sport compact classes

I was just going through the sport compact classes and have found out that my car won't really fit into a category.
Sport RWD/AWD 2 rotor & 1 power adder min weight 2500lbs
6 cylinder & 1 power adder 3200lbs
My car is has 6 cyl and 1 power adder but will not weigh 3200lbs. I can't see why they would make it like this when my engine is actually less capacity than a 13b (2.6L).
Sport Mod: min weight for my car is 2650lbs which would be pretty close to it. This is because they split the capacity up between above or below 3L. However, this class is pretty crazy and allows slicks, open exhausts and wheelie bars so I don't think I could be competitive.
Oz Mod has the same weight classes as sport mod but has a maximum size slick tyre that can be used. It is also pretty hardcore.
Does anyone else agree with me that the Sport RWD should be divided by capacity as well as cyclinders/rotors?
My car is still a street car and as such I would prefer to race against other street cars rather than mega crazy big $$$$ ones. Anyway.

I have the same problem, and my car is only a 1600cc engine with 1 power adder, but I wouldn't even get close to the minimum weight...
Seems the only thing I could race in is povvo street class, bracket racing against a 15.5 second automatic crumpledoor & getting beaten cause they can run super consistent, dial in within one tenth of a second, but never run fast

I have emailed ANDRA so will see what they have to say.
That sucks as well mate. What is the next time class up in bracket racing? If you could get into that it would be more even.
I just don't want to have to compete against 9 sec cars like the ones in Oz Mod!

Ooh ok, so even in sport rwd/awd there are 9 second cars. I suppose I will see how I go. And as you say consistency is the key. I just don’t want to be 3 seconds slower than everyone else!

12.1 et 118.9 mph but shitty 2.1 sixty foot.
with the heat it wouldnt come up on the convertor which he knew would be a problem carrying on from qld jambo. thinking it would be cooler than it was spent money on fixing suspension. he said it run alot straighter and didnt play up under braking like it did in qld.
i belive he is going to go with a bigger stall to get it into its boost threshold, then should be a lot more consistant. he is looking to run 1.6 - 1.7 sixty foot times on the BF GOODRICh drag radials. which with his MPH of 118 - 119 that equates to 11.2 - 11.3 et's. which is about his goal time to run in the bottom end of super street.

Sounds like a plan.
Just wondering what the stall speed is at present? Is it a modded stock converter or aftermarket? What rpm does boost come in at? What stall speed is he going to get?
Hope that isn’t too many questions Just trying to get my head around this stuff for when I have to choose my torque converter.
Great to see the Toyota’s being represented well!

That is some good information mate. Thanks.
Yeah, I had thought of moving to a C4 or maybe a turbo400 box. I know that you can use a transbrake on these sort of boxes which is obviously an advantage but I am hesitant as it is a fair bit of work as it will need custom bellhousing, kickdown cable, tailshaft. And there is also the hassle of wiring which has already been done now. Would a c4 or turbo400 box still need to be strengthened in the same way they do with an a340e? Or is it just a recondition job and fit the stall converter and you are good to go?

no idea chris
i had a manual when i had my kingswood.
i would assume any transmission would need to be built to handle 400 + horsepower.
do you post under bassaholic55 on peformance forums?

also
you will need to check the sport compact rule book, i think you'll need to stick with the toyota transmission to run in sport rwd other wise you will be put into ET2.
as afar as andra meets go, they dont care, but sport compact events run different rules

Yeah I think you would be correct but I was hoping not
After seeing what Shane and Sean (MS-75) have done with the a340e it makes me want to keep using it as the only real advantage I can see is the transbrake.
Yeah, that is me. Old name and I can’t change it over there.
Ok, I will have another look over the rules tonight. Good point.

Just got a response from Andra. Looks promising
Hi Chris,
At this point in time, there is no need to head down a capacity/ weight
road. We are currently assessing the state of play with weights in all
classes, and a decision about the future direction should be known very
soon.
Your points are very clear and valid, and I will hold them until the time to
mount a case to head in this direction occurs.
I appreciate you taking time to email me your concerns and will endeavor to
take stapes to eliminate the problems your facing.
Cheers for now

I know what you mean J. But at present I still don’t really fit into a class so I will see what happens with these changes and hopefully I will be alright for sport rwd/awd. Once I know for sure what class I will be in, I will then go and learn all the rules.

Hey chris,
I was thinking about your converter speed yesterday, and my suggestion would be to actually have it dynoed with the stock converter in there before you choose a stall speed. The reason is that dynoing cars with largeish converters is difficult, and when they are turboed it's even worse. With a bigber converter, as soon as the operator loads up the rollers, the car flashes out to stall speed, hits the converter, loads up the motor and brings the boost on-all in about 3 seconds. This means the car jumps into the torque band almost instantly and torches the tyres on the rollers-making tuning it as it comes on boost quite difficult. HOWEVER, this instant torque hit is of course exactly what you want at the strip. (I found this when I first went to a big stall auto for the 5M).
The best way to do it is to dyno with the stock converter so you get a good, progressive power delivery to the dyno for ease of tuning, and also note where the boost threshold is, and then have a converter built with a stall just above the boost threshold. It'll cost a little more for the converter change post dyno, but it'll be worth it for the well tuned end result.
How close is the Corona Of Death to turning a tyre in anger?

That was actually my plan. Although I didn't have the first hand experience of dynoing big hp auto cars, I figured that there was no real point in trying to choose a stall converter before I had even driven the car.
So the auto is still stock at the moment so I will be taking it easy for a little bit. It does have one gearbox cooler (front mounted) but I think I will install another one with a fan and use my relay for the radiator thermo fan. I am also installing the oil temp guage in the pan this weekend.
I am aiming for the 21st of May to debut the car (finally!) as the soarer club is heading out to Willowbank so I would like to go with them. Have been working hard on it all the time and it is coming together but the main hassles are waiting for stupid little parts or getting incorrect ones given to me.  But I will persist and it will hit the road soon.
I was actually hoping to get all the undercar stuff done this weekend so it can get some wheels back on it and get off the damn jack stands. Seems like it spends more time on jack stands than with wheels
Later
Chris

This is the new rules for sport compact
Sport RWD: 2 Rotor – 2300 pounds/ 1045kg, 4 Cylinder RWD – 2300 pounds/ 1045kg, 4 Cylinder 4WD – 2400 pounds/ 1090kg, 6 Cylinder RWD – 3100 pounds/ 1409kg, 6 Cylinder 4WD – 3200 pounds/ 1454kg
Bloody hell :mad2: I emailed about getting the <3L and >3L weight brackets included in sport RWD and instead they get rid of it for the oz mod and sport mod 
How can a 6 cylinder 2L have the same minimum weight as a 4.1L???

was trying to find out whether sport rwd over 3200pounds 6 cyl can still run 2 power adders. 1 being turbo, 1 being n20.
i looked at the andra site, cant tell if its been updated yet though.

I thought it said that they got rid of the 1 and 2 power adder brackets and moved into one.
I hope this is not final about the weight brackets.

the rule was
Minimum Weights:
RWD or 4WD 4-cylinder/2-rotor (1 power adder): 2,500 pounds, RWD or 4WD 4-cylinder/2-rotor (2 power adders): 2,750 pounds, RWD or 4WD 5-, 6-cylinder (1 power adder): 3,200 pounds, RWD or 4WD 5-, 6-cylinder (2 power adders): 3,500 pounds, All weights include driver, verified after the run. Refer weight penalties in class regulations.
so that says to me if you wiegh over 3200 pounds you can have 2 power adders. 1 being a turbo 1 being n20.
it would appear ANDRA havent upgraded the new rules yet on the website, which you think they would do prior to releasing it to other area's.

I read the new rules as Min weight 6 cyl with 1 or 2 power adders is now 3100lbs.
That still doesn’t help me though

I was talking to Sean the other night and he mentioned about Shane using some sort of spray similar to a water spray on the intercooler to cool the charge and hopefully bring it up on the converter in warmer weather.
I can’t remember what the stuff was though? I am not sure if that would be allowed as you can’t have water spray.
Did you guys look into this?

i beleive him and sean were talking about a co2 spray setup. its not a water set up
at the sport compact meet, we put a bag of ice on the intake manifold and 2 bags poured down the back of the intercooler in between runs. we then got it dry before going back out onto the track. it did bring the temps down but not enough to a point where we got more stall.
got of the phone to shane a minute ago, he has decided on a bigger stall.
Milan who ran the 11.3 at heathcote is running a 3240 with a 100hp of nos for the entire run. Milan said he is having trouble getting his above 14psi and needs the nos to help get it up.
apparently he is going to put a 2j in it instead of getting cams in his 1j.

Hmm, that is interesting about Milan’s car.
How much higher do you think Shane’s car needs to go?
In my car I would prefer a little higher stall than using N20, even if it is just off the line. I don’t know why, but I am a bit weary.
BTW 2j is cheating

just an update
I was asked by a guy from the sport compact committee to put a request in writing. So I have done that and in it I requested they segment 6cyl >2.9L and <2.9L. I suggested >2.9L be 2700lbs and <2.9 stay at 3100lbs.
He then suggested that maybe 2.5L would be better as there is more smaller capacity engines available.
So we will see what happens.

Just got this email:
Hi Chris,
Thanks for the email concerning the weight parity in the 6 cylinder classification of Pro RWD. As you know we have earmarked the Pro RWD class as the headlining category with minimum rule restrictions. This has been done to develop the class as the fastest and quickest of all ANDRA Sport Compact classes.
The way we will achieve this is to place minimum restrictions on those competitors who wish to push the envelope in a Sport Compact orientated vehicle. Minimum engine restrictions, zero turbo restrictions, minimum weight restrictions…..the list goes on. I am extremely happy with the continual evolution of the Pro RWD field and its racers, and feel that in the next twelve months we will see many more cars joining the ranks.
Unfortunately in the search of performance and class development, there will be those racers who will be eventually left behind. This is a natural progression in any discipline of drag racing, and quite simply the strong will survive. Looking at Top Fuel for instance, the natural progression over the last 30 years has been towards big bore V8 engines that thump out over 4000Hp. No one uses small block Chevy’s or Mopar’s any more as they simply are not competitive enough.
In Sport Compact, the Pro RWD field is the considered by many as the Top Fuelers. These are the guys with the budgets and cars to compete at the very highest level. They apply monstrous HP to equally incredible machines in the search of low 7 sec/ high 6 second times.
Here at ANDRA we are acutely aware of the different levels of commitment people are prepared to make in the sport, and feel our current classes offer a very broad selection to choose from when it comes to racing. We have a class to pretty well cater for all racing needs. Our formats are simple, Head up for the Pro cars and DYO for the classes where performance is more widely varied.
Your request to have engines like the RB20 ‘handicapped’ against the class capacity maximum 4.1L is not practical. I make reference to the fact the Pro RWD field is encouraged to go fast, and encouraged to develop packages that push the limit. The RB20 has never been an engine of choice in the Pro RWD field as it is simply not competitive enough. The capacity of the engine essentially becomes irrelevant when compared to the SR20 4 cylinder, which are renowned for producing similar if not more power, and enjoy a lower weight break.
The RB20 is essentially your engine of choice, and whilst it is catered for in the Pro RWD field, it is done so against engines like the RB30/26 hybrid and 20B rotary that are known 1400hp performers. On the basis that the RB20 is your choice, I cannot alter or suggest the rules be altered to accommodate an engine that is not known for a competitive HP output, and is being used at your discretion.
I realise this will upset you, but please remember the Pro RWD field is the pointy end of the ANDRA Sport Compact classes, where the best of the Sport compete in the very fastest way.
Thank you for your email.
Jason O'Halloran
This is what I wrote:
Dear Sir/Madam,
I am writing in regards to the Sport Compact Sport RWD class weight
brackets. I previously had emailed Jason O'Halloran with my concerns
regarding the possible segmentation of the 6 cylinder class.
The reasoning for this is that the most common engines used in this
class will be 1JZ-2JZ, Rb20-30, VG20-30, 6G72-74 and the Ford Barra240
engine. Therefore, the minimum engine capacity would probably be
around 2L. At present the weight bracket for 6 cylinder cars in Sport
RWD are 6 Cylinder RWD - 3100 pounds/ 1409kg, 6 Cylinder 4WD - 3200
pounds/ 1454kg.
To me, this rule states that a car with a 2L 6 cylinder has to weigh
the same amount as a car with a 4.1L 6 cylinder. It is obvious that
the car with the 4.1L engine is going to have an advantage.
Also, the 2 rotor 13b powered cars have a minimum weight of 2300lbs.
As the 13B is classed as a 2.6L I cannot see how it can have a
possible advantage of 800lbs over a car that could be using a 2L 6
cylinder like an RB20.
I am requesting that the 6 cylinder weight class be split up as there
is a much wider variety of engine that can be used in this class
compared to the 4 cylinder class. I would suggest that a good
segmenting point would be 2.9L. This would see cars using engines
like 2jz-gte, Rb30et, VQ35 and Barra240's racing under the same weight
break. Then cars using engines like 1g-gte, 1jz-gte, vg20det,
rb20det, rb25det and rb26dett would race under the same weight break.
I would suggest that 6 cylinder RWD cars under 2.9L have a minimum
weight of 2700lbs. This is half way between 4 cylinder RWD cars and
the current 6 cylinder RWD cars.
Thanks for taking the time to read this.

Yep, just sent him another one. Also explaining that the RB20 was an example. (No way I would use one! )
I had emailed Chris Diggles who bought it up at the meeting and he said that it was basically put on hold. He said it goes from meeting to Jason O'Halloran then to the top board. And the top board basically don't know shit about sport compact racers as they are all hardcore top fuel lovers etc.
I am awaiting a reply on my latest email from Jason.

my email:
Hi Jason,
I was actually referring to the Sport RWD class not the Pro RWD class.
I understand where you are coming from regarding the Pro class
however.
I just feel that because sport compact is primarily focused on import
cars that segmentation between smaller and larger six cylinders would
be beneficial considering that the majority of import engines are
smaller capacity.
I don't use an RB20 but I was using that as an example of how someone
would be severely disadvantaged if they were. In fact, I am not sure
if an R32 gts-t would be allowed to race because they wouldn't weigh
enough.
I am using a Toyota 1jz-gte in a Toyota Corona. This package has the
potential to match the best cars available in Sport RWD class. The
Corona was chosen, as it is one of the lightest cars the engine can be
put in and still be street legal. This was also done long before the
Sport Compact rules were formulated. The lack of capacity against
larger engines would have been offset by the lighter weight of the
vehicle. However, if my vehicle must weigh the same as a larger
capacity vehicle then I would be severely disadvantaged.
That is not my main issue though. The main issue being that a car
like mine (and there are many others) simply does not have a class to
compete in except the ET brackets.
I am not sure what the quickest times in Sport RWD are, but I was
looking for mid to high 10's out of my car, which I think would be
close to the front of the field except the GTR's. That is if, I am
able to compete.
On a final note, I saw a picture from a recent event held at WSID and
a car I know HYPO77, a 77-model Celica fitted with a 1jz-gte was
racing in Sport RWD. I am 99% sure that this car would not weigh the
required 3200lbs. Do you know how this would happen?
Thanks
Chris Davey
his email:
Hi Chris,
Once again thanks for the email, and more importantly good points that have
been made.
As you are aware of we recently dropped the minimum weights to better
reflect the Australian orientated cars. Previous weights were a direct cut
and shut from the US, and not all cars were adequately represented through
the weights here in Australia.
The new weights come into effect as of 1st of September 2005, and they are
as follows;
Sport RWD:
2 Rotor - 2300 pounds/ 1045kg
4 Cylinder RWD - 2300 pounds/ 1045kg
4 Cylinder 4WD - 2400 pounds/ 1090kg
6 Cylinder RWD - 3100 pounds/ 1409kg
6 Cylinder 4WD - 3200 pounds/ 1454kg
OLD WEIGHTS
RWD or 4WD 4-cylinder/2-rotor (1 power adder): 2,500 pounds,
RWD or 4WD 4-cylinder/2-rotor (2 power adders): 2,750 pounds,
RWD or 4WD 5-, 6-cylinder (1 power adder): 3,200 pounds,
RWD or 4WD 5-, 6-cylinder (2 power adders): 3,500 pounds
You can see we have slashed 100 pounds out of 6 RWD 1 power adder and a
whopping 400 pounds out of 6 RWD running 2 power adders!
As you can imagine it is impossible for us to cater for every engine/ car
configuration, and whilst I understand your plight, there is very little I
can do at this point in time. I suggest you contact you local ANDRA
Division Director, and get them involved.
They represent their respective racers, and are your voice on a national
level. A rule submission to alter an existing rule is not out of the
question, and they will guide you through the process.
I am extremely keen to encourage any potential; racer into the Sport Compact
fold, and make no mistake about it....I want you to race. There is
obviously a problem with your current vehicle and its weight, so I therefore
recommend you contact your local level ANDRA personnel and take matters
further.
I hope this helps in the mean time,
Jason O'Halloran
Doesn't look too good I don't think

Thanks mate
Well the rules look good for your car now don't they!
I wouldn't exactly call myself a lightweight so that should help I will be able to get it weighed very soon. If I get some time, I will do it on saturday at the garbage dump
I am not exactly sure what he meant by my local ANDRA Division member though? If I knew who that person was, I would gladly tell them.

i would suggest that you get on the andra website and get a super street license as you know your things going to be quicker than 12.50
that way you wont get kicked of on your first run. also you get sent regular updates of rule changes and special packages deals for different things, it also gives you a andra rule book which details your local state rep.
all your reps work out of townsville according to my rule book.
the other option would be to go to the next street meet, grab an andra official and ask them who the state rep is.
i have phoned my one on a couple of occasions and they are very helpful and polite, even though we dont drive top fuellers.

i have a question thats prolly gonna make me sound like a n00b but ill ask anyways.
Chris, why should you think your setup will give u a handy cap just because u are racing against engines up to 4.1L?
consider this might give u the opportunity to sort out the car with more precision as you have the chance to put ballast into the car wherever you want, where a heavier car doesnt have the option.
also isnt that what dial your own bracket racing is all about? I recall 1JZ.747 saying on the forums that a WRX had beaten him because it was doing consistant 14.5's all day and he couldnt catch it on his last run?
im asking cause i dont understand why your looking to get the classes changed to suit your car when from what i understand, you dont need to have the fastest and most powerful car to win your class?
hope i made sense cheers

Good question mate.
Yes it is a Dial your own (DYO) class so the field is evened out through that system. The reason I am requesting segmentation is that I am sure there are other cars out there that use 6 cylinder engines and weigh less than 1409kg. So as long as they abide by the other Sport RWD rules like full exhaust, street tyres etc. I don’t see why they cannot race in Sport RWD.
So as long as you can get the car up to minimum weight through extra lead or whatever being bolted in then that is ok because you are then in the field and the DYO system will make it even racing.
The other point being that having a 6cylinder engine doesn’t automatically give you an advantage over a 4 or rotary. I just think it is strange that you can run a 2L 4 cyl at 2300lbs but you would have to run a 2L 6 cyl at 3100lbs.
So the DYO system evens out the racing field but in the end drag racing for me is about going as quick as you can. So if possible, I would like to be able to run it with as little weight as possible in an attempt to go as quick as possible.

wise man once say, its easier to change yourself than to change everybody else.
you have an excellent opportunity to have a very well sorted car in the 3100lbs class using ballast, traction is more important than weight reduction.
i feel you will be more competitive in the 3100lbs class than trying to change the rules so u can be the lightest car with the biggest engine.
and no offence but you shouldnt expect the rules to be written around your car, i understand you bought and built your car before these rules were in place which is unfortunate because the way the game works is that you need to build the car to suit the rules.

I know what you are saying Rob, but Jason has said that the rules were a direct copy of the US rules and as such there will need be to some changes to adapt it to Australian cars. I am just suggesting what I think may be a good idea. It would obviously be great for me, but I am sure there are many other people in Australia in the same situation as me. Ke382tg is one of them
I will talk to this State rep and see what he says. If they segment them, then that would be great and if they don’t then I will just go in an ET class. I just had my heart set on Sport RWD that is all
Oh, and there is no doubt being able to choose where the weight in a vehicle is placed is an advantage. I will hopefully get the car weighed this Saturday so that should clear some things up for me as I still don’t know exactly how much it weighs since all the mods.
