As long as I have been around cars, the ONLY method of determining the power output of an engine, is a dyno. What else are you using to determine power levels?

The track is a good way to but to a point.

How will a track tell you how much power an engine generates?

He is using the tried and true way of measuring performance by using track data. Datalogging, ET's, MPH, 0-60, shifts, temps, etc.
WBT is correct in saying that dyno results mean very little. How the car performs in it's intended envoirment is really the only proper way to determine accurate results.
Some of us old folk were doing this long before the use of dynos were the norm. I use to tune my blower cars the old fashion way with a timing light, reading plugs, fuel pressure and checking tire prints. We had no idea (nor did we care) what the car made at the tires. It was how the car performed.
Now that dynos are everywhere and technology is common place that most people don't know how to work on their cars anymore without a programmer in their hands that the dyno numbers have become more about bragging rights or measuring how a car "should" run.
It happens all the time a car makes great power on the dyno and doesn't run like it should according to what one thinks it should. Same goes for the other way, some cars dyno like ass but run like a scalded ape on the street.
It all comes down to a solid tune, a proper set up and a driver who knows how to optimize all of it to take advantage of it.

What about measuring horsepower and torque(which is what this thread is about)?

It does to an extent. If you have ever been to ffw you will see everyone of the guys running fast cars with their lab tops out after every race adjusting crap. The dyno is generally a base line but for true tuning you need to data log on the street or track and adjust from there. That's where you will get your best tune for all around performance.

Yes, the original topic was comparing the two intakes to see which performed better. Where it went astray is difference of opinions of different driving/racing preferences.
You mentioned dynos. Dynos are merely a tool to get a car tuned. But guys like WBT are constantly tinkering with their own tunes to optimize the set up for the track. Where the dyno subject loses focus is where people use the dyno as a measuring stick for performance. Peak numbers mean SQUAT.
Dyno numbers can be manipulated in many ways on a dyno be it settings, load or whatever else have you. A number of other things can effect it as well, weather, trans type, gearing, convertors and so on.
Just because car A makes more power than car B, doesn't mean its faster. There are other factors involved, suspension, weight, driving style, auto vs manual and so on. There is FAR more to it all than just peak dyno numbers.

This is post #7 on the first page.

It's a moot point really. You can dial in a car's system for a particular track and use the same setup and be less effective at another track. All things being equal, tires, LCAs, gearing, shocks, transmission, cage, harness etc, would you prefer to have more or less power than you have now?

Yup.
