is it possible to have two dumpvavles for example 1 either side of the ic,
will requirer a 20mm hole etc,
im after the sonud of a atmo dv but want to keep the recirc
cheers for any feed back,

 

does this help?

 

????????????? lost

 

where you put the other pipework??? eg...the one that goes to the manifold ??

 

Only possible situation I can think of needing 2 dump valves, would maybe if it was a twin turbo set-up.

 

I have seen a car with 2 fitted but i couldn't tell you how it was done mate.

 

LMAO.....

 

any1 else

 

It's pretty obvious from Chip's diagram to be honest

 

yes you can fit 2 bov, i had 2 on my old punto gt, and some people on there GTs use to put them both ends of the fmic.

not sure if it was any louder or anything, but it was different then following the norm

 

You don't need two - I had a GFB one which was fully adjustable from full VTA to full recirc so you can get the sound plus recirc benefit

 

this is what i ment its a my99 classic tmic

 

why not just get a dualport dumpvalve? that way it`ll recircup to a certain point and vta after that

 

I have a front mount and use the larger DV of the 97 model, it sounds just the same as VTA but without the problems. Front mounts are fussy about DV,s I tried 4 untill I got the correct one.

All the others made car run crap.
