An air ductless addition to the intercooler kit for Nissan GT-R R35 spec.
The performance of intercooler of stock is fine for normal stage, but for the tuned car of 1.2k boost-up (GT570, GT600 kit) can reach high temperature rapidly because of near flow capacity limitation of turbocharger which is that the stock core size is small capacity. To improve the cooling performance, more core capacity is required but a little bigger intercooler than the stock could not provide enough cooling performance. Therefore we have employed size of 400x260x65 and thinner core type for much better cooling performance.
HKS Intercooler is lighter than the stock Intercooler that gives over-hang weight trimming effect.
(Stock: 21lbs HKS: 17lbs)
For losing pressure by the thinner core design we have revised inner fin to keep down the increasing pressure loss.
◆Influence to the water temperature
For the large capacity core, the air to radiator cause problem of rising temperature. We have solved this problem by making the core thinner which increases the speed of air passing through the radiator. We have tested at racing track with racer driver and confirmed the water temperature.
