Im 5'4 and I want to get prom shoes that have a 4 3/4 inch heel (no platform). My prom date is 5'8. How tall will the shoes make me because I'm super scared to purchase them and end up being taller him! [Editor Rob: if they don't have much platform then you won't really get that much over 3 inches.Editor Rob: you can easily buy a platform heel (if they are advertised in the shop as 5.5 or 6 inch) and still be shorter than him, they might give you 4-4.5 inches but of course your date would likely be standing 6ft 2 in his shoes, and you at most 6ft 0.5, so still a bit shorter.
Brake horsepower (bhp) is the measure of an engine's horsepower before the loss in power caused by the gearbox, alternator, differential, water pump, and other auxiliary components such as power steering pump, muffled exhaust system, etc.
Engines make a lot of power that never gets to the drive wheels. Your cooling and heating systems, your water pump, your alternator all consume power. The BHP tells you what is delivered to your drive wheels. Your BHP will be far higher than the power you can actually put on the road surface. Even on the old monster cars the power delivered to the road was limited to about 40hp due to the nature of tires and the road service and that was for the big V8 engines.
