Fitted 2 HKS SQV blow off valves 2 days ago and the car has runperfect until this morning on my way home from work, now idles like a pig, the car also feels gutless on pick up and the valves sound like they are blowing off OK, any suggestions???

 

Also, how do I post some pics of my new car on here as I have had it 6 months now and want to see want people think of it.

 

Thanks for any support

did you remove the OEM dump valves and if so, check your bungs to make sure they havent fallen out. also check all intake pipe work to make sure they are tightened down and no unmetered air is entering the system, pay close attention to where the dump valves where fitted, sounds like you have Air coming into the system from somewhere other than the airfilter.

 

as for photos, click the attach image button and upload one that way, or you could use photobucket.com

I agree with vods if it was working before you added them its probably something to do with the way they were fitted. The recircs may have nbeen letting by and now your producing better post pressure resulting in popping off a hose, or you've disturbed something which has poppd off. boost leak check buddy, thats the bets way to start.

sounds like there leaking on vacume

I dont use them anymore due to issues ive had in the past where by after 20psi of boost they force the circlips out and become unseated had this a couple of times so maybe worth seeing if they have popped there circlips hard to believe with how difficult they are to get in i know

Just checking, but had same issue with my evo, it wasn't dual piston, changed for dual and all fixed :)
