found this surfing youtube today.  Its a sound file of the BRM V16 F1 car, a crazy ass F1 car from the 1950s that I had previously never heard of.  Far too insane to be remotely reliable during the 1950's, but sounds terrifying when its working.  And 5.7 BAR of boost = holy shit.
The Sound of BRM V16 (In-Cabin clip included)

From wikipedia:
    * Cylinders: V16
    * RPM: 12000
    * Displacement 1487.76 cc
    * Power 410.1 kW (549.9 bhp)
    * Dry sump 50 to 70 lbf/in³
    * 135 degree V16 alloy cylinder block and crankcase. Cast iron wet liners.
    * Bore 49.53 mm (1.95 in)
    * Stroke 48.26 mm (1.90 in)
    * Fuel system Rolls-Royce two-stage centrifugal supercharger with two 3 in (76 mm). SU carburettors. 5.7 bar maximum boost.
    * Fuel Petrol/alcohol fuel
    * Ignition Lucas coil, later four Lucas magnetos. One spark plug per cylinder
    * Valve gear 2 valves per cylinder @ 80 degrees with twin overhead camshafts per cylinder bank, via gear train from the centre of the crankshaft. Hairpin valve springs.
    * Inlet valves 1.25 in (32 mm)
    * Exhaust valves 1.09 in (28 mm)
    * Crankshaft Counterbalanced two piece with 8 plain bearings & 2 main roller bearings. (Later 10 plain bearings.)

In Raymond Mays' book, he claimed the following power curve with the 4.0:1 supercharger (5.7 ata):

    * 100 bhp (75 kW) @ 5,000 rpm
    * 175 bhp (130 kW) @ 6,000 rpm
    * 250 bhp (190 kW) @ 7,000 rpm
    * 335 bhp (250 kW) @ 8,000 rpm
    * 412 bhp (307 kW) @ 9,000 rpm
    * 525 bhp (391 kW) @ 10,000 rpm
    * 585 bhp (436 kW) @ 11,000 rpm
    * 600 bhp (450 kW) @ 12,000 rpm

They really need to take the rules off of racing again aside from something like displacement, so crazy shit like this and group B rally can happen again, and the resulting epicness/carnage can be recorded in stunning high definition.

That thing sounds wicked.

Some of the things developed from that era absolutely amaze me.

^truth.  saldy, most of the rules are to protect the idiots.

what was that one car with the fans powered by snowmobile engines that sucked it to the ground?

or the elf 6 wheeled f1 car.

Why haven't the British made a tv yet?


































-'Cause they can't figure out how to make them leak oil...

Jd will be irradiated by this statement.

yup. open the engine formula and limit the fuel supply. you can go as fast as you want, but you better use it wisely or you won't make it to the end.

That was definately one of the oddities of that sound clip - a decernable lift to shift. I won't be surprised when the rules make actual in-car driving illegal for most racing and instead use a UAV-style remote control system. Then they'll switch to computer drivers and RaceNet will take over the world.

I'm thinking a locost built a similar style...
