IS IT A RECIRCULATING ONE?

 

Yours looks like the old HKS dump valve, dont know much about these... it does look as though the srew on the end is screwed to far out...

Dan

 

no its vent to atmosphere..!!! some dump valves dont work with the scoobs MAF, dont know if the old HKS ones where ok, mine is fine though....

Dan

 

ITS AN OLD STYLE HKS WITH TUMPET, I HAVE NO PICTURES

 

SORRY TO APEAR STUPID BUT WHAT IS MAF?

 

MAF = mass air flow sensor....!! some dump valve cause idle/drivability problems... thats why people like www.forgemotorsport.co.uk and www.baileymotorsport.co.uk make specific twin piston design dump valves that dont cause problems.....

The MAF sensor sees the air that is dumped as lost air and causes fueling problems.... the new HKS ones and alot of new ones are made to work with MAF sensors.....


Dan

 

IT HAS NO AJUSTA ON IT

 

ITS GOT A BLACK BIT ON THE BACK BUT THAT DOES NOT COME OFF

 

is this the one your talking about
