heat from turbos
|
Wed, 23 February 2005 10:32

I have done a search.
I would like to know how far away there turbos are mounted from other important parts of the car? And pics detailing if possible.
My dilemna is that my turbo is very close to my brake master cylinder. This is not the best pic of it but it is very close, about 2cm.
I was planning on using a metal heat shield with bonnet heat insulation on one side of it going from the firewall through to the front of the turbo. And another shield coming off the turbo heat shield and directing air flow out the bottom of engine bay. I also have one of the pipes there to duct air along the heat shield between shield and master cylinder.
The dump pipe was going to be HPC coated and exhaust wrapped also.
My mechanic has said that he thinks the turbo will have to be moved from where it is using a wedge style thing welded to the flange. The only problem with that is redoing intercooler piping and making sure that it still fits under the bonnet. It is VERY close right now which is the reason why I now have a bonnet scoop.
So any opinions would be appreciated.
Thanks
Chris

i have seen dumps coming off big T4 turbos with about 10cm of room with no probs, but he had a heat sheild that went AROUND the sides and back of the turbo, and exh wrapping

yes i can look it up for you
<ummmmmmmm> ok here it is :
qld code of practice light motor vehicles :
super/turbo installation code LA3 :
2.2 associated modifications :
2.2.1 :
all fuel, brake and electrical components which are
located in close proximity to the super/turbo charger,
must be shielded to prevent exessive heat affecting
performance or saftey of these components.
check list :
LA3 :
general :
4.1 :
are all fuel, brake and electrical components
protected from exessive heat.
yes / no
also
engine substitution code LA1 :
general requirements :
2.5 :
fuel lines must be well clear of the exhaust system and
turbo (where fitted)
2.6 :
adaqaute protection from exessive heat should be provided
for all hoses, electrical harnessses, rubber and plastic
components

yep that is what I was planning on. As well as another one that I was talking about.
And thanks Nolan. Now if only I could drive the thing!

thanks Styler for that info. However, I was referring to the actual real life practice of heat shielding. The legalities are very broad. I just want to make sure that my brake fluid won't boil. Anyone know what temp it would boil at?

So there's no exact measure that they have to be?
my fuel lines are about 4 cms away from my turbo which I think is pretty darn close. I was thinking of a sheet of asbestos type material behind a stainless heat shield that's not attached to the turbo/engine. I'm really hoping that will be enough as I cannot move the turbo further away even with a different manifold

The compressor housing of my rear turbo is about 5mm from the clutch master cylinder. Two years later, not a single problem.

Norbie: doesn’t the turbine housing get considerable hotter than the compressor housing? 5mm is not very far at all though! I haven’t measured the distance with mine but the bleed nipple that comes off the master cylinder is actually between the front and rear of the turbo so it is very close.
The heat shield on the turbo has also been cut and folded to create another barrier and deflect heat backwards.
Manmx83: thanks for that info. Mate. Also, I will have an enclosure around my filter but that is secondary importance at the moment J
With any luck, my dad is going to get a better pic this arvo so you guys can see what I mean.
Thanks
Chris

The jza70's (maybe ma70-7mgte's too) have a metal "heat shield" that folds around the brake/clutch master cylinders. Perhaps an idea for your car too?
Shielding on the turbo and on the master cylinder as well? You could paint the outside of the master cylinder shield with high temp bright Aluminium for extra heat reflectivity. Of course a coating based on IRR (infra red reflective) pigments would be better 
manmx83 is right too - the best airflow is gained by generating a vaccum that sucks air through the engine bay and a lot of scoops/vents/speed holes interfere with this.

I'd imagine plenty of metal shielding and insulation would help. HPC coated pipework, the wrapped around metal shield for the brakes, and a way for air to flow around all these areas to remove the heat and prevent it building up too much!
That engine looks HOT!

I got the same problem. A quick fix. Remote master cylinder reservoir mounting. The master cylinder itself will be ok, but the reservoir will need moving. That's what I'm doing with mine. It cooks the shit out of the brake fluid otherwise.

Chris,
Looking at what you have there id definitely make another shield covering the master cylinder. I think it would also be a good idea to hpc the dump or wrap it in insulation. If you have had to put a scoop in you may want to watch out for the bonnet paint in that region too.

thanks guys.
well the turbo has now been slightly moved. I haven't had the chance to see it yet.
I was looking at a turbo bag but I don't really like the idea of keeping the heat in there as that is what will kill the turbos in the long run. I want it to get out and then out of the engine bay.
Skip: that is exactly what I had planned

even tho the compressor side is the 'cold' sideof the turbo, it still gets very hot. my K&N pod literally melted off, i only noticed when i went to check the oil one day that it was lying on the rail.
fatmr2, im also considering the turbo bag, but they're damn exy. what did your cost? also, does anyone know the appropriate sized bag for the CT26? cause ordering it over the phone, the guy only knows generics like t04 etc.

yeah thats what i meant. my mate spent nearly $400 on his, so 200 is good but im still a tight ass
where from? is it for a t28? do you think it would fit a CT26/T4 hybrid?

Mine is for an internal wastegate t28.
Horsepower in a box.
Ask the guy if he has one for your turbo?

thanks mate. i'll sus it out tomorrow hopefully.
does it get in the way of the actuator? thats what im worried about as the turbo is mounted different to what it would be stock on mine.

the bag has a cut out fot the actuator bar that goes to the wastegate. Mine is mounted different to how it would normally go too. I havent got it on yet but ive dummy fit it and it looks like it will all work. Well im hoping so or there'll be a turbo bag for sale very soon

I have seen turbo bags for
small $230
large $290
This was at mazfix so I assume large is VERY large.
