Engine Masters

- Season 2

(2017)

Ever wonder what those camshaft specification numbers really mean and how they affect engine performance? Engine Masters is here to help, as David Freiburger explains cam lift, duration, lobe separation angle, and installed centerline. Next, we test a low-rpm cam and a high-rpm cam in the same engine to demonstrate the power differences.

Usually on this show, we are all about making more horsepower, but on this episode of Engine Masters, we are trying to kill horsepower. We bolt four different types of cooling fans onto our 350 small-block Chevy, all with different designs and material. Which one takes the most horsepower, and which one takes the least? Watch and find out.

Engine Masters presented by AMSOIL reinforces the fact that Steve Dulcich is not just the guy in the back of the dyno room-he's a legit engine master. And you won't question that after you see his homegrown porting job on a set of Edelbrock aluminum cylinder heads for a small-block Mopar pick up a whopping 92 hp. To be fair, that gain also includes porting work on the Victor Jr. intake manifold by Bryce Mulvey. All this work tops off the same 410ci small-block Mopar from BluePrint Engines that was seen on Engine Masters Episodes 11 and 18.

We test the power of straight dual exhaust with no crossover pipe versus using an H-pipe versus an X-pipe. Will the old bench-racing stories come true, or is it all hocus-pocus? We find out using a basic 5.3L GM LS3 engine then precisely spell out the effect these exhaust-system modifications have on horsepower and torque.

We take the Roadkill Rotsun and find out how much power that bone stock turbo charged 1987 5.0L Mustang engine really makes. With a science experiment of a rig, get ready to be shocked. The numbers don't lie.

Get ready to explore an ancient scenario but still one of the most-asked tech questions we are asked: What budget bolt-ons can be used on a stock small-block Chevy 5.7 to get more horsepower? Watch as we take the cheapest Chevy 350 crate engine you can buy and make mods that gain nearly 130 horsepower. It's a dyno-proven, easy-to-install power combo that will give you the best bang for your buck.

There's nothing we love more for big torque and visual impact that a good ol' antiquated roots supercharger. This time on Engine Masters, presented by AMSOIL, hosts David Freiburger, Steve Dulcich, and Steve Brulé show you how to install and tune a Weiand 6-71 blower and dual 750-cfm double pumpers on a budget 350ci Chevy short-block.

Engine Masters find out if you can stuff 25 psi of boost into a cast-piston, stock-crank short-block and have it live. Watch as we strap a ProCharger centrifugal supercharger to a bone-stock Chevy 350 bottom end and keep stepping up the boost to find the breaking point. But there's a hitch: At the start, we agreed we'd let the engine live if it could make 750 hp and survive. So did we leave parts on the floor, or did we make stupid power with a foolish combo? We'll tell you this much now-we did the best we could to show you blow-through boost tuning by keeping the ...

If you've ever wanted to know if a car's high-performance air filter makes a difference, or if your small filter is killing horsepower, you've come to the right video. Engine Masters test a whopping 19 different combinations of filter sizes and styles including paper elements, K&N filters, stock housings, dual-snorkle housings, velocity stacks, filtered lids, and way more-all the way up to some shocking results with tablewear. Our test engine is a 750-horsepower, 496ci big-block Chevy, but the data we gathered is relevant for any engine down to about 300 horsepower.

We test the long-standing Internet theory that too big of an intake port kills bottom-end torque. Watch us take the mildest of 408 Ford small-blocks and try to make the torque curve dance by bolting on three different heads from AFR. Will the myth be busted, or will we stumble upon a surprisingly awesome combo for a small-block Ford? The answer to at least one of those questions is YES!.

One of the most common valvetrain upgrades for pushrod-style engines is roller rocker arms, which are often said to increase horsepower through reducing friction. But is it true? You'll soon find out as we use a 7,000-rpm, small-block Chevy to test stock-type stamped-steel rockers, roller-tip rockers, full rollers, and full rollers with a ratio of 1.6:1 rather than the stock 1.5:1. We'll reveal the facts and myths around the horsepower claims and discuss other things you need to consider before purchasing any rocker arms for performance engines of any kind.
