Power Adders

Boost in a Box

While at LS Fest, we noticed several drivers spending a lot of time tuning their rides before hitting the track, dialing them in to try and gain an edge over the competition. This left us puzzled. If you’re looking for an edge, there’s no better way to optimize your performance with E85 than with a flex fuel system from Advanced Fuel Dynamics.


Auto manufacturers are constantly working to develop trucks that safely tow and haul more weight. However, the byproduct of high load capabilities is a rough unloaded ride. On a recent visit to J&D Performance, we found the crew beginning work on an Air Ride system for the owner of a 1999 F-350 two-wheel-drive dually. The owner of the truck was happy with its ability to tow and haul, thanks to Part-1’s addition of a full Banks Power Pack, but extremely unhappy with the truck’s ride when unloaded.


A Tough Act to Follow

Though clutches rank below power-adders on the desirability scale, they are every bit as important. In fact, you’d be better off not spending the time and money on a trick blower or turbo kit if you do not plan on upgrading the stock clutch assembly. Sure, it is possible on some applications to improve the performance of your motor without a clutch and pressure plate upgrade, but you can only take things so far. Eventually, the engine will let you know by racing to the moon when you least expect it. Your clutch will likely slip under full throttle, and most probably at the highest load. Better hope you have a rev limiter or things can really get ugly. But have no fear … Advanced Clutch Technology (ACT) has come up with a variety of effective combinations to cater to the needs of performance enthusiasts and racers.


It can be argued that one of the best mods you can make to an LS-based or Gen III motor is a camshaft change. With the number of aftermarket companies making many different types, a good cam can be found for anywhere from $300 to $1,000, depending upon what type of power you want to make and how sophisticated the cam package is. Because 99.99 percent of all vehicles on the road today are computer controlled, most aftermarket companies are able to suggest whether a new tune will be necessary or if the stock one will suffice. But with so many different options out there, it can be quite confusing as to which is the right one for you.



Like their diesel counterparts, gas-powered truck owners are always looking for ways to give their vehicles even more power and better mileage. To find out what kind of power options there are for gas-powered trucks, we went to J&D Performance in Ontario, California. We’ve seen what kind of power and performance the guys at J&D can make in a diesel-powered truck, so we figured we’d follow along as they wrenched more power out of a common gas-powered truck. After a quick phone call, we were set. The guys at J&D had a customer’s stock 1999 Ford F-350 dualie with a 6.8-liter V-10 ready for buildup. Here’s how it went.



Performance enthusiasts are a funny bunch. They all seem to agree that “as much as possible” is the correct answer when asked, “How much power do you want?” But they certainly
disagree about the best way to get there.


When you go looking to make huge power from your 5.0-liter Ford, the limiting factor will always be the weakest link in the chain. In the case of our supercharged 331 stroker buildup, the weakest link turned out to be the production block. Like most enthusiasts, we had no budget for a DART racing block or even a Ford Racing Sportsman block, but we decided to tempt fate nonetheless and go for a big power number on the dyno. Considering that the stock fuel-injected 5.0-liter was rated at a measly 225 hp, even a 300hp buildup would offer a welcome change in performance.

Action Packed

While the factory cast-iron four-barrel Q-Jet intake manifolds have performed admirably on literally thousands of GM applications—and if you are picking your engine from a used lot to use in a swap, it will likely be so equipped—every last one of them should be torn off the car and thrown in the dumpster.
