BRM - full track.mp3 3.46 MB
The is one is the full recording of the BRM running around the track, but
with *slightly* less audio 'detail' to keep the size down. It has the car
being push started (they have no on-board starter) then doing two laps
before returning to the pits. The same thing is then played from a
microphone inside the cockpit. Note that while the car is running around the
track, as soon as it starts to warm up, the engine begins to miss,
unfortunately ... Here's a quote from the driver - "Once the needle reaches
six, it is as if you have just pulled away from the start like any other
car, because six is where the BRM begins to work,. From there until
12,000rpm, the power almost doubles with every 2,000 revs. Or at least it
did. I could get to about nine by gently coaxing and tickling the
accelerator. Then the engine would cut dead as if someone had switched it
off. Pull my foot gently from the pedal and the 16 cylinders come back to
life one by two, by four by twelve. Accelerate again and they cut. Too much
pedal too soon and they cut. Various theories abounded. Perhaps the methanol
from the big carburetor that feeds the supercharger, designed and made by
Rolls-Royce, was freezing somehwere between the blower and engine. Maybe the
vegetable oil that burns with that unique, savoury tang was oiling the
plugs. Maybe one or two or three of the four magnetos were shorting inside
themselves once the sparks grew too frequent with rising revs. Maybe
..." And later this - "We would try just one last time. The engineers
removed and soaked the rows of spark plugs in petrol to remove traces of
oil, replaced them and gave me an immediate push start. I was to drive off
with the engine under load in the hope that this would make the fires burn
hotter and keep the plugs clean. It worked for just half a lap before the
stalls started again, but it was enough to see how fast this car could be.
So powerful was the engine even in this hesitant half-throttled state that
the rear tyres would light up every time the engine passed 6,000, whatever
the gear. Every time they smoked and spun, the rear end would dip on those
oleo struts and the car would snake and slither. The engine is vastly,
ludicrously powerful for a pair of tyres just ten inches wide."

This is the car doing a full-race start. I'm amazed at how quickly the engine revs pick up.
