Resident carb whisperer Steve Brule walks through all the tips and tricks you need to know to get your 4150 running its best on any engine.Subscribe to discovery+ or Max
- S7 E2 - Slant-Six Manifold Shootout!!July 22, 202227minDriven 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 puts four aftermarket intake manifolds to the test to see which gives him the most grunt.Subscribe to discovery+ or Max
- S7 E3 - Rectangle vs. Cathedral PortsJuly 22, 202222minA debate has raged in the LS community for years about the difference between dime-a-dozen cathedral ports and the rectangular ports found on the LS3. The rectangles have bigger intake ports, flow numbers, valves and chambers, but what does it add up to?Subscribe to discovery+ or Max
- S7 E4 - The Battle of the Gen III Hemis!!August 5, 202238minWe're battling two iterations of the 5.7 III Hemi, and we're learning a TON in the process. With an eye toward engine-swap simplicity, we've stuffed both with the biggest cams they can handle and managed fuel and spark in the most affordable way possible.Subscribe to discovery+ or Max
- S7 E5 - SBF Intake Shootout!September 30, 202225minThe Windsor family gets its turn at an intake shootout! This Windsor is just begging for the best single-plane manifold to breathe through, and offerings from Edelbrock, Trick Flow, Ford Racing, AFR and SpeedMaster are sure to make our small Ford sing!Subscribe to discovery+ or Max
- S7 E6 - Solid Lifter Cam ComparoAugust 12, 202227minIt's the age-old battle of power vs. price, but is it that simple? Are you really giving up power by choosing a solid flat tappet, or is the extra power of the hydraulic worth it? We talk duration, lobe intensity, spring pressures, dollars and horsepower.Subscribe to discovery+ or Max
- S7 E7 - Manifolds or Headers?August 12, 202229minAre cast manifolds enough to keep up with your turbo motor? And at what point should you run proper headers? We're running our LS with factory exhaust manifolds and again with turbo headers to show the difference in boost, back pressure and horsepower.Subscribe to discovery+ or Max
- S7 E8 - Does Fuel Temperature Matter?August 26, 202230minOne fuel, two fuel, hot fuel, cool fuel. Inspired by their previous study of coolant-temperature testing, the guys go one step beyond icing down the manifold, deliberately heating and cooling fuel to see the difference it makes.Subscribe to discovery+ or Max
- S7 E9 - Measuring the Max WedgeAugust 26, 202223minThe Mopar Max Wedge head was once considered all but unobtanium, but the aftermarket has come to the rescue. We test a 270cc Trick Flow unit to see if the Max Wedge style, with its bigger intake runners and more direct flow path, is a worthwhile upgrade.Subscribe to discovery+ or Max
- S7 E10 - Do Header Wraps Work?September 2, 202226minManufacturers claim header wraps not only reduce radiant heat, but create more power through their scavenging effects and heat management. Is it true? We'll find out as we test painted, ceramic-coated and wrapped headers on our Ultimate Average 383.Subscribe to discovery+ or Max
- S7 E11 - Which Ram? All the Rams?!September 2, 202228minSo you've got an LS and you need to make a choice on an intake. The guys line up a bunch of Holley's "Ram" intakes one-by-one on their 550 rectangle-port-headed 6.2-liter LS to help you decide which power curve is best for you.Subscribe to discovery+ or Max
- S7 E12 - Manifold ShootoutSeptember 16, 202237minFor folks out there running a carburetor on the new-fangled LS, we have six manifolds to sandwich between our old-school carb and our new-school 6.0 LS. We show you the differences between the manifolds and how to easily get your LS running with a carb.Subscribe to discovery+ or Max
- S7 E13 - Exhaust CutoutsSeptember 23, 202223minDo exhaust cutouts serve any purpose beyond rattling passersby's eardrums? Proponents claim they make your car faster, but we see how they stack up against a full exhaust and a header extension behind our heavy-breathing 598-cubic-inch Big Block Chevy.Subscribe to discovery+ or Max
- S7 E14 - Every Trick in the BookJanuary 20, 202322minThe crew shows how to unlock the power lurking in an existing engine combination without buying, changing or upgrading a single component. They use tricks they've learned over the years to tune every HP out of the 410 Windsor from David's Disgustang.Subscribe to discovery+ or Max
- S7 E15 - Low Buck SBC Head ShootoutJanuary 20, 202323minNo matter how many LS swaps are out there, the old-school SBC is still an absolute force in the marketplace. The guys bolt three of the lowest-buck cylinder heads out there to their Ultimate Average 383 and make pulls for power.Subscribe to discovery+ or Max
- S7 E16 - Pick-a-Carb ShootoutJanuary 27, 202339minThis test is all about choosing the features you want and need on a carburetor, and how those features affect horsepower and tunability. Do mechanical secondaries really make any more power than vacuum-power ones? Does a choke horn restrict inlet airflow?Subscribe to discovery+ or Max
- S7 E17 - Single Pattern vs. SplitFebruary 17, 202322minSame test, new twist. We've tested single V-split pattern cams before and concluded that a split pattern can increase top-end power without necessarily affecting bottom-end torque. Well, our findings have been challenged, and we're here for the science.Subscribe to discovery+ or Max
- S7 E18 - Oil Pumps for Power?!February 3, 202322minWe all know oil pressure is critical. Not enough can leave you broken, and too much can cause leaks. But can too much also be robbing precious horsepower? To find out, the guys test three LS oil pumps in different volume and pressure configurations.Subscribe to discovery+ or Max
- S7 E19 - Quest for F-Rod GreatnessFebruary 3, 202322minWhat do you do when your 800-horsepower 572 just won't get you consistent eight-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+ horsepower.Subscribe to discovery+ or Max
- S7 E20 - Six Pack Shootout!February 10, 202322minThe six pack was designed to supply part-throttle economy to the center while the outside carbs kick in for power. The guys shoot out three six pack designs to find out which is gimmick, which is greatness, and which makes the most power on a street 440.Subscribe to discovery+ or Max
- S7 E21 - Magic of the Flex Fuel SensorFebruary 10, 202322minWith the power potential of E85 available only at limited stations, the ability to run a blend of gas and E85 is a game changer. Credit the flex fuel sensor, which samples fuel composition and adjusts fuel flow, making more power as you mix in more E85.Subscribe to discovery+ or Max
- S7 E22 - The Leaker EpisodeFebruary 17, 202322minDo 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.Subscribe to discovery+ or Max
- S7 E23 - Wet vs. Dry NitrousFebruary 24, 202322minSo 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?Subscribe to discovery+ or Max
- S7 E24 - Carb v. EFI Multipoint EditionMarch 3, 202322minWe've covered the battle of carburetor versus EFI as far back as Episode 2 of Engine Masters. This time, multipoint EFI gets its turn against the venerable Dominator. It's injectors versus jets, dry flow versus wet, and drivability versus horsepower.Subscribe to discovery+ or Max
- S7 E25 - Blown v. NAMarch 10, 202322minOne thousand horsepower is all too common these days and all too accessible. With these numbers well within reach, it's time we looked into two ways to get there: a supercharger on a medium-sized mill; and natural aspiration atop large-displacement.Subscribe to discovery+ or Max
