2009 Build Log for Bumpin Buick

General Restrictions Regarding Sound Damping Materials:

Sound damping materials may be used to reduce vibration when installed in accordance with the manufacturer's recommended installation instructions. In certain dB Drag Racing divisions the maximum amount of damping material that may be used at a given location is limited. (See the Passenger Compartment Restrictions section for each division for specific limitations.) Some examples of these limitations are given below.

Street Division Examples:

A Street Division competitor may use 2 layers of damping material on the inside sheet metal of his roof. However, the competitor may not use 2 layers of damping material on his roof and another 2 layers on the backside of his fiberboard headliner because this would result in a total of 4 layers of damping material in this location.

A Street Division competitor may use 1 layer of damping material on the inside sheet metal of his door and another layer of damping material on the backside of his door panel because 2 layers of damping material are allowed at any given location. On the other hand, the competitor may not use 2 layers of damping material on the inside sheet metal of the door and another 2 layers of damping material on the backside of the door panel because this would result in a total of 4 layers in the door location which is prohibited.

Thanks guess I over looked it a few times, oh well box is too tall for street classes anyways, at least for now, maybe on the real build I will take a sheet of raamatt off and keep it below windowline

good. i mean with all that power etc. and having the frame probably right under the battery.
Yeah it was a temp from my last setup that was a simple T10001bd and the amp was grounded in back as well with the batteries back their all on 4/0. Just moved the 4/0 up the front frame now thats all.

 
looks good.
hey Matt. what classes will sleepy and me fall in?
You guys will both me in super street 1-2 along, it will be a huge class this year

THE SEXY BUT PHAT and UGLY one:laugh:
You will be in the same class with them

If your running SM or SS you can only have 2 layers or 4mm past the b pillar behind that you can have as many as you want;)
What if its under 4mm but still 3 layers?

WHy isnt this in the build log section?
Good question, I wasnt thinking i guess.

 
3 layers is illegal for db drag //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif (unless your in SS or SM and its behind the B pillar)
A total of 2 layers with a max thickness of 4mm is all you can use.
You can have 1 layer that's 4 mm thick or 2 layers that is 4mm thick combined or less, but not 3 layers altogether in one area (except in the mentioned areas)

 
wait let me get this right so anything behind the b-pillar is fine? If so then Im good cause I only got a layer on the doors and nothing above it everything that is three layers is behind the b-pillar

If you have like 3 layers or more then 4mm of deadening (excessive deadening) above the window line but behind the B pillar you can only run SM, SS, or Extreme.

You can run SS NW if the excessive deadening is under the window line and behind the B pillar

You can run street classes if the excessive deadening is in the hatch area where your box, etc, is located and no where else.

Bass Race is, I believe, anything goes for the most part.

 
Well as of right now I only have the back (hatch area) deadened, havent done the doors yet or the front area but I have the deadener for it, so would that allow me to be in Street C if I were to build for that
