26. Tunnel Ram Battle

December 22, 2022

As a longtime promoter of tunnel-ram greatness, Freiburger is often asked about running a four-barrel carb versus dual quads on the tunnel ram. Finally, he answers with a setup for guys who are all about the look, presence and glory of the tunnel ram.

25. Blown v. NA

December 15, 2022

One 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.

24. Carb v. EFI Multipoint Edition

December 8, 2022

We'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.

23. Wet vs. Dry Nitrous

December 1, 2022

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?

22. The Leaker Episode

November 24, 2022

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.

21. Magic of the Flex Fuel Sensor

November 17, 2022

With 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.

19. Quest for F-Rod Greatness

November 4, 2022

What 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.

18. Oil Pumps for Power?!

October 28, 2022

We 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.

17. Single Pattern vs. Split

October 21, 2022

Same 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.

10. Do Header Wraps Work?

June 3, 2022

Auto parts testing and engine-to-engine shootouts; developed from the popular Engine Masters Challenge and hosted by Steve Dulcich of Engine Masters magazine, David Freiburger of Roadkill, and Steve Brule of Westech Performance Group.

May 24, 2022

The Mopar Max Wedge head was once considered all but unobtanium, but the aftermarket has come to the rescue; testing a 270cc Trick Flow unit to see if the Max Wedge style, with its bigger intake runners and direct flow path, is a worthwhile upgrade.

Are 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.

6. Solid Lifter Cam Comparo

May 3, 2022

It's the age-old battle of power vs. price; investigating whether choosing a solid flat tappet sacrifices power and whether the extra power of the hydraulic is worth it; talking duration, lobe intensity, spring pressures, dollars and horsepower.

April 22, 2022

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 III Hemi, the '03-08 vs. the '09-current, and we're learning a TON in the process.

110. SBF Intake Shootout!

April 29, 2022

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!
