do you think 2 hks ssq blow off valves are efficient for a t70 turbo. there adjust all the way to hard and i sware there leaking boost cause i can hear them whistle while under boost.

i will just get 1 tial 50mm in the future,but till then wtf is up?"

 

Not sure, cant say I know whats wrong. I run 2 50mm tial vlaves on my setup. The springs are 7psi and they are open when the car idles but on the gas they close and stay closed till you back off.

 

i hate that compressor surge noise and those bovs that make a similar noise. So having 1 50mm valve on each side of the intercooler releases all the pressure. Get a double whoosh and no chechchch crap.
