Improved Production
Hello All,
First post in this forum but have been reading about it for a while.
I'm planning building a bug to run in the improved production (3J) class in some NSW hill climbs. I wont be able to start for at least 2 years
though, I'm currently living/working in Shanghai, not many ACVW's here. So for now it's a plan.
I figure I'll start out slow and work on the suspension/my driving before I build a proper race engine. I've got about a car and a halfs worth of
beelte parts in my parents shed.
I've got a few specific questions about the regs in the class and was hoping I might get some answers from some of you guys running in that class.
1. What about swing axle to IRS conversions? Do you need to run a car already with IRS, can you swap the pan?
2. Is it legal to run the 'Kaffer Bar' type setups?
3. Are any of your race cars road registered? Or do you trailer them?
...I'm sure I'll think of more later. Thanks. |

Gday michael.
Can you swap rear suspension? Pretty sure you can , i believe suspension is free check at cams website for confirmation.
Kaffer type bars, yes they are ok
Rego? My car is not registered but i used to drive it to and from events. So choice is yours, i believe Greg Ward still drives his car to events.
Cheers Col

Thanks Col, I've read over the rules a few times but there are a few things that aren't quite clear.
Since the engine is 'free', except the VW sourced flat 4 block, is anyone runing a TIV or even a water cooled in this class? |

Dont quote me though but I dont think you can use a T4 engine as it does not actually qualify as the donor engine has to be from a passenger sedan/car
from the same manufactor. A T4 engine from a kombie is not a passenger car and its classified as a commercial vehicle. As far as a golf turbo goes,
the engine has to be the same configuration ie. flat four, in line etc..best to check the regs for a 100% qualified answer though.

IRS conversion... hmm... not sure... but if the conversion is done well, how could anyone tell it wasn't a semi-auto converted to manual ??? Pan swap
would be fine, since the chassis number IS the car so you're actually swapping the body not the pan.
Kafer bars - yup - definitely OK - and definitely worth having.
Rego - although my car is fully registered I still usually trailer it to and from events. Call me soft, but a 40km drive each way in a VERY loud car
with no sound proofing or air con... not really my idea of fun !!!
On the different engine setups... Golf is definitely out like bat69 says, but as for Type IV's... well, didn't the 411/412 have Type IV engines ???

That would be open to interpretation of the rules on the day. 10 years ago you would have been 100% correct as commercial vehicles were specifically
excluded. Utes and vans had to run in formula libre! Now its pretty much either vehicles listed as touring cars with FIA, or cars having sold over 200
from a dealer network in Australia. When the rule was changed I was able to run my kombi in other classes wherever I took it, but I reckon if you came
across a scrutineer who reads it differently then you could be in trouble. Is a kombi a car? Is a type 4 on the FIA list? Were 200 sold in Australia
through VW dealers? Its hair splitting and I dont think you would ever have trouble unless you are winning and someone else cant deal with it.
If on the off chance you got pulled up, your defence lawyer would say that the rule was changed 10 years ago to allow Holden to run utes in the 12
hour at Bathurst. Commercials are now cars too. You dont need much proof. How many SS utes do you see with cememnt mixers in the back. Not many. most
have hard covers over the trays.

Had i quick look in the CAMS manuel i have and my understanding is that a type 4 motor would not qualify for improved production class as a vw beetle
was not mass produced with that engine style.
I think that would put you into sports sedan class.
For a definate ruling you can contact CAMS and ask for a technical rep to give you advice.
You wouldn,t want to develop a type 4 motor to have it knocked back, best to check.

naaah. Plenty of datto 1600's running around with FJ20's etc 3J.
The only sticking point is whether the type 4 engine is classed as a production car engine in Australia. I'm not convinced its the ideal choice
anyway. More expensive to build, limited exhaust ports, extra weight hanging out behind the rear axle.

Interesting, I didn't even think about the TIV comming from a commercial vehicle. I wouldn't use it anyway because, as amazeer said, there is to
much weight in it. A 66 x 98 = 1991cc engine would be interesting though
Thanks for all the replys guys. |
