CAMS Logbook Advice

[forcedfive]

I am about to logbook my car. It is an NB8A with t25 turbo. Can anyone give me some advice on what category the car should be logged booked under? Is it 2B Marque Sports Car. Also, any recomendations for pre logbook scrutineers thay have use in Sydney. I am located in Gladesville.

Cheers

Hi mate

Whilst 2B rules are not the most restrictive of the classes there are pretty tight boundaries. I think you need to have an SP to comply. 2B regs are on the CAMS website.

CAMS has an extensive list of scrut's, bound to be one close to you.

What mazmad said. I would add it would have been better to build the car to a set of rules than try and find where in the rules your car fits. The rules are simply if it is not stated you can't do it and if it is stated only to the extent stated.

2B Rules
1.6 FREE: A component, deemed to be free under these regulations may, where fitted to the vehicle as standard,
be removed or replaced. Where the removed component is replaced, the replacement is not restricted in
design or material (unless otherwise specified) providing it performs only the same function. No modification
may be made to surrounding components or bodywork to which the replacement is fitted, unless otherwise
permitted. Where freedom is granted for the fitment of any component, such freedom is restricted to that
component and such modifications as are allowed in Article 3.11. For the purpose of this article, a component
shall be deemed to include all other components with which it is integrated, or to which it is attached by
means the manufacturer intended to be permanent. Where a system is deemed as free, all components solely
associated with that system are regarded as free, as per above.

4. ENGINE
4.1 GENERAL: Engine capacity for reciprocating engines may be varied within the limits of the recognised
or replacement block; save that the maximum permitted capacity of the engine is 6000cc. Save for the
restrictions imposed in Articles 1.4, 4.2, 4.3 and 4.4, the remainder of the engine assembly and associated
systems are free.

4.2 RECIPROCATING ENGINES:
(i) The cylinder head/s must be those that were standard for that particular model. The cylinder head/s may be
modified only by the removal of metal.
(ii) The cylinder block may be replaced by another of the same family of block, which is deemed to be one that:
• is from the same manufacturer
• has the same cylinder bore spacing and general configuration.
• retains the same cylinder head bolt positions.
(iii) The cylinder block may be modified only by the removal of metal, whilst retaining the original configuration.

4.3 ROTARY ENGINES:
The rotor housings and end and intermediate plates must be those that were standard
for that particular model. The inlet ports in the end and intermediate plates may be modified by the removal
of metal, including bridge-porting, but the original O-ring seals must remain unmodified and in their original
location.

4.4 SUPERCHARGING:
(i) Supercharging is not permitted unless fitted as standard to the particular model.
(ii) If supercharging is recognised as standard production for the model, the production inlet manifold and
supercharging device must be retained as per the manufacturer’s design specifications. The boost pressure
may be altered. The drive pulleys of a mechanical supercharger may be modified to alter drive speed.

4.5 OIL SYSTEM:
Dry sump systems are permitted. The oil tank must be situated in the luggage compartment
where possible or otherwise fully shielded from the cockpit. Oil lines may pass through the cockpit provided
they are insulated and there are no joins save those at the front or rear bulkheads.

4.6 EXHAUST:
For turbosupercharged vehicles the exhaust manifold and turbosupercharger must remain as
standard. The complete exhaust system is free downstream of the exit from the turbo housing. For other
engine configurations, the exhaust is free from the cylinder head exhaust port. The original exhaust mounting
brackets may be removed and additional brackets may be fitted, provided that their sole function is the
location of the exhaust.

4.7 ENGINE MOUNTS:
Engine mounts, being components fitted between the cylinder block and chassis/
crossmember/bodyshell, are free. The engine may be moved within the constraints of the existing bodywork.
Where the engine block fitted is other than the original block or where it is relocated, a scattershield complying
with Schedule M (refer “General Requirements for Cars and Drivers”) must be fitted.

Hiya Verne,

For supersprints, it doesn't really seem to matter. From what it seems to me, as long as you have a log book for some class, you will be fine.

What really matters is whether your car is compliant with the supersprint class you are running. That is part of what targeted scrutiny is about - checking compliance of your car with the rules applicable to the supersprint class you are running. They don't seem to give a fluff about what class your log book says as supersprint classes are not equivalent to CAMS road race classes anyway.

A 2A logbook is probably a straightforward choice for your car. 3D is another possible option - though I have a funny feeling Sports Sedan rules discourage (or prohibit?) open cars. Not sure where that feeling comes from as I can't see that in the rules at the moment.

Thanks Chris. I appreciate it, that was what I was after and the conclusion suspected too after further reading the regs. I want to join you guys in the MX5 Cup so need to get things underway. It looks like 2A is where my car sits and I will have to look at changing my supersprint category if I dont re-register the car.

Magpie, if I was buiding a track car from scratch I would certainly be doing it to the current regs for the class I want to run. I modified this car over 15 years ago and it has mainly been a street car that I now would like to do some more motorsport in so unfortunately I have to work with what I have and don't have the luxury of starting over.

Cheers
Verne

forcedfive lol that is the same mistake I made I having been meaning to get a CAMS log book for my car as well.

Verne, if all you want to do is run MX5 Cup, get yourself a AASA log book and be done with it. You won't have to change supersprint classes (assuming you don't deregister), and you don't have to choose a class AFAIK...
