Its been a while since I bothered looking at the rules..
I see the 800cm^2 limit is gone from Street A. 650cm^2, so I guess were back to Odyssey 1700 or G34 Optima's there ?

We're back to single amps in StA too.. I assume the duel board style with internal strapping are out, and so are strapping pairs. So whats that leave us with ? 2-3Kw mono's & 2 channels again ?

he lives.


LoL


welcome man.

I came back thinking the exact same things.


SSS_Hoon

Brad runs a Atomic AT-5000.1 on a D-31 with no probs sorry I mean D34.
Your right internaly strapped are out and only one amp total.

i was also looking at getting back into it

mmmm

same as tara she runs the biggest Yellow Top. and a DD Z1A. numbers in ST A hasnt suffered to much competitors are doing round the 150-151 mark at the moment.

isnt the big yellow top over 650ci?

I believe so, it's very close to the 2150, just taller and not a wide iirc.

Maybe Billy is thinking of the D34 size ?

nope im not mistaken or thinking of the little yellow top its the D31 im talking about, the biggest yellow top you can get they are using in Street A.

it comes in at 640 cubic inches if you measure each individual cell and then the top plate, then add everything together its under 650 angelo even measured one to make sure it was legal for Street A.

but yes you can use the big bad D31 yellow top for street A. Thats what tara uses.


cheers billy

Yup it took me a couple days to work it out and double check and research and it actually come in at around 620 give or take if you break the battery down into cells and minus the vacant area under the top plate, so yes they are legal in street A

ah, you could just chuck it in a bucket of water, and see how much volume it displaces!

however, thats really dodgy, it should be the external dimensions, not the actual volume it displaces.

http://audioforum.termpro.com/cgi-bin/ubb/...ic/22/4813.html

Scroll down to where it gets into it.

so, from the actual rules, as quoted in that thread:

"* The physical size of each battery is calculated from the physical dimensions of the battery. (Height x Length x Width excluding the battery terminals) The physical shape of the battery is irrelevant."

The D31 is NOT allowed in Street A.

I'm glad the rules are clear about this.

Absorbed Power GT12-90C is 305x168x208mm externally which comes into 650inch^3 I'm pretty certain. 700cca and 90A/H, worth looking at I think.

just, 649 inches CUBED! (stop saying squared people!, and stop saying centimeters!)

edit * completely misread above posts nothing to see here

Didn't Angelo OK it after speaking to dB Drag in the USA?

Phil

Yup sure did but why argue with the Professors of this site its not worth it and it doesn't say anything that a d31 is not allowed it says its pysical size has to be under 650 but hey who cars most of those who are protesting dont compete in street A

"most of those" there is only one arguing (well in here there is), but it's no surprise, some people just seem to like arguing for the sake of it

but by the clear rules, the battery isn't allowed, so why is it?

because Angelo gave it the OK

why have specific written rules then?

because sometimes even "clear rules" have grey areas.

Based on the size by manufacturer specs (which is what I personally believe it should be) the battery is over, but if you interpret the rule below



the battery is legal as its "physical size" is within the size limit.

But I don't give a rats a.ss, it's not a problem I have to contend with anymore

but its not in the rules, its physical, external dimensions, put it out of the rules.

the list dimensions, NOT the batteries actual displacement.

it actually lists both - the rules are ambiguous at best in that in one sentence the req is volume, then the other it is ext physical dimensions, The official ruling has given it the green light and as its there role to interpret the rules all is good

so, nothing has really changed battery wise for Street A then, what was the point in changing the rules?

this also means, that a manufacturer could release a larger battery that would be allowed in Street B, by using the same design as the batteries we're discussing here...

hmmm - the thing is the actual physical displacement of the group 31's is less then the 650, so however you shape a battery it still must be under this volume to be legal - if you make a donut battery how is the legality determined?

Like alot of rules in dB Drag, it's always going to be open to interpretation.

To me, physical size simply means LxWxH, not LxWxH - whatever "free air" there may be under the top plate.


The way I think the rule should be written is something like this:

The physical size of each battery is calculated from the manufacturer provided dimensions of the battery. (Height x Length x Width excluding the battery terminals)

In such instance that the manufacturer doesn't provide dimensions, the straight line measurements of Height x Length x Width excluding the battery terminals will be used.

THAT is a clear rule

That is exactly how I interpret the current rules, but if it were written that way it would clear up all confusion for some people I think. But I really couldn't give a rat's arse about what's legal and what's not anymore, but I think it would be good to see every competition follow the same rulings or what's the point of competing?

TheyDontWantMusic, if you are so worried about the interpretation of this rule, why don't you ring, or email Angelo?

I'm also a judge and I'm saying:the optima is NOT legal for street A!

so, depending on the country I'm in, I can, or can't use the D31

nice

if the Optima D31 is allowed, its unfare for other competitors who may not be using an Optima battery, but rather have to use a D34 size battery from another manufacturer to be within the rules.

Next you will be complaining that your Amps is not as big.
If you want a powerful Amp you buy a BIG AMP.
Same with batterys you buy a big powerful battery.
No different.

Well, if they would allowe the group D31 Optima, just because the volume of only the plastic case is calculated, you should do this for EVERY battery.
Look at for example at the Odyssey PC2150 and how much "grooves" and "empty spots" this casing has, what volume does it have...
Impossible to calculated and that is why the rules just state: "shape is irrelevant"

look dude plain and simple when they allowed 2150's why didnt guys go buy them then. because they couldnt afford that much for a battery.

why dont they go buy a D31 same reason they cant afford them really or dont want to pay that much for the D31

so then people like you complain that its not fair.

its simple if you want to win you need to spend the money. did you see us having a big hoorah when the rules changed yes everyone was annoyed but in the end we copped it and now just compete to those rules dont we, so just face it the D31 has been given the OK to use.

plus as it also states at the end of the rules:

13-3 All rules will be enforced based upon their intent and the ruling of the head judge is final.


Angelo being the head judge of dbdragracing Australia his decision its final so winge all you want in the end its how it is.
Wayne ok'd it so its final.


NEXT SUBJECT

except, for the physical limitations that ban all batteries larger than 650 cubic inches, except of course the D31 Optima.

GET OVER IT THE OPTIMA D31'S WERE GIVEN THE OK TO USE
IT WILL NOT CHANGE IT WILL STAY THAT WAY OK.

SO I SAY AGAIN GET OVER IT

so, if the Optima D31's are allowed, then any manifacturers D31 size battery should be allowed?

And this thread shows why dB Drag rules are so far up the sh.it it isn't funny.

2 different judges, both rule differently, its a load of crap.

If the rules were written to be clearly understood, (rather than have soooo many grey areas) threads wouldn't turn into ones such as this.

Billy......settle down man.

the optimas D31 fully manufatured size is less then 650. it isnt listed with all its measurements if you wanted it to fit into a box those are the measurements you need the box to be. they dont list the batteries actual physical measurements

where as the odyssey 2150 which you are trying to say fits,,, lists the full outer cases measurements and it no where near falls under 650.

so yes if a manufacturer comes out with a battery that physically fits under 650 then contact angelo im sure he will approve it if it does.



thats it for me.

by changing the rules, they haven't made it so a smaller battery has to be used, they've made it so you either use a D31 Optima, or you use a chemically/electrically smaller battery.

What was the point in changing the rules about battery size then?

so that 2150's and multicell batteries like the DD battery and SPL batteries that are 800 cubic inches couldnt be used in street classes thats why.

2x

but that can be read in two ways!

shape is irrelevant, in that, it doesn't matter the shape, its just the external dimensions that are considered, or

shape is irrelevant, and that its the actual volume of the battery that is to be considered.

HOWEVER, they DO state length X width X height.

Only Street A was reduced to 650 cubic inches.

Phil

yes, I know that, and all thats done has limited Street A to either the D31 optima, or a smaller, other brand battery.

so, people either use the Optima, or, they don't win

Yes now your getting it

Ding ding ding!! We have a winner!

The rules clearly state HOW to measure the volume: lenght x width x height

lol good times, but im with the music and dieter on this one

thats exactly right!

why state length X width X depth, and not state to submerge the battery in water, to measures its actual, accurate, exact volume displacement.

by the current given rules, the D31 Optima isn't allowed! and thats quite clear!

Don't forget the D31 are cylinders, you can't count fresh air as volume.

How about just waiting until Angelo replies and gives the offical ruling!
