It made much more power than 10-11hp per psi !!

69kw at the wheels = 122.5hp
120kw at wheels = 216hp on 6psi
Closer to 16hp extra per psi


its using a t3t4 razz tech modified turbo, with a full stainless steel gauge 8 manifold, the turbo / manifold / fuel system is designed for 20psi + but currently the stock engine is limiting the amount of boost.
