Boost limiting valve (Marauder centrifugal SC)
Posted: 2022 Jul 06, 14:41
Anyone ever run a boost limiting valve on a centrifugal supercharger setup? Assuming they work as designed (basically a wastegate with an adjustable spring on the cold side piping), as long as it is BEFORE the MAF on a blow-through setup there shouldn't really be any issue with running one right?
We are trying to get away with running a larger vortech without forging the engine first. If it blows up it blows up, but would prefer to spend the money buying the larger supercharger kit (ADTR Marauder race-kit) instead of spending more time and money later to swap the SC, intercooler, piping, etc. I don't remember how I calculated it, but it seemed like even the largest pulley on the JT trim supercharger would result in far too much boost for the stock bottom end, hence the idea of limiting the boost via a BLV.
Supposedly BLVs can also be used to run a smaller pulley without over-boosting which in turn generates more boost at earlier RPM ranges, increasing the overall powerband without running too much boost at higher RPMs.
