Engine Masters

Engine Masters, presented by AMSOIL, is an all-new show for the Motor Trend channel! Each episode takes you into the engine-dyno room where power claims are questioned and head-to-head shootouts ensue. Engine Masters finds the truth about speed parts and

Should you run a carburetor, or should you try the new and easy self-learning EFI setups? We’ll dish up answers in this episode of Engine Masters, presented by AMSOIL. Host David Freiburger, Steve Dulcich, and Steve Brule strap a 5.3L LM7 engine to the engine dyno and look at the price, installation, and power of a Holley 750-cfm double-pumper versus Holley’s Terminator throttle-body EFI.

It's our first head-to-head shootout with two engines: a Blueprint Engines crate Chevy 383 small-block versus a hand-built Mopar 383 by Engine Masters host Steve Dulcich. To make this a fair test, we equalized as many variables as possible: both en

If you've ever installed a set of high-performance exhaust headers, then you've probably bashed those exhaust tubes with a hammer to get them to clear everything in the chassis of the car. It's a super common problem, but people often

This time on Engine Masters, presented by Amsoil, you'll learn a good combo for 470-plus horsepower from a stock-bottom-end 5.7L Dodge Hemi, and then see us add a Paxton supercharger in the hunt for 707 horsepower just like one of the new Dodge Hellcats.

Topping your engine with a set of aftermarket cylinder heads is a near-certain method for making more horsepower and torque-but is the extra power really worth the money? In this episode of Engine Masters, presented by Amsoil, we answer that questi

Dual quads! Three deuces! Eight barrels! Six jugs! The lore of multiple carburetors runs deep in the hot rodding world, and in the muscle car era it was common for the OE manufacturers to up their cars' performance and image with either two four-ba

Boost is good. Forced induction makes huge power, and you want it cheap and easy. This time on Engine Masters presented by AMSOIL, we look at the two most affordable implements of boost from SummitRacing.com: a Paxton Novi 1200 blow-through-carburetor cen

You're sitting around with your typical street/strip V-8 and wondering, should I get 2.5-inch-diameter exhaust pipes and mufflers, or should I go 3-inch? In this episode of Engine Masters, presented by AMSOIL, we will help you decide, giving answers about

In this episode of Engine Masters presented by AMSOIL, you'll learn a simple combination for a 600hp big-block Chevy. Many people building engines like this are torn between the streetability of a camshaft that uses hydraulic roller lifters and the

The 408 is one of the most popular small-block V-8 stroker combinations for Chevy, Ford, and Mopar. This time on Engine Masters presented by AMSOIL and supported by Earl's Vapor Guard and Mr. Gasket, we take the first step to find out which engine

In episode 4 we famously destroyed a set of Hooker headers with a hammer to see if dents in tubes really make a difference in performance. Folks said our test was flawed because if dents in the tubes didn't affect performance, then the headers must have been too large to begin with.

The 13th episode of Engine Masters, presented by AMSOIL, is an unlucky one for a poor little 305ci Chevy small-block. It was the victim of our test of how much nitrous oxide power boost can be tolerated by a completely stock short-block with the original cast crank, rods, and pistons.

In this episode of Engine Masters presented by AMSOIL, we show you why the age-old concept of pulling a used engine from a running car and slapping some speed parts on it might not always be the best idea. Our guest engine is the Mopar 360 small-block V8 from Episodes 3 and 4 of Roadkill Garage. We set up the 360 with all-stock parts, ran it on the dyno for a baseline, and added speed parts.

Cast-iron manifolds versus mid-length headers versus long-tube headers: Which one is best for you? In this episode of Engine Masters presented by AMSOIL, we again look to our loyal fan base to feed us ideas of power tests they want to see.

On this episode of Engine Masters presented by AMSOIL and supported by Mr. Gasket and Earl’s Vapor Guard, we will spell out the differences between a hydraulic roller cam setup and a low bucks on the old-school flat-tappet cam.

In this episode of Engine Masters presented by AMSOIL and sponsored by Mr. Gasket and Earl’s Vapor Guard, we explore whether the price of a muffler makes a difference when it comes to performance.

In this test of “there’s no replacement for displacement,” the hosts of Engine Masters presented by AMSOIL and sponsored by Mr. Gasket and Earl’s Vapor Guard run a dyno comparo you’ve probably never seen before: two engines with all the same specs except for the crankshaft stroke.
