Brock Cobra Daytona Coupe - Circuit Le Sarthe - Le Mans Classic - Nadine Geary
One and a half lap of Circuit Le Sarthe, Le Mans at a fairly conservative
pace due to changable weather conditions and traffic. The Brock Cobra
Daytona Coupe hits 170 MPH/270 KMH on the straights. Driven by Nadine Geary
at Le Mans Classic 7th July 2012. Not the best quality video, but you get
the idea.....Immense fun, and a fulfilled dream for Nadine driving this car
on this iconic circuit.

Formula 1 - Honda RA107 Windtunnel Test - Nadine Geary
The Honda RA107 in MIRA's windtunnel. Pretty rare footage, as full scale
modern Formula One cars are rarely used for this purpose these days. Many

BMW E46 M3 Race Car Shaker Rig Suspension Testing
The Turner Motorsport BMW E46 M3 race cars get a suspension "shake down" --
literally! This computerized setup, commonly known in the business as a
"shaker rig" is a sophisticated tool used to simulate suspension dynamics.
This testing is part of the preparation of the cars for the 2009 Grand-Am
KONI Sports Car race series. Look for these cars, in their full Turner
Motorsport race livery in 2009, or visit our website
www.TurnerMotorsport.com for more info, including photos, videos, race
stats and more.
1 Ohlins DFV
With the use of 3 channels on both the compression and extension cycle
sides, the control of the attenuation of the moment (movement?) at the
beginning of the shock stroke is possible.
Before the main valve starts to move, the sub-valve releases oil pressure
for an overall comfortable ride.
With the sub-valve on the compression cycle side, the instant wheel goes
over the bump the sub-valve starts to work to absorb the impact resulting
in a comfortable ride.
However, once the vehicle starts to come off the bump to a flat surface and
the sub-valve is not present, it relies on the main valve only. The result
of this is that the impact of the wheel rolling off the bump increases. In
other words, bad ride quality.
This is why it is important to have the sub-valves on both sides of the
cycles. Less impact means a comfortable ride

Racer's Edge 996 on 7-post shaker rig
This video is of the Racer's Edge Porsche 996 on the 7-post shaker table
rig at Ohlins USA in Henderson NC. A shaker table allows you to collect a
huge amount of data about your chassis in a short amount of time.
Various tests can be performed from simple increasing frequency and
amplitude oscillation tests, to exact duplication of tracks from around the
world. The control computer uses various data sources and controls the
impulse forces to each of the rigs 7 individually controllable hydraulic
actuators. Sensors mounted on the chassis monitor the vehicle's dynamics
and its reactions to the inputs.
Through careful analysis of the collected data, it is possible to tune the
suspension setup, finding out what works and what does not work. Up until
about 5 years ago, the only teams in the US that typically used these tests
were NASCAR, CART or IRL teams due to the cost. This information is
invaluable however when it comes to helping us provide a proper suspension
system for your 996.
