Stainless heat shield gauge thickness for turbo?
I was wondering if anyone knew the gauge thickness of the stainless heat shields for the turbo chargers. I'm getting a custom one made and wondered what the gauge thickness was of the aftermarket brands out there.

Depends on if you plan to add stiffening ribs to it or not. The OEM shield is stamped with stiffening features and is quite thin (don't ask me how thin...). The aftermarket ones I've inspected are generally folded and sometimes welded, most are x2-x4 more thick than the OEM shield.
I would stick with the OEM shield if you can and trim it to fit. It gives better coverage than any aftermarket shield could ever hope to. |

Thanks car_freak85. I don't have an OEM one and mine is not in your typical engine bay so it would probably hit something Was hoping someone could just measure their aftermarket one for me.

Or take off turbo, disassemble hot side, send to jet hot coatings or similar for a colored heat coating. Itll add bling and additional protection to your engine bay and added HP. https://www.jet-hot.com/thermal-barrier
Later you could fab up a simple 1-3mm SS plate with a brake alone |

It really depends so much on construction method. If you have a means of bead rolling and forming, I'd go with two thin layers and roll the inner layer so that it leaves and air-gap. Then you tack weld it in place.

Ended up getting an aluminum one done. I'd like to get it powder coated . Do you think the powder coating will crack after awhile ?

I make these heat shields out of 304 hardware and Aluminum sheet.
The aluminum sheet is .050 thickness and works pretty well. They can move around and clamp to similarly size pipes. For smaller pipes i just get a smaller clamp and bend a tighter radius. Hope this gives you ideas! I can always make one for you too, I sell them for $25 + shipping |
