Re: Dump valve

We have Blitz Supersound dump valves and they're pretty loud. Don't think there is any difference.

Re: Dump valve

I think it fits all new age models but you should phone to check.

This is the link for the ones we have:

BLITZ

There is a sound file on this page so you can hear it.

strictly speaking no, but, VTA can affect the MAF sensor, although I'm sure someone can confirm if its a common problem on imprezas. All it would do would run rich, thats why you get the pops and bangs from the exhaust.

Re: Dump valve

VTA BOV will not use more fuel unless your planting the throttle n backing off..
to my knowledge a VTA won't affect the maf..

Re: Dump valve

yea, I was saying that it doesn't use more fuel but can affect the MAF, just think my post was a bit confusing
