Citazione:Ah ecco, quello volevo sapere. Va bene solo per gli americani :zsarcastic4xx:
No anche per le europee hehehehe..... Es con Volvo 744 turbo quindi non proprio un animale da dragstrip ...
Net HP = Weight in pounds* (Speed in MPH/228.4)^3
As an example, Car & Driver tested the 744 Turbo in their June 1990 issue. The car weighed 3,081 lb. without the driver.. the 'race weight' was 3,231 lb. The car ran a 15.7 second quarter at 86 mph. Let's plug it in to the formula:
HP = 3231 * (86/228.4)^3
HP = 172 Net
Volvo rated this at 162 Net. We come out a little high. Or does Volvo underrate a little? I'll say this - I've used this formula for years and that's how the 228.4 was honed - actual experience from cars that had actual power curves - and when I use it on Volvos it tends to always come out a few percent higher than the factory rating. This could simply be that Volvo underrates just a little.
