Pro Radial
 
What is it –
 
 Heads up, pro tree drag racing. First to the finish wins!
 
Big Power on a small radial tyre (max size 315/60/15 Radial or 29.5x10.5 Pro Bracket Radial”)
 
Racing distance 200 meters (1/8th mile)
 
Production based cars (up to 3/4chassis)
 
Variety of power adders with 4, 6 & 8 cylinder engines
 
Weight breaks in place to keep parity between different power adders
 
Why -
 
Big power, Small tyres, in production based cars that people can relate to. Multiple power adders across the class allowing for some great racer rivalry (turbo vs nitrous) (blower vs Aspirated) etc which also brings extra crowd interaction.
 
Lots of new technology ( Fuel injection, extensive data logging etc)
 
 It is an extreme challenge to finesse massive amounts of power these cars make to the race track via a small and unforgiving tyre.
 
When the setup is correct, the tyres are so efficient that you will run faster than what was ever possible on a slick.
 
Where did it come from -
 
Drag radial racing started in the USA and then had massive growth in North Carolina where the original 28 vs 275 style races kicked the trend into high gear.
 
Now there are full calendars of radial races with multiple classes and formats in the US.
 
If you web search drag radial racing, there would probably be enough content to last a life time of viewing. There are races in the US that are offering $50,000 to win and there are lots of big time racers filling the pits to take some glory!
 
Some of the biggest US drag radial races are held by the NMCA, Duck X Productions (Lights Out & No Mercy Races @ SGMP), Outlaw Street Car Reunion Memphis, Yellowbullet Nationals Cecil County, Shakedown Norwalk, Fall Brawl Holly Springs, just to name a few.
 
Most if not every serious US drag strip has a Drag radial in their calendar.
The information & technology is being filtered to Australian racers fast and the increasing trend now is to ditch those old slicks and bolt on some drag radials and go fast.
