The quickest, fastest drag racing car in the world is the U.S. Army/Don Schumacher Racing, Top Fuel Dragster. Tony Schumacher, the Army car's driver, won the 2007 NHRA Top Fuel title (fourth in a row and fifth total), six of 25 events in '07, two of the first three in '08, leads in '08 points so far and holds both ends of the National Record. The world's quickest Funny Car is the Q Power/Pedregon Racing Chevy Impala SS. Owner/driver, Tony Pedregon, won the 2007 FC title (his second), four races in '07 and set the e.t. National Record. Both Schumacher and Pedregon chose the performance, reliability and durability of the Bill Miller Engineering Forged Aluminum Rod.

Most of the NHRA Nitro class racers use BME Forged Aluminum Connecting Rods. One reason for that? The people who work on the cars, like the crew of the US Army Top Fuel Dragster, know they can rely on BME's rock-solid reliability. Image: BME Ltd.

Not only did both 2007 NHRA POWERaid nitro class champions use BME Rods, but, 70% of the top 10 cars in Top Fuel and 100% of the top 10 in Funny Car had BME Rods in their engines.

 

The Top Fuel final round at the 2008 Winternationals was an all-BME affair. It pitted Cory McClanathan, in the FRAM Dragster, against Tony Schumacher in the U.S. Army Dragster. The two are team mates at Don Schumacher Racing and both use BME Forged Aluminum Connecting Rods in their engines. At the other end, it was Schumacher taking the win. Image:  Ron Bermudez

Other NHRA racers who chose BME are: in Top Fuel: Rod Fuller, Brandon Bernstein, Doug Herbert, Antron Brown, Cory McClenathan and Morgan Lucas and, in Funny Car: Robert Hight, Ron Capps, Melanie Troxel, Jack Beckman, Mike Ashley, John Force, Jim Head, Del Worsham, Ashley Force, Jeff Arend, Cruz Pedregon, and Tommy Johnson Jr.

The situation was the same in the International Hot Rod Association's two nitro classes. Both 2007 champions, Bruce Litton, Top Fuel, and Dale Creasy Jr., Funny Car, had Bill Miller Engineering Rods in their engines. BME Rods were in 60% of the top 5 IHRA TF cars and 80% of the top 5 Funny Cars.

One of the more successful drivers in Top Fuel is Doug Herbert. One reason he does well in the Snap-On Tools dragster is the BME Rods in its engine.  Image: Goodyear/Aaron Vandersommers.

One of the greatest blown-fuel drag racers in the history of the sport is Kenny Bernstein. Both as a driver, and now as a car owner with son, Brandon, behind the wheel, Kenny has used BME Forged Aluminum Rods. Image: Goodyear/Aaron Vandersommers.

Another blown-fuel racer who benefits from BME Rods' performance, reliability and durability is Ron Capps. His NAPA Dodge Charger R/T Funny Car is shown here in 2008 trim, at NHRA National Time Trials in January of '08. Image: Roger Richards/Don Schumacher Racing.

There's even a BME revolution in the A/Fuel Dragster class. A/FDs are unblown on nitro but are allowed to run as Top Alcohol Dragsters. '06 and '07 TAD Champion, Bill Reichert's A/FD uses BME Rods as does another injected-nitro competitor, Morgan Lucas, who, because he also runs Top Fuel, clearly, can't get enough of nitromethane or BME parts.

Other connecting rod makers may brag, but when you look at the facts; it’s clear: BME Forged Aluminum Connecting Rods totally dominate nitro-fueled drag racing, no matter what sanctioning body, what class or whether the engine is blown or unblown.
 

While Bill Miller Engineering Forged Aluminum Rods are available in versions engineered for supercharged engines on fuel, they've inspired different BME Rod configurations designed and priced for use in other drag race applications, such as: blown-alcohol, Pro Stock and Comp Eliminator. There are even BME Rods for very high performance street engines.

1) Bill Miller Engineering Aluminum Rods consistently outperform and outlast all other aluminum connecting rods. 2) In 32 years of building the finest aluminum rods available, BME has earned for a reputation innovative technology and continuous improvement.  3) BME puts overriding emphasis on quality through testing, inspection and manufacturing process controls. 4) Bill Miller has raced a Top Fuel car since the early 1980s. There is no better way to find out what it takes to make the best drag race connecting rod in the world than to regularly test it in your own Top Fueler. 5) BME Rods are made-in-America with the finest materials and the best workmanship of any racing connecting rod available today.

Bill Miller Engineering is the only manufacturer of aluminum connecting rods which develops and tests its products in its own Top Fuel Dragster.

For a given part, compared to 7075-T6, this newer type of aluminum provides an average, 15% increase in tensile and yield strength along with equal or better elongation and other mechanical qualities with, most importantly–no increase in weight. In short, with Bill Miller Engineering rods, racers get longer fatigue life for their money, but no extra weight.     The Truth about Billets The Aluminum Association, a trade organization which sets industry standards, defines a “billet” as a "hot-worked, semifinished product suitable for subsequent working." Other manufacturers sell “billet” aluminum connecting rods. Unfortunately, BME’s competitors neglect to mention that the billets they use in making their rods are cut out of thick pieces of flat stock--ordinary aluminum plates. In this era of lightweight engine components, exceptional fatigue life comes only from advanced technology and superior materials. Bill Miller Engineering has combined the outstanding metallurgy in its advanced aluminum alloy with the advantages of the die forging process to produce a forged aluminum connecting rod which beats the "billets" under real world racing conditions. Proof of that is 80% of the top NHRA and IHRA Top Fuel and Funny Car racers using BME Rods and the Bill Miller Engineering Aluminum Rod winning 35 NHRA and IHRA championships in the last 23 years. No other aluminum rod manufacturer even comes close to that record.

The first step in making a BME Forged Aluminum Rod, forging the Rod's basic structure from a chunk of aerospace-quality aluminum. A half-a-dozen raw BME forgings. They'll sit for a while then get moved to the machining facility. Don't touch! They're still hot.

Following extrusion, BME’s die-forging process shapes the aluminum and compresses its grain structure by heating it to 700°F then applying pressure of 2200 tons. Compared to rods which are simply cut out of flat stock, BME’s forging process: 1) significantly enhances grain flow and increases grain density. 2) forces the grain of the extrusion into the connecting rod shape and, more importantly, aligns that part of the grain which makes up the rod's tapered beam with the direction of highest stress the rod will sustain in a running engine and, 3) forces the grain around the rod bearing bore, creating a "hoop stress" phenomenon that provides maximum strength for the limited cross-section available at the rod’s big end.

In the early 1990s, during research into the strength of connecting rod materials which eventually resulted in Bill Miller Engineering's switch to a different type of aluminum, Alcoa conducted fatigue life comparison tests which showed failures are caused chiefly by stress due to severed grains and improper gain direction. With a connecting rod machined from a plate, any machining severs grain ends. If this machining is done to critical sections of the rod, such as the beam or the big end, severed grain ends weaken the rod. If remaining uncut grains are not aligned in the proper direction, the rod will be further weakened.

A BME Rod’s taper, because it results from the forging process rather than machining, does not expose grain ends. In a conventional aluminum rod, cut from flat-stock; grain length is cut off by the rod bearing bore, again, exposing the grain ends. In contrast, the forging process used by Bill Miller Engineering forces the grain around that bore. Better grain flow, higher density, grain aligned with the direction of most stress, tapering which does not cut the grain and big end grain formed around the rod bearing bore are just a few reasons for a BME Rod’s exceptionally long fatigue life.

BME Rods are available in a variety of styles to fit the following engines: Chrysler 426 Hemi, 440 Wedge and 340 A-Block, Small- and Big-Block Chevrolets and Big-Block Pontiac. Also, some Ford rods are available by special order. For more information, see our rod prices page or call BME.

The Only Streetable Aluminum Rod Urban legends abound in the gearhead community. One is: aluminum connecting rods don't work in street engines. Prior to the mid-'70s, that might have been true, however, introduction of the Bill Miller Engineering Forged Aluminum Connecting Rod in 1975 provided a glaring exception to that myth. The BME Rod has good durability in high-end, high-power, street/strip or hot street engines because it is die-forged, rather than cut out of an aluminum plate. Bill Miller Engineering's unique, high-strength, aluminum alloy further enhances fatigue strength such that the potential durability of BME Rod rivals that of many forged steel rods and exceeds that of a few.

About 20 years ago, a few resourceful engine builders, led by H-O Racing's, Ken Crocie, began using BME Rods in high-end, very-high-performance street engines. Crocie, a racing and street/strip Pontiac V8 specialist, faced with a shortage of acceptable steel rods for Pontiacs, began to use BME Aluminum Rods. While a few other engine builders have followed Crocie's lead, admittedly, use of the Bill MIller Engineering Rod in street engines has not been widespread, but that's only because of its higher cost and the stubborn belief that any aluminum rod is unsuitable for street use.

"In a street application, using the aluminum rod is a no brainer," BME President, Bill Miller recently said in an interview with an automotive magazine. "I don't know exactly how the myth that aluminum rods can't be used on the street got started, but I'll guess that early manufacturers of aluminum rods, back in the 60s and early-70s, weren't making them using the forging process we're using. With the material we've got and they way we manufacture the connecting rods, they'll live a couple hundred thousand miles on the street because a street application is, for the most part, low load. You gotta understand, our basic Aluminum Rod is made for 10,000 rpm and 800-hp. The design criteria for the connecting rod is way overkill for what it's gonna see on the street. We been running aluminum rods on the street for 20 years."

Why build a street engine with BME Rods? One reason is the "cool factor." Bill Miller Engineering Rods are unique, high-end racing parts and there always will be people who spend extra money to have the same rods in their engine as Tony Schumacher or John Force puts in his. More importantly, there are practical reasons for using BME Rods—the same reasons racers use them: less reciprocating and rotating mass due to their comparative lightness. That allows the engine to accelerate quicker and make more power as it does so. Lighter rods also improve throttle response and allow the engine to run reliably at a higher rpm than it could with steel rods.

Standard BME Forged Aluminum Connecting Rods for most production Chevrolet, Chrysler and Pontiac V8s are reliable replacements for steel rods in engines of up to 800 horsepower. Aluminum Rods for some Ford V8s of similar power output are available on special order. A Big-Block Chevrolet style, Pro Stock rod, good to 1200-hp, is, also, available. If the application is a Chrysler 426 Hemi or big-block "wedge", BME's blown-alcohol rods can be used at levels well over 2000-hp and have outstanding reliability/durability.

And What About Bolts?

In keeping with BME's ruthless pursuit of quality, Bill Miller installs nothing but the finest cap screw type rod bolts in his Connecting Rods. These bolts are manufactured to BME's specifications by fastener manufacturer, Automotive Racing Products (ARP).

BME/ARP Rod Bolts come in two varieties. The bolts in most BME Rods are made of 8740 chromium-molybdenum (chrome-moly) steel, a quenched and tempered steel with a tensile strength of between 180,000 and 210,000 psi. The bolts used in rods Bill Miller sells for supercharged drag race applications are made of a special hybrid alloy called "ARP2000" which has a tensile strength of 215,000-220,000 psi. BME's bolts made of this ARP-exclusive material receive a special, proprietary heat-treating process designed by BME specifically for rod bolts used in blown-fuel drag race engines.

ARP 2000 steel, rolled threads and a special, BME-designed heat-treating process makes the bolts in a BME Aluminum Rod the strongest in the industry.

Both types of BME/ARP Rod Bolts are CNC-machined. They are heat-treated in vertical racks which ensures complete, 360-deg. penetration. These bolts have rolled threads but the thread rolling is done after heat-treating which provides up to 10-times more fatigue life than bolts with threads rolled before heat-treating. Needless to say, when you buy a BME Aluminum Rod, the last thing you need to worry about are rod bolts..
