    Eric is acting as HSAX director I believe..... We made proposals and voted. some passed some failed. Next step I think is he presents to council and then they are voted on to be updated in the gcr.

    a couple I know of that passed are street tire classes being allowed to port and polish stock heads, allowance of aftermarket ECU or computer tune in all street classes but not allowing increase of boost. The boost thing was touchy...... Mainly because it is key strokes to pick up an extra hundred hp so that one will need to be addressed in the future. Not my battle because I run real tires.

    deletion of points for rim diameter
    deletion of points for injector or carb change
    2 points for intake manifold change

    Modified point assesment for intercooler change and addition.

    Official stuff will be posted soon.

    I don't think the points can be adjusted so it is an even playing field for all mods and all cars. Without compelling problems, I'd say no need to fix.

    Hopefully the committee will discuss the proposal at the meeting Saturday and make a decision then. Sorry I will miss the event.

    Some of the points assesments are out of wack..... 3 points for intake and injectors/carb vs 2 points for cam swap or cyl heads.... you get more bang for the buck out of a cam or heads than an intake. Thats why I am proposing the 2 points for the intake. Its possible to pick up 10+ hp out of an intake swap.

Its a supporting mod, so why get wacked twice for one mod?
    Good point. I would still look into what benefit I can get out of some change with whatever car I have. Lots of adjustable fuel regulator companies at least make claims of better performance, and I'm sure I could find a half HP somewhere. Also I could consider manifold swap and stay in stock class, cause I could upgrade the fuel metering to match and still use only 2 points.

    Looks like the purpose of the proposed change is to lower the points of carb + manifold swaps from 3 to 2 and allow unrestricted carb and fuel injection changes. I'm against it because it lowers the barrier (in points) for modifications to too few points.

    I like the proposal for allowing wheel diameter changes without points. It allows drivers who show up with huge rims to not be penalized and it allows downsizing, for example from 17" to 16", to save money because smaller rubber is cheaper.

    I have the same opinion on the proposal elsewhere to eliminate points from all bushing swaps. The points serve an essential purpose: to deter people from spending money on this type of modification. Should be left as-is.

    I have an additional rule change that I plan to propose:

    CHANGE #1
    I propose the deletion of point assessment for Carburetor or Fuel Injection Revision section 6.3:
    "Carburetor or fuel injection revision on stock manifold ………2 pts” and “Carburetor or fuel injection revision with non-stock manifold……. 3pts”

    CHANGE #2
    I propose the modification of point assessment for Intake manifold change section 6.3:

    Current: “Intake manifold change or adaptor without carb or fuel injection change……. 1pt”

    Proposed: “Intake manifold change, modification or adaptor………. 2 pts”


    From GCR:
    Engine
    Engine displacement change (per each 3% increase) 1
    Engine swap, all engine swaps will be classed in the appropriate Race or Street Tire Class
    Removal or tampering with emission control device, per device 1
    Removal of catalytic converter(s) 1
    Intake manifold change or adaptor without carb or fuel injection change 1
    Carburetor or fuel injection revision on stock manifold 2
    Carburetor or fuel injection revision with non-stock manifold 3
    Air intake modification (air box) excluding filter element change 1
    Camshaft change 2
    Valve size change and/or head modifications 2

    Rules change for HSAX 2014 season

    I originally had this in the HSAX section. Moving it here.
    See original post for some of the previous discussion.
    http://mcscc.org/forum/showthread.php?t=1775

    --------------------------------------------------------------------------------

    I want to get this started early so we can have a good list put together by the rule-a-thon.

    I discussed this one with a few people and they seem to be in favor of it.

    I am proposing to remove the point assessment for change in wheel DIAMETER.

    "Change of rim diameter, per full inch increment (up to 16” = 0; greater
    than 16” = 1 per inch from stock; Decrease in rim diameter from stock = 1 point per inch) varies"

    I don't see any real advantage or disadvantage with changing. Yes, there may be a slight advantage of effective gear ratio by going smaller, but as far as effect to times.... I really don't see any. I think this will allow people who are on a budget to use what they want with out the point penality.

    I definitely think we need to keep the rim width point assessment. That does allow you to run a wider tire that does yeild an advantage.

    thoughts?

    Confusion, sorry

    Another suggestion would be to make a separate discussion for pointed HSAX rules like we have already for street tire class rules.

    Sorry, what I meant say was we already have a discussion going on rule changes for RAT. Some proposed changes may get lost if comments are in two places in the forum.

    Tire Wheel (rim) points changes.

    This is timely. Due to the recent wheel size increases on newer cars, 16 to17, 17 to 18, etc. not every high performance tire tread design is made in every rim size or width. Thus some older cars have to take points to run best available tires.

    But I also know that there can be some gear ratio advantages to increasing rim/tire diameter on some of the tracks we run. Example would be if you have to upshift with stock rim diameter but using a larger rim/tire diameter would allow you stay in the lower gear and not have to shift.

    Another suggestion would be to make a separate discussion for pointed HSAX rules like we have already for street tire class rules.

    if you do the larger aspect ratio you are canceling out the effect because you will roll the sidewall of the tire but if you keep the same sidewall height yes your gear ratio changes but you are getting more tire hitting the ground


    in my opinion
    The sidewall part of your comment would be accurate, but in the test I was referring to it was minimal. They were starting with a short sidewall to start with and only went from a 40 to a 45 so not much difference in tire roll over there. If we're talking older cars with 60 or 65 aspects I think your point would come into play much more.
