Thread: Dyno Science: "CAI" Box vs Open Cone Intake

I don't need dyno sheets to tell me what the ~30 degree change in my IAT's (vs stock airbox/stock IAT) already show. and that ~30* is cruise IAT, not in town. every 10* is said to be ~1-2hp depending on other conditions and timing tables. if the 2 intakes flow enough for the given level of mods (on a NA car) the colder one will produce more power at the same AFR. period.

Now if my AFR has changed (and i bet it has) that is another variable. my STFT and LTFT are pretty close to 0 however (within 2% usually at WOT) so i'll assume the car has already learned any applicable adjustments.

This looks an awful lot like speculation and nothing like evidence. Pretty much the exact opposite of the point of this business.
