Coming up in July is the 2012 Summer National to be hosted by EagleRacing at Black Top Raceway. Featured at this race will be Top Fuel and Modern Funny Car Classes using the Type A and B chassis builds respectively. Preliminary rules are in the NTRA Race Guide and as stated some question and fine tuning will be needed to finalize the Type chassis builds. Much discussion took place in the thread 'What Would You Like to Race Next Year?' It was my understanding that several issues were agreed upon leaving mainly the weight to be determined. This link shows how I thought the rules were after some discussion in December. Not quite complete but the majority of the foundation is in place. www.ninjatekprojects.com/pdf/4g_2012_ClassRules.pdfTake a look at what is listed and think about some questions you may want to ask. This thread is currently locked and will not be open for posting until after 2012 Spring National is complete. This thread will not be unlocked until Wednesday May 8th @noon. |

Received multiple PMs about thread still being locked. I thought it a
little strange no one was posting questions. Sorry about that.
This time the thread is really unlocked and open for questions and comments.

1. Brush cups allowed in A type builds?
2. Silifoam custom or readily available?
3. When will weight be set?

To add to what Blue asked, rules state "Any brushes allowed". If brush cups are allowed, do we still have to run 'actual' brushes? If not, shouldn't the rule read "Any brush SETUP allowed"?  Once you start installing cups in the chassis, the space between the arm and the chassis/brushes starts to become limited, thus making brushes harder to install without modifying them, or using something else. NOT against that at all, as this is supposed to be the 'top of the line' class, but I agree we need better clarification on this. (for the record, I LIKE the idea of using brush cups..lol) And, at least in MY opinion, I think ANY tire, custom or 'factory' should be allowed on the "A" builds, as long as it meets the size maximums and minimums. Simply because it's hard to find many types of tires for this type of car (at least as of the current timeframe anyway). Ron (Bondo) |

1. Brush cups allowed in A type builds? The idea of brush cups is purposely left open and felt this would be an item of debate. During the prior discussion in coming to these preliminary rules, the impression I got was that the Top Fuel class should be an all out build. With that in mind I'm not opposed to the use of brush cups. My only hesitation is will this discourage newbies and those who are not familiar with brush cups. Also will the added cost (not that it is expensive) be a factor in lessening the turnout? This is one that I feel should be decided by members' opinion. 2. Silifoam custom or readily available? Again as an all out build I feel that any tires should be allowed with the only restriction being max diameter. Custom made included. 3. When will weight be set? Received a PM stating that AW stock TFs weight in at approx. 25.2 grams. I would like to hear some of the weights of some of those cars using custom cast bodies before a compromise can be reached. This is my feeling on the matter(s), other opinions invited. |

I like the idea of Top Fuel Dragsters being our fastest class with Modern Funny Car second and Pro Mod Door Slammers third. The rules are basicly in place to do this. I am in favor of no weight limit for Top Fuel. However you must still follow the rest of the rules ie rear wing, exposed engine etc. . Some will ask how can you lower weight, I say welcome to Top Fuel be creative ie lighten body, chassis. Those big rubber tires aren't light, use a lighter tire.
The AW Modern Funny Car weighs less than the Top Fuel. The build is basicly the same from A to B except no braids in build B which is the Funny Car. Ninja can correct if I am wrong, I think thats right. To make them a little slower we can turn down voltage. That is always an easy fix with adjustable power supplies.
To me bottom line is we need to keep this simple and inexpensive to start these classes. It is always more fun with more racers.

What is the differents? I have a modern funny car and goin to pick up a top fuel. Are the arms different in them? Because I thought they both where a 4 gear chassis. I thought I read that the top fuel had to have a 5 ohm or stock are and modern funny car was like 14 ohm or stock. I might have read wrong and dont mind being corrected at all.

Hmmm...Eagle brings up a point I had missed about no braids and shunts on the Funny Cars. Not too sure I like the idea of not allowing them. In my opinion, that takes these 'out' of a 'pro' class. Personally don't feel like they will run well enough to make it worth classing these as a 'pro' category now. In my opinion, that makes them nothing more than a 'nostalgia' funny car with a different armature and magnets. I personally think they would actually run slower than the Doorslammer cars, even with the poly mags.  (I may be wrong tho, as I haven't tested anything yet. I know, these things may seem 'small' but they are a HUGE difference when it comes to how the power from the track is transmitted to the car) Good thing I haven't really started my Funny Car(s) yet! I will, however 'go with the flow' should I decide to finish one. Ron (Bondo) |

Oh and Taz, yes, you read that wrong. BOTH classes can have a 5 ohm armature. The Nostalgia funny car class, which we (the NTRA) already had in place for the last few years, uses a 'stock' armature. Ron (Bondo) |

I am in favor of braids on the funny cars also. However I do not run shunts on either of my door slammers and I turned in some pretty good times. I think the funny car class will be faster than the door slammers one big reason is they weigh less. The other big reason is that 5 ohm mean green with polymer mags and higher voltage will really put out some nice rpm's.

Just slapped a Top Fuel together radio shack braids full of flux ,nick in the gear. Not the best car. At 22 volts still ran .751 with no brush cups, no shunts. Took the polymer magnets out replaced with stock AW ceramics, time .911 @ 22 volts.

Hey guys, Main question I had was about the weight. But after seeing brush cups and custom silly foams brought up. Wow, well I don't like the idea of adding weight so my vote on that goes for no min. weight. As for b/cups and custom sil/fo's, I like the idea of both. However neither of these is allowed in any other class we have. To allow them at this time seems to be giving those familiar with either or even both an advantage over those that are not familiar with cups or making their own silly foams. If these things are to be allowed, I think it should be for future races. To keep things fair for upcoming race with time frame as it is. I think parts should be available to all.
Had a question about classes where no balancing is allowed on arm. Can we apply a crazy glue to keep wire from unwinding. Recently got an arm with loose wires, runs and I thought this would help it last. Maybe ?
