2013 Atlantic Championship Series engine rules.

[bill gillespie]

Am I reading the rules correctly that the 1800cc Toyotas are not allowed, and the Swift 016 runs without the SIR required by SCCA Club racing ?

How are the 10k (1600cc) and 8k (2300cc) rev limits regulated/ teched ??

Regards,
Bill

[Bob Wright]

Yes you did read that, but never fear, we're adjusting the whole package per a lot of input by some smart people over the last couple of weeks. Its a work in progress so stay tuned to next week; we'll post the latest version on our website.

[bill gillespie]

Many thanks, Bob/Mike/ et al....I have my popcorn ready !!

[Mike Williams]

It looks like now the swift 016 / 2.3 has a rev limit of 8200 w/ a 34 mm SIR, where did this test or info come from??

[Mike Williams]

Also a weight gain of 15lbs.

[Paul LeCain]

The new rules also say that a 1615cc engine in a Ralt has 2 valves/cylinder instead of 4.

I assume that's a typo. Right, guys?

[Bob Wright]

Already caught it...and some other things we either missed in the proof read or didn't know about. Amazing how many little points come out of the woodwork when a bunch of knowledgeable people really study something. At least we're fixing them in October instead of April.

New rules available at http://www.atlanticchampionshipseries.com/ (right side, by the news image rotator on the top)

Rules are as of 10-23-12

[Mike Williams]

So has the link not been updated, still says the 016 /2.3 34 mm SIR ,8200 and 1435lbs. Cosworth dosent recomend this motor to spin past 8000, who is going to change the map or have access to the ecu?

[Stan Clayton]

Bob, congrats on setting a much fairer engine/wt table than what the CRB is imposing in SCCA for 2013. If your races weren't 3000 miles tow each way, we'd love to come out to play.

What I am curious about is how your series intends to enforce the RPM limits?

Thanks, Stan

[Purple Frog]

question: how will rev limiting be implemented and policed?

Answer:
a. with a heavy hammer applied to the driver's non-helmeted head.
b. New sonic track-side measuring devices proprietary to the Series.
c. Invasion into car data.
d. Honor system.
e. Rick K (Series staff) is working on code for different ECUs.
f. All of the above

[bill gillespie]

Your Purpleness,

Any official word on the 25# sequential penalty on the 1615 Ralt vs. no penalty on the 1800 Ralt ?

Thanks,
Bill

[Dennis Valet]

Section B.2 has the 016 with a 34mm restrictor on the 2.3 @ 1435 lbs...

Then the engine table has the 016 with a 34mm restrictor on the 2.3 @ 1450 lbs...


Am I missing something or is it just an inconsistency?

[Purple Frog]

We like inconsistency. Then we can enforce whichever one we like that day. Dole and Fahan can be 1435, but KHill says he can't get under 1450, so 1435 is for some, 1450 for others.

Seriously, we have been massaging this 8 times per day for the last week... look like a "cut and paste" error. I go back and research which one won Bob's coin flip.

OBTW....It almost doesn't matter unless you have a driver under 165 lb. and a brand new car with no repaired bodywork and mag wheels.

Back to you. Looked at Bob's version... 1435

[Stan Clayton]

question: how will rev limiting be implemented and policed?

Answer:
b. New sonic track-side measuring devices proprietary to the Series.

Anybody can do this by feeding the audio track into a fast fourier transform program/macro. I use the one in Excel.

c. Invasion into car data.
d. Honor system.
e. Rick K (Series staff) is working on code for different ECUs.
f. All of the above

Good luck with that. One reason the old pro series abandoned the ECU used on the Ralt, which they claimed limited the engines to 9800 RPM, was the ease with which teams spoofed the tach signal. Even F1 could not control RPM (not to mention traction control...), and eventually imposed a spec ECU.

With limits as high as you've permitted them, you could always just fall back on the "block ventilation" RPM limiter.

Bump

[Purple Frog]

Damn! Forgot to fix that on the 10:32 update.

Any Ralt with seq. shifter gets the 25# penalty.

Next time we have Monty post a new version on the website, it will be there.

[KevinFirlein]

not to mention that Loyning password protects his ECU's so clients cant accidently hit the wrong button and screw them up. You have acess to the ECU d/l'ed info but not access to the rev limit and the ability to change it. I am sure you could explain the deal and get it but the series sure wouldnt be hooking into my FA ECU and poking about. They would be more then welcome to look over my shoulder though to verify the limit was there.

no penalty for FI ? Dont care, just didnt see one that all.

[Purple Frog]

FI was assumed to be in use in the front running cars, so it was factored in from the get go.
Quick research showed only one Ralt with seg shift, so we designed the rule for Ralts without seq shift, and added weight for those that adopt.

There is a place for RT4, 008, etc. Honestly we need to see entries before we write detailed rules for them. For now they are covered in Section B.1.

[HazelNut]

we need to see entries before we write detailed rules

Every FA meeting this season should have been started with that statement........

Anyone else seeing just a mash of black and blue smudges and no text when they download the rules .pdf?

Is it 'cause I'm on a Mac? :-(

[Purple Frog]

Macs don't like pdf, it's below their stature to handle such crude code.

We could put a stamp on a envelope and mail it to you.

No problem here. Of course I don't like to update software unless I am having issues with current versions (extremely rare). It seems the newer versions create more compatability issues than problems they solve.

I am running 10.5.8 (most recent version of Leopard, before Snow-Leopard) and my Adobe Reader is 9.2.0

I did come across something that required a newer version of Adobe; I installed it and then had issues with printing other pdf's back to 9.2.0 and no problems.

MOST of the front running cars.

I know you can't please everyone but a 25# reduction for carbs would be nice to see.

Hey Paul,

Can you get down to 1175# on your Ralt ??

Bill

[Paul LeCain]

1175 would take a little work.

1225 this year wasn't a problem. The only thing we did was remove ballast.

We still have a 21# battery. Can easily gain some there.
We have an old set of tunnels and pod covers. I have some that are lighter that I need to fit to the car.

All the hoses are stainless covered, not StartLite.

And we had a 195# driver (who now weighs about 175#).

So, we could get close.

The last weight these things ran at in the old Pro series was 1187.

[bill gillespie]

For 2013, are the following legal, or illegal per the new rules package :

1. Alloy BDD blocks from S Jennings Racing

2. Replacement 4AG blocks by Elite Engines

3. Replacement 4AG heads by Preston

Thanks in advance,
Bill

[Purple Frog]

1. Alloy BDD blocks from S Jennings Racing

NOT presently, but we might consider in older chassis such as RT4, DB4.
We would need to hear the pros-cons from guys that are going to run the Series. We will listen to customer's opinions. e.g. I'm thinking of possibility of letting Paul run at 1188.
We were primarily focused on RT41, 014, and 016 chassis in this version of rules.

2. Replacement 4AG blocks by Elite Engines

Must be OEM parts

3. Replacement 4AG heads by Preston

Must be OEM parts

[sherwood]

Boy the 008a guys must feel like red headed step children, like they don't exist
ouch

[Purple Frog]

No one "doesn't exist". The version of rules is based on the interest we received in three summit meetings from the past season, and entries for next season (2013). Any one with a FA that is serious about entering the Series should contact us. We will work with them. Obviously we don't want to work for days/weeks on rules for cars that have no intention of entering a pro series.
From our experience in 2012, this is a serious Series. It is not designed to be "trophy for everyone" Series.
