Re: Speed is bad again in WNY (2:45pm)
that 300hp is car is not a 300 hp car for the record. Most car manufactures rate hp and torque on crank ratings rather then factoring in the loss of power though the drive train and axles, wheels.. etc....
300hp on the flywheel sure... but on a rwd car your looking at real world numbers around 245.
don't forget how altitude and octane affects performance.

| Since 1971 engine horsepower is measured in accordance with SAE standard J1349 at the flywheel as stated below:
"Starting in 1971 automakers began to quote power in terms of SAE net horsepower (as defined by standard J1349). This reflected the rated power of the engine in as-installed trim, with all accessories and standard intake and exhaust systems."
This measurement does not take into consideration drive line losses which very depending on transmission type, gearing and other factors. But ALL engines are rated per this standard to insure ratings are consistent and the buyer is getting what he or she is paying for. The FTC has a rating system for audio amplifiers; all manufactures rating's must comply with this measurement criteria. My point is that almost every other industry is regulated by truth in advertising laws; apparently this industry is not yet. If your happy with that fine, I'm not. |
