Experimental Engines

Last Updated: 19/03/2021 20:02

It is important to recognise and understand that the 16v engine is EXPERIMENTAL.  As has been made abundantly clear in the Technical Specs for ORC Stock Rods, the 16v Experimental Engines are under consideration as a cheaper alternative to the existing engines.  There is no wish for the 16v Experimental Engines to be a route to increasing speeds.  The 16v Experimental Engines can only have a future IF they are cheaper than existing engines.


The 16v engine will remain experimental for 2021 and2022.


There must be no machining or balancing of the standard 1400 or 1600 flywheel components.


The use and performance of these engines will be constantly monitored throughout the racing season. The promoters reserve the right, at any time, to introduce a performance control measure such as, but not limited to, the requirement to have a restrictor plate fitted to an engine, or a restriction via the ECU.


A driver wishing to use a 16v Experimental Engine must follow a process:


1/ Apply to the ORC Stock Rods sub-committee for permission to use the engine.

2/ Complete a data sheet, detailing the components and ancillary items the driver intends to use, such as Engine cc, engine code, cylinder head, etc.

3/ That data will be processed and approved or rejected.

4/ Assuming the application is approved, on any such occasion that the 16v Experimental Engine is stripped, it must comply with the information on the data sheet.


Data and information will be collected as the 2021 season progresses.


For Championship events (World, European, British, National, ORC, English, Irish, Scottish), drivers will be permitted to use a 16v engine, but only in conjunction with the following items:


- Control Omex ECU and wiring loom

- Control adapter plate for inlet manifold, to enable the use of a standard 8v manifold and Pierburg carburettor



Further information will follow.
