20 bucks Turbo heat shield
 
9 Attachment(s)
Well here it is. I went to home depot and bought a nice big 12x24 piece of Aluminum - $9.xx.
I was thinking fo wrapping it around and over the turbo but i settled on this design due to its simplicity and i wanted to leave some air for the turbo to get some ventilation at least from the radiator fans

red = area completely removed from sheet
blue = fold line
blue circle = bolt

Also 1 question, When bending the metal pipe that goes underneath the headers/manifold for the heater hoses, i crushed it a little bit. Will that be a problem? Its not penetrated however its crushed a bit.

after further talk in this thread, i decided to add a top to my heat shield which doubled the price of it however its still less than half the price to the next alternative from the store/internet.

if i had done this out of the car the folds would have been on the inside and looked much better but i got lazy

few pics of my top cover

The hood paint is gonna get jacked.

triple88a 11-11-2009 10:31 PM

I see, alright then i'll add a top cover to it.

I like it more than the one BEGI sent me. Sorry Corky. :(

Looks like it's only bolted to the chassis, not the engine? So that when the engine rocks the shield doesn't move--I take it you have plenty of clearance so no hoses/wires will rub up against it and chafe.

triple88a 11-12-2009 12:42 AM

I have it tied to the last bolt at the valve cover until i get a longer piece of metal so i can tie it to another place.

There is about half an inch of room between the downpipe and the shield and there is about an inch of room between the turbo and the shield and about half an inch of room between the coolant fitting and the shield.

In the front its held by the bolt that holds the ps fluid bottle and the 2 other bolts that hold the stock air box, in the middle is tied to the bolts that hold the bracket that held my windows washer bottle and at the end its held to the block via that bracket on that last pic however i'll move it to the body tomorrow since i'll get some more of the metal shin i need.

What i like about this is that it doesnt need any special screws or anything new drilled, it uses all the old holes and stuff.

I'm also thinking of buying a rubber line and cutting it on one side and putting it on top so it doesnt have that sharp edge.

Bolt it to the chassis or the engine. Not both. Recommend chassis.

triple88a 11-12-2009 01:18 AM

Will bolt it to the chassis tomorrow :)

I've seen something like this before......Oh right, its been on my car for 4 months.

Also, I have 0 issues with my paint. However, all the glued points on the under frame of the hood have come undone from the heat. Luckily its welded on the perimeter.

Good ideas.

triple88a 11-12-2009 01:28 AM

i see, well thank you for the feedback sir, i'll add a top and some more heat shielding to mine just in case

My first design was similar to the FM box however i changed my mind since i wanted to block the direct air going to the heater hoses.

Any info about the metal pipe i pinched?

It will obstruct heater flow a tad. Unless it is severely crimped you should be fine. If you are careful you can take channel locks and squeeze the sides of the crimp to open it back up again. This might fatigue the metal and cause it to crack.

triple88a 11-12-2009 07:12 PM

but no problems to the engine?

triple88a 11-12-2009 10:10 PM

haha Perfect turbo cover

So does it do its job?

triple88a 11-12-2009 11:05 PM

which one? my heatshield i made above in the 1st post or the flux capacitor? In the mourning, on my way to work, the hood was very frozen. When i got there i checked it out. Around the turbo it was dry, over the engine block it was melted, on the other side of the wall i made by the air filter. It was still ice like it was before i even started the car. You could see where the heatshield is at. There was a fine line between the dry and the frozen part on the hood.

1stproject 11-12-2009 11:18 PM

That answer's my question. I guess it does work.

r808 11-13-2009 05:56 AM

The flux Capacitor was never designed to be bolted to both the engine and the Chassis at the same time. 88 MPH can easily become 103 MPH with a little fudge. LOL.
