Regulations can be a minefield, and for those involved in setting them, it must be a nightmare.
Some are related to safety. Some are designed to reduce costs. Some are designed to try to equalise performance between different cars and engines which offer very different levels of performance.
Safety related items: Modern Motorsport is now a very safe sport, all things considered. Yes, there are accidents, and people do get hurt, but thanks to prompt action by circuit Marshals and Medical Staff, but also that each car has been checked by the Scruitineers.
At the start of every race weekend, each car is checked by the team of MSA Scruitineers. These people are looking for safety critical items – a car that is mechanically fit to race, with working rain lights, fully operational fire extinguisher systems and electrical cut-off systems which kill electrical power and to reduce the possibility of sparks. Harnesses are checked for integrity and to make sure they are still within date. Helmets and race suits are checked at the same time to make sure they conform to the required standards. Periodic adjustments and improvements to regulations are issued from time to time – recently one manufacturer of safety clothing had their license suspended, and also a clarification on roll cages was issued.
After a race, cars are subject to further scruitineering, usually to make sure that they comply with series regulations – complying with weight limits, ride heights, wing heights, airbox volume, fuel sampling et cetera.
Many people have no qualms with these regulations, some set by the MSA, others by their chosen race series. Sometimes those caught out, especially in club motorsport, and they haven’t won, are given a slap on the wrist and told to make sure it complies next time, but sometimes the scruitineers are more strict and will exclude drivers whose cars are technically illegal.
Cost related items: Motorsport is an expensive sport, and sometimes it is necessary to limit spending by introducing regulations which control the levels of expenditure in certain areas – the danger is that whoever has the biggest chequebook wins. Introducing control tyres, limiting the number of fresh sets of tyres per race weekend, control fuel and specifically prohibiting certain modifications are all measures which can be used to limit expenditure. Some of these fall into the equalisation type of regulation – by making everyone run with the same tyres or the same fuel, this tends to equalise performance to a greater or lesser extent.
Performance Parity: This is the hot potato, and currently in BTCC there is a huge storm brewing between the turbocharged NGTC cars and the older S2000 cars. The series is currently in transition between the old regulations and the new regulations. The main problem is that the series director and administrator, Alan Gow, publically said several times that there will be an overall level of parity for both this year and next, to ensure an even changeover and to ensure that the older cars do not become outmoded and devalued overnight. The problem is exactly how do you give parity to two different breeds of engine?
As shown so far in the 2011 BTCC championship, in terms of ultimate performance, the turbo cars have had the edge, and the first adjustment to their performance came after the Donington round, where each car was given a 0.1 bar reduction in boost pressure from the peak boost levels logged at Donington by the mandatory data logger systems. The pace setting Hondas of Team Dynamics were pegged back a further 0.1 bar, a backhanded compliment for engine developers Neil Brown Engineering who have done too good a job building an engine complying with the regulations. Still not enough, as the turbo cars were once again the quickest cars over a flying lap at Thruxton and through the speed traps.
Organisers TOCA have several weapons in their arsenal to adjust performance. Reducing boost level will help to reduce the acceleration advantage. Reducing inlet restrictor will reduce the engines efficiency particularly at higher RPMs, and maybe cars could be reduced further by an electronic rev limit. That is before any adjustments are made about the weight limits and levels of ballast each car runs with.
Last year, the LPG fuelled, turbocharged Team AON Ford Focus has its peak boost level reduced several times during the season, and the restrictor size reduced in diameter as well. These measures just affected a 2 car team, and yes, those cars were quick in a straight line, but these cars didn’t dominate the series as much as many feared. The bigger problem is that just over half the field have switched to an NGTC engine, and the Chevrolet Cruzes of Plato and chums which were the class of the field at the end of last season are now struggling to break into the top 6. Lets not mention the SEAT turbo diesels from a few years ago.
Diesel engines were permitted into the Le Mans 24 hour race, and the other LMS series endurance races, and since the first year that the diesels have raced in the modern era, the leading petrol cars have not been able to compete on a level playing field. Series organisers have tried to limit the power of the diesels, by reducing boost and restrictor sizes, but it appears the design engineers are more clever than the engineers who are working as consultants to the race series organisers. This is often shown in Formula One, where there are repeated attempts to curtail speeds, and very soon afterwards the cars are as quick as they were before. I’m sure Audi and Peugeot are delighted and have sold a lot of diesel cars on the back of it, helping make performance diesels more acceptable alternative to what was there before.
As there is likely to be an increase in fuelling options – petrol, diesel, alcohol based fuels and the increasing use of hybrid power – either in terms of batteries, or the increasing use of Kinetic Energy Recovery Systems (KERS) which give performance boosts. How will this be catered for?
The old formula of a turbo being classed as capacity x 1.4 is long gone!
So, faced with all that, who would want to be series regulator?
