blow off question

[Gost]

on a twin turbo setup do you really need two blow offs, one for each turbo, or would you just use one for them both? im not doin this, i was just curious.

im pretty sure you need 2 unless you run the turbo outlets from 2 pipes to 1 then it seems that u could run just one after the merge

1 on the cold pipe. 2 if you have 2 cold pipes like the 300zx.
