Junior Banger Rules

There have been one or two issues raised at scrutineering, Some of the main problems are highlighted below.....

 

13. ENGINES 

1. The engine must remain as it was produced in its standard form. 

2. The air filter may be removed or replaced. 

3. Only the 34 ICH Weber carburettor may be used to replace the standard carburettor for the 

model of car being raced. 

4. No modification to the carburettor allowed. 

5. Multi point injection can be used, but you may also remove the injection system and replace it 

with the previous carburettor set up or Diesel. 

6. Any alteration or removal of engine numbers will deem the engine illegal. 

 

 

Engine / Gearbox Mounts 

1. Alloy engine/gearbox mounts can be replaced by fabricated steel versions and welded or 

bolted to the chassis. The maximum size of the mount is 5 inches where it is attached to the 

chassis. The mount must not exceed the original size of the standard mount which is being 

replaced, it is solely for holding the engine in and not for strengthening, and no part of the 

mount must be in front of the engine. 

 

 

Bonnet Fixings 

1. Bonnet bolts cannot be used. Bonnets must be secured by seatbelt only with a maximum of 4 

ties. 

Triangular corner plates or straps may be used to secure the rear of the bonnet by bolting or 

welding (1/8”thick). Plates or straps must be placed no further than 12” across or down from 

the back edge and side of the bonnet. In this case you may only use two seatbelt fixings at the 

front.
