Final Prep & Changes Before Dyno Day (Rebirth Ep44)

[@glenjohnson5809]

I made my ducting out of cardboard then transferred it to aluminum. Works great. I call it CAD (cardboard aided design).

[@fila1445]

Glen Johnson nope Bad obsession motorsport called it CAD first

[@Krautastic]

He didn't say he called it CAD first. Hackaday and MotoIQ used the term in different articles years ago, and honestly, there's probably some disgruntled machinist cleaning off his bridgeport somewhere that used the term 50 years ago.

[@StoltzSTS]

LEAVE ME ALONE MOM, GREG IS ON

[@1188clean]

Eric Stoltz for me its leave me alone wife, always trying to tell me something when im watching KZbin

[@adogthebeast]

When you’ve been watching for a solid 6 months and just now realize that it’s Greg and not Craig....🙃

[@magnetic0314]

austin d probably doesn't help that Americans pronounce Craig as "Creg", instead of how it's spelled...

[@destin6041]

She will hold together no worries man. Stoked to see the dyno video and some pulls on higher boost!

[@LMEngineering]

The day prior to the Dyno visit is nerve-wracking....but worth it. Just think positive, a lot of the engines which blow up on the Dyno are either because of pushing the limits (because you're a risk taker) or from poor workmanship. You put quality time and parts into this so you did it right. Even if something happens it's not on you, you tried and also helped out the global Miata community as well if not better than how my other love, Honda products are documented. Good luck tomorrow, but you won't need it. It's hp/tq # time

[@DBatty]

We had cooling/misfire issues. A proper boxing in of the radiator helped allot! Excited to see your results. Great build.

[@madmiata1887]

Good to know!

[@simonsen686jeremy]

I cant wait to see the numbers. This must be gratifying getting to this stage with your car. Keep up the hardwork, i love watching your videos and continue to learn from you so thanks too

[@FlabbyTheJuice]

Hey Greg just wanna thank you for all your videos they have been an inspiration and always motivated me to finish my turbo build . Im making 200hp and 186tq thanks to good old toby down at advanced engine dynamics this last sat 12-16-17. He told me he was expecting you soon! We are all thankful for your channel, great entertainment with a good education in car modding!

[@TheCarPassionChannel]

+FlabbyTheJuice Awesome man!!!

[@setra23]

Nothing wrong with a bit of CAD (cardboard aided design). Fans of certain 4wd Mini should get that ;)

[@jimidgaffigan8731]

Greg's shooting and editing is really good at this point, good luck man!

[@sectioneightgaming4086]

Good idea with the cardboard template,brendan from beavis motorsport made a similar style plate out of aluminum for his turbo track car, keep up the good work mate

[@lpruler1]

Dude! Love your style! Cardboard engineering ftw!

[@okisub]

So excited to see the results. But Greg, don't rush to upload a video. Go and enjoy the hard work for yourself first!

[@BillyRS]

I would've thought you'd need an oil cooler if you plan to do multiple runs on the dyno. Can't wait to finally see the numbers, it's been a long time coming!!

[@Jamiebob9771]

4:00 mark. Love your drill press.

[@mm6705]

Remove the shrouding in the mouth of the grill on the sides of the intercooler, this is eliminating air that would otherwise travel past the intercooler and through the radiator. Duct along the sides of both ic and rad, pretend they are one unit, maximizing air through both. Without proper hood venting, (listed below) you are just pressurizing the engine bay with stagnant hot air. Are you using any antifreeze? maybe try a lower percentage concentration. 100% distilled water cools the best, but will obviously destroy parts if you park in freezing weather. What temp is megasquirt turning the fans on? Try turning them on at a lower temp, and turning them off at 30mph. What fans are you using? Dual shrouded oem fans or shrouded SPAL fans are the only quality options. What radiator are you using? 949 supermiata crossflow or Trackspeed dual core are the ONLY effective radiators for our cars. (unless you have a full custom tube frame race car) Did you use the 99-00 headgasket with your vvt engine? this is necessary with the coolant reroute. (also dont use the spring they include with the m-tuned reroute) Doyou have R theory or Singular hood vents? These are the only vents on the market that work for a stock bodied miata. Thats all I can think of, man, hope that helps.

[@Krautastic]

I have a civic half radiator on my 227whp miata and I have no cooling issues. Coolant reroute and ducted. I also don't have an obnoxiously large intercooler in front of it. I have an obnoxiously large intercooler *next* to it. But what you're saying is the normally accepted truth on these cars.

[@thebestempty]

Someone got a slider for their camera lol.

[@testacorsa1]

Hey Greg. If cooling continues to be an issue, I suggest that you first of all get a thermostat with a larger and wider opening (like the superstat), to have as much flow as possible. Another, and a bit more involving mod would be to install a ball valve on the heater core, as the coolant running through that never sees the radiator, and just get hotter and hotter, and just runs back to the water pump inlet (as I'm sure you know). It does not heat anything as such, but it wastes important flow for nothing. If you install a ball valve, then it's important to not close it completely, to maintain a little flow, as the coolant could boil, because it's heated by the manifold/turbo. Best solution would be a mini reroute of that return, to run shy of the turbo. If you do that, you can shut the ball valve completely to the heater core, as long as you remember to hack off the bleeder on the thermostat like you did in this video, to have some flow past the thermostat to help it open at the right temp. P.S love the build and your channel.

[@testacorsa1]

Just read that you don't have a oil coller in the comments. If that is the case, then get one of those - stat ;)

[@Marks-Garage]

Awesome video. I had mishimoto fans on my S2000 and they are crap in terms of airflow. Especially when you stick an intercooler core in front of them. When i supercharged my car i changed the intank filter for the same reason you did. I cant see the point of a fancy fuel system if you leave a knackered fuel filter in their restricting flow. Hope it goes well on the dyno!

[@daleabono3616]

The tips you shared here are awesome, Greg. Thank you!!

[@redlineriders2695]

The outro is so satisfying now! Great video as always can’t wait for the next one

[@glukan1]

Can't wait for the numbers

[@natemorris535]

Best video to wake up to!

[@wansto]

Love your posts, dedication to the end. Thank you

[@mattgiles4980]

@4:00 what a nice vise for drilling! props! ( side note love the kicks )

[@miatau8359]

I was thinking of putting the stock front bumper guard to get more flow under the radiator too or cut out some aluminum but i think that cardboard box would be just as good.

[@danloosmore8099]

An electric fan is just for when you get stuck in traffic, PUT A FRIGGIN OIL COOLER ON IT!!!

[@TheCarPassionChannel]

+Dan Loosmore An oil cooler should not be necessary for cruising on the highway. If I discover that I need one for hard running, I can add it later.

[@FiveFiveGarage]

When are you going to start selling that cardboard ducting kit? I need it for the street cred.

[@Shwalker07]

Awesome. Those dyno numbers are going to be great!!!

[@Crispyrod]

God damn man! This is legit! Love the vids love content, this is a super underrated channel

[@bilbobaggins7074]

Get a Hawley Performance reroute. Locates thermostat on back of head instead of through a long hose.

[@adizzmal]

I am addicted to Blipshift shirts, as well.

[@2nrd672]

LRB UNDERTRAY! DO IT!

[@slyfoxmartin5693]

Good luck with the dyno pulls tomorrow....always a little nerv racking. She'll be fine though you do solid work!

[@Seandoestech]

Nice! I like the placement of that IAT - sweet spot, no soakage. Man looks so clean - be nice to it on the dyno :)

[@ExhaustedOfficial]

Looking forward to seeing her on the dyno!

[@Nebbia_affaraccimiei]

can't waaaait

[@AllMyDaysFeelTheSame]

I’ve heard endless stories about these widebands failing after a week, do they replace them for free? Because I’ve heard AEM and innovate doing the same thing.

[@mattwiser7982]

You should get an lrb speed under-tray. I noticed a big difference in cooling when I installed mine. Unfortunately the side panels don't fit with IC piping though...

[@NoGrip]

Not Snapsquad, just live on BeardTube

[@jessieortiz7277]

Best of luck Greg!!!

[@counti41]

Use a lower temp thermostat. 180* or slightly lower.

[@nicholas0142003]

Thank you for the updates! Love the videos you upload. Just wondering if we can get some longer ones down the road?

[@Thatkswappedek]

Brazzers has to wait

[@tinkerscustom9568]

Greg, how do you keep your hair so perfect when you are under a car? I get near the car and my hair explodes into a mess lol. I really like the new way you took the shots for pouring the oil, great stuff man! Can't wait to see the Dyno info!

[@HotboiEngineering]

You should get an LRB speed undertray. That will solve all your underchassis air ducting issues.

[@markuscb220]

I was watching initial d but when i saw this video popping up i had to watch it

[@TheBreakfastClb]

Snap squad 🤘

[@Duke2387]

ITS TIME!!! ❤️

[@sickgnarsty_]

Snap squad wya

[@Pleumel]

good luck mate!

[@chincchongcho]

Where did you get that shirt from?

[@3rdpartyU5er]

Dont take it personally but I hate the fact that people drill a hole to piping that has strength of 1 or 2 millimeters and then proceed to make "threads" into it and then "securing" it with some rtv. Remember that the pipe is also curved so the hole is not even. Regards the man that has seen so many leaking turbo oil returns when the tuner boi figured out that he cant mig weld the oil pan because its not steel.

[@ArmstrongRacing]

I thought E85 deteriorates paper filters, check out the Golan filters

[@markproper9791]

That shirt is awesome!, where did you get it?

[@JustKyzuuh]

Blipshift I believe

Thanks mate

[@Ch0k0TB]

Good luck on the dyno! :)

[@steadfastdriven4472]

I know this works on classic chevys and fords but maybe running a super coolant would help.

[@madmiata1887]

Curious on your ducting results after some hard driving!!

[@Evan8D]

Thank you

[@jamesflores9456]

the fuel filter was filled with charcoal 85% sure

[@stevesanchez801]

I hope i get my miata soon 😭

[@Bbeavis]

good lord that cardboard undertray....

[@Mulch5640]

You've got it templated, now put a layer of fibreglass over the cardboard duct and call it a day

[@zzzzaaattt12321]

Where did you get that shirt!?

[@TheCarPassionChannel]

+Zachary Esquivel Blipshift!

[@Willowfiasco]

4:12 is that an intake manifold stud missing a nut?

[@MrPurestock63]

Yeeeessss!!!

[@tehpillemannerator]

MX gonna give it to ya

[@dil6969]

Good luck Greg! Your channel is a shining beacon in the land of slow, naturally-aspirated Miatas. When time and money permit, I will do the same with mine and your channel will be a huge help during the process.

[@El_Chompo]

coming along very nicely greg. can't wait to see her chooch.

[@michaelmilberger9013]

I TOLD YOU IT WOULD HEATSOAK DURING THE LIVESTREAM

[@garrett6422]

It looks like you got a slider for some sick shots?

[@wenbodong5717]

so... where can I buy your t-shirt? I like this one and I think you also have a dead fish one...

[@TheCarPassionChannel]

+董文博 Blipshift, and the Jelly Fish shirt is from Julian Smith look him up on KZbin :)

[@jakeguitarbass7209]

Loving the satisfying sex music 😂 The cardboard covering is very creative . Can’t wait for the next video 👍🏻

[@blueml08]

Two days without a new video... did you blow up your engine again ?

[@FANTAZ3RO]

dude.. that shirt. please tell me where you got it from

[@looolcom]

Grig, whats your intake brand?

[@alikengi17]

is that your own custom shirt?

[@derekmartin3585]

Where did u get the shirt

[@vkotis]

Love the shirt!

[@J3n555]

Nice shots! Are you using a sliderail for the camera?

[@thicknick734]

that pour was sploogeworthy

[@Nasonix2]

3 WHOLE Days ago!?!!! Where tha dyno footage?! :|

[@Likethetacosauce]

If anyone needs those pigtails for the iat sensor lmk, I can get plenty of em for cheap.

[@オッさんタイプXの日産に乗る]

yeah peace out W199@

[@rogercrier]

Good luck, not that you should need it with your quality prep

[@FeyFox]

Where can I get this shirt?!?!??!?!?

[@TheCarPassionChannel]

+Fey Fox Blipshift!

[@FeyFox]

fuck its already sold out...man I would have killed for that shirt as it sadly reflects my life.... :D

[@E30ShedSkid]

Any guesses for dyno day numbers?

[@testacorsa1]

I'm guessing the 300whp is still a goal, as the old engine just fell short of that.

[@E30ShedSkid]

My guess is 415whp

[@xmanguy94]

yay.

[@LongLiveTacoTV]

What soldering iron is that?

[@nickiwen2715]

LongLiveTacoTV probably just a butane one. They are all over the place

[@TheCarPassionChannel]

Power Probe

[@990diego1]

Yay

[@mathiasmang848]

Man that fuel rail is molesting me everytime I see it. Damn I need one of those.

[@wea619]

hi, does your block have oil jet for piston cooling on the bottom?

[@TheCarPassionChannel]

wea ridzwea Yes

[@wea619]

if i'm going for 3++hp, do you think i have to install oil jet?

[@TheCarPassionChannel]

wea ridzwea They're stock

[@wea619]

Oppss...sorry..youve inspired me for my mitsubishi 4g92...btw tq for the reply....great vid

[@adrianclavijo666]

Is that the 1.8l miata’s engine??

[@aaron_z3383]

Got to hop on the waterless coolant bandwagon

[@brummiescot]

What's going on with facial hair. Sporting the wolverine look lol

[@saucymiata525]

Snap squad

[@483972]

I am really curious into what could cause your overheating issues man .... I hope you wont get limited on the dyno because your coolant will start boiling much before knock :(

[@NGWrenchin]

Miatas are notorious for overheating stock, and he has a big ass turbo now. Pretty standard even with his upgrades

[@483972]

ncsugray90 he has re-route , older models headgasket , big radiator 2 fans... And she heats up without boost... How stock is thwt to you?

[@NGWrenchin]

I didn't say he was stock. I said stock cars have overheating problems and his is producing/retaining quite a bit more heat than a stock car, even when not in boost, so its not surprising he is having overheating issues even with his upgrades. Its why lots of people chose to engine swap Miatas if they are going to be hardcore track cars rather than boosting them. His ducting will certainly help but he will likely need to go with hood louvers as well. Not shitting on his car by any means, its an incredible build, and I am super jealous. This channel is part of the reason I bought my Miata and I plan to use a lot of his tips when I turbo it eventually

[@483972]

well .. i got no re'route , 87C thermostat , 1 fan , mishimoto radiator , 12 psi of boost .. and she runs always at 88-90 ... when pushing her hard she goes to 95-97 ... never seen 100C ... and most important :) ... I never turn on the heater ... this is why I was finding weird the thing that Greg's build was overheating..

[@NGWrenchin]

What are the ambient temps in your area? That would have a pretty big affect on how well the car can cool itself

[@swat1229]

But Greg isn’t that sensor gonna be a restriction limiting your maximum horsepower capabilities???? Nah I’m just kidding. Love the cardboard, idc if you do track days with it if it works.

[@martin051199]

you where asking why not do it in cardboard well maybe the cardboard will take fire ?

[@testacorsa1]

It's just coolant and inlet air temperatures that the cardboard will see, and not exhaust or turbo. It should be fine :)
