@@_Gingium_ sorry man someone had to say it. But I’m definitely excited to see what you’re going to do in the future! Been here since the og rally Miata can’t believe how far you have come since then keep up the good work!!
Advice from a HVAC engineer:
You probably had 200 guys already comment, but you don’t want to hard connect a fume extraction to the exhaust, as the resistance in the duct will take away horsepower. Just have a funnel on the end of the duct and a stand to hold it a few inches away from the exhaust. Simply Google “exhaust at a dyno” and you’ll see what it looks like. HOWEVER, you then need a fan to create negative pressure so the fumes go into the funnel on the duct.
This is where you need to size the fan. So, a 5L engine at 6000rpm is going to blow 250l/s of exhaust, but as the funnel is placed a few inches from the exhaust it will pull not just air from the car’s exhaust, but also room air from around the funnel, so you probably need a fan sucking at least double, thus 500l/s.
But, we’re not done sizing the fan, as you have a “fan curve” which is flow (l/s) over resistance of static pressure (Pa), so you then need to calculate pressure loss of your duct. I don’t expect you have a “ductulator”, but if you did you’ll find you either need a very high static pressure fan that would be so powerful that its suction would collapse your duct, or you’ll realise that your 5” (or was it 4”) duct is undersized (as resistance at that velocity exponentially increases beyond 100Pa/m). So, to slow that air velocity you really need to upside the duct to a 8”, and the you have a more reasonable 15Pa/m (still high, but keep the duct to just a few meters).
The fan will now make noise as well as the car, so if you add an 8” acoustic attenuator before and after the fan that will add around 50Pa each, and if you install and external grille, you’ll have an extra 30-50Pa.
Tallying up the static resistance pressure for 5m of duct, attenuators and grille will be at least 225Pa… Thus, 500l/s @ 225Pa centrifugal fan (blower)
So for cheap he can get a Infinity cloud 8" blower for around 160$
Nerd alert!!! 🚨

I'm going to believe you because there are words in there that sound made up by you sound so serious. Lol

That first dyno graph is the funniest thing I've ever seen.
Funniest? In all your life??? Sure?

@@karlnavidubalde9197 bro triggered over a comment 😂
@@karlnavidubalde9197you depressed bro?
@@karlnavidubalde9197 yea shit was funny asf
Bro, the dollar tree box fan on the front of the mid engine car gave me life. 😂
I love you guys.
Hey there! Glad to see you watch Gingium like the rest of us cultured swine.
you usually put the fan on the side where the radiator is. intake temps are important, but not as important as coolant temp
wow
@@StanleyKubick1 oh I’m aware. I was just more concerned with the size of the fan, but I also didn’t realize the radiator was up front on the Beat.
Take the rollers out of that dyno and ask a machine shop to put a good quality knurl on them, that will help tremendously with the grip as I noticed the rollers are smooth. The other piece of advice I have is to use double wall tubing on the section of the exhaust that goes through the wall. You do not want the heat from all that exhaust to set the wall on fire.
good point.......some exhaust wrap inside the wall maybe a good idea!
In-house tuning? Gingium race team is gunning straight for the top
Dude now ging can take better.time management on his cars as he doesn't need to get a dyno day or any of that stuff.
Remember the debacle with the Mazda truck? That shit was funny but man did it suck cause Ging had to rush a lil
Yony? Jony? however you spell it, is so smart. Bro has serious Rob Dahm genius energy. I love him.
Haha yes Yianni is the goat
Not that great of a person to compare him too bruh

@@ryanolson6794 a lot of things
@@CamiM305 okay..?
i did not have "Gingnasium becoming a full service everything shop" on my 2024 Bingo card.
Nor did I 😂
dyno sauce aka spray glue does the trick
also having a bar / eyes close to the dyno that the straps go under to adjust the direction of the tention helps loads to pull the back end down
Making so much power that the graph started doing backflips on the first pull
@Gingium they make inline duct fans that are designed to attach to the dryer ducting and pull air through the system. that plus a dryer vent cap with the auto closing baffles/ shutters would insure you don't get any critters crawling into your building, also as others have said, wrap the exhaust, and try to route it so you can put a cover over it to prevent burns. burning a foot or an arm is NOT a fun way to learn about a hot metal surface. I am so proud you guys are DIY'ing so successfully.
My old shop had an exhaust extraction system. First, you'll want to find some crush proof "exhaust hose", made specifically for this application. Price depends highly on the heat resistance you need for your application, and you can buy it in various diameters. Second, an effective extraction system needs a fan to actually pull the exhaust through the system. Something that pushes at least 300 CFM. If you have this, you won't need to worry about making the hose fit the tip of the car as it'll suck it straight out as long as it fits loosely over the exhaust tip. I imagine you could place a fan on the ground outside after the muffler with some form of ducting to it, so it doesn't matter how large it is, as long as it can withstand the temperature. You also might want to look into local laws for exhaust extraction to make sure you don't get hit with a fine for some reason.
I've seen some people recommend a furnace blower, seems like a good idea
i was gonna say, you need an extractor.. and you may want to look for a BIG one otherwise you will still have fumes in the garage. ask me how i know 🙂 been fiddling with his a lot when i got my first dyno. Also if you ''extend'' the exhaust like it is now this might affect how the engine performs wich is not ideal. Have to say very cool project and what a superb asset for the workshop, Having a dyno is one of the best things when doing car and bike modifications! Thumbs up!
Maybe building a platform would be the move? That angle is going to be rough on really low cars even with the ramps.
Molly is pretty darn low and she fit on the dyno without any issues. a platform would just take up way to much space.
Best thing to do is bury it. That's kinda hard to do when you don't own the building. I like how some shops position they dyno right behind a drive on ramp hoist. Makes it easy to get the car on the dyno. And you also now have a very useful drive on hoist. That's what I would be looking into. But it's also about space and money. Neither of which are none of my concern or anyone's else's for that matter. It only matters to one man.
@@_Gingium_ to me it seems like the wheel spin might be slightly caused by the car squatting and bottoming out. Seemed like it was really close to the dyno when you showed it on camera.
You could also just extend the ramps out farther causing less of an angle, suspension will load up on a dyno and can squat the car quite a bit, but really nice job on your ridiculously cheap dyno 👍💪
"are you a car guy?"
"Bro, my shop has an exhaust"
you need to beef up those intake fans, Gale banks has some great vids on their dyno fan setup
You're going to want an inline fan for that exhaust. I've seen small engines destroyed from doing the same thing. Also get a carbon monoxide sensor while you're at it.
He mentioned he has a monoxide detector at 16:54
That exhaust "pipe" is going to get pretty hot. Make sure to insulate it so it doesn't catch the wall OSB on fire. (and doesn't burn people as they walk past it).
Probably a good idea to make it go up and over, just so it isn't in the way of people walking around.
I would put the muffler inside and I would also use a fan to draw the air outside.
Use wood stove double insulated in the wall.
Rated to 1400f i believe
Used to work at tractor supply so i was thinking of solutions that would work from that lol
he should just turn the dyno 180° and just have the exhaust pipe tubes run along the floor out the garage door
hopefully his building doens't end up like drift games building :(
@@benjamin8558 that's where it will be for FWD cars.
@14:56 you need a small, durable fan to fit in the mount on the wall, to provide adequate suction & yes a longer hose from the wall would DEFINITELY be a good thing!!😅🥃
That clearance to combustible through the wall seems a little too close, would look into properly insulating the portion that goes through that wall.
This is a big up for the shop! You can use a 55 gal drum for a very effective muffler outside. Please be careful about your wall catching on fire too!
That outdoor muffler is the coolest idea ever dude. This is such a steal and I'm assuming that you're gonna get a huge productivity boost since you don't have to wait for dyno appointments anymore. Soooo fucking hype to see you tune the first car on it!
You need to build an exhaust vent that clamps on the inside diameter of the exhaust tube. That way you can have the clamp adjust out and not worrh about diameter sizes. Also a inline fan would do wonders to that vent.
For our dyno, we use CRC belt conditioner. Get the car started, and let it run in first, and just hit belt conditioner on the roller and tire, and youll hear the difference.
Im watching your shop and videos get better and better every week. Keep on keeping’ on!
Always love new shop and car content from you. I’m a flight attendant and absolutely love watching your videos on my flights ( when not actively working of course).
Love the external muffler. Nice and quiet, but also the quality of the sound is lovely.
Killing it man, Your shop just keeps getting better.
Hey you should put some wire mesh screen on the outside muffler. 😁
Your videos have been just a blast to watch lately, just getting better and better!
Make sure you put some type of cage/grille on that exhaust so animals dont get in. Might just want a solid cap or a tractor flap so bugs dont get in either when you aren't using it
Great timing on the video I've been waiting all week for
Might want to have a way to block off the outlet for the exhaust when it ain’t in use that way bugs and birds can’t get into the shop
U should put a stack of old tires around the muffler outside, will cancel more sound out, saw it on sammits channel 🤙🏻
bro ive only watched two video's of yours and everything you do is so smart and im inspired to watch more and you've earned a sub with notifications from me!
When you have done the extraction of exhaust like some of the commentera proposed you seriously need to upgrade the cooling ALOT. To even simulate really slow road driving it takes a massive amount of flow. Great work, very reasonable way to get your own dyno!
Should put an exhaust fan on the end of the muffler, help pull the fumes from the tip to the outside reduce potential back pressure effects (if any) and reduce the fumes leaking too
when that exaust muffler outsider the building actually worked made me so happy haha! so stoked on the dyno and happy for you gingium!
I always love the background beats and nice shots. Bro never misses
Caleb sure does love his eggshell black🖤
For the exhaust here ya go (dyno tech from years back):
- 1x Furnace Blower Fan (check grainger)
- Old Muffler from Bulldozer or something similar (looks like a goofy chimney) from salvage yard.
- 2-3x Flexible Exhaust sections connected to by hard pipe or stainless flex pipe.
On the end that goes to the car exhaust, fabricate a the end of a Flexible exhaust to look like a Christmas tree holder with thumb screws., other end make flexible enough to rest most of it's weight on the ground free of debris or wires.
On the wall side the I like to muffle (with the dozer/construction equip muffler) then put the fan after words to suck it thru and to reduce the heat fan sees and as post muffler of sort, finishing off with a "tractor cap" on the outside pipe.
Good tips, furnace blowers are relatively inexpensive
That 4.7 lifter tick holy shit
So sick old Dyno. Painted.. exhausted outside quietly very nice!
this is one of this coolest things ive seen in a long time. I love projects like this... to mitigate wheel slip you might try roughing up the rollers with low grit sandpaper... ultimately they need some actual knurling to handle higher power levels
That's bloody brilliant! Nice work gents!
this is one of the cleanest jobs i've seen, goes well with the rest of the garage. aspiring
gingium really making moves i love the shop progression!!
Mufflers are restrictions. Hell, the 'extended exhaust' is technically robbing just a tiny bit of hp
Boosted John cameo was cool to see
Nice when a plan comes together! 🙌
A lot of tuners use upholstering adhesive to keep the tires from spinning granted that's supposedly the amateur method. More professional tuners will use a track prep glue. I'm sure you'll find something lol.
Man no way haha as if you got a dyno for $300 dollars, absolutely ace how far you’ve come and so much yet to, here’s to many happy hours spent on the dyno brother 👌
you and Yianni make a great team!
That's legit hysterical. Love it.
congrats and well done, lets see the fit on there.
Damn. This is a game changer. Never thought id see gingium set up his own Dyno. Hell ya. Have some fun.
Take a look at crushproof exhaust hoses. Multiple shops I've worked in have had them for their exhaust systems. They're rubber so I'm not 100% sure how they would react to the heat from full dyne pulls but they're pretty heavy duty so definitely worth checking out. They also have a bunch of adapters and such for various exhaust sizes
Boosted John?!?! I love this!
Ive seen shops use heavy duty corrigated rubber exhaust hoses with wide mouth tips on them that can attach to your setup. That metal hose end could potentially scratch up exhaust tips.
Dude this is too awesome and I am so entirely jealous hahaha. It's my dream to have a dyno. Keep up the awesome work!
You can always start with dynoroad, seen they are pretty damn close. 1hp or less difference from dyno.
@@Morteexx True, but not useful for tuning so much. 🥲 Thanks!
Looks like an amazing setup for “cheap”. You’ll need to think about the setup if you want to do FWD vehicles for the exhaust/fan etc
Fwd will go out the door?
Love this kind of diy solution
SAMMIT did an exterior muffler for his shop out of tires, burying the outlet of the exhaust into several tires. May be worth a shot using some old tires to knock some more of the noise down.
It’s good to see Molly, hope you do more videos in the future with her for what you built her for
Put an extractor fan inside the dyno exhaust, and also make the pipe go up and exit above the roof of the building. It will be miles quieter this way
Seen this man come all the way from a house garage all the way here. Inspiring
Were the miata pinch welds bottoming out on the dyno when strapped down? It might have spun because the force from the straps wouldnt be going into tires.
You could also put on a set of knurled rollers instead of those smooth painted ones, that would GREATLY improve the grip of the dyno.
Water is the best baffle, route the exhaust into a big bucket of water outside with a loop in it to stop the water coming through, similar to a toilet. Zero fumes and no sound outside
and a huge exhaust restriction!
nice Dyno, The metalrules need def. a modification, and placing the car Horizontal and strap it down in the middle will also help a lot. It is commonly used Technik at high horspower. You will have a lot of fun in the future wit the Dyno :D
You could also put some bed liner(As a paint) on the roller to make them more grippy
They make a rubber hose thats usually used to vent exhaust out through garage doors. I believe you can get it in 4" diameter. You can also get adaptors for the exhaust pipes from the same company. Or at least you uesed to be able too.
The D&D is stupid loud. Rubber exhaust hose will quiet things down vs the dryer vent hose. Do you want a muffler (backpressure) vs sound box of some type.
The fan set up for the dyno matches that car perfectly
I definitely would put a sign next to the outside shop exhaust with a text 'hot surface, do not touch!' Or something. Just to be sure you do not get in some kind of lawsuit
Put an industrial extractor fan on the SS pipe on the wall amd turn it on whenever theres a car on the dyno, so it forces exhaust out instead of relying only on engine flow....
Best UA-cam channel. 💪
That's awesome! Not too many people can say they have their own dyno. I wonder if having the exhaust connected directly affects the car's performance in any way, wonder if it would be best to keep the pipe separate but put an inline exhaust fan in the pipe. Although hooking it straight does help a lot for noise. The way that outside exhaust worked is actually quite incredible, was not expecting it to work that well.
I'd make sure you have some kind of spark arrestor coming out if that building since you're right next to your propane tank and fuel oil tank
Needa have the exhaust turn up on the outside. The heated exhaust wants to rise. Just make sure to put one of those Lil roof things on it so rain dont get in
Was that a Dino graph or Caleb’s best ever etch-a-sketch drawing? 😂 honestly I love Caleb’s approach to these projects, just buckle up and get it done! Inspiring 👍🏼👍🏼
broll of the d rings 😂
That's awesome! Maybe try some skateboard grip tape for the rollers 🤷🏻♂
Hell if anything, you have a cheap option for break in periods as well and simple road tuning and even first drives and bring the load in gradually. So even if/when you get a bigger "real" dyno, you can still have this next to it for those simple first steps and testing and leave the main dyno for the big jobs.
I wish I could use a mustang dyno but I have a Camaro 😢
😂
yeah it sucks that they made dynos for only one model of car. Kinda tough to book a dyno session
Same:(
Hi great video,
Don't forget when making the ex pipe you need to make it so you can fit a external O2 Sensor, in case any cars you are running have not got one built in, you do need to monitor the o2 mixture when under load,,
Also Trevor from motion autotv is using the same dyno controller, it does seem like your mate is doing well with that,
Good luck from the United Kingdom,
Dave
That duct needs to be double the size with a doubled the size funel on the end to catch the exhaust because doing what your doing will cause readings to be off for sure. Ask any other dyno operators about this.
This is so coo, very motivating
You can get rubber exhaust hose that’s meant for what your doing
You should really add some gussets to those ramp holders, that's a lot of shear force to put in a very small area and it would suck to have one snap off while you're backing a car up the ramp.
dont forget about cars with dual exhaust tips
You could also maybe try a fan so it’s sucking the exhaust while you’re making a pull. I don’t know if that would affect the pull itself. Great video either way.
If you are super concerned about EGT on the exhaust removal system for the Dino make a augmenter tube *used on airplane exhaust* it will pull fresh air in through the tube reducing the actual EGT and you would get positive displacement. So no back-flow of exhaust. As for the fan require for the job to pull air through idk
Add a fan to create section and increase the efficiency it gets pulled out. With no fan you maybe restricting power I think too
Major acquisition. This, plus the shop expansion, is going to level up your work and the channel.
Gingium with a dyno before GTA VI is crazy 👀
euu lighting is great, meanwhile runing some home depot fan in fron of the car :D
you're so close to being able to drive the building!
lol the fans I’m assuming you’ll get a real air mover in the future but for the exhaust pipe the shop I worked at we used a 4inch heavy duty rubber exhaust venting hose. That might work with your set up and also help with even more sound reduction. Also be careful with the heat in the wall ports.
to stop wheel spinning on the dyno use carpet spray adhesive stop the wheels spinning on the dyno we use to have that issue its like magic just makes them grip try it out
Remote mount exhaust fan. 1,500-2,000cfm should be plenty. Kitchens use them for the exhaust. If you go out the roof the noise will be broadcasted vertical instead of horizontal.
I think it only has to be like 300 cfm, but I'm not sure. Going through the roof's a good idea, though
you've a lot of faith in that angle holding up the ramps
