Message	use a turbine housing with an A/R of .86. This higher A/R number allows better flow of gases at high engine RPM. The reason I noted that was because there was a dynochart from a car which made just shy of 600RWHP also and claimed it was with HKS2530's, but it was noted that they had an A/R of .86, which would make it a disco potato turbo. This one change to the design of the turbo shifts the torque into higher RPM which means it will make more horsepower. Even with the genuine HKS2530 turbos(with .64 A/R), we still made just shy of 600RWHP. SAE corrected was 587RWHP on Chris's car.
