Thermal shield for FMIC pipes

[HtwCHACtkh]

Bumping an old thread... But I just did this today to pass the weekend. The smaller pipe is normally hidden so I started on that for practice by the larger pipe I got the idea. I found it easier and neater to wrap around then snip and then over lap it with the next strip; just make sure you make the snip on the part that is not visible easily and it'll look nice. Used almost all 10m's of it.

Also, I noticed if you angle away from a bend to begin with and by the end of it'll be facing the other direction. That info helped me get it looking a little neater/even by the end of it.

i.e: if the bend is an:

L

Then if you're starting from the horizontal part, start the strip like this:

\

and once it wraps around it'll be in this direction:

I'm also painting them black to stop it from standing out so much it holds paint quite well, I was almost tempted not to because it does look pretty damn cool - like something off a space craft . The paint isn't completely done yet, I'm going to smooth it out a bit and re coat it tomorrow for a nicer finish.

I left the bend out of the intercooler untouched as you can see it through the black mesh of the type m front bar which looks quite nice.

Does anyone have any numbers in regards to this stuff yet? The OP menitoned he's of the datalogger type, but hasn't posted anything about actual temps.

I have 2 theories:

One results in a cooler charge.

One results in a hotter charge.

I wouldn't mind looking at this modification further myself, I assume the tar is hard to remove after installation, therefore I'll have to wait.

While I don't have numbers, I've noticed after doing this I swear I can feel a noticeable temperature change from the start of the unshielded crossover pipe, to the throttle body and from the throttle body to the manifold. Obviously this means a considerably lower temperature in the pipes. I do really want to bypass the coolant feed to the throttle body too.

I got a small thermocouple I can use to measure the temperatures I'll do it when I can, I have an exam in 12 days I have to study for now though.

Out of curiosity, what is your theory resulting in a hotter charge?

EDIT: BTW for those who are interested the pipes look pretty good now they're installed, you can see the pics in my garage.

i think you will find that while the pipe is cooler, the amount of temperature difference in the actual air temp is minimal. the reason being that the air is flowing through that pipe at such a speed that the relatively small surface area of metal won't be having much of an effect on the large amount of air. now i'm not saying it wouldn't have any effect on the air temp, but nowhere near as much as is thought by some people. the air is flowing through that pipe in relatively short time, and there is a large volume of it. the principle is the same as how you can touch something hot very fast and not feel the heat, but if you touch it for a longer period of time you will.

this is what i intially thought, it would be great if someone could give some actual before and after air temps, ie, temperatures of the air that is just about to flow into the throttle body with and without the shielding.

when i did this, only on crossover pipe... i covered it with duct tape first, to make it a little easier if i ever want to remove the flashtac, however mine has started to melt the tar on the bend of the pipe... fyi
