There are a few reasons people talk about. On the classics, there is the theory that the standard bonnet scoop becomes useless after the 100mph mark, so prolonged high speed runs will obviously be a bad idea, resulting in knock.
Then there's the lack of mapping with bolt on mods, again knock being the issue.
There are a few more 'commonly known' reasons, but I can't think of them off the top of my head because it's been a while since I owned a Subaru and had it tuned, therefore I haven't had to think about them recently.
Would have total confidence with a car mapped by the likes of Andy Forrest though, if all the supporting mods were sound. Just my opinion though as I haven't been stung with engine failure.
Yea heard of those theorys, you'd think subaru would hold their cars flat out, long enough to test things like that though it seems a bit of a schoolboy error for such a huge company to make.
unless your connecting det to seized bearings which some people do though, thats besides the point.
As I said before, Until someone can prove why SOME engines seize bearings, I wouldnt buy a subaru....
