Last time I read about a super test on four or five chipped cossie sierra`s they were all pushing 500+ hp and four of them had terminal engine damage before the test was over. I know things have moved on but 1000hp??????

The engine in the 1st link is not a sierra engine.
But I am saying that you can get serious power out of a well built engine, even one with an old design. The Sierra I have linked to is very well know, it even made a Fool of Tiff Nedell and a Twin Turbo Lotus Esprit  Look at a volvo B5xxx or B4xxx series engine and it has a bottom half of the block incorporating all the main bearings so the whole bottom end is one piece and the caps can's shift.. That's a serious improvement to longevity and power handling. Most "untimely" failures on a well built turbo performance engine are down to external failures, someone tweaking the boost or soaring IAT's. TT
