Title: Is this BOV fitted correctly
Post by: dturpin on July 21, 2004, 05:33:16 PM
My FD has got a twin K&N induction kit on it and I was just wondering if this Blitz BOV was fitted correctly.
Basically the pipes coming off the turbo manifold go into a T-piece, then go off to the BOV.  Originally there were 2 standard dump valves on it one on each pipe coming off the manifold then going to each filter.  Because of this there were 2 vacum pipes so i joined them with a T-piece and went from that to the BOV, one of them goes to the yop of the inlet manifold and the other goes to the bottom of the inlet manifold, is this ok?

The 2nd one is a Charge Relief Valve which controls pre-spool on the 2nd turbo and not a dump valve.

Im not really sure what you have done from that description.

As you look at the turbo manifold from the front of the car there were 2 pipes coming off each going to what I thought was the standard dump valves, then from them each one went back to one the air filters, should I of left the one from the pipe that comes off the inlet manifold on then.
Would put pics on but can\'t get them down to size.

Mine has had the two valves replaced with one, was brought to my attention when I took it to WGT for a check up.  Was told it was not ideal as wouldn\'t get the power where it should be??? but was not a problem???

Anyway, was working fine for the last 8 months of ownership (although having a small problem at mo)

Can\'t quite make out what\'s going on from those pics (maybe \'cos I don\'t have half of it!)

 AFAIK I have got a big braided hose going from the turbos to the BOV, everything else is blanked off.

Erm, that looks verry wrong. The rear turbo outlet should have a brown recirculating pressure release valve on it and this ends up at the air filter.  The front turbo outlet is where the dump valve goes. Both outlets should not be attached under any circumstances as the rear outlet is not a dump valve as such.
