CUP Race Technology, Volume 4
(click for larger image)

Published in March, 2013, this informative issue discusses NASCAR the sweeping changes incorporated in the Gen-6 body style and associated chassis upgrades, electronic refinements and improvements that have evolved from the first year of EFI usage, and lots more.

FEATURES:
1. GRID - An inside look at the more-than-skin-deep regulation changes for 2013; A look at the use of six-degree-of-freedom race simulators for driver refinement and for testing chassis setup; A chat with John Darby (NASCAR managing director of competition) about the transition to the Gen-6 car, and more.
2. INTERVIEW: McLaren and NASCAR....The First Year - Lawrence Butcher talks in depth with Peter van Manen, managing director at McLaren Electronics, supplier of the ECU for the Cup cars' EFI systems, discussing interesting topics regarding the introduction of EFI, the challenges, surprises, support, and rule-bending encountered during the first year of EFI in Cup.
3. PROFILE: Roush-Fenway's Nationwide Series Ford Mustang - Lawrence Butcher looks at the relationship between Ford Motor Company and Roush-Fenway Racing, chronicling the development of the Ford Mustang for the Nationwide series, including discussions of aerodynamics, chassis details, suspension, powertrain, and development of the racing platform.

EPI NOTE: please excuse the minor technical error in this article, in which the bore spacing of the FR-9 engine was reported as 4.125 inches. In fact, the bore spacing of the current Cup engines (FR-9, R-07, Toyota, and the {currently not used} Dodge R6P8) is 4.500 inches, and the typical bore-stroke dimensions are 4.185 x 3.250. All these current engines are purpose-built race engines, designed to optimize the provisions of NASCAR's strict and very specific rulebook.. The bore spacing of the predecessor Chevy and Dodge engines was 4.400 inches, and the predecesssor to the FR-9 (the Windsor) was 4.380 inches. When Toyota began racing in NASCAR, they had no pushrod V8 in production, so NASCAR allowed them to develop a clean-sheet V8 for NASCAR. That engine was designed around the 4.500 bore center dimension, with a substantially-raised camshaft centerline and a number of other design advantages. NASCAR incorporated many of the Toyota engine dimensions and features into their engine rulebook, then allowed the other manufacturers to design 2-valve pushrod V8's to take advantage of the same features.

4. INSIGHT: Data Logging - An in-depth look at the extent and methodologies which the Cup teams have developed to compensate for the prohibition against data acquisition under race conditions. This interesting article includes a discussion of gathering of data from various tracks to provide the input database for the racecar chassis and engine simulation activities (see NASCAR engine testing), as well as discussions of sensor technology, parameters measured, and data acquisition capabilities.
5. FOCUS: Electronics -Wiring systems in NASCAR have changed almost beyond recognition in the past couple of years, and the evolving technology is very interesting. This article discusses the system layout, the engine loom, various wiring and insulation materials, connectors, and evolutions in reliability engineering.
6. PROFILE: the 2013 Ford Fusion Cup Car - Lawrence Butcher recounts the development of the new Gen-6 Ford Fusion Sprint Cup car, which combines parity of performance with distinct brand identity, discussing the background of the Gen-6, the early days of the joint development effort, cooperation among the OEM's, dimensions, aerodynamic development, construction and testing.
7. FOCUS: Fuel Supply Systems - NASCAR fuel systems are far more sophisticated than many observers realize. This in-depth article provides a fascinating view into the requirements, technologies and implimentations involved in the current cars' fuel systems.
8. TECHNICAL REVIEW - An Eye to the Future - In spite of the tight regulations, the pace of development in NASCAR is relentless. This article looks at a few new components and technologies being considered for the medium-near term, including the application of nanotechnology to the engineering of fluids designed specifically to optimize performance in a given application (engine lubricants, transmission lubricants, hypoid-gear lubricants, etc), advances in stiffness and strength in braking systems, new structural materials

EPI NOTE: Please forgive the apples-to-oranges photos comparing the crushed-weld performance of 4130 tubing to the high-manganese DOCOL tubing. Even though the photos seem rigged, the bottom line is that the DOCOL does provide post-weld strength similar to 4130, with substantially greater ductility.

4. FOCUS: Corners - Although NASCAR Sprint Cup cars have their origins and roots in the 1960's, their alleged "simplicity" hides an unimaginable wealth of engineering detail in every component of the car. This is especially critical at each of the four corners. Lawrence Butcher reports on this technology.
5. INSIGHT: Fuel Injection - NASCAR has finally bid farewell to the trusty (and VERY evolved) four-barrel carburetor in CUP racing. Wayne Ward reports on the challenges that teams face and the advantages to be realized from the transition to this newer technology.
6. SPECIAL INVESTIGATION: Engineering the Driver - Ronn Langford presents an argument that the racecar driver can be treated as a set of reprogrammable and upgradable systems.
7. FOCUS: Brakes - 500 laps around a 1/2 mile bullring like Martinsville demands the ability to dissipate unimaginable amounts of energy-per-unit-time, decelerating these 3400+ pound cars from well over 110 mph to around 55 mph once every 9 seconds. The brake rotors glow red-hot behind the wheels, and the tire beads melt if the system is abused. Lawrence Butcher reports on the state-of-the-art in these essential braking systems.
