2010 Rule Proposals

 

Below are the rule proposals to be considered at the WMRA meeting on February 2 at the Hawks Prairie Restaurant.  Everyone is welcome to propose rules. Rule proposals that are intended to fairly equal the competition are especially encouraged.  Click here to view the 2009 rules.  To submit a proposal send it with your name and contact information to wmra2010@aol.com.

cas utilizing any engine other then: esslinger, ed pink ford, new generation fontana, toyota, or mopar. will be allowed to run the 131 compound 23.5-12-13gt right rear tire.
 
i think a softer right rear tire will help improve how competitive a car utilizing a lower horsepower engine will be. and also I talked with nick behn, and the pricing on the tire is the same. so you will get a more competitive car without spending anything extra.

Rule Proposal:

 

Older Gaerte / Fontana engines to be allowed 181 cu. in. max.

To qualify, cross flow cylinder heads must be 23°, 18°, or 15° minimum valve angle, siamesed port design.

In the case of Fontana / Arias non cross flow cylinder head, must be of 2000 or earlier design.

No symmetrical port heads allowed.

Fontana, Rodeck, or Gaerte blocks will be allowed.

Just some comments about my engine rule proposal to allow 181 cu. in. on some combinations. In looking around at midgets, I notice a lot of Gaertes and Fontanas that are not being run. The primary reason given is that they just aren’t competitive anymore. Current rules allow 166 cu. in. and having dynoed a half dozen different Gaertes and two older Fontanas, I see that most make about 330 h.p. tops when fresh. The best Gaerte number I’ve ever seen was 350 h.p. and that motor was fragile at 15.5:1 compression. Allowing this extra 15 cu. inches would add about 25 h.p. and would put these older engines back in touch with today’s later designs. I believe that this would encourage some of the teams with mothballed cars to return to competition. Also important is the fact that this could be done very reasonably. Most of the Gaertes have a 3.250 stroke and a 4.020 or 4.030 bore depending on how many times they have been freshened. 4.030 gives 166 cu. in. after this you must replace all four sleeves and re-hone to return to legal size. This costs about $1000 to $1200 with no power gain. This could be a factor as to whether or not to quit. With just a crankshaft change to 3.500 stroke and a set of commonly available pistons you would have 179 cu. in. for approximately $2000. This includes $1500 for a crank and $500 for a set of pistons. This would mean that you could hone out your block as far as 4.040 and still be legal at 180 cu. in. instead of putting four new sleeves in that worn-out old block. Pistons for this combination would be the same as a 350 Chevy V-8 and are available anywhere. The low speed torque that would come from the extra ¼ in of stroke would mean that you could turn this combination less r.p.m. and still be competitive. A 7600 r.p.m. engine would last several seasons and be very reliable. I don’t know what else you could do to these older cars for $2000 to $2500 that would help them to be competitive and encourage their return to competition. Concerning the suggested 200 cu. in. allowance, this would require a new oilpan and probably would mean raising the engine to allow the deeper pan. Plus, a 200 cu. in. engine would be fragile with potential cracking of the main webs and, on top of that, might be too fast!

I propose that under the red flag one crew member per car be allowed to check or change air pressures in the tires only.  tools allowed an air gauge and an air tank only   

Glen Seidelman

 

I propose to allow Electronic Methanol Fuel injection with programmable ECU's for Regional cars only. 
 
Steve Hora

 

1    Reinstate the rule allowing Electronic fuel injection for Regional cars.
 
2    Regional cars to weigh the same as National cars, not more as the rules are
      now.
 

Dick Voss

 


1. Only two new tires allowed per race.

2. Full invert.

3. 3 passing points awarded for every car you pass in the main.( hopefully this will cut down on sandbagging)

4. Double Qualifying points.( again to cut down on sandbagging)

5. Open up C.I. for older engines.With a max of 200 C.I.

Scott Livernash

 

Cars powered by four cylinder, horizontally-opposed, two valves per cylinder, intake and exhaust valves, in-line and on
the same axis, must weigh a minimum of 980 pounds with driver. 

Dave Hoene

 


I would like to propose a C.I. increase to 181 for older Gaerte engines:

Chevy 18 degree and -12 only. 

This would bring power output of these older engines up approximately 30 h.p. which I believe would equalize them nicely with the more modern 165 c.i. engines. To allow 200 c.i. versions of these motors would make them very fast, but very fragile.
