THE PARTICULAR VOLKSWAGEN TDI-POWERED, 237-MPH STREAMLINER

Land speed racing is one kind of motorsport that, up until modern times, acquired never been regularly frequented simply by diesel-powered vehicles. However , over the course of the final two decades the rapid rate associated with advancements occurring in diesel technologies undoubtedly piqued the interest of many property speed enthusiasts. As a result, we’ve noticed a variety of compression-ignition engines infiltrate this particular prestigious sport. How about the Cummins-powered Dodge Dakota from Banks gave the “Sidewinder, ” the Duramax-propelled “Mormon Missile, ” or the record-holding, twin-engine’d JCB Dieselmax streamliner? Plus who could forget the 215-mph “Rocket Ranger” furnished with a Hypermax-built six. 0L Power Stroke…

A 147, 000-mile, totally unmolested 5. 0L V-10 TDI out of an ’05 model season Touareg lives in the engine compartment from the Adler brother’s streamliner. The only inner trip into the engine entailed installing a set of bench-tested unit injectors furnished with Fratelli Bosio Race 783 valve. Custom, freer-flowing exhaust manifolds path exhaust to the turbochargers, while double air-to-water intercoolers keep intake plus exhaust gas temperature in check through the course of the streamliner’s long training course runs.

After toasting both OE variable geometry turbos due to overspeeding, a pair of these fixed geometry devices feed the engine a fairly conventional amount of boost. Originally manufactured by BorgWarner and modified by Apex Overall performance Turbochargers of Oxnard, California, every K16 unit features a titanium air compressor wheel with a 44mm inducer as well as a 63mm exducer, and a 55/46mm (inducer/exducer) turbine wheel. Both units furthermore make use of internal wastegates, controlled simply by TurboSmart actuators.

Early on in the engine-to-chassis integration process, Andy Fabbro plus Gabe Scott of AG Autowerks realized that retaining key portions from the factory engine wiring harness (and its respective controllers) would conserve considerable time. Thanks to repurposing the manufacturer wiring harnesses, the streamliner believes it’s an ’05 Touareg—and truth be told, the remote keyless entry still functions. Here, you can see the OEM cabling harness spanning the length of the motor and wrapped in a protective temperature shield. Also notice the Kerma TDI Q Pro tuner in the midst of posting a calibration to the ECM, and also the top-mounted aluminum radiator.

V-10 TDI?

Without query, some truly unique means of propulsion were used in diesel-powered land speed automobiles. Recently, we came across what is probably the most unlikely candidate we’ve actually seen. It’s a streamliner known as Double Eagle, and it’s Vw TDI powered—but not by among the mini-engines that typically come to mind if you picture the VW badge. Rather, brothers Davidson and Doug Adler campaign the unit-injected 5. 0L V-10 that once graced the particular Volkswagen Touareg. Few knew concerning the 5. 0L when it was accessible in the midsize SUV and even less know anything about it now—but up to now it’s proven to be a solid foundation in order to pursue records with.

Joining up with AG Autowerks

Because the owners of Adler Land Rate in Southern California, the Adlers—along with Frank Klos—found themselves knee-deep in the process of building a streamliner framework in 2011. Looking to build something exclusive, they sourced a Volkswagen a few. 0L V-6 TDI and contacted Andy Fabbro and Gabe Scott of AG Autowerks—a shop that will specializes in all things VW—about juicing up enough to make them competitive from the salt. After advising all of them that the late V-10 diesel will be a much better candidate to start with, the Adlers wasted no time sourcing a takeout engine and transmission. “A 7 days later, they had a V-10, ” Fabbro remembered. “And I believed to myself: ‘Now we’ve got the platform we can work with. ’”

The set of K16 turbochargers send exhaust away dual, rear-facing stacks. Combined general boost for the twin-turbo configuration investigations in at 24 psi—well inside the system’s 30-psi safe zone. We are sure the V-10’s factory mind bolts appreciate seeing the fairly low boost number, and there is absolutely no reason to believe each charger is not being kept happily within the map. To survive the extreme warmth produced by the turbos, the motor cover is made of formed aluminum.

This is exactly what the 5. 0L V-10 TDI employed in the Adler brother’s streamliner came out of: a Volkswagen Touareg. Through ’04 to ‘08, the middle size SUV could be optioned with the V-10 diesel in North America, with the exception of the particular ’05 model year. Stickered from $70, 000 and on the brink of failing to meet stricter Oughout. S. emissions regulations, the V-10 quietly disappeared from the Touareg’s rates in ‘09.

In factory cut, the 5. 0L V-10 TDI belted out an underrated 310 hp at 3, 750 rpm and 553 lb-ft of torque on 2, 000 rpm. The 90-degree, 300 ci mill’s compression proportion checked in at 18. zero: 1 and fuel delivery arrived by way of cam-driven, unit injection. Gave the Pumpe Duse (PD) program, it produced a peak shot pressure of 29, 700 psi. A twin-turbo configuration placed the variable geometry Garrett GT1852V in the back of each bank—effectively making the Touareg more of a 5, 800-pound skyrocket ship than an unassuming loved ones truckster.

As is par for the program among streamliners, the Double Eagle’s long, lean shape better is similar to a high-velocity bullet than it will a race car. All reddish colored panels on Double Eagle are produced from composite reinforced fiberglass pulled through molds of Ron Main’s Entire world Record-holding, flathead-powered “Flatfire” streamliner. Rather than glass, Lexan polycarbonate is employed, that is a Southern California Timing Association (SCTA) requirement. Tandem 22x4x17-inch Goodyear Skull cap Front Runners and rear 28x5x15-inch Goodyear Eagles are fully surrounded and rated for better than three hundred mph.

Powertrain Incorporation

Once the Double Eagle task was officially underway, all framework, body, and suspension changes had been handled by Adler Land Swiftness, while the folks at AG Autowerks were tasked with integrating the particular engine. While mounting the V-10 mill was easy enough, the particular electronic side proved much more time intensive. With the high-tech TDI requiring numerous lines of communication between the various control modules, the original purpose to built a custom cabling harness was quickly aborted. Rather, most of the engine’s original wiring control remains. In order to effectively control the particular Aisin transmission, the factory TCM was reused as well. After isolating the OEM transfer case from your transmission, the act of delivering power to the rear, quick-change axle required an one-off combination of a broached sleeve incorporating a standard U-joint plus an 18- inch long drive shaft.

The particular truss-style chassis (and safety case) is constructed of 1 . 75-inch thick walls mild steel, contiguous length tubes from bow to stern. The particular chassis also incorporates in-line-tandem guiding controlled via Schroeder steering container and bell crank. The cover, fabricated by Specialty Aircraft, had been another piece handed down from Ron Main to the Adlers, which they additional an aluminum perimeter frame in order to.

While strapped into his 5-point, RCI harness and piloting this particular bullet train across the vast room that is the Bonneville Salt Flats, operater Davidson Adler keeps an eye upon two very important engine vitals: EGT and coolant temp. Unlike pull racing, land speed records need long, sustained intervals of complete throttle acceleration. The six or even seven seconds your pyrometer can be buried during a quarter-mile race will not hurt anything—but do it for an whole minute and you’ve got serious troubles. To keep the [factory] pistons from melting, Davidson great crew like to see no more than one, 400 degrees F worth associated with EGT—and the streamliner has been fine-tined to run no hotter than this particular pre-established threshold. To keep the head mechanical seals alive, the crew also favors to see water temp remain in the particular 195-to-215-degree range.

This is the record-setting period slip that was handed to Davidson Adler and his team at the 31st annual World of Speed competition on September 17, 2017. Not just was the world record for a five. 0L or smaller diesel-powered automobile achieved, but the 237-mph exit velocity earned the Double Eagle the particular honor of being the fastest Vw racer currently in existence.

The 795 LB-FT Package

Though the 147, 000-mile motor has been left completely alone, the particular factory injectors were replaced using a set of flow-tested units equipped with Bosio Race 783 nozzles from Kerma TDI. Matching the added encouraging are a pair of 44mm, fixed angles BorgWarner K16 turbos built simply by Apex Performance Turbochargers. The increased air is dramatically cooled through dual water-to-air intercoolers before getting into the engine. All ECM plus TCM tweaks are performed simply by Kerma TDI, and the streamliner’s greatest tune sends 795 lb-ft torque capacity to the wheels.

World’s Fastest VW Racer

After a period of trial and error that integrated a failed oil cooler, 2 blown factory turbochargers, and a most of 201 mph, the Double Skull cap team set a record on Sept 17, 2017. While participating in the particular 31st annual World of Velocity event at the Bonneville Salt Condominiums, Davidson Adler piloted the one-ofa- kind streamliner to a 237-mph leave speed— making it the fastest Vw racer in the world. Even more promising was your fact that a mild ECM melody was used on the record-setting pass—indicative that the powertrain has a lot more still left in it.

Looking to the near future, it’s been rumored that the Dual Eagle team plans to go after Bonneville’s diesel-powered streamliner land quickness record of 317 mph, that is currently held by the JCB Dieselmax streamliner. As you can imagine, picking up at least an additional 80 mph won’t be a simple feat, but it’s one that most parties involved believe can be achieved.

So what’s it love to go 237 mph? According to operater Davidson Adler, it’s “oddly relaxed. ” “Only wind noise… plenty of wind noise. The speed is deceptive, but I imagine it’s such as going fast in a speedboat upon smooth water, ” he informed us. In fact , “on our first run this year at World associated with Speed, we learned that our GPS NAVIGATION was broken roughly four mins before we were going to push away from to start. We hadn’t done the particular math for reference to the tach, so we figured we’d just view our gauges, not push everything too hard, and be comfortable. At the end of the particular run, I couldn’t tell you merely did 160 or 240 with. Well, 227 mph was the average over the measured mile. To express we were happy with that would be an tiefstapelei! ”

Aiming to the Future

According to Andy Fabbro, 250 to 255 with is achievable in the streamliner’s present state. However , a much bigger program may be in the works: becoming the particular world’s fastest diesel streamliner. Becoming that Double Eagle’s chassis will be loosely based on a design that is already gone more than 400 your, there is no reason to doubt they have what it takes to give the current Bonneville report holder of 317 mph the run for its money.
