The experts recommend covering 50-75% of the panels and focus on the large flat surfaces. Areas that have a swage or return in them will be mechanically more ridged so less likely to resonate. I worked my way around the doors knocking the panels to hear what had the most sound transmission and...
Completed the passenger door this morning, using the exact same materials and method.
Then on my way to work, I re run the same test.
Same app, same road, cruise on at 50mph. It sure doesn't look pretty but it makes a bloody big difference inside the car. Id loved to have been able to do the...
Made a start on the doors today. The first time these doorcards have ever been taken off, they were super tight and were pretty grubby behind. Fully lined with Dodo 1.8mm Hex, then lined with Dodo Superliner. I double foam lined behind the speaker area.
Interior skin was particularly buzzy so...
The bass trap tile is layer 3 in that location anyway with the super liner directly under it. So I don’t see how it can form condensation in there as it would need moisture and a heat source. I’ve only ever seen a few drips ever find their way in from the rubbing strip fixing holes. It’s all...
Big £££ for a 240bhp motor and supporting mods though and a fragile F4R at that level. Oncost of rebuilds wouldn't be cheap either, not to mention being a pain in the arse.
I totally get why someone would want to keep it Renault, but given the amount of work already required, a K20 will be...
It shouldn’t do as it’s designed for it. Having said that, I purposely kept it above the rubbing strip of the body so no water will be getting on it. I don’t see how it can condensate in there either.
But i will check periodically to be sure.
So far I've done the rear of the car, tailgate, floor and arches inner and outer tubs and rear qtr panels.
2x sheets Stinger roadblock 0.6kg
22x sheets DodoMat Hex = 6kg
1x 6m roll DodoMat Superliner 1kg
10x 300x300 bass trap tiles 0.7kg
Total weigh added 8.3kg
Now i know this test is totally...
I think that’s probably a good shout. I’ve seen massive condensation inside stripped out cars that have been left outside in the rain etc. But having the car better insulated should reduce the level of temperature change inside the car so should actually reduce the chances of condensation...
Finished up the rear foam today. Took it as far forward as the rear bench. Fixed in the foam bass traps with some spray adhesive. I’ve kept these over the wheel arches and above the rubbing strips. Added further deadening to the rear doorcards and took the opportunity to swap the OEM rear...
All drains are clear as is their routing. Not sure how condensation can form on there unless you introduce moisture?
This is the exact same process and materials used to turn vans into sleepers.
I have done the same as you last year and I've been getting a lot of condensation inside the car when it's really cold..make sure you have left a gap between the inner arches and the panel for the condensation to rundown the drain holes.I placed the silver mats and foam just below the windows...
This is why many people get mixed results with sound deadening mass sheets. By fitting the mass loaded sheet, they have stopped a lot of the vibrations and rattles. But without something to stop diffuse the sound still coming through from outside, the road noise will still be quite apparent...
Steve.
I’m also no audio engineer but speaking to a lot of my NVH teams at work and reading as much as I can. The way I understand it, sound is created by vibrations in the air. The panels in the car vibrate and reflect sound into and around the car. The deadening adds mass to the panels to...
Finished off the back of the car with panel deadening and made a start on the super liner. Quite therapeutic once you get into it but it’s not easy to work with as the adhesive is so sticky, you can’t dare catch it on anything else it tears.
