Definitely looking for aftermarket light panel to be allowed.

Can you please elaborate on the part involved and the reason for the change. Thanks

currently the header panel where the lights are has to be oem. Lights can be deleted, pop up panels sealed with seam filler but has to be oem steel panel vs. Gt racing or hairy glass fibreglass version. I run the proper panel however it would be easier to run fibreglass. No weight advantage. A bunch of us wrote to [email protected] (Walt) but it was after deadline.

Yes, saw this issue come up on social media last season. PCA open season for submitting proposed rules changes goes til June. Suggest resubmitting your proposal to Walt asap. Have not heard much in the way of objections and would expect the change to go thru.

Thanks

Current Rule: SP2 requires the stock DME be used.

Proposed Change Submitted to PCA:

Allow SP2 2.5L cars to use the Focus 9 Technology 944-Spec DME to replace the stock DME/ECU. Reliabilty of stock DME's has become an issue due to the decades of use. This proposal provides a reasonable priced option with better reliability and stock performance.

Default Proposed rule change

purposed change is max Dyno HP for class. This is the only way to really control the engine mods as we all know it's to difficult to inspect every part internally on someones car. But it allows racers to build a motor for longevity

I would second the Focus 9 DME as well as max HP. I think a range of HP may be better?

thanks. Jon

For quite a few years I attempted to convince PCA to use a dyno and HP and torque limits to patrol the SP944 classes. Use the 944 Cup classes as a demo for proof of concept. No luck. The concern was that dyno results can be unreliable and possibly manipulated.

So with no dyno, power limits become useless. There is a new club race chair this year. Possibly if enough drivers make the request, something changes on the issue.

When the 944 Cup was running with NASA, power limits and the dyno were part of our rules. But, the rules needed to change when we came to PCA.

For sure... then it's still on the honour system which is open to interpretation. So dyno is a must... Will chat with some of the others and get more feedback in here. To me spec class we should be all at same level and it's down to ability. In my opinion makes it that much more fun knowing it was all down to driver ability, car placement and focus that day.

Agreed.

Now the dyno can be fooled if a car is equipped with a "switch" that can change the engine mapping. To prevent that, we had gone to a tested and sealed dme. That went by the wayside also when the use of the dyno was eliminated.

But with an inspection of the chip in sp1, think that's all that would be needed

Default Adjustable Ball Joints

Current Rule SP2 Stock rule:

G. Front control arms (A-arms) may be replaced with a part approved by PCA Club Racing or reinforced early factory steel control arms. The mounting locations must remain the same as OEM. End links and ball joints cannot be adjustable. Bump steer kits are not permitted.

Proposed Change:

Revise the above provision to allow for adjustable ball joints. For safety reason allow the suspension to be correctly aligned with adjustable ball joints so as to allow for lowering the car. Control arm and ball joint failures have occurred in the past by not allowing for compensation to the suspension once fully lowered. This provision is already provided for in SP3 with beneficial results.

-------------------------------
Submitted to PCA for consideration

There should be enough data acquired by now to build a +/- acceleration table and they can mount the data collection device in 60 seconds providing the car has the mandatory data plug.

The collection devices are already available at PCA events.

We have had device installed for data retrieval several times, going back 3-4 years ago at season opener at Sebring.

Nobody is holding anything back in qualy and/or race.

Think you are right about the data accumulation. As I understand, this data can be used to locate outliers, but is not as a matter of practice used to DQ cars, but rather target cars for inspection. Then we are back to the problem of getting to and inspecting internal engine parts. An onerous assignment with limited resources.
