Engine Masters

Join us as our resident carb whisper, Steve Brule, takes us through all the tips and tricks you need to know to get your 4150 running its best on any engine. See it on this episode of Engine Masters, presented by AMSOIL!

Driven by lunacy as much as novelty, Dulcich is at it again with his slant-six tomfoolery. With goals of his 225ci monster powering a daily driver '68 Dart, Steve is putting four aftermarket intake manifolds to the test to see what will give him the most grunt.

We're talking an OEM used parts comparo, abundantly plentiful in the junkyards and classifieds. This debate has raged in the LS community for years, and we're here to show you the difference in power potential between a dime-a-dozen cathedral port and the "racier" rectangular ports found on the LS3.

The new Hemi has a new Hemi, but is it any better than the old new Hemi? That's right, we're battling two iterations of the 5.7 Gen III Hemi, the '03-08 vs. the '09-current, and we’re learning a TON in the process.

The Windsor family finally gets its turn at an intake shootout! This test mule is a Dart-based Windsor at 363ci with a solid roller cam and 7,100 rpm, and it’s just begging for the best single-plane manifold to breathe through. With offerings from Edelbrock, Trick Flow, Ford Racing, AFR, and SpeedMaster, we're sure to make our small Ford sing!

It's the age-old battle of power vs. price, but is it as simple as all that? Are you really giving up significant power by choosing a solid flat tappet, or is the extra power of the hydraulic worth every penny? Join us on this episode of Engine Masters presented by AMSOIL as we talk duration, lobe intensity, spring pressures, dollars, and horsepowers.

Are your cast manifolds enough to keep up with your turbo motor? And at what point should you be running proper headers? Those are the questions we're asking this time on Engine Masters, presented by AMSOIL.

Inspired by the learnings from Episode 43’s study on coolant temperature testing, we're going one step beyond icing down the manifold. This time on Engine Masters, presented by AMSOIL, we're deliberately heating and cooling our fuel to see the difference it makes to the tune and the power output of our Ultimate Average 383.

On this episode of Engine Masters, presented by AMSOIL, we've got an example of a 270cc Trick Flow unit to see if the Max Wedge style, with its bigger intake runners and more direct flow path, are really a worthwhile upgrade for YOUR typical street/strip big-block.

You've seen them all over. On vintage race cars, trophy trucks, motorcycles, and even-for some reason-street cars. They're header wraps, and manufacturers claim they not only reduce radiant heat, but create additional power through their scavenging effects and superior heat management. Is any of it true?? We'll find out on this episode of Engine Masters, presented by AMSOIL

So you've got an LS and you need to make a choice on an intake. Chances are high you're looking at some version of Holly's "Ram" Intakes, whether it's the long runner Hi-Ram, the Mid-Rise, the compact Lo-Ram, or the hood-clearance-friendly Ultra Lo-Ram. On this episode of Engine Masters, presented by AMSOIL, we line them up one by one on our 550 rectangle port headed 6.2-liter LS.

On this episode of Engine Masters, presented by AMSOIL, we not only show you the differences between these popular manifolds and test the power they make, but also how to get your LS running with a carb as easily as possible. We've got a lot of pulls to make, so let's get started.

Do exhaust cutouts really serve any purpose beyond rattling the drums out of passersby’s ears? Well, proponents have always claimed they make your car faster, but on this episode of Engine Masters, presented by AMSOIL, we see how they stack up against a full exhaust and a header extension behind our heavy-breathing 598-cubic-inch Big Block Chevy.

How much hidden power is lurking in your existing engine combination? We're here to show you how to find it without buying, changing, or upgrading a single component. On this episode of Engine Masters presented by AMSOIL, we use all the little tips and tricks we've learned over the seasons to super-tune every bit of remaining horsepower out of the 410ci Windsor from David's Disgustang.

No matter how many LS swaps are out there, the old-school SBC is still an absolute force in the marketplace. On this episode of Engine Masters presented by AMSOIL, we're bolting three of the lowest buck cylinder heads out there to our Ultimate Average 383 and making pulls for power!

This test is all about choosing the features you want and need on your carburetor, and how those features affect your horsepower and tunability. Do mechanical secondaries really make any more power than vacuum-power ones? Does a choke horn restrict inlet airflow? We'll help you decide what's best for your application on this episode of Engine Masters presented by AMSOIL.

We've tested single V-split pattern cams before on Engine Masters. Well, our findings have been challenged, and we're here for the science. The accustion: Our last test affected overlap, which supported torque. The solution: a retest using a split-pattern cam that has extra exhaust duration and no change in overlap from the single pattern.

Can too oil pressure also be robbing precious horsepower? To find out, we test three commonly ordered LS oil pumps in different volume and pressure configurations to find if oil pumps can in fact be enough of a rotational drag to affect your power production. Find out on this episode of Engine Masters presented by AMSOIL.

What do you do when your 800-horsepower 572 just won't get you consistent 8-second passes in your '31 Model A? Well, if you're David Freiburger, you strap it to the Westech Dyno to tune, poke, and swap at until you're at a comfortable 950+ hp. How do you get it there? Find out on this episode of Engine Masters presented by AMSOIL.

It's arguably the coolest carb configuration of all time. The 3x2 setup on the Six Pack was designed to supply part throttle economy on the center carb while the outside carbs kick in for power! On this episode of Engine Masters, we're shooting out three of the coolest vintage Six Pack designs to find out which is gimmick, which is greatness, and which makes the most power on our street 440.

With the power potential of E85 available only at limited gas stations, having the ability to run a blend of gasoline and E85 in your street car is a game changer. Credit the Flex Fuel Sensor. By sampling your fuel composition and adjusting fuel flow, you can not only run a mix of fuels, but make more and more power as you mix in more and more E85.

Do boost leaks really even matter? Can vacuum leaks make more power? You read those questions right. Come be surprised right along with us as we find power in unexpected places, and lose less than we'd expect in others, on this episode of Engine Masters presented by AMSOIL.

So you've decided to run nitrous on your EFI manifold and need to know how a wet system stacks up against a dry system. Does one make more power or give you more problems than the other? Which is easier to set up, and which requires more tuning? What does wet or dry even mena? Come learn the ins and outs nitrous in EFI manifolds on this episode of Engine Masters presented by AMSOIL.

We've been covering the battle of carburetor versus EFI as far back as episode 2 of Engine Masters. In this edition, multipoint EFI is getting its turn against the venerable Dominator. It's injectors versus jets, dry flow versus wet, and drivability versus horsepower on this episode of Engine Masters presented by AMSOIL.

One thousand horsepower is becoming all too common these days, and all too accessible. With such staggering numbers so well within reach, it's time we really looked into the differences between two ways to get there: a supercharger on a medium-sized mill, and natural aspiration atop a large-displacement. If you wanna go big, get informed. And you can do it right here on Engine Masters.
