Very Realistic Drag Racer (updated)

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 design a body and figure out how to do a timed track any help is appreciated.
