The Eagles have
landed at the Petersen
The author recently visited the Petersen Automotive Museum
in Los Angeles and toured one of the featured exhibits “The Eagles have landed”
in the gallery funded by the author’s friend and single engine wheel-driven
Land Speed Record holder Charles Nearburg. The exhibit focuses on the cars and
accomplishments of Southern California racing legend Dan Gurney and we will take a look at several of the open-wheel cars on display.
From left to right – the All-American Racing (AAR)
Gurney-Weslake V-12 Grand Prix car, the 1968 AAR Gurney-Weslake Ford powered
Indianapolis car, and the AAR-modified Mclaren “McEagle” Can-Am car.
From left to right- the 1971 turbocharged Offenhauser
powered Eagle, the 1975 turbocharged Offenhauser powered Eagle, and the 1977
Eagle SCCA Formula Ford.
1968 Eagle
Dan Gurney only drove the 1968 AAR Eagle in five United
States Auto Club (USAC) races; four road course races and the Indianapolis International
500-mile Sweepstakes. The Eagle’s season
started at the Stardust 150 at the windswept Stardust international Raceway outside
Las Vegas Nevada. Gurney qualified his new Eagle powered by the 303-cubic inch
Ford stock block V-8 engine fitted with aluminum Gurney-Weslake cylinder heads
for the pole position, but the front suspension of the car broke before Dan
took the green flag.
At the Indianapolis Motor Speedway, Gurney qualified the
Eagle in the tenth position with a four-lap average nearly five miles per hour slower
than Joe Leonard’s pole-winning STP Lotus 56 turbine. During the race, Gurney
never led but brought the Eagle home in in second place followed by his
teammate Denis Hulme in fourth place. Two weeks later on June 15 1968, at the
2-1/2 mile Mosport road course in Canada, Gurney and the Eagle started from the
pole position for both the 98-mile heat races. Gurney totally dominated the
races, and led all 80 laps and won both the heat races.
Gurney and the Eagle did not appear in other 1968 USAC races
until the season ending Rex Mays 300 at the Riverside International Raceway.
For the second year in a row, Gurney qualified for the pole position and won
the Rex Mays 300 for the second year in a row. Unlike the previous years,
Gurney and the Eagle were totally dominant, as he led all 112 laps around the winding
2.6 mile road course. In retrospect, the
1968 AAR Eagle has to be considered a success; three race wins and one second
place in a limited five-race season
1971 Eagle
Dan Gurney retired as a driver in 1970, and he later
admitted that the transition was difficult at times as rather a seat of the
pants engineering evaluation, Gurney had to rely on feedback from new AAR
driver. Bobby Unser. The 1971 Eagle
Indianapolis car was a revision of the 1970 Eagle fitted with a turbocharged
Offenhauser power plant. The 1971 Eagle was brutally fast and Unser was the
fastest qualifier at seven races and set four new lap records.
Reliability proved to be a problem and between mechanical
failures and crashes, Unser only finished five races on the 12-race Marlboro
Championship Trail but in two of those races, at Trenton New Jersey and the Milwaukee
Mile Unser emerged victorious. In August at the Milwaukee Mile, Bobby led all
but nine laps, and at the Marlboro 300 held in October at Trenton, Bobby led
the first 70 laps before he pitted and turned the led over to his brother Al
for the next ten laps before Bobby in the #2 Olsonite Eagle took back the lead
and led the rest of the way.
1981 Eagle
For 1980, Gurney together with All American Racers designers
Trevor Harris and John Ward created an amazing design that used the Boundary
Layer Adhesion Technology (BLAT) ground effects system. Instead of using tunnels
underneath the car as with other designs the BLAT concept used a twin vortex
generating shape at the trailing edge of the rear bodywork. The routing of the naturally
aspirated aluminum block 358-cubic inch Chevrolet engine exhaust system added
further energy and downforce to the airflow.
By 1981 BLAT had reached its ultimate development with this
Pepsi Challenger and driven by veteran Mike Mosely qualified at 197.141 miles
per hour (MPH) to start in the middle of the front row for the Indianapolis
500-mile race. While former Eagle pilot Bobby Unser streaked away from the pole
position on his way to a disputed victory, Mosley was the first car sidelined
after just 16 laps with an oil radiator leak.
A week later at the Gould Rex Mays Classic, Mosely and the
Eagle suffered an early engine problem and failed to make a time trial run, so
the Pepsi Challenger started 25th in the 26-car field. Mosley worked his way
forward through the field and took the lead on lap 106 and he built up more
than a one-lap advantage over second place Kevin Cogan when the checkered flag
dropped after 150 laps around the one-mile oval.
Sadly the Milwaukee race was the high water mark for the
Eagle’s 1981 season, as in its remaining three appearances, the car was
sidelined with mechanical troubles. Later in an ironic turn events the
Championship Auto Racing Teams (CART) organization, which Gurney had helped, found
after displeasure with USAC rule-making outlawed both the BLAT concept and the
use of aluminum stock-block engines.
"The Eagles have landed" exhibit which includes the historic Moet champagne bottle from the 1967 24 hours of LeMans and Gurney's Bell ground-breaking full-face helmet worn in the 1969 Indianapolis 500-mile race continues at the Petersen
Automotive Museum through January 10 2018
