Bringing up this thread again due to a recent Autosport podcast, which can be found here
https://www.autosport.com/podcast, entitled "Tim Harvey and the golden era of Super Touring"
In it, he talks about the Peugeot campaign, well worth a listen. Below are some bits:
Q: Peugeot was struggling with a different engine spec at times, didn't they, to what they were using in Europe very successfully.
TH: Yeh, that was the biggest waste of money and everyone's time and effort really, because MSD built the cars in the UK with absolutely no collaboration what-so-ever with Peugeot Sport in France who were building the cars for the German touring car championship [STW], which Aïello was winning in. We had absolutely no crossover of technical information, engines.
Q: Defeats the object of super-touring really, doesn't it, the point was it was the same spec?
TH: It was, exactly the same rules, but Peugeot France would not share anything with Peugeot UK and you just think for a manufacturer to have produced, what at the time was arguably the best car in Germany, not to share that out of Anglo-France bad relations seems absolutely bizarre.
It was three years of good, hard racing. It was fun with Patrick and good with Paul Radisich. We did the best we could with the budget. Our total bill was less than the French spent on engines.
