Here is the article rewritten in a well-structured format:
A Little More Carefully Today, Eddie.
Eddie bashed the equipment a little more carefully today. After referencing the instructions several times, he realized that the pipe was upside down. This fitting looks ridiculous, but he guesses this is how it's supposed to be. Does it meet up? I mean, we're doing it. We're in business. It looks crazy though. So, they're just gonna keep going and move on to the other side. Get the pipe that holds the blow-off valve in and try to get the thing connected to the throttle body.
So, to get this side of the intercooler piping done, he needed to add a 3/8 NPT bung for the IAT sensor. He took this home last night and welded a little bung in. It's not super pretty, but it will work. So now, they just got to put this thing down in there. He does have to figure out one little horse for the idle air control valve, but shouldn't be a big deal.
So, let's get this on, and that's it for our intercooler piping. They've got a turbo attached to their engine. See if she fit. One second. It all links up. We are connected to our throttle body. I don't think the routing of this intercooler piping is the best. It's a little long and a little bendy, but it will get some boost into the engine. So that's pretty exciting.
Now, there's one thing left that they need to install today, and that is the blow-off valve. Eddie does it. Yeah, that one. First off, what is a blow-off valve? Well, it's basically a pressure relief valve. You know, your turbo's making a bunch of air and slinging it into your engine. But you know, that's great when you're on the throttle, but as soon as you get off the throttle and close your throttle plate, while there's a bunch of compressed air trying to run into your engine and it's hitting a wall.
So what happens then? Basically, all that compressed air has nowhere to go, and it can do significant damage to your turbo. So, you gotta make sure you have a pressure relief valve. Whether that's a blow-off valve that vents to atmosphere or one that recirculates it back into the intake track, doesn't really matter. It does the same job.
The atmospheric blow-off valve that they're going to be running is the kind that makes the most noise. So that's the good stuff. But you generally need to be running some sort of a map sensor. If you are running a MAF, it's usually a lot more difficult to run an atmosphere blow-off valve. They have a standalone ECU with a map sensor, so they're going to have no problem running an atmosphere blow-off valve, and it should sound pretty cool.
Let's look at the one that came with the kit. It doesn't weigh very much. I mean, this is a really cheap knockoff blow-off valve, but the idea is that you connect a manifold vacuum to this nipple here. And basically, anytime you shut the throttle plate, the intake manifold goes into extreme vacuum. So, as soon as this nipple sees that extreme vacuum, the valve opens and relieves all the pressure in your charge pipes.
It's really simple. It's pretty cool. And it sounds awesome. All right, so a different blow-off valve will have different flanges, which have to meet up with your intercooler piping. This is a gritty style flange, but there are a few different types. So you gotta make sure you get a blow-off valve that'll work with whatever charge piping you have, whether that's OEM or aftermarket like this.
Now we just need to get the vacuum nipple on the blow-off valve hooked up to a vacuum source at the intake manifold. I keep getting the same... (bright upbeat tune) All right, the supplied vacuum tee'd into a vacuum line. Now we've got a vacuum referenced down to our blow-off valve. So with that, their cold side is pretty much done.
The intercooler's in, all their piping is in place. They've got their holes cut, it's all installed, and they've got a blow-off valve on. There is legitimately a turbo connected to this engine now, and that's pretty exciting. So I hope you guys enjoyed this episode. I hope you learned a thing or two. Come back next week when we're going to be doing fueling on the Miata, so we can get that much closer to actually ripping this thing on the streets. Thanks for watching. Follow me on Instagram @Zachjobe and follow Donut @donutmedia. And I'll see you guys next week for part five. Goodbye.
WEBVTTKind: captionsLanguage: en- So you wanna turbo your car, classic.You wanna be a boost creep.You wanna make a bunch of cool noises,make a little extra horsepowerand make a bunch ofdudes in a parking lot,think you're cool.Trust me, I get it, but itcan seem so overwhelming.There are so many parts.How do you know what to buy?How do you know if it'sgonna work together?Sure, bolting a turbo toyour engine is sweet and all,but you gotta cool theair that it spits outbefore it gets to your engine.That is where an intercooler comes in.But how do you know howto choose an intercooler?Are there different kindsand what kind ofconsiderations should you makewhen choosing anintercooler for your setup?Well, that's what we'regonna be working on today.We're going to be working on the cold sideof our little turbo setup.We're gonna be installing our intercooler,all our intercooler chargepiping and our blow off valve.And along the way, we'lltalk about what all of it isand how all of it works.I'm Zach, and this is MoneyPit Turbo Kit part four.Let's get cooler.(upbeat music)Huge thank you to Ridge Walletfor sponsoring this week's episode.If there's anything that I've learnedover the past few weeks, it'sthat the Ridge wallet reallyis the wallet of the future.Most of you guys areprobably still using walletsthat were designed in the 90s,that's like having rolleddown windows in your car,you purists.It's durable, it can hold up to 12 cardsand even secure your cash.Not to mention, it'll saveyou from digital pickpocketswith its RFID technology.And the best part is you don'thave to wait for the futureto get one, all yougotta do is head on overto ridge.com/donut and get you one today.And if you enter codedonut, you'll get 10% off.But hurry up becausetime is of the essence.(alarm sounding)Oh God, I guess that's it for me,it's time to get back to 2077.If you thought 2020 wasrough, I got bad news.(explosion sound)(Zach makes gibberish sounds)All right, so we alreadyknow that turbo worksby using your exhaustgas to spin the turbine,which also spins the compressor,which makes a bunch of boosts,crams a bunch of air intoyour engine and makes power.But the air that comes outof the turbo is gonna be hot.and hot air is less dense,which means it carriesless oxygen than cold air.So the idea is that we cool that airthat comes out of your turbo downbefore it enters your engine,so we can make it cooler,make it more dense,make it carry more oxygen sowe can make more power baby.Well, that is what an intercooler does.Let's take off this front bumperand look at where this thing's gonna go.(upbeat music)Where's that coming (mumbles)Top of the box.- Yeah- Are we good?Hey, plenty of room.So the intercooler isgoing to go somewherein this vicinity.And basically the idea isthat one way or another,we need to get the airto go from the turbointo the intercooler andthen out the intercoolerand into the engine.So it's going to be a little bit work,but before we get into the work,let's talk about intercoolersand what the different types areand what you should be thinking aboutwhen you're looking at intercoolers.So there are a couple ofdifferent types of intercoolers.The most common of which beingthe air to air intercooler.Basically it relies on airflow to flow through it,ambient air to cool down the charge therethat's inside of it flowingthrough these tubes.This is probably whatyou're most familiar withseeing on the streetsand things like that.This is what's calleda bar in plate style.It's just in reference tothe way that it's made.It's a bunch of bars andplates welded togetherto make channels for thehot air to flow throughwith a lot of channels forcool air to flow through itand extract the heat.And then there's also tubeand fin style intercoolersthey're going to be morecommon in OEM applications.They look more like atraditional radiator.There is a style ofintercooler that is betterthan both of those atcooling your charge air.And that's a water toair style, intercooler.Basically it passes your charge airthrough a series of cooledtubes using a cooling.The problem is that they arekind of complex to install,especially if you don'thave water to air coolerfrom the factory.So like if we wanted toput a water to air set upon this car, we'd have toinstall a separate pump,a separate reservoir.We'd also have to installa radiator upfront.So it's kind of a complex setup.So for that reason, youdon't see them all the timeon the aftermarket.That's why this air to air bar and plateis probably the mostcommon thing out there.Okay, so let's actually takea good look at the intercoolerthat came with our CX racing kit.This actually looks decent.All the fins are straight.The welds look not too bad.Fin density is pretty good.Basically the more fins per inch here,the longer air will be kindof trapped in these finsand kind of the more cooling it'll do.Usually you'll have alittle bit less fin densityon the charge paths in therebecause the more fins youhave in your charge air paths,the more resistance toflow there will be in.You don't really wantmuch resistance to flowin your intercooler.You want this thing to flow really well.Otherwise you're just gonna endup stressing out your turbo.So I mean, this thing looks pretty good.This size seems about appropriatefor the horsepower we'regoing to be making.When you use the intercoolerthat's bigger than you need,you lose some pressure fromthe inlet to the outlet.That's what pressure drop is.Is the difference betweenpressure at the inletand the outlet.A good intercooler is going to havea really low pressure drop oflike one or one and a half PSIor even the lower than that.A bad pressure drop is likeanything North of three PSI.So a good intercooler won'tlose very much pressureand you won't stress out your turbo.You won't create all that extra heat.So it is all about air flow,but how do you know howmuch air would be flowingand whether or not thatworks with the intercooleryou're thinking about?there's at least one calculatorthat I know of online,where you can roughlyestimate horsepower to CFMs.Okay, so horsepower willestimate 260 at the crank.And that equals about180.44 CFMs of airflow.So now that we know that wecan go to CXRacing's websiteand look at the info they provide us.So basically what we want to do,we're going to look at thisgraph and on the Y axis,we have CFM cubic feetper minute of air flow,and on the X axis, wehave PSI of pressure drop.180 CFMs puts us just overthree quarters of one PSIof pressure drop.Now, like I said earlier,anything below oneor even one and a half is pretty good.At just over three quartersof one PSI pressure dropat our airflow, that'sactually spectacular.I hope it's true.So with all that said,I think we can go ahead andtry to hang the intercooler.They did include some brackets,so maybe it won't be too hardand maybe we won't have to trim anything.I really have no idea.There are no instructions.So,we'll find out.(upbeat tune)Well, I think we're goingto have to lose ACDsthis as it's supposed tobe this, what is this?The receiver dryer or something,whatever this tank is up here,obstructs the intercoolerfrom going where it should go.These brackets should meetup with these bolts up here,I think and they can't.I mean, this is kind of theway this sort of stuff goes.You might have to trim somestuff or remove AC altogetherto make room for stufflike big old intercoolers.Hmmm,all right AC.Damnit, it's time to come out.- Top for a time-lapse.- Yay, montage baby.(bright upbeat tune)AhhaOkay, so we got the AC removed,which actually I'm pretty excited about,freed up some room and we'vegot our intercooler hung.So now that the intercooler's there,it's time to talk aboutintercooler piping.That's pretty simple stuff.It's usually made out ofaluminum, sometimes silicone.This kit came with intercoolerpiping that is bent and cutsupposedly to fit the Miata.So we'll see how it fits,but this is something that'salso pretty easy to dowith like a DIY kit that you just geta bunch of random bendsand lengths of pipe,and then you can kind of cutit to fit your engine Bayas you need to.But the trick is you seethese raised edges here,that's a bead rolled edge.And when you're running a turboand putting a lot of pressurein your charge pipes,that bead rolled edgeis what lets the couplerand the hose clamp or a T-boneclamp really lock on thereand keep from blowing offwhen you're making boost.So if you're cutting up your own pipes,that's kind of the trickiest partis getting the bead roller on there.You can buy a tool tomake these bead rolls,but it's about like150, 200 bucks or more.But let's talk about the size of it.You might think you should choosethe biggest size you canfit because more airflow.Well, to a point that is sort of true,but if you choose anintercooler piping sizethat is too big, it's justreally ultimately more volumethat you turbo has to fillbefore you reach max boost.It just increases turbo lag.So it's important to not go overboardon your intercooler piping size,similarly, to not going toobig on your intercooler.So I think these are all two and a halfwith a smaller pipecoming out of the turbo.That's pretty common.I believe that just kind of promotes flowtowards the engine.I think that's really about all there isto talk about intercooler piping.So now, I'm going to install it.- For shorter business.- Is?- for what is it?- Oh, I see.Well, so actually, all right,so we ditched the air bagson this car a while agowhen I did the steering wheeland also the airbagmodule pooped to the bedshortly thereafter.So this airbag sensor uphere kind of lays in the wayof where the intercoolerpiping is going to go.So I'm just gonna get rid of it.(tool falls on the ground)Whatever.All right, now that's out of the way.Then we're going to have to cut a holesomewhere in this vicinity.This stuff's probablygoing to need to moveaccompanying the shaft.See...Well as expected, wedo have to drill a holeand like kind of this frame apron area.To do that, I'm going tohave to take the fender off.Hey, remember those things.All right, so after consultingthe comprehensive instructions,which consists of like a couple pictures,pretty sure we knowwhere to put the holes.So now we just got to put it.(drilling machine starts)No going back, baby.(drilling machine working)We did it.Now we just gotta paint thisbare metal, so it doesn't rust.Okay, now with a nice new hole,the first pipe connecting tothe outlet of the turbo is onand comes over out here.So now we're ready for thenext piece of the puzzle,which I think is this one.So the idea when you're setting upa intercooler piping routing,is just to make it as smooth as possibleand as short as possiblewith no unnecessary bends,just you know, to improve flowWell, so a little shortand I can't really movethe intercooler any closer this way.This is about all we've got.So you can see the pipeshitting pretty good right there.I think we might haveto do a little bashing.- Should have done it.- Nah-- You wouldn't do it.- We're gonna, we're gonna basha little more carefully today, Eddie.(bashing the equipment)All right, so afterreferencing the instructionsa few more times,I did realize this pipewas in upside down.This fitment looks ridiculous,but I guess this is howit's supposed to be.Does meet up, I mean, we're doing it.We're in business.It looks crazy though.So we're just gonna keep goingand move on to the other side,get the pipe that holdsthe blow off valve inand try to get the thingconnected to the throttle body.So to get this side of theintercooler piping donethe side from the intercoolerto the throttle body,I needed to add a three eightNPT bung for our IAT sensor.So I took this home last nightand welded a little bung in.It's not super pretty, but it will work.So now we just got to putthis thing down in there.I do have to figure out one little horsefor idle air control valve,but shouldn't be a big deal.So let's get this on,and then that's it forour intercooler piping.We've got a turbo attached to our engine.See if she fit.- One second.- It all links up.We are connected to our throttle body.I don't think that the routingof this intercooler piping is the best.It's a little long and a little bendy,but it will get someboost into the engine.So that's pretty exciting.Now there's one thing leftthat we need to
