  • What era of racing is Craig Hampson referring to when he discusses the Lola IndyCar?

    -Craig Hampson is referring to the era of racing around 2005-2006, which was characterized by a more open rule set where teams could make significant changes to their cars, including suspension, aerodynamic components, and bodywork, compared to the more restricted 'spec' era of IndyCar racing that followed.

  • What was unique about the front wing setup on the Lola IndyCar?

    -The front wing setup on the Lola IndyCar featured pylon mounts that allowed more air to go underneath the car, and the ability to vary the front wing height depending on the car's ride height. They also used larger turning veins on the main plane trailing edge extensions to adjust the car's aerodynamic balance.

  • How did the Lola IndyCar's aerodynamics contribute to its performance?

    -The Lola IndyCar had an aerodynamic shape with specific design elements like the 'thumb print' air inlet for the underwing, which was tall and made the car less sensitive to front ride height. The car also featured vortex generators and adjustable rear wing end plates to optimize downforce and drag.

  • What was the significance of the mirrors used on the Lola IndyCar during the Indy 500?

    -The mirrors used on the Lola IndyCar during the Indy 500 were designed to reduce drag. Different shapes were tested in the wind tunnel to find the most aerodynamically efficient design, even saving as little as one pound of drag at 200 mph.

  • How did the Lola IndyCar's gearbox work during that era?

    -The Lola IndyCar used a manual sequential shift gearbox during that era. Drivers had to operate a shift lever with one hand, which could lead to physical strain, such as blisters, by the end of a race.

  • What was the engine configuration of the Lola IndyCar?

    -The Lola IndyCar was equipped with a V8, 2.65-liter engine that ran on methanol. It featured a single large turbocharger inside the bell housing, which compressed the air and supplied it to the engine.

  • How did the Lola IndyCar's suspension system differ from current IndyCar designs?

    -The Lola IndyCar's suspension system was developed entirely by the team and included aerodynamic push rods with a specific angle setting. The suspension used titanium-made components that were rigid to the chassis with a very low spring rate and no friction, which is different from the more standardized components used in current IndyCar designs.

  • What role did the 'Tire shelf gurney flaps' play in the Lola IndyCar's performance?

    -The 'Tire shelf gurney flaps' affected the airflow around the rear tire and over the top of the underwing. Teams experimented with these flaps to achieve different downforce levels suitable for various track types, from fast ovals to slower street courses.

  • How did the Lola IndyCar's dynamic dampers contribute to its handling?

    -The Lola IndyCar used four-way adjustable dynamic dampers (DSVs) that allowed for fine-tuning of the damping characteristics at high and low speeds. They also featured a spool valve that could change the damping shape, and a blow-off feature to flatten the damper curve over big bumps, improving the car's handling on various track conditions.

  • What does Craig Hampson consider the most rewarding aspect of working with the Lola IndyCar during that period?

    -Craig Hampson considers the ability to develop, modify, and get creative with the car parts as the most rewarding aspect. He enjoyed the freedom to come up with new ideas, realize them, and see them improve the car's performance on the track.
