Acoustic valve induction

[craigy2703]

With my homemade ktec style kit I'm going to be fitting can I just take the air feed off the caustic valve and leave it there don't really want to go to all the effort of removing it if I can just leave it sitting there with no ill effect thanks

 

[hipwell]

Yeah just leave it there if you want.

Its all about weight reduction though..lol

 

[DaveDreads]

It's what I did, cut the hoses off and left it in place.

 

[MrBlonde]

What does that actually do?,whats the benifit from doing this?

 

[marinemackay2003]

Its a small pre-induction valve, controlled by a vac pressure in the inlet manifold, that supposedly helps cut induction noise at higher rpm. Is apparently there for EU noise level build regs.

most remove it, to facilitate bigger air feeds to the filters

if you remove it make sure to plug the hole on the inlet manifold vac pipe or you will idle at about 2000rpm lo

 

[MrBlonde]

So all it does is make it louder induction noise?

 

[marinemackay2003]

very slight increase when removed

 

[DaveDreads]

So slight you'll wonder why the hell they bothered to fit it in the first place.

 

[MrBlonde]

Yeah im not gonna bother

 

[DaveDreads]

If you're using the standard airbox there's not much point,
if you want a K-Tec style IK or V6 airbox then it's worth doing,
although saying that i'm using a V6 box and all i've done is remove the hoses,
the actual valve is still in place.

 

[MrBlonde]

Yeah i have a k-tex style set up with a pipercross filter,yeah i wouldnt remove the whole unit just block off the pipes etc.So whys it worth only doing it if you have a induction filter set up then?

 

[DaveDreads]

I gets it out the way so more air can get at the filter.

 

[MrBlonde]

Yeah but cant help that much only going to give it tiny bit more & its only for road use the car
