BTCC engine testing under way

A comprehensive British Touring Car Championship engine ‘flow-test programme’, that will result in establishing each turbo engine’s baseline boost pressure for next season, is currently being conducted independently by Lotus Engineering utilising its extensive resources and expertise.

The work is being processed through the championship’s Engine Technical Review Panel – every engine builder involved in the Dunlop-backed BTCC is an active member of the ETRP. The panel is headed by independent Chairman, Clive Dopson, an internationally renowned automotive engine/powertrain consultant.

BTCC series director Alan Gow commented: “The purpose of this programme is not to make every race engine perform in exactly the same way – it’s only right that the best engineering, the best design, the best teams and, of course, the best drivers still see their efforts related to their on-track performances.

“No, the test programme is simply to reduce any wide performance variances resulting from significant differences in the fundamental port/valve designs of the original production engines. It will identify and quantify those that produce superior airflow through the cylinder head and those that don’t, in order that their baseline turbo boost pressure is set accordingly.

“Thereafter, during the course of the season, a strict mathematic calculation – based on a rolling average of each model’s qualifying and lap times over a set number of events – will determine if any further changes should be made to their respective boost levels.

“This will have the virtue of being an entirely clear, definitive procedure which utilises a set calculation and methodology to adjust any significant performance imbalances, based on the qualifying/race lap times achieved by each model. Over the next few weeks we will, of course, be defining the parameters more precisely, once we have validated all the data.

“The important thing is that our teams have unanimously agreed to both the process of the flow-testing and to the introduction of the boost-adjustment calculation method during the season, as they all very much recognise the huge positive benefits it will have for everyone.”
