Foil Delete Question

I am going to finally get rid of the awful foil insulation in an effort to clean up the engine bay a little bit. I was wondering if any of you have put heat wrap on the hot side pipe after doing the foil delete? I always like the way that heat wrap looks on motorcycle exhaust pipes (what gave me the idea) and thought it might be a cheap way to make engine look a little cleaner. What is everyones thoughts?

The Foil is there NOT to retain heat (in fact that's just the Opposite of what you want) but rather to suppress the whistle created by the compressor. Personally, I Like that noise!

I don't think heat wrap serves any purpose...

I wouldn't use it to try to gain performance or functionality, just use it to clean up the engine bay. I am going to do the foil delete regardless but thought that using heat wrap (that I have leftover) would create a unique look. Being that it is on the hot side, I can't imagine that it would have any difference in function/temperature. If you think it would then I definitely would not do it.

From the airs compression and the proximity to the "hot" side of the turbo, that's actually where the air-charge is at it's hottest. Maintaining that temp into the IC isn't going to improve anything, but isn't gonna make any noticeable decrease in performance either. I guess it's just the idea that bothers me You have the opportunity to help in the cooling process (by leaving it uncovered) plus adding to the turbo-sound...

As I said, not going to make any kind of difference to the engine whichever you go with so, if it's about "looks" only, go-for-it and see what it does for the under the hood appearance

Foil

Ford put the foil on there to lessen the turbo whine. It has no added cooling benefits anways. It looks good when its all taken off and adds a little whistle, atleast it did for me.

I'm thinking of doing the foil delete on mine as well, but I'd like to keep the whine down a little since this is my DD and use it for the family trips and what not.
But I'm thinking about doing an insulation like lizard skin, Line-X or some other spray to make it look decent while still keeping the sound down. Has anyone else tried this?

when i did the foil delete i still had the stock compressor wheel and it barely added any whistle. i noticed more when i did the wicked wheel because it is louder anyways.

oh and ive never seen anyone re-insulate them. but they do look badass painted or powdercoated!

It barely adds any noise at all. It isn't worth the time or money you would spend getting it wrapped or sprayed. Clean it off, polish it and call it!
