I'm aware of that issue, I saw clt temps go up by around 5c or so after the ducting at the back of the head.ivan141 wrote:That ducting solution for your air intake will probably lower your cooling efficiency. It relieves the pressure differential across your radiator somewhat, which in turn lowers the airflow through it.
One duct wont make a drastic difference, but I've seen friends who put a hole in the panel next to the radiator loose precious seat time at track days due to overheating problems they didnt have before the mod.
An airbox would be the best solution for a good supply of cold air.
I'm thinking of making a naca duct on the driver side fender to bring in air to the turbo from there instead.
