did anybody used this pair ever?
i have some problems with it.
from 4krpm to 8000rpm i have 10psi boost,but when i am at 8500 it gets 20-22psi boost.
the setup:
darton b16 81mm
sc6176
35mm wastegate
custom eq lenght manifold 1,8inch tubes
3"inch downpipe.

Wait a minute, are you getting more or less boost then you want?... what psi are you trying to run? If all you are trying to run is 10psi then the problem is boost creep (either poor wastegate placement or too small of a wastegate or both) which shows up when the motor/turbo creates more exhaust than the wastegate can get rid of.
On the other hand, if you want more than 10psi and dont get it til really late in the rpm's, then you most likely have something wrong with the setup unrelated to the turbo/motor combo (such as a leak in the intercooler/piping) good luck!

i would go 10psi boost for beginning
but it gets creep when i rich 8000rpm,but if i set up the wastegate for 15psi boost it makes it!from 5000to 9000
i think this turbo is little big but it is not a problem.
