body and interior How Loud Is Your Car At 70Mph?

[Stu]

OK, 84 dB at 65 mph.  Weber 38/38 with stock air cleaner, IE shorty header and exhaust, 5 speed, 3.90 LSD, new Esty carpet kit, no insulation in floor or doors.  Car Toys installed dynamat, I believe, behind the rear seat when installing my stereo.  I have new door seals, and new window wing seals, yet to be installed, which should lower the noise a bit more.

I used to drive mine with the windows down, stereo blasting, and earplugs firmly fitted in my ears....

[Dev02]

32/36 with synch, headers, ansa, 3.91, new rubber bushings, inside is pretty beat up and the door seals are horrible...

 

with the iPhone app I peaked at 98 @ 70mph... but just sitting in the car with the engine off it reads 70dbl so I'm not sure I believe it.

I think I will borrow my gf's phone and app it.

 

Right now I have partial carpet, back seat removed with boards, rear sun deck speakers (not my idea)  and Ansa .  That probably is going to raise the db.  But honestly I have not thought about it.  I probably should turn down the jimi Hendrix, Voodoo Child (extended version) and cut back on the Stevie Ray.  The Pride and Joy with Albert King ain't helping.  I'm going to do the pre and post music sound test.

 

I'll get back with results.

I don't know, but what I can tell you is that it is absolutely deafening at 105 mph with the windows down.

I just downloaded the sound app on my Droid so I'm going to check my beast at 70mph.

I just tested mine. 5 spd with 3.64. 88db @ 70 in 4th. 85db in 5th. Thanks for the inspiration. Usually drive my 02 on weekends only.

Well on my way home I got up to 70mph, mine is a 4 speed, twin 45 Dellortos, Crane ignition, 292 cam, port matched head , IE stepped header & 2 glasspac mufflers, 101 Db. I knew it was pretty loud when I hit the go pedal , now I know how loud.  I moved over for a Paramedic & that was 101 Db for his siren as he went past me ! Great test & thanks for the inspiration. My Droid sits upright on my dash next to the gauge pod in a little stand made from a wrench set holder from HomeDepot.

around 100dB - 45 Webers 300° BMW Cam, Turbo exhaust

 

I'm never without earplugs when i'm driving longer than a few minutes. I have some specially made for me.

Your could argue now if it's still fun if you're constantly having to wear ear protection -  i'm having fun

 

Oh and my dog looks a bit silly with these on: http://www.safeandsoundpets.com/index.html

I think it should be mentioned that the iPhone decibel meters are not very good. Mine reads over 90dB when i'm simply talking at a normal tone in  a quite room 3 feet away from the phone. earplugs are a good idea... I use them while working, maybe I should just keep them in full time
