A guy who just done some work on my car was saying that if I drilled about 20 hopes in the bottom of my air filter box I should here a better noise like what my dv should be making.
Is this ok to do and any advice would be appreciated ?
-
Yea lot people have done this. Smooth out the inside of the airbox too and gt a pipercross panel filter :wink:
Have search around tons of posts on it and few how tos flying about
-
Hmmm, from what I've seen on the net it just seems to make the whole car sound meatier. Rather than the tssshh I'm looking for from gear changes like a dump valve. :undecided:
-
it will make the dv louder too mate. not as loud as a cone filter would make it but almost.
the airbox kind of acts like an exhaust resonator, remove it and you`ll get all the noises from the maf back.
make holes in it and you hear the noises but youre also kind of protected from all the engine heat too.

Should of brought a scooby :lipsrsealed:
It will make dv loader too as jamie said. You need a remap and then with drilled airbox will give slight tshht sound from the valve. Or just stik a cone filter on..get good grunt too :grin:
-
Navmk4gti, you mentioned the drilling of the airbox will make the dv louder. The problem is..... There's no noise atall at the moment
-
you`ve probably got something wrong there dean, it should make a slight "tss" at least..
i think your boost pressure needs investigating.
next step for you, buy a boost guage! and some 3mm hose :smiley:
-
Have u smoothd out airbox first ..have you got a pipercross panel filter?
-
Yes I've got a pipercross panel filter. And no I've not smoothed the box as of yet. My dv is fine and the same thing happens with my mate's dv
-
If you expectin a load tshht ur not going to get it. Its gonna be a slight sound. Itss not going to sound like a dump valve on jap turbos. If you want that noise get a forge split r but they dont work as well as 007 or 008
-
try running it with the cone filter and take it for a blast, put some load on the engine, like from low rev in 3rd and take it up to about 3.5k rpm and let off the throttle fast..
p..s how do you know you havent got any leaks?
-
I don't know 100% mate, but I've checked pipes and they seem to be ok :embarrassed:
-
do the sucky sucky tongue test on the vac pipe to the dv :grin: .. if its leaking, then it won`t pull the piston in the dv.
take the pipe that goes to the dv, suck it, and put your tongue on the end of it, if the suction goes then its leaking..
just a little trick i learned from the toph :laugh:
by the way, i think that pipe i supplied you was 4mm, it might be a little loose for the DV. 3mm is better :wink:
-
Jamie I've got 3mm on there mate, by the way, are you talking about sucking through that 3mm pipe to do the test
-
You need to suck the DV nipple :laugh:

You need to suck the DV nipple :laugh:
i like nipples :lipsrsealed:
