Pinewood Pro Products - Track Tested for Speed
We ran hundreds of races using controlled experiments to get statistically valid results.
Experiments were controlled by replacing a single item on the same car and then running that car down the same lane 10 to 12 times on the same day to minimize variability. We used a spacer gauge to gap the wheels to eliminate wheel spacing variations. We did NOT use graphite because uneven application of graphite would add variation.
The resulting data was cleansed, averaged and charted so you can see the exact speed increase you can expect over stock components.
While our experiments were highly controlled, please read our notes about Things Beyond Your Control to see why Pinewood Derby will always have variability, and unpredictability, which is the very thing that has made this event fun for over 50 years!
Tests were performed on a 6-lane aluminum Best Track with a Fast Track electronic timer.
We hope you find this data helpful in selecting products for your race.

Track Tests on our Pinewood Derby Wheels
Ultra Lite Awana Speed Wheels
Will increase your speed by an average of .297 seconds over stock wheels.
Tests were performed with our Nickle Plated Speed Axles. We did not use graphite for our tests because we did not want to introduce variability where too much, or too little, graphite was added to an axle.
Awana Ultra Lite Speed wheels are precision lathed on the outside tread, inside tread, rim, hub and inside of the wheel to lighten it, giving you a fast start and perfect concentricity as it flys down the track.
NOTE: These wheels are not for Cub Scouts BSA races.

Speed Test notes:
This test was performed using our PRO Super Speed axles. We ran the same car 10 times with no graphite. Then we removed the axles, added our PRO Graphite, then re-inserted the same axle and wheel into the same position on the same car and ran it down the same lane another 10 times.
How this helps you:
Things beyond your control
We did an interesting experiment...we ran the same car down the same lane over and over with NO CHANGES. The speed varied by as much as .105 seconds using a rail rider car (26 runs) and .271 seconds for a non-rail rider car (19 runs).
Why so much variation???
Basically, there are always variations...consider the following:
- How the car was placed at starting gate. This will change with each run. If the car was skewed, it will slow down when the wheels hit the rails (yes, even for rail rider cars!)
- Lane condition, also known as a "slow lane" due to lane construction or small amounts debris
- Tracks have joints where sections meet. Joints don't match perfectly, making the car jump at the joints.
- Something in the lane (bugs, dust, broken car pieces, wood chips, etc.)
- Starting pin drops, then pops back up on metal tracks, hitting bottom of car and popping it up (loses ~.04 sec)
- "Sticky" starting pin - some are covered with plastic
- Car dropped or man-handled, between races causing wheels to misalign
- Car jumps a lane. This causes wheels to misalign and can scratch and damage wheels
- Cars crashing at finish line (I've seen this many times) can cause wheels to misalign and/or scratch wheels
- Car jumps off track entirely - causes wheels to misalign and/or scratches wheels. Can also cause dents and ruts in the wheels
- Powdered graphite blows off with each run. Statistical sampling showed an average speed loss of .019 seconds per run.
- Wheels loosen and gap widens, or the "car handler " holds car by the wheels, pushes wheels in and they bind together
- Car wheels misaligned (impossible to get car going straight AND staying straight), causing car to bang off the rails or drag on the rails
- Decorative part or small weight pieces fall off car, changing the weight and balance of the car
Bottom Line is...pinewood derby racing is unpredictable, and that is why it has been so much fun for over 50 years!
So, Pick your best products, Do Your Best, and enjoy the ride!
Our products and track testing will help you do your best...we leave the fun part to you.

Tips & Hints
Many of the BSA "nails" that come in your kit are crooked. Chuck each axle in your drill and spin them. If the axle looks blurry as it spins, that axle is crooked. Replace crooked axles or consider getting an Axle Press Tool to straighten crooked axles.

When painting with children, it is better to use a paint brush rather than spray paint because spray paint can cause vapors. If the child is spray painting, be sure to use a breathing mask and be in an open area.

We ran our 3 cars at a local pack meet, and what a great time my kids had. Both of my two boys prepared their cars with your tooling. My boys were given first and second place.

This was our very first time building a Pine Derby car for Awana Club. We won first place in our age class and 3rd place over all the age classes up to high school. Thanks, Pinewood Pro!
This is our second order with Pinewood Pro and everything from the website to the delivery to the product has been excellent. As a Dad experiencing his first Cub Scout Pinewood Pro is a great resource to make sure I don't screw up! Thanks,

Thanks for all your help to get first place in tiger cub class.
One of my girls won the "girls fav" car which was picked by all the girl scouts as their fav. Thanks
This was my 7 year old son's first Pinewood Derby and I would have paid 100 times the price just to see the expression on his face when he took first! Your information was invaluable!
