Turbine Housing Cracks
MY 16G has about 4 or 5 superficial cracks in it (by superficial i mean not all the way through yet). I think its already been ported in the exhaust housing to remove cracks once, should i try it again or let it slide and baby it?
|
who babies a turbo?!
|
let it slide and beat the crap out of it... 16Gs aren't that expensive to replace ;)
|
oh yeah i'll post pics tomorrow
|
Mine has them too. Who cares?
|
If they don't go all the way through they don't matter. In a worst case scenario these 7cm turbine housings are not expensive to replace. I've ran many cracked MHI turbine housings. Worst cracks I saw were on a stock Talon 14B and even they didn't go all the way through or hurt performance.

well i was just checking before i put anything on, thx for the info

you can stop one from spinning at idle with your finger :gay:
the problem here is, do the cracks cause the exhaust to leak past the turbine wheel....or will the eventually do so. if eventually, how many heat cycles will cause it. 1400° cruise can do it. as easily as 1600° in boost. |
cracks mean more surface area for cooling :gay:
|
There's no "babying" a turbo. Just beat the shit out of it and when it grenades, replace it.
|
And hope little pieces of turbo don't get sucked into your intake tract.
|
nothing a little mesh filter inside the charge pipe cant stop...
we should make one, huh? just a little metal mesh filterwelded inside the charge pipe, not to dense, just to stop shit like broken off metal etc. what do ya think |
I dunno...
I know this is a little extreme, but one of the fire engines at my work had something sucked into the intake of the turbo, broke a lot of shit in the compressor, and the outlet of the compressor looked like someone had taken a chisel and scored it pretty deep... then the "mechanics" tried to tell us that the engine was fine and didn't ingest any metal. I realize a diesel is a tad bit different than a petrol engine, but I wouldn't trust any of it. |
