I'm sure there will be 3 or 4 from the WDWAHO bunch that enter. As you know that's all we normally race. What do you use for bodies? Re-painted and spoilered NASCAR bodies or Mead Bros. or both?

That's exactly right Phil. Some of us have been using Nascars and adding hood scoops. Also we've been allowing any full body car 1980 or newer models as long as their is a hood scoop and spoiler on the back. We have a few Vettes and Datsuns running here.
We haven't seen a need for wheelie bars in this class so there is no need to make them unless you want them for looks.
Anymore interest guys?

I'm sure this has been explained 1000 times but can someone explain the terms for the tree? such as Pro Tree .400
I know what the tree is just not how the staging works
Thanks, Tjet

I'm in for sure with a MM/PS. I might be able to get a couple more people to build for this class.

I'm sure this has been explained 1000 times but can someone explain the terms for the tree? such as Pro Tree .400 I know what the tree is just not how the staging works Thanks, Tjet Tjet, .400 tree means four tenths of a second elapses between the amber and green lights lighting up.....With a full or sportsman tree you would pre stage, then stage. Once both lanes are staged and the Amber lights start lighting up there would be 4/10 of a second between each amber light and 4/10 of a second between the 3rd amber and the Green light. With a Pro Tree all three amber lights come on at the same time (as opposed to coming on in series like a full or sportsman tree) and the green light comes on .400 (or four tenths of a second) after the amber lights come on. So you are trying to anticipate the green light coming on .400 after the amber and be as close to the .4 second interval as possible without leaving early and turning on the red. There are also .400 and .500 trees. A .500 tree means that there is 1/2 second elapsed time between the amber lights and green light coming on, rather than 4/10 of a second on the .400 tree. Hope that makes sense the way I explained it. ;D

Thanks for all that splainin. It Makes sense. So let me try this one...why have different timings?
Thanks again

I see enough interest for a MM/PS proxy race. I'm going to start a new thread for it else where with a entry list.

I think I have this right... The stronger a car leaves (i.e. quicker 60 foot time) the better the chance the driver's reactions to the green light will result in a red light. The car is so physically strong it can move the "roll out" distance too quickly. Therefore to cut down on red lights the sanctioning bodies went to the quicker .400 tree for the faster classes. (Nobody wants to watch racing very long when every race is settled by who red-lighted first... Might as well get rid of the cars and just reaction time race. ) The motorcycles are having problems with the same issue the last couple of years. They are so quick off the line it's hard for their riders to cut consistently quick lights without red-lighting too often. There has been suggestions of going to a .300 tree for them. The problem with going to the quicker tree for everything is that it messes up the slower reacting cars and their driver would need to leave on a yellow light higher up on the tree and it would really get screwy. (Did this help or just confuse/irritate? )

How does everybody feel about the current S/S rules? I think this is a great class that has brought some Nostalgic excitement to all that has participated.
Topics that I've heard some of the racers bring up. These are not my opinions.
- 16 Ohm minimum is too low
- Stronger, more modern motor magnets
- Allow bigger tires
I pretty much like the current rules as they are. One thing I'd like to see change is allowing bodies to be hogged out on the underside. There is no advantage that I see here since most of us are adding weight anyways. I have a few S/S bodies that have been hogged out that I'd like to use and that's my only reasoning behind this.
I'm on the fence with allowing bigger tires.
What do you guys think about S/S? Any changes that you would like to see? or should it be left alone?

I think perhaps the ohm limit was set too low. When NTRA set it , it was a generic number that was thought to be low enough to 'clear' all likely stock arms out there. It is apparent that the typical arm specs out higher. A low limit allows the one 'freak' arm to possibly dominate a class.
If we set a minimum weight, Hogged out bodies are a non issue, in my thinking.
Tires, I'm on the fence as well. Bigger tires will likely require wheel well alterations. Id like to see the 821's continue as standard.

ok guys i like the tire size the way it is and for ohm 's if we can get a arm that has the same ohm rating this is kool it should make things level but i am open to all things ntra

OK guys here's my 2 cents.
I think that the arm rule is fine. Dad's AMX had a Christmas tree arm that ohmed out at 17.6/17.6/17.5. He qualified #6. My torino was right at 16 ohms and my 64 ohmed out around 16.5. On my track the 64 is faster but at the nat's the torino was faster.
If you go with stronger magnets you are going to have to raise the voltage to make up for the cars slowing down. Jet has addressed this on his site. The three cars that we sent did not have the strongest magnets that we had in them. I tried the strongest mags/lowest ohm arm route and it was not my fastest setup.
As for the tires, I would like to see the rules opened up to include wider rear wheels and tires. The reason behind this is, If you want to run something other than the 821's you have to break up 2 sets of rrr wheels to get four narrow wheels. Also in SS NHRA, IHRA and the AHRA have always allowed wider tires on the rear than on the front.
Any weight that you save by grinding out the body will be replaced by ballast to keep the front end on the track. I don't see a big deal there.
These are just my thoughts and I will be happy to go with whatever you decide.
