Default 3d printed adaptors

I already prinred 2.5 and 3" connectors for testing purpose (china post is so long). I m a bit embarassed with the cross of turbo intake/outake hose and dont want to struggle anymore with problens to close the hood. I wanted to shape an adaptor wich is curved on his top with ny 3d printer and wanted to know you thinkings... this part will be in intake side of the turbo hoses. Do you think they will not support temperature there (it s abs plastic so start deform at not so high temperatures). Do you have any other concern about use it? Good idea?

you dont want the 3d printed piece breaking apart, then turbo sucking in the plastic and bending the compressor wheel.

ask me how i know.....



This was a rubber piece that broke off my air filter.



$375 later, i had a billet compressor wheel.

i have the exact same air filter!! How does that happens!? Did you use it a long time before happens? Was it really close to the turbo or not at all?

This is a piece of **** china knockoff of k&n, rubber is super soft, not firm and strong like real k&n, so it got torn while I was at the drag strip. I guess from the vibrations and stresses. Real k&n will not tear like this.

lesson learned and buying k&n filters on eBay out of china

It was also partially my fault, the clamp was crooked and the bottom of the filter snapped off the pipe and torn.
it was mounted on a 12" long 90 degree tube away from the turbo

I 3d printed my turbo inlet with nylon. Seems to be holding up fine, it should be easily good to 300F, possibly higher depending on stress. I should have annealed mine to make it last longer. I'll probably eventually replace it with flame retardant PC.

my "real" K&N ripped in a very similar way. I feel like mounting it directly to the turbo just isnt a great idea. it gets shaken to hell, and its tight jammed between my headlight motor and heat shield. Gonna add some inlet piping to extend it and give it another coupling to reduce some of the vibration.

luckily it didnt get sucked it.

yes your config is really different from mine (i have two hose + maf + adapter before the filter) it will not happen with me...
no luck sorry.

weird, i guess chinese ones are really that crappy. i would have guessed that the extra flex would help it from breaking down. the chinese ones clearly arent designed to have that much suction on the other side of it. good luck with your new one. there you can have that luck
