Very Realistic Drag Racer UPDATE V2

Based on my 4 Gear Transmission Car, I've created a full fledged realistic drag racer, (and the most realistic Principia car so far maybe?) it is manual transmission and you cannot change gears without using the clutch, a single rocket with just a little boost is only used in 4th Gear for some extra umph as I wanted the car to be motor driven mostly, I added some nice sounds for the car and lasers at front simulating engine spark, be careful, first Gear got some kick ;)

CONTROLS

RIGHT SLIDER = START CAR

W = GEAR UP
S = GEAR DOWN

AS WITH A REAL CAR LAYOUT

G = CLUTCH
F = BRAKE (TOGGLE)
H = ACCELERATE

C = in the display shows when clutch is depressed

Next to come a timed track and possibly a body for the car

UPDATE : 5th Gear fixed, 1st Gear not as aggressive, better the brakes, tweaked the engine sound much better now, all I need to do is figure out how to do a timed track any help is appreciated

UPDATE 2 :
Backfire popping removed to hear engine sounds better
5th gear removed
Clutch indicator removed
Better throttle added
RPM Gauge added
Boost gauge added (actually works in conjunction with boost when it comes in at high rpm)
Wheel spin in first gear added
Rear spoiler lifts in 4th gear
Shift light added
