HKS Boost : Drag Racing : 2530 : HKS EVC EZ

HKS Boost Gauge

This is the actual boost gauge I ran in Big Bird.  R33 GT-R. While competing in IDRC against Pete and the XS Engineering RX-7, I saw the needle pointing at HKS. So probably in the 2.4 kg/cm2 range. About 34-35 psi.  In addition to the boost, I was running direct port nitrous. At 1.8 kg/cm2 with the nitrous the car did 650 wheel horsepower and 132 in the quarter in Palmdale.  Up at HKS boost, she did 137.7 mph.
