How R you keeping the heat out of cabin?
 

Man!!! I can feel the turbo's heat radiating into the cabin !

I have a home made sheet metal heat shield over the TD04 turbo but it is sort of open on the side facing the firewall.
The DP is not covered or shielded in any way but I do have some of that shinny Mylar padded material under the carpet.

What else are you guys using that works fairly well ?

I was thinking of header tape around the DP (?)

Any ideas ?

Thanks :doh:

Make a good heat shield.

Thank you very much for posting those photos. You did a good job !
I was just looking at my heat shield. It is mostly open in the back in order to avoid the heater hoses etc.
I'm going to have to start from scratch using your approach if I try to make another one.
My DP comes down in a sharp turn from the turbo close to that metal shelf thing inside the Miata engine bay.
I might try to post pics later.

Cheers

When i remake it i'll make it out of thicker metal. The one i have now works alright and its fine but thicker metal would look better and be easier to work with since it would hold shape vs relying on the crease joints.

I don't have a metal heat shield, but I do have everything surrounded by some industrial boiler insulation. A few layers of it held on with some of the reflective "heat tape" stuff keeps everything nice and cool.

I figured if it's good enough for one of our boilers running at 1500° it's good enough for my engine bay.

What's boiler insulation and where do you buy it ?

Also, I saw a greedy heat shield like the ones Bell Engineering used to sell and they had added some type of fiberglass mat to the under side ..

All my heart comes from trans tunnel...

Yeah I have that too but not as much cause of the insulating stuff .

Found this http://www.ptpturboblankets.com/why_turbo_blankets.php

Insulation for boilers. :party:

Specifically the stuff that goes between the membrane wall and the casing.

Don't remember the name off the top of my head, but tomorrow I'll grab some and get the information. It's awesome stuff. Thin enough to be useful, and has really good insulating properties.

Maybe its just me but i dont think insulation is needed there. The fans push all the air and it hits the firewall. Having a simple heat shield acts as a guide for the air so instead of guiding it to the turbo then towards the fire wall you're guiding it through the turbo only.

Found it!

:love:


Have you checked your inner and outer shifter boots? They are a major source of heat in the cabin if they are torn.

Thanks for the info on boiler insulation !

My shifter boots could be damaged but I just don't feel the heat from there. It hits me in the face like from the gage cluster.:bang:

If you feel it in ur face is ur hood/firewall insulation ripped or something? You sure its not flowing through the vent and to your face?

Hey guys, what is the size comparison between the TD04 and other turbos like the T3 T4 etc ?
I find relatively cheap turbo blankets on line but they seem to cost more when they are listed for the TD04 :ugh:

Also, Found a square hole in my firewall where the rubber plug popped off. I had used it to run my wideband wiring. Some of the heat is coming from there.

The vents also blow a tiny amount of air when they are off.

I would think any T2 turbo blanket would work.

Thanks

I use wind. I made my Miata a convertable, then put top down and now comes the crazy part....I drive it and wind goes into the cabin.

On a moar srs thought, you can insulate your floor under the carpet. Most people don't like turbo blankets.

Yes, I use wind too but this is Florida and the AC is NG so the heat from the turbo makes the car less enjoyable :td:

My floor is already insulated - two layers of loews shinny stuff.

I added pics of how my shit looks like now. You can see the open back heat shield.
Seems like another heat shield behind this one and some header insulating tape on the down pipe will help.

Keep in mind most turbo blankets will not cover the down pipe so you'll need to make a good heat shield regardless. I say start with the heat shield and then add a turbo blanket (which will probably crumble into nothing by the end of the year)

crumble into nothing by the end of the year ???!!!! :confused:

Maybe i misspelled something. Yes it will turn hard, bridle and start to chip away piece by piece. Back when i was searching for reviews most people say they last about a year before they become useless.

Check Faefae's abortion of a thread. IIRC he went through at least 2 different blankets.

No, I believe you. I was just surprised.
It doesn't take much for me not to spend money :giggle:

Its a shame, they look quite nice.

There's a spray advertised where header tape and stuff like that is sold....:idea:

I plugged the little hole in my fire wall

Ironically it is just too darn hot in the garage to start fabricating a heat shield.
:vash:

I have the same issue and friends will ask I have the heat on in the summer until they notice it's not on. Even with the top down, and a muggy day somewhat, that heat will get to you and it'll annoy me till..........forever. I have my manifold and downpipe wrapped. I opted out of the turbo blanket for same reasons listed above. I am all for fabbing a complete heat shield one day but I think just drawing more air into the bay would help tremendously. That heat has to go somewhere no matter how you cover it. In for some real results

Drawing more air into the bay will be great for making your interior cool, but terrible for keeping your engine cool.

At one point I considered running a heavily insulated flex hose from the nose to a hole somewhere in the floor but felt that it would pick up heat regardless.

There are aircraft like vents that rotate to direct air. They come as part of the small triangular windows on the doors.

I hope to be able to better plan my approach tomorrow. Might even stop be AutoZone to pick up some header wrap or some other stuff.

This would be Crusher of 949Racing

Emphasis added for emphasis. If it works for 25hr enduro races, it will work in our peasant mobiles.

im trying to figure out why this isnt a thread about insulating the tranny tunnel...

It is ;)

finally after #30 (i didnt notice it when i posted)

Brain's mind is always on someone's tranny tunnel :giggle:

you better believe it.

I'll let you know how mine fairs. I only drive my car in the warmer months though so it won't be effected by snow and salt. It does seem a little less flexible than it was when I installed it but it's not like I am handling it at all.

I just bit the bullet and ordered a 100" x 2" roll of header wrap for the DP.

Nearly ordered the Flying Miata GRedy turbo heat shield but it really does not seem to fit my Racing Mazda dp.

Put my hand to the metal that makes up the box directly behind the firewall and it was HOT.

On the bright side - anything I do is going to make things better. :party:

And yet, no props :sad2:

(Of course, you should be thanking Emilio for sharing)

I gave you one for post #30, but -1 for this whiney bitch post :)

I should alos give poobs -1 for wrapping the header instead of insulating the things he wants to protect from heat.

Welcome to MT.net:

where the members cry in their pillows at night because they can't take a joke and take props way too seriously.

:rofl: :dealwithit:

Oh trust me, I know the props mean nothing. I just think its fun to perpetuate the myth.

Well, my brake fluid reservoir started to look like a Dali painting so I wrapped it in the said Mylar stuff and then a blue fabric piece that conveniently had Velcro on the edges. It may have been a knee running support.

Drove the Miata to a job interview today. It was HOT !!!
I tried to attach some pics of where my insulation ends under the carpet which about 3 inches from the shelf but the upload failed :vash:.
While I was down there I added some more insulation just to see (feel) what it does.
I also added some foam packing stuff to the underside of the dash by the driver’s side directly under the steering column.

Turbo heat shield is next.
:vash2:

WAT

What am I doing to the heat shield ?

I'm either extending the back of it or making another one that will attach to the firewall. :idea:

Go home Poobs, u drunk.

Heat shield maybe? :confused:

I just pulled the turbo heat shield ... It is going to be a bear to put a barrier between the DP and the stuff on the firewall.

I can see why the Flying Miata heat shield doesn't fit well with my DP :bang:

Put a heat sink on a turbo to keep the interior cool? Sounds like something hyper would propose

Nah he would put the ecu in a water cooled container cooled by the holy grail reroute on top of the manifold.

why dont you unlock the ignition timing and use the timing table...not only will your car run significantly better, increase mpgs, make more power, but it will also cut down the EGTs and stop melting your face.

ask redturbomiata about this.

Yes I failed and didn't set it back to the timing table, as a direct result we have this. Its the little things that come back and bite you in the ass later. Oddly enough it was not that hot inside the cabin.

Attachment 87413

no bro, you should keep your timing locked and just run a heat shield.

Yikes !!!! :eek:

Based on the above I think this information is appropriate


Took the turbo heat sink out yesterday and drove my son to school this morning about 1.5 miles away – a 10 minute ride
A few minutes after I parked the car in the garage back home I took temperature readings with the infra red thermometer aka laser pointer cat toy.
The turbo hot side was in the 500 plus range. The down pipe was nearly 400 degrees. The firewall shy of 200. The metal thing by the master cylinder 200 and on the surface of the 2nd top most layer of insulation under the dash it was 91 degrees. Gotta make a better heat shield.
Your mileage may vary
Note that I had to open the hood to take these readings. I expect the temperature to have dropped a lot soon as I open the hood. :hsugh:

FOR THE LOVE OF GOD, WHAT IS THIS!!!!

I can't keep reading this thread if i don't know what a turbo heat sink is...

Is it like a big hunk of aluminum with cooling fins and maybe an electric fan moulded to the turbo?

Pictures!

:rofl:

no seriously... and please read post 51 and 52.

R U guys making fun of my accent ??! :crx:

There is no turbo heat sink (that I know of) it was a typo on my part. My feeble knowledge of electronics getting in the way.

omg, please articulate you've read post #51 and taken the necessary steps to confirm this is not your issue.

I did this (except I did the entire tunnel and added a second layer in the area closest to the down pipe).

I also did this:

Attachment 239546

Ceramic coating + heatwrap + cooltec clamp on heat shield

As one can tell, I was really sick of burning my leg on the sheet metal (no carpet/insulation in my interior). I'll post the results/effectiveness once the car is running.
