Their are two major components that comprise reaction time: the driver’s reaction to the tree and the vehicle’s reaction to the driver. The latter is somewhat easily adjusted: If the vehicle is leaving too quickly or too slowly, the driver can leave at a different rpm, change the pressure of the slicks or change the travel of the front suspension.
But in the case of the driver’s reaction time, what can be done if he or she is just inherently slow? Remember, both components of reaction time must equal .500 in order to equal a .000 light (assuming a 5/10ths tree).
In the first “Take Action” column for Drag Racer magazine, I detailed how to use a practice tree to determine your own reaction time. In the second “Take Action” column I discussed vehicle reaction.
If either of these is sufficiently slow enough and you’re racing in a bracket class where you are likely to come up against much faster and therefore quicker-reacting vehicles, then deep staging should be considered. I’m not advocating deep over shallow, but there are situations in ET bracket racing where staging deep should be considered.
For example, if you and your car are no better than .080-.090 when staged shallow on a pro tree, then the only way you’ll be able to cut a good light with that vehicle on a full tree when staged shallow will be to follow the tree down and anticipate when to leave. This is not typically a consistent way to race. In addition to cutting a light with a slow-reacting vehicle/driver combination, there are some other benefits to staging deep.
First, you’ll be able to stage at a much lower rpm (typically somewhere between 1,800–2,400), so you’ll be putting a lot less stress on your parts and heat into the motor, converter and transmission. As a result, parts breakage is reduced. Tire spin becomes much less of an issue, again because of the low launch rpm, so consistency can improve. What should you do if your combination warrants experimenting with deep staging?
First, check with your track and/or division to find out their policy on deep staging. Can it be written on the car? In NHRA Division 1, for example, it cannot. Also familiarize yourself with the track’s tree settings. Do they use Autostart? What are the timeouts? I’ll be discussing Autostart more in-depth in a future column.
Lastly, be considerate. If you’re going deep, get in first; don’t hang your opponent out by taking a long time to knock out the top light. Deep staging is a privilege, not a right. The whole purpose of ET bracket racing is to give vehicles of different performance levels an equal chance at success.
A vehicle’s performance level can determine that vehicle’s reaction, and in order for all of the vehicles in a class that has a large ET spread to have an equal chance at success, some of the vehicles will need to be deep staged. A 17.99 vehicle will have an inherent reaction-time disadvantage to a 9.00 vehicle if both are staged shallow. Allowing bracket racers to stage shallow or deep as they deem necessary ensures a more equal chance at success no matter the vehicle and can help grow our sport by attracting new participants who feel they might have a chance at winning regardless of the ET performance of their particular vehicle or the depth of their pockets.
We should be doing everything we can to attract and retain new participants and not lose them to frustration over being shut-out at a chance to win based solely on their type of vehicle or the limitations of their budget. If deep staging helps them cut a competitive light and possibly go some rounds, perhaps they’ll come back next week and keep the momentum going.
