I have a tial 50mm bov with a 3psi spring in it from the previous owner that had it on a supercharger set up.
I will be running it on my turbo setup going for 700Hp on c16 and mid high 400s on pump with a borgwarner s366 turbo. What weight spring do i need to run on this bov for thos kind of numbers

I run yellow.

 

I have pink if u want

 

Dark pink

 

I run the "plain" one

 

I run a plain color spring on the older tial 50mm. I just bought a white spring to try out, see what happens.

 

I'm running the dark pink spring. I think it's too stiff. Bov is fully closed at idle

 

You just bumped a 5 year old thread..
