Kenny's ideas on drag racing a BMW turbo street/strip car.

I've assumed the following:

+ BMW turbo street/strip car (not racecar)
+ Drag Radials or Drag Slicks
+ Racing fuel (like C16 or VP109)
+ Manual transmission
+ Line locker
+ Racing clutch
+ Boost controller

Setup At The Strip - Tyre Pressures
Set the pressure in your front runners to the maximum allowable (say 55 psi). Then forget them.

Cars over 3000 lbs are considered a heavy car by drag racing standards. There are special slick compounds for cars over 3000 lbs (most of us).

I'd recommend starting with 18 psi and varying to see what gets you the best short time.

Remember small slicks need more air in them, especially with high power sedans. Don't listen to knuckle draggers who argue for 6psi. That's fine in their 2000 lb dragster with 33"x17" slicks at 300 MPH in the top end!


The Burnout - How Long?
Drag Radials (eg Mickey Thompson ET Street) require two hard burnouts to get up to heat. After tha a quick burnout before each pass.

Drag Slicks require one hard burnout at the start of the night, followed by a light burnout each time.

For a hard burnout wait until you can see the rubber hazing and then button off.


The Burnout - How To Do One?
Select 3rd gear with your rubber in the waterbox. Now pump up your brakes and activate your line locker (if you have a brake pressure guage you're aiming for 2000 psi).

If you are running a twostep activate it now in burnout mode.

Fully press the gas pedal down and wait until you hit the two step, then step off the clutch while keeping the line locker activated.

When you see the rubber hazing, deactivate the line locker and allow the RPMs to drop, then button off.

Stage immediately while the rubber is sticky.


How To Bump On To Full Stage
Creep into Pre-Stage. Pump up your brakes to about 300-400 psi on the brake pressure gauge. Activate your line locker.

If you are running a two step activate it now in launch mode. If you're running anti-lag activate it now.

With the line locker on, dial up some RPMs and slip the clutch out a little so the car is pulling against the brakes. This way you can very precisely bump in to full stage.

Once in full stage clutch in and floor the gas pedal. You are now bouncing off your twostep limit and antilag is popping away nicely.

The Launch
When you see the last amber light drop the line locker and step off the clutch in one motion. Start shifting fast!

At the Stripe
Stay into it for one-one-thousand-two-one-thousand after you think you've crossed the stripe. That's to make sure you actually have crossed the finish line before you button off.

Stay into the gas as you trip your parachute and wait until it's deployed, then button off and slip your tranimission into neutral. Let the 'chute kill most of your speed and then ease on the brakes slowly and gently.

If You Break
If something lets go then it's usually at the start line. Immediately drive off the race line towards the sidewall and stop as quickly as possible. That reduces the cleanup time for the track officials if you're dropping any fluids onto the race surface. They will like you a lot more if you remember to do this.

If the Car Gets Loose
When deciding to stay in it, click up a gear or button off ... button off!
