Are we currently in a situation where it is easier to run illegal cars than it has been in the past? With the advent of technology to rallying is it easier than ever for people to bend the rules? I remember in the past it was common practice to ‘strip’ engines at post event scrutiny and measure for capacity/ cam profiles etc. This does not seem to be carried out as frequently anymore (or a least I haven’t heard of it) I know dump valves have always been an obvious choice to tamper with, but how can we know engine internals have not also been changed. I have been a spectator on many events and there is a visible difference between the power output of supposedly similar cars (group N in particular). I am not well versed in what exactly can be done but having talked to people in the know they are saying that illegal cars are commonplace. They have also suggested that some scrutineers are not up to speed with the latest technology and this is very understandable as they are not motorsport engineers. Is there an onus/legal obligation on scrutineers/governing bodies to reimburse competitors who have had there engines stripped and found to be compliant within the rules and if so is this one of the reasons why more checks aren’t carried? Can anyone fill me in on what exactly is the rule at the moment?
