The Throttle-Body Throwdown!
14 April 2023The crew compares 90 mm and 105 mm forward-facing throttle bodies against one another, and then to 2000 cfm worth of top-mounted, dual quad-style throttle bodies, all atop a fuel-injected, 700-hp LS7.
Hot intake air temps are bad and cold is good; the guys explore the benefits of an air-to-air intercooler in terms of power and detonation resistance.

Exploring the effects of different sized water tanks and their ability to keep the intake charge colder longer; air-to-water intercoolers make power by absorbing the heat of the intake air into the cool of the IC's water.
Testing shows that carbs make more peak power than EFI, and the explanation is based on the fuel's ability to cool the incoming air on its way to the head, while multipoint injection might not do that.
