just to clarify, timing doesnt give you HP at all... lol not sure if you every dyno tuned your car, but its done in two sessions... first you achieve AFR that you want and like, then do the torque with timing !!!
Its actually completely impossible to increase engine torque at a given RPM, without increasing horsepower at the same RPM. See....they are really related...
Torque is simply a momentary angular force - power is energy exerted over time (a rate of performing work).
The relationship between horsepower and torque is expressed as Torque (lb/ft = (HP * RPM)/5252
Therefore, if at a given fixed RPM you increase torque, you must also increase horsepower.
You can of course, alter WHEEL TORQUE by way of altering the gearing (as gear ratios will multiply or divide torque according to their gear ratio, as the rotational speed of the wheels are different compared to the rotational speed of the crank) without increasing horsepower - but timing wont change your gearing!
Timing *will* enhance horsepower - but its not the only enhancer of horsepower. When you boil it all down, every ounce of power your car makes is derived from the burning of fuel (the conversion of energy released during combustion into mechanical energy). Timing alters WHEN the fuel is ignited relative to the position of the crank which can alter how much force is exerted on the pistons. The whole goal of making horsepower is to burn as much fuel as possible while maintaining the AFR in the range where it makes the most horsepower, without blowing the motor to pieces. By freeing up the engines ability to breathe, or by adding a turbo, or by throwing nitrous at it, it allows you to burn MORE fuel at the right ratio and thus make more power.
While i'm at it - i'll clarify a post earlier regarding compression and turbos. A turbo charger *does not* increase compression. Compression is static (valve overlap not withstanding) - a 10:1 compression piston will compress the air and fuel in the cylinder 10 times. In the NA game, that means compressing from 1 atmosphere, to 10 atmospheres. If you have a turbo pushing in air at 2 atmospheres (psia of around about 28psi, or a psig, the pressure read on the gauge, of 14psi), then a 10:1 compression piston will compress it to 20 atmospheres. Cylinder pressures go up, but the compression ratio is going to be the same.
I've had it up to my neck with the miss information, and downright rude and obnoxious posting in this thread. Along with the incessant postwhoring. If you want to have a conversation 1 line at a time, PLEASE use PMs. If you want to post incorrect information, don't give me attitude when you are corrected.
I'm seriously 1 stupid post short of pruning this thread back to the (few) worthwhile posts in it, and locking it.
