Feb 11 2012 7hr Lemons race at TWS
This is the sickest air brake you have ever seen. It has 2 pneumatic rams that raise a piece of plywood to act as an air brake. It is operated by a valve on the Ebrake. 2 air compressors maintain pressure in the system....and since apparently its too much load to try to run on the RX-7s electrical system there is just a generator bolted to the back that runs on its own fuel constantly while the car is on track.
The car also features a smoker grill with the Exhaust passing vertically through it on the back bumper so that you have slow roasted grub by the end of the race!
Chasing #35 240Z in #996 Spec Piñata at LeMons TWS 02/12/2012
This is the 2nd Spec Piñata appearance for LeMons. First was at ECR in
TWS was a blast, and I was fortunate enough to find a couple of similarly
fast cars both stints I drove. This video is of me chasing down the #35
240Z...which was fun because they were quite a bit faster on the straights.
LeMons Car Race at Charlotte Motor Speedway (Sept. 24, 2011)
I attended the 24 Hours of LeMons race at the Charlotte Motor Speedway on
Sept. 24, 2011, and had a lot of fun. I recorded hours and hours of video,
but boiled it down into this 5.5-minute video. I was there to watch my
brother (Joe Kovacs), who raced in the #71 car (a 1985 Mazda RX7), so there
is a bit of a focus on that car. However, I think it does a decent job of
giving the general flavor of the race.
I shot this with a Canon Vixia HF-S30 camcorder and used a GoPro HD Hero
for the on-car shots. I edited it with Corel Video Studio Pro x4 and did
the whole project in the AVCHD format.

2014 Porsche 911 Turbo - Aerodynamics Engineering video
For the first time at Porsche, active aerodynamics are being used in the
new 911 turbo models as a combination of
a multi-stage, adjustable front spoiler and rear wing. Look at the
breathtaking results in this video. More information on

Active aerodynamics improve efficiency and performance
Porsche developed an active aerodynamic system on the new 911 turbo models for the first time — Porsche active
aerodynamics (PAA). It consists of a sturdy, retracta- ble three-stage
front spoiler, whose segments can be pneumatically extended, and a
deployable rear wing with three adjustable wing positions. This makes it
possible to tune the aerodynamics of the 911 turbo to fulfil driver wishes for either optimal
effi- ciency (speed position) or top dynamic performance. In the
performance position, all segments of the front spoiler are fully extended,
and they generate considerable downforce at the front axle. Similarly, the
rear wing is extended to its maximum height with the greatest angle of
attack. This also generates more downforce at the rear axle. Dynamic
performance is improved to such an extent that lap times at the North Loop
of the Nürburgring are improved by up to two seconds due to this system
Mazda V8 Rx7 drifter - Episode 01 (THE PILOT)
This is my "pilot" to a new series I want to make this fall.
In this episode we meet the drifter Joachim Waagard with his V8 Mazda RX7
that he has built and already had one season drifting in. I hope to make
more episodes of Joachim and some other people for my series. Everything

VALTONEN MOTORSPORT Mazda RX 7 at Time Attack in 2010. The development with
the car went from power to aerodynamics and suspension. There is still to
do, but beside other joys, the unlimited class victory at Botniaring with a
class trackrecord and success at Gatebil Mantorp showed us that the way is
right. Thank you for watching
Jaguar C-X75 Electric-Turbine Concept
The C-X75 hints at an exciting evolution of Jaguar's design language while
paying homage to some of its most admired cars of years gone by. Advanced
design features such as a ground-breaking propulsion system and active
aerodynamics allow for an elegantly simple fuselage section that remains
stable at very high speeds.

Ferrari 458 Speciale - AERODYNAMICS
The 458 Speciale is the latest product of Ferrari's core philosophy of
extreme technological innovation and research which, in this instance, has
yielded powertrain, aerodynamics and vehicle dynamics advances that
transform the already exceptional 458 Italia into a car genuinely worthy of
the "Speciale" moniker. The result is a completely new, uncompromising,
streamlined sports car concept.
Many of the sophisticated solutions being applied for the very first time
to an in-range car in the 458 Speciale, including its advanced active
aerodynamics, will become a standard feature of all new Ferraris in the
Flanked in the Maranello marque's range by the multi-award-winning 458
Italia and 458 Spider, the new mid-rear-engined V8 berlinetta was designed
to Boost both performance and
driving emotion to unprecedented levels, yet simultaneously guarantee
smooth, effortless control in all kinds of situations.
Having lavished meticulous attention on the power unit that was named "Best
Performance Engine" at the International Engine of the Year Awards for two
consecutive years, Ferrari has now built its most powerful naturally
aspirated V8 ever (605 cv) with an extraordinary specific power output of
135 cv/l , the highest ever achieved by a road-going naturally aspirated
Thanks to an equally exceptional weight/power ratio of just 2.13 kg/cv, the
458 Speciale can sprint from 0 to 100 km/h in a mere 3.0" (0-200 km/h in
9.1") and also clocked a lap time of just 1'23"5 at the Fiorano Circuit.
Aerodynamic requirements guided the work of the Ferrari Styling Centre,
which led the project in cooperation with Pininfarina, to sculpt the car's
forms to ensure they were more performance-oriented than ever. The most
notable features in this sense are the front and rear movable aerodynamics
which balance downforce and cut drag, thus helping make the 458 Speciale
the most aerodynamically efficient range production car in Ferrari history
(E Index of 1.5)
The technology used in the vehicle dynamics subsystems which gives the
driver instant confidence and control at high speeds, natural power
oversteer management and precise response to commands are further advances
in an area in which Ferrari is already a well-established leader.
One of the most innovative content of the 458 Speciale is the Side Slip
angle Control system (SSC) which makes it easier to achieve car control on
the limit, thereby greatly improving driving emotions. Thanks to the
development of an accurate new algorithm SSC performs instant-to-instant
analysis of the car's side slip, comparing it with the target value and
then optimising both torque management (via integration with F1-Trac
traction control) and torque distribution between the two wheels (via
integration with the E-Diff electronic differential).
Part and parcel of the car's development included Michelin Pilot Sport Cup2
tyres which were specifically honed for it in an intensive collaboration
programme involving, amongst other factors, numerous track test and
simulator sessions. Conceived for the 458 Speciale, they Boost performance over a single lap in the dry
as well as improving performance consistency in subsequent laps. They also
allow the car to avail of maximum available grip in the wet.
The abovementioned technical content has improved the 458 Speciale's single
lap time and also delivers repeatability of that performance on subsequent
laps that is absolutely unprecedented for a car not designed exclusively
for track use. The result is that the 458 Speciale has the fastest response
time (0.060 s) and highest lateral acceleration (1.33 g) ever achieved by a
car in the Prancing Horse range.
The 458 Speciale will receive its public world debut at the Frankfurt
International Motor Show in September.
