Will adding 6-7 layers of Dynamat change your vehicle's peak frequency?

Subject: Re: Quick question for anyone that can answer Fri Feb 06, 2009 7:20 pm

probably so

Subject: Re: Quick question for anyone that can answer Fri Feb 06, 2009 7:22 pm

thought so but wasn't sure never had to add that many layers before

Subject: Re: Quick question for anyone that can answer Fri Feb 06, 2009 7:40 pm

and if it's in the front cab also makes it a super mod car

Subject: Re: Quick question for anyone that can answer Fri Feb 06, 2009 7:47 pm

no i only have it in the back not even on the doors. just to stop the rattles

Subject: Re: Quick question for anyone that can answer Fri Feb 06, 2009 7:50 pm

why would it make it a super mod, we have never had rules around amount of material, as long as factory panels are back on and everything is functionable.!

a copy of the 2009 rules can be viewed from the home page. theres a buttom called 'Rules.'

imagine that

Subject: Re: Quick question for anyone that can answer Sat Feb 07, 2009 6:28 pm

I think the better question is can you fit 7 layers of deadenin under stock panels. I'd be hard pressed to think I can really. 2 or 3 should be good to go

Subject: Re: Quick question for anyone that can answer Sat Feb 07, 2009 6:30 pm

You need to change the box volume as well as the port length if you are targetting a new frequency. How did you test that your car's frequency changed?
