Default Need bov help

Like the title says I need help sizing bov's for my 6.0 setup. the setup is twin 57mm turbos on a 6.0 iron block LQ4. I want to run 8-10 pounds of boost if possible.

Thanks in advance.


Steven.

I would say JGS 40mm units would work perfect for you. Also they are very affordable. Contact Modular Turbo for a good deal on them! The spring that is in the wastegate is a 7lb spring and they also come with a 10 lb spring. I love mine no creep at all.

I think you are confusing wastegates with blow off valves.

any and all information is appreciated. I'm pretty new to turbos and sizing is what really gets me.

Sorry I miss read your post. You only need 1 BOV and I like the JGS 56mm unit. It is a awsome piece and is around $250

2 38mms should be fine if you want to run atleast X amount of boost all the time you need a spring a littler lower than X. The spring basically provides the minimum amount of boost you can run ie you cant have a 10psi spring and want to run 8.

Im not sure on a twin setup, I would imagine the pressures would be combined so 2 WGs at 5 psi would probably equal 10psi(I would say closer to 9ish). But im really not 100% on that one...

Yeah it works the opposite of what you said. If you want to run 10 psi then you want twin 10 psi springs. Each gate works seperately and they will have a combined pressure as a reference. Where you reference the gate will change it alittle bit, but get the spring that is the base pressure you want to run.

Oh ok. much more understood now. I'll be checking the springs when they come in to see which ones they have and if need be i'll get diffrent springs.
