self-adhesive UHMW tape? I keep it on hand in a few thicknesses. When you have a couple of pieces of metal that you think might interfere, stick a chunk of the tape there. It will provide a self-lubricating wear layer that both prevents damage and serves as a witness mark so you know if contact is happening. It's also useful when you want metal to slide against other metal with relatively little friction, but there isn't enough friction to justify a more complex bearing.

You and “This Old Tony” should do a collab, you seem to have the same sense of humor. Also, what top speed are you shooting for over how many miles?

I'd like to say that Matt's approach is the "educated send it" approach. Mix that with the dry humor and it makes for a great combination.

Tremendously interesting and amusing. You should keep making these.

It's really really important to set yourself up for deadline failure, having unrealistic goals forces you to order parts and plan everything out effectively

I hope that SendCutSend are really looking after you Matt, because you're giving so many of us such great ideas for how to use their services. I will be fascinated to see what the speed differences ends up being between the 2 and 4 cylinder configurations. I love this build!

I’m not an engineer but I build things. Seeing you struggle make me feel better about my struggle.

You're an engineer first, then a RU-vidr. The more work you get done, the sooner she's rolling and we can enjoy it with you. Everything looks awesome.

We’re all gonna die with at least one unfinished project in our shop. All we can hope for is that it’s not going to be current project.

The helicopter I flew in the USMC used the fuel to cool the engine oil. That could save you the trouble of a water tank, and just adding an air to liquid cooler would cool the fuel. Would need to have a return fuel system too.

Your welder time lapse comment made my entire day as a full time youtuber. Nothing drives me nuts more. Then what should be a 10 minutes video that is 25 cause ever 3 minutes is a welding cut seen or a lathe.

Excellent episode Matt - you *do* like a tight fit on this car, don't you? 😱😆 - are you watching what you eat in case the cockpit area turns out to be similarly snug? Are you making a bodyshell for the beast?🤔 Algorithm serviced - episode shared...👍

That Clovis and countersink bolt is slick. I appreciate the time it takes to source things like that.

Ton of progress Matt! I can't believe how fast you are designing and building a racing car with so many custom pieces in this short amount of time, with that many parallel projects going on at the same time... 💪🏼

Watching this show got me interested in autocad. Got an online course and spent about forty hours learning 3D design. Best thing I've done this year

There is also a series on YT called "Let's front half a 330 mph top fuel dragster" by Rob Wendland. The construction is similar to your car and he is a very practical and down-to-earth guy that is extremely experienced

The engine mount holes will come in handy when the threads pull out and you will praise yourself saying you knew all along. All hail the algorithm, send cut send, garage life is my life, Only time I'm out of the garage is to watch SFM and ToT.

The rectifier "heatsink" right next to the exhaust manifold is another example of "not a smart man" but its easily moved and you are a hero, we love what you do, don't change. Sometimes fail and fix even that happens beats doing nothing every time

This is the most awesome build I've seen yet on RU-vid the accuracy to which you build things is fantastic.

Human to human, I love this dude.

Awesome, stoked to see it this weekend!!!

Something that you may find interesting is that running a mechanical water pump actually robs a fair amount of HP from the engine. It could potentially be worth it to explore the idea of running an electronic water pump to cool the engine off of a slightly larger light weight lithium battery(only larger if you decide to not run the rectifier for your runs). This method is newly being used in professional motocross where it’s gaining 3-5hp in 250cc single cylinders(this is with the little bit of extra draw from the stator). I imagine you could pick up a somewhat significant amount of hp for a very small amount of added weight. Especially with how much water is being pushed through that motor and the rectifier disconnected. Usually the impeller is just removed from the water pump and the shaft seal remains.

Schedule schmedule. All I count is what the gauge shows on the fun meter. Shhhh, The show is starting.

Another great Friday when we get to hear from Matt. Thanks for the updates all around. I too am not sure what people do when they are not in their garages.

Today I learned "Engineering Intuition" means "Add more struts". Also, if you're contemplating disconnecting your battery from its charger at high RPM, you may want to consider the weight and charge/discharge efficiencies of replacing the battery with a small super capacitor bank. You will need to jumpstart the engine from something else, but once it does start, it will run significantly better than with a lossy Lead-Acid charge/discharge cycle. Works Cited: My riding mower.

the most exciting part about this is the "we will find out" parts....and i cant wait to find out, cheers brother!

I have been building radio controlled 1/10 scale rocket cars. They look like Landspeed streamliners. Use very powerful solid boosters. Can relate to your creativity. They're all hand made. Very fast.

Two maxims that follow "know thyself" were "nothing to excess" and "certainty brings insanity". I think you do very well at balancing those three. Sure do enjoy your videos; you got some good project in-progress.

IMHO, I’ve used Steel-It on my offroad buggies since it first came out. I think it’s a little overrate especially now with its much higher price. Curious why black? Silver or grey is best for racing as you can detect oil leaks and metal cracking/fatigue much easier

A lot of drag racer engines in some of the more "street" classes are cooled by an "ice box," which is essentially what you have already, just add ice. They run this "ice water" into the engine block. Doing that and eliminating the heat exchanger will be way more efficient. This gives you another 40 or 50 degrees lower water temp on the cool side.

Nice work 👍. I got a chuckle out of the threaded engine mounts, now you can get

Looking forward to seeing this finished, good luck.

You should wire the rectifier to an air conditioning button so you can turn off the AC for more power 😎

Your videos are brilliant. I like the way you explain everything. How you figure stuff out. Make mistakes. And go forward. Real life keep up the videos on the car.

It's pure pleasure to see you work and listen to your comments.

Great progress. The Wright kind of dry sarcasm is beautiful.

Super fun to see this project coming together. All hail the algorithm!

I don't know what exactly you're doing, but you are damn entertaining doing it. Thusly I shall continue watching! Excellent work, whatever it is that you are doing. Tolerances schmalerances.

I love the fact that we live in a world where someone like you can actually make money doing something he loves AND entertaining and educating viewers at the same time. Before youtube we had TV and most of that was crap. It was crap in the 70s when we only had 7 channels. Now we have 1000 channels and it just takes longer to discover that all we have to watch is crap

You are honestly one of the greatest creators on RU-vid

Great progress! Thank you for sharing and keep up the great work!

11:39 this wouldn't be a problem if you hadn't taken the unnecessary step of welding the flanges to the tubes. They're just meant to push the thick tube in to the exhaust gasket in the port.

11:34 I was that smartass for a second but then I thought that you would probably need access to valve cover without removing the hottest part of exhaust...

This is so cool! Btw, your sarcasm is hilarious. Keep it coming.

All welding projects i have had, have one thing in common: a few holes: 1,5 m2 new sheet metal, don't take long: 2,5 months, I don't restore this off road Toyota HJ61: it have to be factory...

Well done and good progress. Sometimes I feel the journey to reaching deadlines is asymptotic ...... I progressively get halfway there each day. WRT your frame mods, it reminded me of how an engine is mounted to a vintage R-1340 Stearman Motor Mount!

This is just way too cool! Can't wait for August. Will be cheering for ya kiddo!

Awesome!!! Always looking forward to these videos!

4:04 That's SuperCloseMatt 😉

Thanks, absolute info bukkake. Happy to receive.

Interesting project, looking forward to seeing it run.

Talking about your close fits, I have a saying "An inch is good as a mile and a thou is as good as an inch therefore, a thou is as good as a mile".

It's been said a lot of times, but you deserve a lot more subs! Awesome stuff 😎

Might want to move that rectifier, heat kills those things. I used to have them fry and blow up batteries in a "Cafe racer" I had where I mounted it under the seat with no air-flow... I did this 4 times before I was told that these things get hot. Love these videos

This is just incredible. I love these videos so much. I wanna be an engineer like you

Hey Matt. Good job. Thanks for giving me something to watch while I eat lunch.

Thank you! for bringing attention to the ridiculously lazy timelapse youtuber style.

Loving the Channel, great work. :D

When we aren´t in the garage we watch youtube about people who are in the garage. Nice Video and nice project.

Huge progress! Congrats.

So close yet so far.... BEST DAMN PROJECT IN THE MATT UNIVERSE

Heyyyy maaan!! No, I don’t think you will get into any trouble saying quarter midgets being in reference to race cars..!🤣 I say it a lot in my old videos that I took down many years ago. My kids raced them for years. Over 30. Nephews, my kids and ex girlfriend’s kids, so on and so on. AFCO shocks are awesome shocks to use. The internals are very adjustable and with Eibock springs you can really dial in the rear end. Hope this helps!! Ps. I liked the let’s install the motor comment with the engine clip! I mean, let’s be politically correct these days! 🤣🤣🤦🏻‍♂️❤️🙏🏻

The amount of uncertainty is fascinating! Love it! 😂

I’ve melted the nylon in nyloc nuts because i put them near hot things on my jeep. Might be worth it to check those after you put some heat through the brakes.

So far I haven't found a single youtuber of any stature who is a knower of all things.

You're logic on project deadlines is flawless.

Hi. Don't worry, stuff outside the garage is way less interesting (and thus less important) than stuff in the garage. Thanks for the vid, as always, it keeps the spirit up!

@9:33 "I could do some thermal engineering, but I think".. I'ma just send it.

Just my 2 cents: The OEM Regulator/Rectifier will be a diode shunt regulator, wasting some 30-60W of Power once the Battery is full. If you care, either buy one of the MOSFET Series-Regulators (less power losses) or place the relay between one of the three input phases from the alternator. The latter (cutting one of the phases) is sometimes done in "professional" racing. BTW nice project :)

Awesome as always just ordered one of your T's. I will be the envy of my friends

Bolt the headers on pointing down cut them off leaving a 3” stub, flip them and fabricate it to have the collector centered over the engine, heading straight out like you planned with 180degrees less back pressure

I'm interested in how well that heat exchanger works. 9:38 I have a turbo diesel with a air to water inter-cooler setup. I was looking to add a ice box without directly connecting it to the A2W loop. I had purchased a similar W2W plate heat exchanger so I'm interested how it works in your application. Love the content!

I like where this is going and how you do it and explain it to us how you do it.

Looking at the diameter of those coil over springs... yeah I'll say you're over sprung! Did you consider using 2*4's? I think they have about the same rate at that weight. ;) How about just moving ONE of them into the middle? Linkages of course need modding. But at least you can use what you've got... AND you get a free spare!

In front of the driver cage, there would ideally be a 'crush zone'. This implies not using simple longitudinal girders, but an angled-element (foldable) design that can smoothly crush for a more comfortable crash. Advanced designs would limit peak deacceleration force. Yes, acknowledge that it'll be run in an open area, but still... If there's a tree within 200 miles it'll eventually crash into it.

As always great work and love the video style xD

Man I love these.

I am genuinely excited about this car

Thnx, great videos!

I won't tell. Also glad you added extra bolts at car chassis union.

Excellent as always😎

Love your work 👍

It doesn't matter what other people do when they're not in the garage. That part of life is a waste. I put a desk in my garage so that I can do desk stuff there, too, when I need to. The garage is always a better place to be.

I just finished a big project - fortunately I still have several other projects to start, so no worries about doing "life stuff"

I was hoping that you were able to use some of that “TV Magic” and be running on the lake today ! Can’t wait to see it out there…

I like this sort of video, making and engineering things and the way you do it with adding in how u do it with the computer in 3D is good cos Im not the best with computers but anything hands on I'm on it 💯💯💯👊👍👍👍

Q: what do people do when they’re not in the garage? A: they’re at the Petersen Museum staving off range anxiety.

Something I’ve heard from race car builders like you, one time someone said how it takes 3 times as long as you plan it, I know how Kevin Talbot didn’t plan for a frame to sit for 2 plus years to now basically be complete. Life Motorsport with their pikes peak cars… The point is, a goal will get you closer to accomplishing it then not one at all.

I just know if I was your neighbour, I'd be obnoxious, we would yell a bit and then end up having way to many beers together and bitch about things. Love it. Cheers mate. 🍻❤😁

Woo! Cone Eng! I'm so glad someone else knows about them. They have some GREAT shit.

As a guy who has never really had any game in the garage, I usually drive my hobby cars, go for long walks and I've recently taken up bicycle riding, for the first time in almost 30 years.

Looks like you would really make use of plasma table. I just got a small langmuir table and love it.

I love the voice in your head. It reduces me to a giggling mess. Keep digressing
