Another myth, The airflow through the TMIC at speed is excellent. I covered many thousands of miles on track with regular 150MPH sections with stock TMIC setups and monitored the charge temps, you dont get any issues with airflow through the core.

I'm very much a fan of TMIC setups, you do get better throttle response with them, just like any setup, if it's tuned correctly you will get good performance out of them, even in a sprint environment which is probably the worst scenario due to heat soak whilst queuing.
