2014 rules posted

[Al F.]

The 2014 rules have been published on the nasaponycars web site. I will post my perspective on the decisions made very soon.

[BADVENM]

Please clarify how "appearance" ie non performance enhancing items should/will be handled/enforced/not enforced at regional events and national championship events. I see that rule 3.5 didn't change from last year which is a contradiction to how things have been done at

national championship events.

 

Will the ruling (which in the past has been non enforcement) be the same at both west and east coast championship events or up to the CMC director in charge at each event if different?

 

For this example lets use the glove box door/cover.

 

3.5 Non-compliance/Cheating

Cheating and non-compliance will not be welcome and will receive harsh penalties. Non-compliance, defined as unintentional violation of CMC or NASA technical specifications will result in a disqualification. Cheating, defined as intentional violation of CMC or NASA technical specifications will result in multiple race disqualifications. The CMC Officials may decrease or increase penalties up to permanent ejection from the series for non-compliance or cheating based on the severity and recurrence of offenses.

fyi, the national site has not been updated. 2013 v2 http://www.nasaproracing.com/rules/Camaro-Mustang-Challenge.pdf

Removed: 7.33.5 Late GM and Late Ford cars may use a threaded collar and adjustable spring seat assembly such as

one available from Ground Control, Global West and Suspension Specialists for the front suspension. The

rear springs shall conform to 7.33.4 above.

 

 

7.33.5 Any spring spacers/shims may be used. The spacers may allow adjustment of the installed

height of the spring without spring removal. The spring spacers/shims must install with the spring in the

OEM stock location and no cutting, welding or other mod

 

Does that mean I have to take the threaded body coilover sleeves off my car or am I reading this wrong and basically this just allows the early cars to be adjustable?

I think the latter. In addition, it looks as though rear adjusters (like the Ground Control pieces) are now legal as well. There is no longer a restriction to the front only that I read.

My concern as well since the rules don't expressly state that the fronts allow coilovers. I believe that was the intent though, so we shall see.

No, it does not. That was not the intent of the rule change. Directors are aware of the wording and will clarify this. Stand by.

[Pranav]

Cool, let us know if the wording changes.

 

Also curious if corner-balancing will be allowed or if the "both sides equal" rule is still in effect.

[wastntim]

I applaud the changes made by the Directors as the rules continue to evolve in a way to make things easier and less expensive for us, i.e. adjustable spring perches, reinforcement for the fords, the 5.3 for the fourth gens, etc.

[D Algozine]

I applaud the changes made by the Directors.

which GC adjusters do you speak of? I've looked around there other dirt-track stores for something useful. however w/o being able to modify the car nor the axle spring perches I have yet to see something that would work. Or perhaps this is for something other than a 4th gen?

 

maybe some kind of adjustable spring perch with a non-pigtail spring on the GMs?

Indeed. You all took an unbelievable amount of back and forth chatter on the forums and distilled it into a handful of relatively small and much needed wording changes for 2014. While I still have my own opinions on a couple of them, I understand them and I can live with them. Success. Lets move forward and get ready for 2014.

 

Somebody should probably contact an Enkei wheel representative and let them know they are going to get a flood of orders for 17x9.5 RPF1s and work on getting some kind of discounted group buy together and post it back here on this forum so everyone can take advantage of it.

 

Same thing goes for 275 wide 17" RRs whenever they become available.

 

Have you seen the response to the dedicated Video section already?!? Holy Smokes. And Heck Yes!

[Al F.]

Yes, threaded coilover sleeves are still allowed on the front of 4th gens since that is where the OE spring resided in the first place.

[Dustin M.]

Can the collars front and rear be set where we please now for cornerweighting? Last I checked, I was within 40# so I probably won't screw with it but it's nice to know you can.

[Dustin M.]

One more little snippet I thought I'd point out. I can't access the rules from this computer, but I seem to recall them calling out 99-04 truck engines and then laying out some RPO codes of the allowed engines. The L33 is one of those engines, but was only produced in 05-06. If it's going to be allowed, the rules need tweaking. Maybe just spec out RPOs and leave the years out of it? Or change the years to 99-06. 07+ is when active fuel management debuted in the trucks IIRC. I also believe that's when they got the LS6 based ports instead of the LS1 based ports and a commensurate bump in output.

[Glenn]

LS1 and LS6 are the same. You may be thinking of LS2/3.

[Dustin M.]

Nope, LS6 uses raised floors and different shapes than the LS1. LS2 heads are straight up LS6 heads with solid valves (casting number 799) and some LS2 even got LS6 castings (243). Some cars have one of each! I guess they were just using what was left. LS1/2/6 are all cathedral ports, but not all cathedral ports are created equal.

[Glenn]

LS1/6 only ran through 02 for the f-body. Those have always been legal. Those are the same heads found on the legal truck motors. No major port changes until the LS2/3 motors. None of those are legal.

The LS6 has very different ports than the LS1. Also, the LS6 never came in the f-body, but 01-02 f-bodies did get the LS6 intake manifold and some lucky recipients even got the better breathing block (less blowby).

 

 

I realize by limiting the years, you're avoiding an LS6/2 based head, but I did a little digging and found that the L33 does in fact use an LS6 based head. It's kind of a moot point though because the restrictor plate will just get smaller to kill those gains. Make no mistake though, the LS6 and LS6 based ports are superior to the LS1 ports and the LS2 ports are unmodified LS6 ports.

[Glenn]

Ok - my bad on the LS2.

 

LS6 did come in 4th gens, just listed on the window sticker. As production came to an end, GM put what they had in the f-body. Plenty of documentation on this. LS6 heads, intakes and in some instances blocks as well were used for 4th gens.

If you go to GM and ask for a head or block for the LS1 4th gen, you will get LS6 parts.

 

So I don't see your point. All LS6 parts have been legal since the LS was legalized. If the truck came with those parts, what is the issue? They were already legal.

 

And I don't call the difference betwen LS1 and LS6 heads a major difference. Most all the platforms have these differences throughout the life of the platform generation.

[Dustin M.]

I think I got hung up on what I perceived as the intent of limiting the years and RPOs of the engines to use as not allowing LS6 ports based on what I'd read. That and the LS1/2/6 differences. And the L33 being an 05-06 motor, but that's an easy fix to the rules by expanding the years to 99-06. AFAIK, the Intimidator was the only Camaro to receive the LS6. I forget which Pontiac got it.

[Dustin M.]

Can the collars front and rear be set where we please now for cornerweighting? Last I checked, I was within 40# so I probably won't screw with it but it's nice to know you can.

 

Per Al's other thread, the answer is yes.

Approved changes for 2014

RCR#3, 7 in favor, 1 against: Everyone can now employ adjustable spring perches to make it easier to corner weigh the car. There are limits as to this; no modifying the front arms or the chassis. We allowed modifications to the rear Ford arms for this because rear aftermarket arms were already allowed.

[supermac]

I have always been under the impression that the 243 head was not legal in CMC? Nor the "LS6" intake?

All 2001+ LS1's have the LS6 intake stock.

[supermac]

Functionally maybe, visually no. I have held both in my hand and they look different.
