Thank you very much for that Ninka.

Yep mildman, that's what I was curious about. The idea makes perfect sense to me, but I can't find any information on it..only my hazy recollection of the MOTOR article. I'm glad someone else thinks they have seen it. Ninka, would you be able to find the article and post it here? That would be a massive help.

I was having a chat to a mate the other day about how much a hot ambient temperature can affect a cars performace, particularly turbo cars. I ended up thinking of an article I read in MOTOR magazine a year or so ago, in which I am sure someone wrote an article explaining that the XR6 turbo actually increases boost pressure in hot ambient temperatures to maintain consistant performance. Obviously, cooler air is great because it's denser, but hot air is a problem because at the same boost levels you are forcing in less air than usual. I can't find any mention of this anywhere, so I'm beginning to think that I am crazy, but I was wondering if some knowledgeable person could tell me if I remember correctly or if I'm pulling something out of my imagination.
