CAI Throwdown

Very weird in the fact you gained that much TQ and not an "ounce" of HP, since HP is a function of TQ. Any change in TQ should result in an influx of HP unless the distance or time over wishing the work is done is changed.

Thanks for the link! A perfect addition!

You also have to consider the weather conditions. I very well may have gained HP. It was a cold day on the stock dyno so much denser air. The 2nd dyno I had was significantly warmer outside so that very well might account for the HP number to "stay the same" when in fact it probably went up. I think my stock numbers might look a bit embellished due to the cool air. There are soooo many factors that affect dyno numbers it's almost impossible to get a 100% accurate reading. The only real way to do true testing is with the same dyno, the same weather conditions, the same car, and the only changing factor be the intake. Even then not every car will respond the same.

to add more fuel to the fire, I have seen weather in the morning 50* and after install and lunch (the fat kids got to eat) 72*. Same day comparison can also be a little off as well

That is why with the test I did it was the same day, temp, car, dyno, and the time took about an hour. There was also no fan on the car at the time and the door was closed to the dyno area.

This is true, and also why I don't put much trust in STD numbers, because they tend to not be as comparable when it comes to different atmospheric conditions during different dyno sessions. SAE is better for comparison purposes when it comes to trying to "disregard" weather changes.

Track numbers > dyno numbers!

[Kosovobandit]

Track result are just as subjective as dyno results. Things like: Temp, track prep, tire, driver, shift points, ect all come into play.

Our auto 5.0 car ran faster at the track with a stock airbox, cold dense air makes for harder hit out of the hole. However my 5.0l tvs kits all come with JLT intakes...more flow more power.

Whoa, when did you get here, Justin? Nice to see you around.
