need advice on best dump valve for p1(my20).thinking of having dump to atmo version..has anyone tried forge/blitz valve on a my 99/20 and which one is loudest and best performing and yes i know they dont increase power..

 

I would go for a Forge, shimmed with upgraded spring.

This is a recirc jobby, which is best with standard ECU, but does make the car chatter like a WRC car

does the forge one come ready set up with stiffer spring/shims tried one once before atmo and it wasnt dumping

 

I use the Blitz dv. You can change sound (two versions of outlet). Im very satisfied with sound in basic setting. Maybe the price is little bit higher than others.

 

Don't suppose anyone has any sounds of these dumpvalves do they?

Being really sad the sounds important to me After hearing Craig Hardmans HKS one at the bedford track day I'm really tempted to go for one of those !!!!
