Big J Posted February 13, 2009 Report Posted February 13, 2009 Sometimes in competion I see people fan there doors open and close. Doe that really help you gain a db or two? I was told it helps relase pressure in your car that builds up. True or fale? Quote 2 DD 9515 1 Soundown SAZ-3000D 2 Optima Redtops Big 3 upgrade Hitting 151.1db

Derrick824 Posted February 13, 2009 Report Posted February 13, 2009 In certain events or classes opening the doors is allowed and yes it's typically louder with the door open. There are some vehicles that do not gain though. As for fanning the door, I personally haven't seen a difference from just leaving it open. Quote
dtbrown Posted February 18, 2009 Report Posted February 18, 2009 Every car is different. Some gain some don't by having door open. Quote
Team Nemesis-DJ Posted February 18, 2009 Report Posted February 18, 2009 Every car is different. Some gain some don't by having door open. X2 on this a few of our cars gain 2.5 -3.0 mine only gains tenths ... Quote
Guest Powered By Hate Posted February 18, 2009 Report Posted February 18, 2009 REALLY loud cars.. the doors are so damn heavy the doors cant be fanned.. they wont hold up their own weight without a jack. I see outlaw street cars do it too.. i really dont see how more pressure can fit into the cab if you fan and shut the door. Quote
Bills Posted February 18, 2009 Report Posted February 18, 2009 well, my understanding of it is that if your box is not tunned high enough, opening the door or fanning will gain you, but if your box is tunned highenough, it won't make a diff. so if your tuned in the low thirties, faning will pry help. but if your in the 40's or so, it may not help. but thats my understanding on it Bills Quote KwB Team DC Audio Midwest captain
Derrick824 Posted February 18, 2009 Report Posted February 18, 2009 banginAltima's box is tuned to 33hz and opening/fanning his door doesn't gain anything. Not even a tenth. Slamming the hell out of it is good for at least 0.3db though. Quote
