Twin Bov

[drgnball34]

engine in process of getting built with t04z and power target of 650rwhp. I already got hks ssqv...if i was to run the turbo at 2bar, would i need an extra bov? Or should i go for something like the tial bov?

cheers

GTR BOV's.

less than $150, hold over 600rwkw.

Choice is simple

Many don't run one at all, so you don't need anything.

If its job is to dump air, and a bigger one... umm, dumps more air, then i guess you have to decide if... you want your impeller slowing a bit, or less then a bit by use of a larger one (or two)

Crank 2bar into it, and if it flutters when you back off, I guess go bigger.

Id suggest its a setup / driver preference thing

Do you deem that mandatory / beneficial? ~$500 is a lot of BOV'ing

f**k you're patient.

I would also love to know how a certain blowoff valve can "hold" a certain amount of POWER. I'd love to hear that explanation.

i wouldnt say its mandatory but i plan on pushing a fair bit of boost into my motor so ii think its a good idea to have a big enuff bov

i run 26psi threw my GT3076R on my SR20 and that turbo didnt last very long

Didn't last long cus lack of BOV's? Iv never seen a turbs get damaged due to lack of BOV

Any new garret turbo should last a looong time. Turbos outlive engines in the trucking business... and they're always on boost

mine lasted about 6 months ive got a new one coming over frm the states now

i do have a bov but ive got it adjusted as tight as can be

dunno if it was the cause of it or not but i dont realli care, ive always used a BOV on all my cars because i tend to run over 20psi with all my cars i just adjust them as tight as they can go and if the turbo dies it dies i'll get it rebuilt or ill replace it

If you adjust them as tight as they can go, then they probably aren't opening at all, so whats the point of having one?
