I have a s300/ ht3b setup and i have a boost gauge in the intake and in the pipe between the two turbos. I am needing to know what is a good number to have on boost on the one in the pipe beween the two turbos. i am only getting 15 psi there and i am getting 50 at the intake just wanted to make sure they are working porperly

top turbo boost

i would play with the waste gate on the top turbo and try for around 20-25 psi

20-25psi top charger and around 30-35psi for the bottom....but you will also want to check the drive pressures.....run a gage in the exhaust manifold to read that and waste gate it as close as you can to 1:1....i would guess around 65 psi should get you close 1:1

How do i figure what the top charger is making? do i take intake manifold boost-Bottom turbo boost and that will give me top turbo boost
