im currently running a 38mm bov and just bought my self a brand new turbo 60 trim, dont want to risk smoking the turbo because of comp surge.

when do you need to upgrade to a 50mm?
on what conditions?
turbo size?
boost?


did have have comp surge on my previous setup..but now the vacuums are straight to the manifold, car is still not driven.

 

dont worry, if your pushing 20+ lbs , or i would say 300+whp then yea

But the Tials 38mm still do a great job regardless. If your not running a tial or another reputable brand, then i would look into it

 

no bro, im running on a really old turboXS

 

know what your in/hg at idle and get the proper spring for the BOV and you will be fine.

 

+1

or u can use a electric boost solenoid to control the WG opening. If your unsure how this works, consult your tuner.

 

he is talking about bov and not waste gate


cant beat a properly setup tial 50mm imo

 

whoops, just saw 38mm and thot WG.. my bad

 

^^ its alright.

i dont think turboXS provides spring rates for their bov's.
