Re: Net Horsepower vs. Gross Horsepower (SuperFast80)
What really counts is the HP at the rear wheels. The new cars have around 8% to 12% loss in the drive system and our old rotten Vettes have at least 20% loss in the drive system. Rear wheel HP wins races the rest of the stats are worthless

The formulas are all well and good but engines from different era's had different draws on them. For a 1960 engine there would not be any emission equipment to factor in, for a 1978 engine there would be a huge draw for emission that would have to be factored in, and then for a 1999 engine there would be emission equipment but their draw would be much less so their factor would be less. In other words, one formula will not fit all years or all applications.

405hp added headers, cam cold air induction, hurst shifter...My car dynoed at 482 hp/462 torque. Any idea what flywheel hp would be? The Vette guys told me 10 to 15% higher.
