Engine Masters

On this episode of Engine Masters, presented by AMSOIL, we dive into another hot topic across the web: the relationship between cylinder head flow, the liberal application of boost, and the production of horsepower. 

Suppose you cruise around town with 87 octane in the tank. Could you pull up to the track, pump in 110, crank up the timing, and actually make more power?  That's been a lot of guys' working theory for years, and we're here today to find out. See what happens as we pump up the gas on this episode of Engine Masters, presented by AMSOIL.

On this episode of Engine Masters, presented by AMSOIL, we outfit our ProCharger-fed Ford 363 with a Demon 650 blow-through carb and with Holley's new Super Sniper Stealth throttle-body-style EFI to determine which will reign supreme in terms of tunability, cylinder-to-cylinder distribution, and of course, the almighty horsepower!!

Do mandrel-bent exhaust pipes really make more power over the crimped and crunched pipes the local shop bends up? We’re about to find out as we run mandrel- versus crunch-bent systems on a 530-hp LS3, on this episode of Engine Masters presented by AMSOIL.

This time on Engine Masters, presented by AMSOIL, we aim to find out as we test 10 different filters back to back to back. From the cheapest off the shelf to the trickest in the catalog, we're on the hunt for the best flowing and best filtering units you can get your hands on. 

Since the dawn of supercharging, compressed air has been stuffed through carburetors, and it's as true now as it was back then. The question we're asking today is: What type of carb hat is best for that blow-through application? Come see just how much on this episode of Engine Masters, presented by AMSOIL.

Roots Blowers, Tunnel Ram, Intercoolers, and Big Blocks! What more could you ask for?! On this episode of Engine Masters, presented by AMSOIL, we're on the hunt for two things.

Do matched intake ports really make power? Is it worth the expense? Come find out, on this episode of Engine Masters, presented by AMSOIL.

On this episode of Engine Masters, presented by AMSOIL, we'll be testing the actual headers, intake, fuel system, and everything that will actually be used in David Freiburger's Model A drag car, making sure it all works on the dyno rather than on the dragstrip.

On this episode of Engine Masters, presented by AMSOIL, Holley carbs have been known for years as the standard by which all racing carbs are measured, but today's question is this: CFMs being equal, is there any difference in power between the smaller-bore, narrower-set "street" style 4150 carb and the bigger-bore, wider-base 4500 series Dominator carb?

Does compression make power? The easy answer is yes, but the answers we're looking for today have more to do with how it makes power and how sensitive it becomes to temperature on pump gas. Be ready to be impressed by two very good engine combos and a strong case for compression on this episode of Engine Masters, presented by AMSOIL.

It's the battle between the iconic 440 Six Pack and the legendary 426 Hemi, and we're settling age-old bets on this one. Do they live up to lore of 440 grunt and 426 top end?  Can the Six Pack cool outgun the famed Hemi heads?? We'll find out on this episode of Engine Masters, as we bolt both to dyno.

Need we say more?! We're taking trips to the moon as we test different combos on a 331ci small chevy. Starting with an excellent little combo good for 7K rpm, we step it up to show you how improved airflow on a small motor equals pure rpm. Best of all, we do it all with simple parts and a small budget. Come take a ride on this episode of Engine Masters.

Sounds boring, we know. But if you're like us, you've always chosen an oil pump based on some knee-jerk instinct. It's time to finally learn the difference between standard, high-volume, and high-pressure oil pumps in terms of pressure, flow, and horsepower. Come see what there is to know on this episode of Engine Masters.

Street-car turbo people, this one's for you. We all know that adding any sort of restrictor-like a muffler-is going to hurt power on a turbo motor. We also know that sometimes it just makes sanity-sense to cut down excess noise.

We love our big-block Mopars here at Engine Masters, and we've finally put together a horsepower-per-dollar comparison of street-centric Wedge cylinder heads. Want to spend bottom dollar on some 906s? We've got you covered. Want to step all the way up to CNC-ported, tall valve set of TFS's? Tested. Come see the cost of these gains-and all the ones in between-on this episode of Engine Masters.

You've seen them, you've drooled over them, and you may have even run them. We dive into the wavy waters of individual runner systems, how you can tune them, and whether all that cool makes any more power than the stalwart carburetor.

That’s right, barrel. This is not a comparison of your readily available pump gases. This is a study of fueling demands, horsepower, and the pros and cons of running each: 116 octane gasoline, E85, methanol, and oxygenated gas. They all have different oxygen contents, air/fuel ratio demands, and ultimately, different abilities to cool the cylinder and create power.

Turbo power, pump gas, and no intercooler.... Can you really have it all? That's the question Engine Masters is asking as we explore the cooling benefits of water-methanol injection. We'll be looking at any added tolerance to detonation, intake air temps, how much to inject at what rpm, and the optimal ratio of water to methanol. 

We've done air filter shootouts before, but none like this. On this episode of Engine Masters, it's all about finding the least restrictive way to route a cold air system. 

The juice, the bottle, the squeeze! It goes by many names and every one of them means horsepower! On this episode of Engine Masters, we dive into the fundamentals of the cheapest, easiest, and most effective way to give your motor some grunt: nitrous oxide. 

When it comes to selecting a camshaft, there are plenty of decisions to be made. On this episode, we're exploring the differences between single and split duration camshafts. Can the extended exhaust duration of the split pattern crutch poor exhaust flow? Does the single pattern really suffer at rpm in the name of low-speed torque? Why would you ever not want to run a split pattern? 

It's finally time for some 5.9 Magnum action! This is hands down the easiest Mopar V-8 to score out of the junkyard, and we're shooting out intake upgrades for a street car swap. Come see what kind of basic bolt-on power is available for this elevated-LA engine as we pit the factory kegger manifold against a worked-up aftermarket piece.

Some claim it makes more power, others say it helps an engine rev more quickly, but can the simple flopping of a piston's orientation in the cylinder really affect its performance or behavior? On this episode of Engine Masters, we perform what may be the first ever back-to-back comparison of factory-oriented pistons against reverse-oriented ones.
