Overhead Cam at 14K RPM
This video shows an operational cutaway of a BMW S1000RR — a 193HP
superbike — bumping against its 14,200RPM redline. A cam and valvetrain
at 118 cycles per second is an amazing sight (and sound)

Starting the 1909 Blitzen-Benz, UNEDITED, @ Pebble Beach Concours d'Elegance
The Blitzen-Benz was purpose built to do just one thing, to break speed
records (not racing), and it did repeatedly from 1909 through 1911.
(Edited version: http://www.youtube.com/watch?v=Ga2HtUHzUuw )
Its speed of 228.1km/h (141.73mph) on April 23rd, 1911, driven by Bob
Burman at Daytona Beach, stood as a record until 1919. Twice the speed of
the fastest airplane, (12 April, 1911, Alfred Leblanc @
69.442mph/111.801kph in a Blériot Blériot) and even shattering the record
speed of 210km/h set by a locomotive in 1903.
This record was not even officially broken in an airplane until 1920!
Of the six originally built, this is one of only two that exist today, and
is displayed at the Mercedes-Benz Museum in Stuttgart, Germany.
While the extended and nuanced effort required to start the Blitzen-Benz on
a cool coastal morning can try the patience of some viewers, its historical
significance and ground-breaking engineering brilliance still place it
amongst the greatest motor-vehicle achievements of all time, and the dozens
witnessing this effort felt it was one of the highlights of many great
moments at Pebble Beach Concours d'Elegance 2011.
Here's a great collection of vintage and modern images of the Blitzen-Benz
and other historic speed record contenders:
displacement 21500 cc / 1312.0 in³
bore 185 mm / 7.28 in
stroke 200 mm / 7.87 in
power 149.1 kw / 200 bhp @ 1600 rpm
specific output 9.3 bhp per litre
bhp/weight 137.93 bhp per tonne
50psi boost 1200+hp Nissan RB30 - Ethanol E98
Nissan RB30 SOHC 3L engine built and tuned by JPC making over 1200hp on
Ethanol fuel. The engine still retains a factory block and crank.
Improvements come from a custom JPC turbocharger, manifolding, roller rockers and cam
gear. Fuel is fed via ID2000cc injectors and an Autronic computer system.
This engine has previously run 8.79 at 160.25mph (with less power) in a
full weight (3250lb) Holden VL commodore through stock suspension,
Powerglide transmission, 9in rear end and 28x9in slicks.

Twin Turbo Ferrari Testarossa on Engine Dyno
Twin turbo Ferrari Testarossa on Engine
Dyno. The motor is a
4.9L flat 12 which has been upgraded with EFI via a Bigstuff3 PRO SEFI ECM
and twin Precision turboturbochargers. At this stage the motor is running
6psi Boost and has no internal
modifications. We ran it from 3500rpm to 7500rpm and it produced 650hp and
600lbs*ft of torque. Enjoy!
Also I just posted a new video on my channel showing a walk around of the
car with some of the new wheels and brakes mocked up on it. If you guys are
interested check it out there.
Subaru Impreza 10000 RPM engine
Takhle vypada subaru motor kteremu upadne ventil v 10000 otackach. - This
is Subaru engine, broken valve in 10000 RPM. This was not poorly tuned, EGT
and AFR was right, Problem was in material of one of the Cosworth valves,
there was air bubble in it and it broke apart. This was not one shot as you
think, this car was running few months before this and it is running again
fine after repair. But we changed manufacturer of vents :-)
