Burnout
Without a Line-lock--The Procedure
Drag
radial tires must be heated by a burnout or else they'll provide
traction no better than a stock tire. I've found through
experimentation that stock tires too benefit from some heat. This
only matters once driving is dialed-in. But heating the stock tires
by a burnout will improve traction on launch and shifts. Here is
the procedure.
Step
1
Put car in Competitive Driving mode (C5 Corvette) or TC-Off (C6
Corvette). Other platforms should use the setting that disables
traction-control but retains stability control.
Step
2
Drive
around the water. Keep the front tires dry, Otherwise, your heated
rears will drive through the water trail left by wet fronts on the
way to the line.
Step
3
Back
into the damp area, not the wet area. Back up enough to get 3/4 or
more of the tire tread damp. Don't spin the tires in the water. You
just want to get most of the tread with a sheen of water.
Step
4
Roll
forward to the leading edge of the damp area. Start the burnout
there. Do NOT roll so far as to put the rear wheels onto the heavy
sticky rubber/VHT prepped area. The car should start and finish the
burnout with no more that a foot or so of forward movement.
Step 5
Put
the tranny in 2d gear. This will enable the tires to heat faster,
because they’ll spin at a higher indicated mph. Since the tires are
damp, they spin quite easily in 2d. Some owners prefer first gear.
And that's OK.
Step
6
Rev
the motor to 3500 and pop the clutch. Immediately lightly apply the
brakes with your left foot. The brakes help keep the rear-end from
walking sideways.
Step
7
Bring
the rpm to about 5000 and hold it there until the drag radials
smoke strongly and start to drag down the rpm. At that point, back
out of the throttle and release the brakes. You'll roar forward.
The tires are heated. For stock tires, spin them only to first
smoke. It is helpful to adjust the driver’s outside mirror to view
the left rear wheel/smoke.
Warning:
if you botch the burn-out, don't retry it with dry tires. Doing
that will likely glaze the clutch...or…break an axle. Instead,
start again at
Step 3,
by rewetting the rear tires.
Practice will help get the synchronization of the foot
movements.
You can practice in a level asphalt parking lot with water from a
couple gallon jugs.Draw a couple lines with chalk to help establish
an alignment guide. Pour out three or four gallons of water
generally at the wheel points. Voila. You’ve got a pseudo
water-box. An observer/spotter is a plus.
Don’t worry about brake wear. Five seconds on the brakes is like
braking 60-10. You do that every time you drive the
car.
