Thanks again for the posts guys. Anyone know about the difference between net and gross horsepower and where it's measured? Also, what figure, gross or net, is represented by manufacturers when they list the specs?
Could you elaborate on what exactly "wave timing during overlap period" is? How do "positive pressure waves" affect HP/torque in terms of net forces on the piston? It seems that if it were to affect the HP/torque, it would have to be creating a force on the pistons. If you...
Well, I haven't actually measured the back pressure but can induce it's a higher or lower based on certain situations. For example, when there is an exhaust leak or a car is run straight off the header there seems to be a noticable decrease in low end torque. Conversely, if the exhaust is...
First let me say that I'm not a professional. I'm more of a hobbiest, but that wasn't on the list when I signed up, so you'll have to excuse my lack of knowledge.
1) My first question is how horespower (and torque) are measured, exactly. I don't know exactly how a dyno works, but to calculate...
