Supercharger Advice

[modo]

no, that's absolutely not true at all. Superchargers also boost under load, they do not only boost under WOT.

centrifugals wont start building boost until 0in of vacuum, the only time you see that is WOT.

with an Eaton ive seen small boost numbers at high loads without WOT, I would imagine all positive displacement blowers would be similar, but all centrifugals with the plastic Bosch bypass need WOT.

take the vacuum line of the bypass and it will build boost but that is pointless and can hurt the blower from compressor surge

well yeah, that would be the same as no manifold vacuum!
