Hey guys,

Recently purchased the AB Speed catch can off a forum member here and had it shipped all the way to South Africa. Very tidy piece of kit, really cool indeed. I have the -10AN fittings on mine but we are running it to factory PCV port on valve cover and then onto intake manifold respectively.

Just need some help please, we have installed everything into the car now, but on startup my idle is crazy, up down up down up down, extremely erratic.
The car is Rotrex supercharged and I've noticed the dumpvalve does not open at all on startup, like some pressure is being stolen somewhere along the way and forcing it not to open.

I know the PCV port must only expel gases as it is a 1-way valve, we fitted an adapter that came with the kit to make use of -10AN fitting at the end. The problem with it I think is that it's completely open allowing air in & out. We tried again with the OEM PCV part and the same occurs, erratic idling.

Is there anything I'm missing/ done incorrectly? Any help would be appreciated as we've come to a brick wall now.

See pics below...

 

It's a vented can. You need to block off ports on intake manifold and just run the two lines from valve cover to the catch can. Don't run lines from the can to intake manifold.

 

This is correct.

 

Yeah... The line that you have going to your intake manifold is suppose to go to your front crankcase vent where you currently have your mini crankcase filter. Take that little filter off and run that line to it instead. Then put a rubber nipple cap over the port on the intake manifold.

 

Sweet!!!
Thanks guys, did just that and car is back to normal!

Ps. @Ryan - Love the can dude!

 

Glad to hear you got it all worked out!
