The smell of un-burned gasoline was wafting in the air, as she checked the tire pressure for the last time. It rose significant in the fifteen minutes
before she stopped, as the tires warmed up and pressure had to be adjusted down. She then could feel the hot tarmac radiating heat onto her hand as
she slotted the torque wrench, starting slow but increasing the force on the lever. A soft click protruding the night, not much louder than the
titanium pipes crackling sound of cooling down, gave her more confidence, each time she heard it.
After all the other external checks were done, she sat inside but didn't strap into the belts yet, as she knew better. Three short and fast beeps
told her that just now, a myriad of electrons were flowing through the ECU's processors, finding there way to do their magic. Line after line the
computer went to show it's progress on the little LCD screen mounted in the foot department of the passenger seat. She wouldn't have time to look at
it soon enough, but for now, each line was important.
"ZÜNDUNG" flashed up and she felt the adrenaline rushing into her gut, intensifying all senses. She closes her eyes and tries to keep track of the
revolutions the engine went through, as she turns the ignition key, before it comes alive. It's always the 6th when it's pre-warmed.
Numbers dancing on the screen now, giving an idea about the engines condition. RPM swaying around 1180, oil pressure above 4 bar and would nearly
double towards the end of the usable RPM band, located at just below 10 000 RPM. Different other sensors provide temperatures, air fuel ratio, angular
velocities and angular tilt, injector load, injector cycle and cylinder filling grade. Too much, to make sense off, if you are not an ECU, just enough
to get it responsive and angry.
Gentle pressure on the throttle reveals a clean but yet shy increase in RPM, boost pressure gauge approaching atmospheric pressure, indicated by the 0
on the gauge. A popping sound from the back, as the engine falls back to idle. Igniting still un-burned fuel vapors at the hot exhaust tip when it
tangles with the oxygen enriched cold air. A press of a button and a whirling sound, she watched the intake temperature dropping about 8 degree, as
tiny jet outlets in front of the inter-cooler spray a mist onto the fine girdles, cooling the air flowing through it dramatically after it has been
compressed by the heavy modified turbocharger. RPM increasing slightly. Perfect.
Strapped into the seat-belt, a last deep breath as she put her foot into the two stage clutch and tugged the sequential shifter, *clonk*, into 1st.
The warm and sticky 18"/295 semi slick on the rear would bite hard enough to either snap the shaft or stall the engine, if the clutch and throttle
were to be used crudely. On her way up the ramp, she listens to the sounds the car makes. Now the exhaust gasses are pressing hard enough rough the
equalized downpipe, to spin up the turbo. Fitted with a smaller exhaust housing, a modified compressor wheel, it will produce the hate needed for
squeezing out every newton meter possible out of every injection cycle.
As the ramp straightens and no lights are visible front or back, she floors the trottle in 1st, doing around 70km/h. A short lag, hell breaks loose as
the straight cut gears begin to whine louder. Infernal roar as the seat seems to try to swallow her body, the belts loosen up a bit but she can't
move anyways. The two fuel pumps fighting the G-forces to deliver fuel to the front. As the RPM runs towards 8000, more a feeling than a fixed number,
it's time to move the hand away from the steering wheel, shifting into 2nd as the engine approaches around 9600 rpm. Above, the rev-limiter would
step in, protecting the engine's valves from floating and melting away as the spring would not be physically be able to close the valves, fast
enough. As the electronic signals from the camshafts angular sensor begin to saturate with noise, the ECU is on a blind fly vigorously injecting the
108 octane race fuel spiced up with additives.
To deliver the boost topping out at 2.6 times the atmospheric level, into the next gear without lag, she must not use the clutch but instead lift the
throttle a tiny bit. The parts in the transmission unload a split second before the dogged gears slide together and engage violent. Time seems to stop
for a moment, as the car jumps forward with spinning wheels, stamping into the tarmac left and right front and back, like bundle of TNT was going off
behind the the car. All the way through 2nd the wheels fight for traction while she fights to keep the car aligned, approaching 160 km/h, shifting
into 3rd with another flat shift.
As the wheels gain traction from the down force directed from the rear spoiler and hood, the acceleration rate seems to skyrocket, making it hard to
breath, shaking up her vision. The air screaming as it's split by the spoiler, forcing it apart, sucking it down, like an inverted air plane wing.
The speedometer relentlessly approaches 220km/h, hello 4th gear! The acceleration becomes bearable. She's still alone on the road as every red light
in front would become a safety issue now. She changes lanes to the left, just to be sure. This takes a couple hundred feet and as the car stabilizes,
5th gear is engaged, passing 270km/h. Flat shift done and right index finger on the switch mounted at the steering wheel's right truss. The water
ejectors saturate the inter coolers fine channels and cool down the aluminium and thus the air flowing through, before the engine ingests it, fighting
the air resistance the car now has to overcome. It's time for the magic 6th gear when she hit's 300km/h. Fuel injector flow rate is now maxed out,
delivering what is physically possible to the hungry chambers of the inline 6 RB30DET, water ejectors still half a tank left, indicated by a yellow
blurry light below the boost gauge turning on.
"You're going to make it this time" she think's, as she feels the dopamine rushing into her system. 310...320...330...never been faster...340!!!
The car's suspension begins to oscillate a bit but letting of the throttle in panic would be unwise now. She kept her willpower and a quick peak on
the GPS screen told her she passed 350 km/h, covering the distance of more than a football field a second. The car would keep on going but the tires
would not for much longer.
Slowly lifting the throttle, a tear of joy runs down her cheek, mixing with the feeling of accomplishment. There is yellow flickering reflecting from
the downside of the rear spoiler visible in the rear mirror, indicating the rich air fuel mix igniting at the back of the car. A safety measure to
keep the cylinder walls cooled and lubricated, not a show factor indeed.
The fuel would not last towards home, so she takes the last chance to exit the autobahn, cool down the engine, get some fuel, a snickers. She earned
it. Later, the statistics would indicate the fastest run this chassis has ever seen and the fastest speed ever traveled on tires. +1g angular
acceleration.
Bubbly tires that engulfed stones into it already. On her way back, she stops at the ramp to look at the four thick black lines leading all the way up
to the autobahn. Next summer, we crack the 3.5 second barrier 60-125mph, she thinks. Second gear to third gear needs a fuel map adjustment. Less is
more in this case, she thinks.
But not now, now we rest.
