yeah his pic is def misleading. i had to back track his posts to dbl check. imho the greddy and hks are iffy. i dont like the fact that the newer ssqv's arent adjustable. i just ordered a synapse from paul @ dezod. i hope itll be here this week so i can get rid of my ssqv.

i have a synapse for my new set-up myself i am excited about it for sure. i just wish it wasnt so ugly.

The synapse isnt that ugly. Lol. But who cares if it is, id rather run efficiant and ugly than look good and run like poop.

I get no flutter with my Turbosmart.

yea tial and turbosmarts usually dont get flutter.

and pearl wait until you hold your before you say that. it's uglier in person

haha idk wat to do i guess deal with it im thinking its a combo of the 63 trim t3/t4 and my small exhaust 60mm.... idk thinking about making a 3 inch back system

I dont think thats gonna gonna help man. Ur flutter is on the cold side not the hot side. So i dont think exhaust size will matter.

Vindiesel075

ya i know lol i dont know what else to do man!

Try a synapse or a tial. U can get a synapse w the hks flange. Got mine ordered up from paul for like 230.00 plus freight n shipping. And thats w the hks adapter. Ur better off spending a lil bit now and prolonging the life of ur turbo or u can spemd more later and buy a new turbo.

Turbosmart BOV will even vent VAC. I watched my boost gauge and anything over 10 Vac I hear the BOV and release the pressure. My dual BB starts sounding at around 10-11 Vac anyway.

the tial and turbosmart are made to stay open at idle and close under posotive pressure is why they work so well.

+1 on pearl exhaust has nothing to do with flutter.

dont sweat it. it gets the job done hayseed. not all of them flutter and suposedly the RZ doesnt he is saying his HKS V1 flutters which all HKS' do.

ive seen it in person. it looks ugly w the anti stall kit on but without it looks fine. lol...but to each their own.

Haha - yeah noticed my tial was open at idle and was like wtf? Than after some research, found out it was normal

Vindiesel075

The RZ flutters as well i switched to the HKS because I thought it may work better but it surges with it to.....Like i said though i get no flutter at full boost just at like 0 to 3lbs even as 6lbs i dont beleive that it is enough to damage...

make it soft. like only do 3 to 4 turns from all the way out. i had almost no flutter on my RS and i think mine was an Ebay RS

Huh? If the BOV is open at idle, wouldn't it be allowing un-filtered, un-measured air to enter the intake post-MAS?

I just checked and Turbosmart specifies that the piston should be tight against the seat (closed) at idle and not even fluctuating. If it does move, they recommend increasing spring preload until the valve remains firmly closed.

Tial sells different springs designed to match engine idle vacuum to ensure that the BOV remains closed at idle.

I'm very certain that any BOV should remain closed at idle and only open when the pressure between the throttle body and compressor exceeds atmospheric pressure. Unfortunately this often results in some audible compressor "flutter" when the turbo is spinning up and the throttle closes abruptly but it's normal and won't hurt anything.
