2021 Official - Road America Spring - The National Championship


Recommended Posts

@Bill Strong  @Jer   @Chris Huggins  @E. Tyler Pedersen  @Doc  @TAlexander  Can you provide info about the rules?   

1.  How are races scored for championship contenders and under what rules?  Tie breakers?
2.  How are races scored for non-championship contenders and under what rules?
3.  Can a championship contender choose to compete in the non-championship "category". 
4.  How are national championship class points calculated (Mazda Contingency) 
5.  Are there MOV penalties for championship and non-championship winners?
6.  What side of the track will sound be taken?

7.  Will the pace car pull the championship contender leader, or race leader?

We are 12 days away from the test day, 13 days away from the first race.   

I've made substantial time and money investments in the car to prepare based on assumptions of the rules, but I think we really need to get to know the actual rules.  It does impact strategy and risk/risk aversion decisions for teams.

ChampCar National Championship at Road America Additional event sponsor gifts brought to you by ChampCar Staff Member Dennis Morgan   Leinenkugel- 1 Hammock, 1Inflatable paddle boat w/oars

I signed us up for this race today!  Looking forward to driving at this course again, but the rest of the driver lineup has not been there before so we decided this would be our bucketlist track for t

I wonder if your BMW will show up to this one or if it'll blow the engine before it leaves the garage. Didnt you say that you were going to be on the podium in the fall?

All good questions, I hope this has been worked out and we have an answer this week. Have you sent any emails?  I will send some today.

Still outstanding and some more:

1.  How are races scored for championship contenders and under what rules?  Tie breakers?  Are non-championship contenders included in the "points" for the winner-take-all championship?
2.  How are races scored for non-championship contenders and under what rules?
3.  Can a championship contender choose to compete in the non-championship "category". 
4.  How are national championship class points calculated (Mazda Contingency) 
5.  Are there MOV penalties for championship and non-championship winners?
6.  What side of the track will sound be taken?

7.  Will the pace car pull the championship contender leader, or race leader?
8.  Will the championship teams use the new digital tech sheets, or should we still print paper?

9.  If I got a one race waiver for 2021 tech but have an annual 2020 tech, can I run the race without getting tech'ed for 2021?

They have been applied to sprint races in the past, so it is a good question. I would have never guessed that MOV would have been applied to 15 minute sprint races, and it cost me a few wins.......sooooo never assume anything.

Email response from Dana on questions I had:

 

  • How will the weekend be scored to determine final champion?  I assume the two finishes will be added together, lowest sum wins.  What are the first and second tie breakers?  Once again I assume season points is first tie breaker, one of the race finishes sets the other.  Assumptions on my part, so please confirm.

Sum of both races based on lowest point count. Tie will be determined at the track.

  • Will the pace car pull in race leader or championship leader?

There’s only one race. The leader of the race is the leader, that’s who we pick up.

  • I think it was previously communicated there is no MOV penalty Sunday for Saturday winner. Please confirm.

Nope.

  • Should championship contenders fill out new digital tech sheet or bring copy of paper tech form?  Last year or this years form for contenders?

Covered in the email I sent.

  • What side of track will sound be measured?

Wherever we feel like measuring it.

  • Has it been determined how the starting order will be done for championship contenders?  I think your email said number of races in 2020 for the first day, has it been decided for the 2nd day?

Haven’t decided on Sunday yet. I plan to ask the teams and get their input on Friday.

Terrific!  I love surprises.  Now do I spend a couple hundred dollars to install a second muffler or waste half of my $350 test day chasing sound again?   What's a few hundred dollars when we are dropping thousands on tires that melt like butter.

Remember that intake roar can also add to your sound total.

I was actually thinking that as well.  It was loud AF at the dyno when I was holding intake pipes together for testing.

That was happening to guys at Laguna seca. They were blowing some big numbers with multiple mufflers. Would light up the throttle in the paddock with the car in neutral, and shhhhh. quiet as can be. They went out on track and the intake roar was what the track was getting. that was hugely loud. 

I saw that Ford put an actual muffler on a Cosworth intake on the Ford Escort Cosworth in the early 70s

Heaven forbid you comply with the intent of the rule rather than the enforcement by actually quieting your car down instead of just pointing the noise to one side or the other.

Three cheers! Great answer.

If they were to take dB from behind then more than half the field would be over 96dB.   

I am running the identical muffler on my street miata as my racecar(Its a street muffler) which is many dB quieter than the Spec Miata exhausts other teams run, but because it points out the side at the sound station, I am over dB.  I am complying with the intent of the rule, but the arbitrary location of metering is the issue.

Are you saying that all the other teams running the Spec Miata mufflers are passing the sound test because they exit out the rear of the car?  If so, then why not just install yours the same way and be done with it?

Flat floor.  There is too much heat under the car for a central exhaust so we made a custom side exhaust and used the quietest muffler that would fit, which happened to be a sport/street muffler.  They make a short and a long version, and we have both which we changed depending on the sound limits.   There is a 1hp difference at peak between the short and the long and a 1hp difference at peak between the short and no muffler.  After we built them we measured out the distance and did dB testing in our cul-de-sac.  We are fine at some races and others we are over.

 

For the championship we will move to a central exhaust anyway, but its frustrating that the rule specifically disadvantages those running a side exhaust.  I don't think the intent of the sound limit is to stop teams from running a flat floor but that is what it is going to do in our case unless we get creative with routing and run it back through the chassis over the wheel well now that the fueler is moved it is possible, just ALOT of cutting.

Regarding tiebreakers:

 

1) I like the idea of season rank breaking a tie in combined finishing position for the weekend. On the other hand, that steers a little away from the idea of “winner take all”  once you qualify.

2) I also like the idea of finishing position on day 2 being the tiebreaker... that way it’s all still to play for on day 2, you can make up for a small slip on day 1.

And IMO "season rank" should be based on the finishing position of the qualifying races (not just the top 2 finishes). So if it's 4...5...whatever, it should be the lowest sum of those races is the "season rank".

I'll suggest using combined laps for the weekend as the first tiebreaker, although there is a reasonable chance that doesn't break a lot of ties it's still logical to look at that before going to prior race results.
