Dual Port Blow Off Valve!!!
 

I know what you guys think about BOV's/dump valves but has anyone got a dual port BOV? I was wondering if you still get the running issues and/or bore wash with this as it partly recircs the air and partly vents to atmosphere.....

Dumpvalves don't cause piston slap fella. :thumb:

Meant Bore Wash....thanks for pointing that out :-)

Anyone....?

i heard they cause lean running ?

Why bother, 2 much negatives for a whoosh noise lol
