Welcome to  AmericanDRAGCAR        

What is AmericanDRAGCAR ?

To answer that question, consider this question;

What is the definition of drag racing?

Drag Racing, v. 1. a competition of acceleration between multiple vehicles on a straight course with the objective being to cross the finish line first.

There is no "breakout" in drag racing.

So, to answer the first question;

"What is AmericanDRAGCAR ?"

AmericanDRAGCAR  is drag racing!

AmericanDRAGCAR  is the drag racing venue which has solved the age old dilemma of how to create an equal playing field non-breakout drag racing competition where nobody gains any substantial advantages over anybody else simply by having a larger monetary racing budget to draw from.

AmericanDRAGCAR  doesn't put down traditional bracket racing, but if you have ever wanted just to race to the finish line without being sent home because you actually got to the finish line first, then AmericanDRAGCAR  is for you!

AmericanDRAGCAR  incorporates a variety of formats into it's venue which all focus on providing racers and spectators with an all-out drag racing program which remains fair for all participants involved and more exciting and easily understood to watch.

bullet

DRAGCAR 's DragStar/DragCar  class racing formats use an exclusive classification and indexing formula to provide all racers the ability to perform in a comp eliminator styled competition where going faster is better and being the fastest is the ultimate goal.

bullet

DRAGCAR 's DragSport  "run what ya brung" or "ultimate bracket racing" format provides everybody with the ability to compete in an all-out drag racing program on virtually any racing budget. If you have a vehicle safe and legal to run down the track, you can compete in DragSport Eliminator.

bullet

DRAGCAR 's Blackout  formats provide for both "outlaw" spec free heads-up style eliminators as well as a "no-nonsense" introductory eliminator platform for the novice racer not yet familiar with all of the meanings of the numbers

Unfortunately, creating a drag racing format with no breakout which remains fair for all requires an intricate rules outline that reads a bit difficult and this is the only drawback to newcomers to DRAGCAR  but once it's understood, it's easy to see how it works to provide for some outstanding no-breakout drag racing that everybody can enjoy.

 NOW, Let's Go DRAG RACING!   

DragStar/DragCar/DragBar Formulated Indexes

The DRAGCAR  indexing formula is a complex equation which takes into account a number of basic engine specifications to establish it's power producing capabilities. This then becomes factored into the weight of the vehicle and converted into an on-track performance index standard.

        The base indexing factors are:

1: Total Vehicle Weight (with the driver)
2: Total Cubic Inch Engine Displacement (cc's and liters will be converted to c.i.)
3: Actual Intake Valve Head Diameter
4: Gross Intake Valve Lift (@ zero valve lash)
5: Carburetor/Injection Throttle Bore Size and Quantity (2 barrel, 4 barrel, etc.)
6: Method of Induction (Naturally Aspirated, Super/Turbocharged, N2O Injected)
7: Type of Fuel being Used (Gasoline/Methanol)

Due to the complexity of this formula, having a number of "if" equations, racers wishing to know their indexes before entering into a race may at any time submit an index request form directly from this website and have their index and minimum weights Emailed back to them. There is no limit to the number of index requests permitted.

FAQ's about  AmericanDRAGCAR        

 
bulletHow does DRAGCAR  keep those with the most money from dominating the fields?
    By incorporating the engine's intake valve size into the index formulation,
DRAGCAR creates equally attainable performance standards for a wide range of racing budgets.
bulletWhat if I don't run as far under index as most others in my field?
  
Unlike most other class racing programs,
DRAGCAR 's formula allows for much more affordable methods of attaining competitive performances such as camshaft swaps, carburetor swaps, varying intake valve sizes, and varying engine displacements. This is in contrast to having no other option than to increase the cylinder head's flow capabilities to attain favorable under index performances.
bulletWhy does my car get indexed so much quicker than what it really runs?
    In some cases, racers find their indexes to be far from what they are capable of running. This is due to the formula being written around the premise that it is a race program for race built engines. In some cases "mild" short duration "street" camshafts do not utilize the maximum potential of the intake valve being used, and in other cases the intake valve being used is far bigger than what the cylinder head can efficiently utilize, therefore these types of combinations commonly cannot attain the performance levels indicated by the formulated index standard.
bulletHow can I compete when running with a "mild" or "overkill" combination that's not able to run under the index?
   
DragSport Eliminator  is the "catch all" "no breakout bracket racing" category for those who do not run under index nor care to engage in modifying their engine combinations in order to do so but still wish to compete in a real drag racing venue where only the racer's ability to reach the finish line first decides the winners.
bulletIs there any point where running too fast will disqualify me?
    Not in the formulated index categories.
DRAGCAR  maintains a true drag racing program where the first one to the finish line always wins.  However, in the adjusted index categories, there are generous "Sandbagging" disqualification rules put into place simply to keep racers racing while keeping the games to an absolute minimum.
bulletHow can I trust that cars running faster than mine are not being falsely claimed?
    Competitors will be subject to periodic inspections to ensure racer integrity both by
DRAGCAR  initiated teardowns as well as through racer initiated protest teardowns.
bulletWhy can't I see the formula so that I can figure my own index?
   
DRAGCAR 's indexing formula is quite complex with many variables instilled into it which change infinitely according to the vehicle specifics being entered.  This would be quite confusing and possibly discouraging to some who may feel it is too complicated to try to decipher.
bulletHow can I build a competitive engine combination without having access to the indexing formula?
    It's really much easier to build a competitive engine being indexed with this formula without seeing the actual formula than one might think. Ideally, one would merely build the engine around the intake port by first fitting the head with a valve that is only capable of flowing what the port is flowing.  To get a close estimate to what a particular valve size may be able to flow, use the following equation;

Valve Dia.2 x .7854 x 91.5

Example: for a 2.020" valve;
2.020 x 2.020 x 91.5 = 293.23

Then divide the intake valve diameter by three to determine the optimum gross valve lift, and this is an ideal starting point.

Example: if running a 2.020" valve:
2.020 / 3 = .673"

Using these formulas as a guide, it is likely that a good valve size for a head flowing in the 280-295cfm range would be 2.020" and a good choice for a camshaft would be one which opens the valve in the .650"-.700" range with a very aggressive and well timed profile.

We will work to build an instant index form on the website so that racers may play around with a variety of specs to get a good idea of what type of combination they would like to build for a DRAGCAR  class, but as of this time, racers and engine builders are more than welcome to inquire with any number of engine combinations to be indexed. All will be answered!

Again the key in DRAGCAR  is in having a combination that works most efficiently with the cylinder heads that are being used.
