Proceed With Caution

Csptrack1_2

Have you ever had that feeling that you were forgetting something? That thought at the edge of your mind that you just can’t seem to bring into focus?

Well, I had two realizations recently.

First, Sema is right around the corner.

Second, that means that I am really behind on updating the progress of our Project Car.

Up to this point, what we have done is basically make the most of what Subaru gave us to begin with. Subaru does lots of research and testing before releasing their cars for us to buy. What we have done is to tweak the car a little here and there to realize overall better performance. We have definitely improved things a lot, however, if we want to go further, that means that we are going to have to cast away many of the key stock components and replace them with something else.

So since we are going to be making some big changes, we need to make sure that we do our homework so that we can actually improve upon what Subaru gave us, rather than make things worse. Basically, we need to proceed with caution.

What is the difference between Horsepower and Torque?

If you are thinking about improving your car’s performance by bolting on anything from an intake and exhaust to fully rebuilding your engine with different cam’s or pistons, it is very helpful to understand the relationship between torque and horsepower. The trouble with talking about the difference between the two is that there isn’t that much of a difference really.

In an internal combustion engine, when you ignite your air/fuel mixture, this causes the gas trapped in the cylinder to expand rapidly, and push the piston down. The piston is connected to the rod, which is connected to the crank, and as the piston is pushed down, that forced is translated to the crank. The twisting force exerted on the crank is also referred to as torque. Or, to simplify things, Torque is the amount of force the piston is pushing down with.

So what is Horsepower? Horsepower is a measure of the amount of Work the engine does over a given Time.

The basic definition of Work is:

Work = Force x Distance

Therefor: Horsepower = Force x Distance
                                         Time

But what we are talking about here is the relationship between Horsepower and Torque. Torque is basically the force that we are talking about in the above equation.
