Nah, just under boost. That is the only time you're going to have problems with FI for towing. Hell at anytime really LOL.

If you are towing a heavy load up a VERY long incline.. IE The Grapevine then that's when heat soak could become a problem for a turbo or a blower truck. Trans coolers and IC's need to be big/efficient enough to handle the task.

 

gotchya, so far I have been extremely impressed with how cool the intercooler fluid stays in the system.

 

Its funny how everyone is talking about which is better. Turbochargers and Superchargers are very different. I like them both. It all depends on how your motor is setup. The reason why top fuel drag car use superchargers is because the blower is use to assist the motor and make additional power. Turbochargers are designed to make power. Thats why a lot of Japanese cars have them because the motor can't make enough power. The motors are simply to weak. I have had both and I love em. The Radix is an awesome kit and make unbelievable power on a stock motor. The Livernois turbo kit is also a good kit and makes good power on stock motors but has the potential to make way more power depending on the internal parts of the turbo (A/R, ball bearing, trim, etc). Turbos do break more, are harder to maintain and can add up to twice as much as a supercharger kit.
