Heat Input? What Heat Input?

Things that you notice and really wish that you hadn't!

Whilst assessing the accessibility to the top exhaust stud on the left rear cylinder, I found that the exhaust pipe and the coolant pipe coming from the coolant pump pass within 10mm of each other.

How very #$%^&* clever!!!!!!!!!!!

It is obvious that the coolant system bloke and the exhaust system bloke never got to talk to each other!

Yeah well it can get pretty damn cold in Europe so obviously the VeeDub engineers figured why not deliver the radiant heat from the exhaust pipe to the incoming cool coolant passing through the very adjacent big coolant pipe so as to assist with engine heat retention.

Fantastic use of otherwise wasted heat. Seems quite logical to me ...

I will make a heat shield after I have fixed the exhaust stud.   Anything at all will improve the situation.

lol...
you are just noticing this now ?
 
On the 1.9 waterboxer engine there's a little heat shield on the hose, the exhaust pipe is that close.
and I'm sure you notice that no other cars have their exhaust pipes and hoses this close together.
 
on the 1.9 wbxr engine with AC ....a hose goes 'though' one of the belts..
another thing you'll never see on any other brand of engine.
Hoses always go 'around' the belts.
If that AC belts gets a little loose..
it can wear right through the coolant hose there.
 
gotta luv 'em..

Les, before you disappear into the garage to design/manufacture a heat shield let me check tomorrow on mine. I am sure we effectively can use heat shield webbing as is used in

The Aviation Industry. If it works, I sure can find some to send it to you.

I’m on my own the next 3 weeks ...plenty of time to look at and rectify all those woes and faults  by design on our Syncros........

Hartmut,

Thanks for that.  

I was turning over in my mind the efficacy of an air gap heat shield versus applying insulation to the coolant pipe.

Against the air gap shield approach is that I don’t know what airflow exists at the point; air gap shielding is much more effective if there is a flow through it.

Against the insulation approach is that it is possible for the insulation to eventually heat up to the point where it is no longer insulating.

And above all that is the fact that the gap is in the order of 8mm, which doesn’t leave much working room for either an air gap shield or insulation.   I am seriously considering re-routing the coolant pipe just to get a bit more gap to the exhaust pipe.  Getting that 8mm up to even 20mm would help considerably.

In aircraft exhaust pipes are insulated by tape,  I don’t think it loses much of it’s intended purpose to shield surrounds like glass fibre from heat. It would be relatively easy to quantify with

a thermometer  (about $ 99 from Aldi or Jaycar).

You are probably right and I am probably being too exacting about the nature of the insulation.  The pipes cross at near right angles and insulating the exhaust pipe for even as little as 40/50mm would help.   I can’t quantify the heat acquisition that occurs due to the pipe proximity but it is just so silly to run a cooling pipe so close to an exhaust pipe.   And it is just inches away from the head, so the exhaust temp will be at its highest.

Is it really causing a problem or just perceived?

How about inside the head where the coolant is very close to the combustion?

That wrapping really does work well. I always loved the look of it on old race cars. The "new" thing on the block is ceramic coating. For its thickness it is amazing how it holds heat in. A race car i worked on recently had had it done and you could put your hands on the exhaust with a hot engine without getting burnt. There is a guy out castlemaine way i think that does it. I would assume sandblasting or a new exhaust would be needed. I think you can also buy it as a paint and diy. Easiest to do the wrap though couple of stainless straps and your done. Greg E

Hi Greg,

Think that you are talking Thermo – Tec EXHAUST INSULATING WRAP 2” wide. The tape is only 1.5 mm thick. I think if Les is insulating 150 mm that should be enough.

I will send him some for that to do also allowing for ¼” overlap.

But Les be warned! Your cyl. #4 will experience a scavenging effect and because of the higher velocity of the gasses passing that cyl might experience a micro increase in power!!

 

Hartmut

 

Les please forward me your mailing address for the tape

Phill,

There has to be a transfer at such proximity.   How long do you think that you could hold your hand 8mm away from the exhaust pipe while driving at 100KPH?   The point is that it is an unnecessary heat input.

The coolant inside the head is where it is designed to be and doing what it is designed to do.   The exhaust pipe nearly touching the coolant pipe is very un-clever and un-cool.

Les and all.On certain plastic,and a p/s hose,that runs right next to the extractors on my Falcon,I used a product called,Thermo Sheild by COOL IT Thermo tec Racing products.
It is a Metallic insulating adhievsive tape which has a radiant heat reflection of 2000 degres.It is designed for protection of hoses and wiring and fuel lines.
Without it and the heat from those extractors the hose would not of lasted a week.

I recently had my extractors coated by JET HOT coatings and the finish is very impressive.  It cost $225 for my T2 headers and they took care of the sand blasting as well.
They are in Victoria.
I haven't tried putting my hand near them when hot yet but they are supposed to keep heat in,
