TECHNICAL REGULATIONS X30 CHALLENGE ITALY – ENG

ENGLISH VERSION ONLY FOR PRACTICAL PURPOSES. THE OFFICIAL TECHNICAL REGULATIONS FOR X30 MINI IS THE ITALIAN VERSION

TECHNICAL REGULATIONS X30 CHALLENGE ITALY
1. GENERAL
For any non-mentioned regulation in the Technical Regulations X30 Challenge Italy, reference must be made to the as attested by the Technical Regulations of ACI/CSAI.

2. TECHNICAL CONTROLS
Technical controls on the engines will be carried out by the scrutineers of the Federation.
The reference document for the technical controls is the engine technical form.
However, in case of persistent doubts about the absolute originality and compliance of a particular, the necessary element must be compared with the same part belonging to the sample engine, in possession of the Chief of the IAME S.p.A. delegate
Scrutineers have the right to carry out technical checks on the parts to the point of making them unusable. Following a check that turns the particular inoperable, this particular will be refunded only if found original; all the parts turned  unusable as a result of technical inspections and detected as non-genuine, will not be refunded.

3. CLAIMS
In case of dispute, the competitor may present a claim in accordance with the Italian Sport authority’s regulations.

4. ADDITIONAL TECHNICAL CONTROLS
IAME S.p.A., acting as promoter of the X30 Challenge, reserves the right to withdraw any engine after the completion of the technical controls, and perform additional controls at its facilities. Any non-compliance detected by IAME S.p.A. will not affect the ranking of the Event or on the decisions taken by the Technical Scrutineers, however, a report will be drafted and sent to the Entrant together with the decision by IAME S.p.A. not to accept entries to its events by the Competitor whose engine was identified as not in compliance with the regulations. After such additional technical control, the examined engine will be returned to the Entrant, in the shortest delay possible and in the same conditions as it was at the time of the collection, regardless of the outcome of the additional controls. The Competitor who refuses the application of this Article, will be automatically excluded from the events promoted by IAME S.p.A. with final and unappealable decision.

5. MODIFICATIONS TO THE REGULATIONS
In order to ensure the correct execution of the X30 CHALLENGE Italy and / or in case of force majeure, IAME S.p.A. reserves the right to change the articles of the technical regulations as it deems necessary, at any time, subject to authorization by ACI/CSAI.

6. FUEL, LUBRICANT, FUEL TANK
Only fuels commonly sold at service stations are allowed. The choice of the service station for the supply of fuel as well as mandatory octane number will be indicated by the organizer of the event and reported in the Supplementary Regulations.
The fuel must not contain any additive other than the approved lubricant. The only allowed lubricant is Wladoil K2-T, CIK homologated. The tank must be of the removable type and have a minimum capacity of 8 liters (3 for X30 MINI).
Rrecovery tank for the cooling water and fuel tank vents are mandatory.

Only ACI-CSAI homologated chassis with valid or expired homologation for the MINI category are allowed.
Drivers will be allowed one (1) chassis only. However if a damage occurs to the chassis previously scrutinized for the meeting, if in the opinion of the Scrutineers it is not practical to repair in time, one alternative chassis of the same make and model as the damaged chassis may be scrutinized, in order to continue the meeting.

2. DEFINITION OF THE CHASSIS

4. ENGINE
IMPORTANT: the tolerances reported on homologation form are necessary to comprise all the machining, assembling and settling tolerances. Nevertheless, the Entrant is absolutely not allowed to make any intervention on the engine, even if the characteristic dimensions after his intervention will still be within the prescribed tolerances.

Any modification or adjunction on the engine and its accessories, if not expressly authorized, is forbidden. IAME considers as modifications any action changing the initial aspect and dimensions of an original part. Any modification and/or installation having as a consequence to alter a dimension and/or its control possibility is strictly forbidden. Polishing, sandblasting, trimming or adjustments are not allowed. No heat treatment or surface treatment are allowed. The Entrant is liable for the conformity of its own equipment.

Any tuning is forbidden: the maximum and minimum allowed values and the volume of the combustion chamber have to be measured according to the procedure described on the CIK Technical Regulations.

The following original homologation forms of the engine:

  • «364A» IAME X30 WATERSWIFT – 60cc RL TaG

Only the IAME X30 WATERSWIFT 60cc RL TaG, original and strictly in compliance with the manufacturer’s technical form (technical features, sizes, weights, diagrams with the tolerances prescribed by the manufacturer) is admitted. The pictures on the original homologation forms are as well valid to identify the engine and the parts.
The engines must be provided with their original serial number. No modification, improvement, polishing, addition or removal of material of any engine part is allowed. Each engine internal or external part has to be installed in its original position and functioning according to the original design specs.
The tolerances reported on homologation form are necessary to comprise all the machining, assembling and settling tolerances. Nevertheless, the Entrant is absolutely not allowed to make any intervention on the engine, even if the characteristic dimensions after his intervention will still be within the prescribed tolerances. Any tuning is forbidden: the maximum and minimum allowed values and the volume of the combustion chamber have to be measured according to the CIK Technical Regulations.
In any moment, the technical officials, following a decision of the Stewards, have the right to replace any part, any accessory or even the complete engine.
