Just checked out the specs on the Euro Chevy web site, they list the Chevy Corvette with power rating of 344hp@5,200rpm and 483lb of torque @ 4,200rpm. The U.S spec Chevy web site list the power rating of 350hp@5,200 and 375lb of torque @ 4400rpm(mt) and 360lb of torque @ 4000rpm(auto).
Why such a huge diff in torque rating?
this is what they print
Re-invention of the legendary small block
Living up the "small block" legacy is an enormous responsibility. No other sports-car engine is so well-known as the Corvette V8. And its guiding philosophy - simplicity, lightness of weight, and elegance of design - endures in the Generation III V8, the LS1. In designing this engine, one thing was certain: it had to be the best balance of everything. A tall order, and one that results in the most exciting V8 to ever sit under a Corvette hood.
Its specifications include an all-aluminum block, a unique camshaft design, a 10:1 compression ratio, a lightweight composite intake manifold, and a highly sophisticated level of sequential fuel injection technology.
In the best Corvette tradition, LS1 numbers speak for themselves:
Displacement: 5.7 liters
Horsepower: 344 at 5,400 rpm
Torque: 483 at 4,200 rpm
There are several systems in use in europe. DIN [Dueche Industries Normen == germany HP] is one such system. BSI [British Standards Institute]. These systems differ than ours by a couple of percent based on what they define as an equivalent pound, and equivalent foot, and an equivalent horse.
Besides, as an avid reader of this forumn (hint, hint) you understand that even equivalent dynos have accumulated errors of around 3% anyway, which is much larger than the HP differency you are currently questioning.
