[QUOTE="Bumpin' Yota, post: 477614, member: 547455"] Well ther are several ways to skin this cat. If I were in your shoes, and it was a dB drag event, id start out with a sine wave at 40hz moving up to 60hz for qualifying. (Keeping track of about when your car gets loudest.) Then as soon as you can, pay for several reruns. (Inform the show promotor that you need to find your loudest note for these reruns - also keep in mind that the show promoter does NOT have to allow reruns after you qualify so in a multipointer it's unlikely you'll get reruns...) Ideally you'd try to find your note while burping full tilt, but you do not have that luxury of time at an event. Therefore you will need to turn the system down about 20% from max and burp at each note starting at about 40hz and going up in frequency. Note what the score does. When the score stops climbing with each change of note you have a good idea of where your loudest note is. Full power burping may or may not change this note, so in your elimination rounds you need to try refind the loudest note. 1. Right when the judges say "GO!" nail the system at the loudest low volume frequency for about 4 seconds straight. 2. [B]Note the score.[/B] You'd be surprised how many times I've forgotten to do this - when in the lanes, there is a LOT of adrenaline. 3. Then, after you've noted the score, move down one frequency and make no other changes. 4. With about 5 seconds left, nail it again and see if the score changed. If there was no change, the next time you run try one frequency higher than your loudest low power burp frequency. If neither differing frequency improves your score you've found your loudest note. If your score went up at all with either differing frequency, continue in that direction until your score stops climbing. Once you have found your loudest note, THEN you can try changing other things like moving your seats, visors, center console, holding various panels etc. [B]but DO NOT make any more than 1 change at any one time!!![/B] That way you know what each change does for your loudest volume.
