The Blow-off valve is essential to all turbocharged vehicles. The
purpose of the BLITZ Blow-off Valve DD is to relieve compressor surge
without reducing compressor speed. It controls boost pressure that is
built up by the turbo and vents it into the atmosphere when the car is
not under load (in between shifts). This prevents pressure from backing
up into the compressor housing, causing the turbo impeller blade to
rapidly stop or even worse, to spin backwards (compressor surge or
backspin). Doing so can be potentially destructive to the turbine wheel
and shaft. Repeated stress over time can cause eminent damage to the
turbo charger and eventually lead to turbo failure. A blowoff valve is
actuated by pressure changes only, ensuring quick valve responses and
complete closures at idle. The BLITZ blow-off valve not only improves
performance and response, but also increases the life of the
turbocharger. |
