2013 B MOD rules

Hello, I recently moved out here from the KC area and have been watching this forum since I moved out here. I recently started building a B-Mod. I raced under the old IMCA days back home. I am curious to get everyones opinion on this issue. It appears that tracks out here like to have the "same class" with very different rules. We had the same issue back home and the sole purpose was to lock you into only being legal at thier track thus they new that thier average weekly car count would be. Is Allied the only association that runs more then one track? Why is it so hard for Promoters to work together? Seems if a few promoters could get together and run a "Dual Points" series that everyone would benefit..
 
This is a 2 brrl class keep it that way. They should never allow the GM crate motor to run a 4 brrl. It doesn't have that much horsepower on a 2brrl to bad build something else. Cost???? Please whoever has the money will spend it however they can to be competitive. Keep the rules 360 or less on 3 link. We don't need "cheated" up crate motors running on 4 brrl's.
 
Very glad this thread has stayed "clean".
I believe promoters are working together more than everyone thinks.
 
I just hope they get it hammered out cause i like watching the b mods...i hope your right adam about them working together !!!

I tried.

On that note, what I would REALLY like is to use Allied Sportsman engine rules. Choke the engine down with the carb and intake.

How about body rules guys? Do we want rules that will set up apart from the UMP Modifieds(for example short sail panels)or use the same rules? I personally don't care as long as I can tuck the tires in the rear lol.

Let's get our heads together here and hopefully keep this class from spiralling out of control like the A mods have.

I think Allied is the only track that promotes multiple tracks like they do. I know SARA used to, but they are gone now? Not sure about Fayette County and Highland though.

It would be awesome to have a "blanket" association though, similar to UMP. Chasing championships is a lot of fun.

I was hoping to build a car that I could jump across sanctioning body's, but sadly the rules from Highland to USRA to IMCA are just too far apart to attempt it.

My opinion on the body rule....go old style. Make them boxy and not so flashy. I like the carb rule.....3 link and heck......id even say leaf springs would be in order and thats not hard to set up on any car. Good thread..........lots of good info here.
 
I agree with the option to go leaf spring to add variety.

But I'm totally against old style bodies. The current style modified is absolutely gorgeous. No reason IMO to get away from it.
 
this class seems to me JUST like the sportsman class, a few places running them but everybody has different rules. Highland would have benefitted greatly by allowing sportsman cars to run with their noses this year but were too hard headed, i bet they would have averaged at least 3 or 4 more cars a night. i dont have a problem with the 355 rule, but a compression rule is too hard to police. what is the difference between a guy with 64 cc heads and 12.5:1 pistons vs a guy with flat tops and 49cc heads? NOT MUCH. they need to allow guys to groove the emods, that would save a lot of money on tires. I think rather than creating a whole new class, the promoters should have done a few things to make the modified class cheaper
 
I agree with the sportsman class comment Jimmy. Tracks need to realize in order for this class to thrive, we need a set of rules that will allow us to race more than one place!

On that note; here is Allied's sports engine rules. And Jimmy, compression rules are not hard to police, you just have to have tech man that CARES!

i like the 360 cubic inch motors,, 3 link rear end , 2 barrel carbs. just hope they get it figured out so i know what i'm going o do.
 
T.C., once again I have to agree with you. If you are gonna have Bert/Brinn trans., 50 lbs. would be ok as long as it is in front. But, on the other hand, I think if you want to keep this a true economical class then let's just stay with truck trans. and stock clutch with aluminum flywheel. To heck with the triple disc or tranny that costs a fortune. I also agree with Jimmy. The "A" mods have gotten out of hand, and it started by putting after market parts on them. An aluminum head here, a Bert trans. there and the next thing you know everyone is complaining that the tracks don't pay enough to pay for the out of hand cost of their cars. Racers can be their own worst enemy. I just hope that this time we use better judgment when it comes to cost. It would take some of the pressure off both car and track owners. Again, jmo. BTW, it is refreshing to see a post where everyones opinion is respected even if it is not agreed with, Dialogue is a good thing.

Yes, I know it's hard, but not impossble. I personally think it's harder for me to come up with 12 to 15 hundred dollars for a Bert than it is to find a truck tranny. I know that some people will say that a guy doesn't have to run a Bert if it is allowed, but that does not make for a level economical
playing field.

First of all, I hate the normal reference of Bmod being "beginner". Would really wish it was called Limited Mod. Im not a beginner and have no intentions of moving up to A mod simply because of the money involved, I think its just crazy to spend another 20k to be competitive and just race locally.

I really wish the rules that Doe Run, Farmington, Callaway (minus the "any carb with 2 holes rule") and MMP use would be considered. I dont know the car counts at Farminton or Doe Run, but Callaway and MMP average 18 or better every week, Callaway had 5 different winners and MMP had 6 (3 were 3 link cars). Callaway was completely dominated by a leaf spring car for the last 5 years untill this year simply because he didnt race. Plus theres no more than 1 or 2 cars that run both tracks. Also,, if a good USRA b mod shows up, you better have your **** together because its not a fluke if they give you a spanking.

As crazy as you might think our rules are, there very simple and keep everyone competitive.
 
Agree with Mike on that one ^. Fulton has pretty open rules and I don't remember the last time they got under 18 bmods. Not saying that anything goes should be the way to go but I think the rules MMP and LOS had were pretty even for any option (open, sportmod, USRA). I think allowing berts is a good deal with weight added if enforced. By the time you buy all the bells and whistles to run a 3 speed with clutch/throw out/etc, you may as well buy a Bert, let's get real a quality tranny is gonna last a lot longer in the end and save money! Also the Bert/Brinn's ate A LOT safer. jmo.
 
if you want to run allied legal motor run it under highland b town rules it meets criteria class has to keep 360 cubic inch limit and trans think ur best bet is bert or brinn 3 speeds getting harder to come by and there are other alternatives we have racegators same as brinn call me at shop will be suprised at cost savings of a new one
 
Highland Speedway will have a SportMod meeting within 2 weeks of the season ending. We will announce the date as soon as possible. Please be prepared to bring your comments and concerns to that meeting. Thanks!
