hahah ok ok.. but i onli interested in vacuum.. but too bad now on tight budget.. tmr u guys goin autogen?

cancel liao lo. me also tight now. later la. next time wan go adi. ^^

last month jus went there to buy insuflex to sound proof my car doors.. now still doin.. bought d stuff but no time to do.. haha actually there got alot of ICE stuff.. n quite messy.. u can c alot of UR bars there.. improve n gab stuff there too.. haha

icic. but my 1st thing is install vacuum n volt 1st. to monitor my engine 1st later onli do sound system.

vaccum lo. nid to see how i press my pedal.... save some fuel to buy sound system

oic.. ok ok.. u r the 1st one i heard tat save fuel using meter.. haha good wan.. erm.. if me jus put on k&n drop in.. save fuel more power and most important save money cuz no need change air filter anymore hahaha

err...you should leave the holes in the beams open
those holes are there for ventilation
if water gets in and all is closed (and it will get in...thats y the whole car can drain...all the beams...under the car...the channels forming the door sill...in the bonnet...even the doors have drainage holes....), water vapor will be trapped inside n cant dry out that fast
and as im sure u all know...water n iron dont exactly make a good team
the engine will most prolly be more silent compared to using the triangular pieces
but then the life of the metal will be compromised

and btw...its not sound waves we are trying to stop from getting out when we install this sound insulation as we call it
it is actually damping material
we are basically trying to dampen the vibration of the metal surface in question
not stop sound waves from penetrating it (which is impossible as the metal is a solid and sound waves are merely vibrating air particles)

wah sifoo's advice

and as we were talking about water in the bonnet justnow...doors were also mentioned
if you are not aware of just how much water comes into the door during a heavy rain,...try taking off the plastic shell door cover and leave the plastic sheet on...
then get sum1 to hose the window down at full flow
(this is only a fraction of what nature can throw at your car mind you)
and then see how much water actually flows through your door

insuflex is a rubber material (granted it is synthetic)
and i am also aware that it is a closed cell system (meaning its not a sponge)
but try dipping it in water for a few minutes then take it out
all of the surface cells (which are open on the surface) will be holding water
also, when you stick it to your door,...the inside is going to be oily as there is antirust grease which they have sprayed on the inside of the door
yes, i know it can be cleaned off
but it will never be 100% oil free unless you use petrol (which you should never do as it will damage the paint...)
so the glue u are using to glue the insuflex into place will leave cavities here n there...
i understand that you will try your very best to get it to stick all over
but it can never be a 100% job
these cavities will in turn retain water when it rains and draining will be much slower
and as mentioned above, water n metal dont make good friends
also, the insuflex will accumulate ALOT of dirt over time as the surface is not smooth
presence of dirt also accelerates the degradation of metal very significantly

that is why tar sheets are always used when it comes to areas that are exposed to water
tar is a petroleum based material and thus will not be adversely affected in any significant way by the oil film left by the antirust coating which you have cleaned off

therefore, i strongly advise against the use of insuflex/superlon to insulate inside the door cavity

i stick insuflex on the door panel instead on the door.. so far ok.. everythg works fine..

this one will shock u even more...



sifoo really sifoo...

hmm...k&n need to oil again after wash rite?
the only way that a filter can increase efficiency is by reducing the resistance to the airflow of the intake manifold
this in turn would mean either a thinner membrane, or bigger holes in the filter membrane
either way, the bottom line is the same...more dust particles get into the engine

these kind of filters evolved from racing and rally cars
i do admit that they improve performance
but as the saying goes....theres no such thing as a free lunch
there is always a compromise somewhere

in this case, its in the life of the engine
more particulate entering into the combustion chamber wears out parts faster (think sand paper)

the vac gauge does not influence the operation of the engine's system in any way therefore it will last as long as it can as long as it is properly taken care of
you can monitor how much you press and thus make sure that you are not merely dumping unburnt hydrocarbons into the atmosphere
this is especially important for underpowered cars like the iswara lmst as it is easy to overpress when it comes to underpowered cars

Added on November 3, 2007, 12:43 amerr...arent we then not addressing the real problem at hand?
the doors sound 'tinny' (like milo tin) coz the outer door panel vibrates and has no damping on it
that is the main source of the sound from the doors
even if you insulate the plastic panel inside, the metal outer panel is still vibrating
this vibration transfers to the rest of the car body through the door links and will thus increase the overall cabin noise

its better to try and stop the problem at the source...not just cover it up

ok ok.. u have ur way of thinkin.. i start wit the door panel 1st den onli go to the door body.. thx sifoo for advice..
me noob
