Engine Masters

Engine Masters presented by AMSOIL is an all-new show on the Motor Trend Channel featuring parts testing and engine-to-engine shootouts. Developed from the popular Engine Masters Challenge – a dyno shootout event also presented by AMSOIL – Engine Masters on the Motor Trend YouTube Channel is hosted by David Freiburger of Roadkill, Steve Dulcich of Engine Masters magazine, and Steve Brule of Westech Performance Group.

1. E1. Air-to-Air Intercooler, Now With CO2!!

   Mar 24, 2023 · 23m

   Hot intake air temps are bad, and cold IATs are good, right? But how bad is bad, and how good is good, especially in a boosted application? To find out, the guys explore the benefits of an air-to-air intercooler in terms of power and detonation resistance. They also test out external CO2 foggers that keep the intercooler extra cool.

2. E2. High vs. Low Injectors

   Mar 31, 2023 · 23m

   Our testing has repeatedly shown that carbs make more peak power than EFI, and our explanation is based on the fuel's ability to cool the incoming air on its way to the head. Multipoint injection just can't do that. Or can it? We move fuel injectors up the intake manifold runners to see if the extra distance of suspended fuel makes extra power.

3. E3. Tank Testing for Air-to-Water Intercoolers

   Apr 7, 2023 · 23m

   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.

4. E4. The Throttle-Body Throwdown!

   Apr 14, 2023 · 23m

   The 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.

5. E5. Bellmouth Power

   Apr 21, 2023 · 23m

   Call it a velocity stack, a radiused entry, or even a salad bowl, the bellmouth is designed to direct and smooth the airflow into the throttle body, creating a more efficient airflow. But does it make power? We'll answer that very question for both N/A and supercharged versions of our 363ci small-block Ford.

6. E6. Sequential vs. Batch Fire EFI

   Apr 28, 2023 · 23m

   The reputations of sequential and batch-fire injection styles each carry when it comes to overall power; the guys explore that question, tunability, what it takes to make the switch, and all of the pros and cons.
