what size/material do you make turbo downpipes out of?
|
home depot pvc pipes
|
that could end very messily. Unless you can bend a 2.5 to 3" dia steel pipe, and weld on flanges... just buy a cat replacement pipe
|
inconel!!!
no but seriously SS or painted mild it really doesnt matter all that much as far as function goes. |
Ideally 321SS, however good luck finding it in a decent size and be prepared to pay a lot https://www.nopistons.com/forums/pub...IR#>/smile.gif

is ss304 a goog alternative to ss321?
|
ss304 or aluminized steel is good and is easy to work with and there is almost endless sizes and bends out there avalible to make almost anything.
|
if i thought ss321 was to expensive why could i not use ss 304?
It seems to be about 1/3 the price from http://www.burnsstainless.com/304tubing/St...traight304.html mechanically speaking they are really similar the melting point of ss321 is 1400-1425C while ss 304 is 1400-1420 the only main difference i can find is the coefficient of thermal expansion of ss321 is 16.6 vs ss304's 17.2 at 100c. these numbers get closer as temp increases. i dunno... i doubt the difference in the amoutn the materials expand would be noticable. everyone says to use ss321 but it doesnt quite all add up to me. im sure im missing something..... does anyone know? |
o and what size piping do you normally use coming out of the turbo. where can i find the outlet diameter of the turbine?
|
depends on what housing you have and what exhaust you want to run. most outlets are 3" but some are 2.5"
oh and dont buy from burns stainless, they are the most expensive place you could possibly find, just look around and you will be able to find some cheaper prices. |
