Just had a workshop call me, they took a VF GTS to Eastern Creek circuit racing last week car makes over 500rwkw, running 15psi of boost spinning the living hell out of the blower.
They retained the factory heat exchanger combined with the chiller and our 6.5L reservoir and our LSA lid spacer.
Intake temps did not go any higher than 28-35c
This is the first collected data I have been provided from a workshop using the car for circuit racing.
