i recently installed the APS BOV in my 05 EVO and have had no problems at all, top quality.. below is a link to the APS BOV thread, it has pics and a sound clip along with the distributor for the APS BOV. I hope this helps...

The install took me 10 mins and I havent had a single idle issue, I can take my car to full boost in any gear put the clutch in and let the rpms drop with NO bounce (stock airbox and maf) The car has zero flutter from just letting off the gass from boost too. This bov is THE best bov I have ever seen. This comes from someone who has owned almost every type of mayjor bov there is. I cant recomind it enough.

 

NONE, like I said in other post the bov is just to good to be true.. Its worth the wait. If you get backorder.

 

any of you guys with the APS BOV have to adjust it after installing? or was it like Ron Popeil with a "set it and forget" kinda thing...

thanks

 

ya... whats the little nut on top of the bov for?

ya... thats the exact way i install it... but i do hear flutter noise when i let off my gas during low boost

 

Depends...i get that here and there. Doesnt always do it. Ive grown accustomed to slowly letting off the gas and i rarely have this happen anymore. I dont get it in 5th gear. Mostly my power gears...3rd, maybe 4th. It could have something to do with the screw setting. I am tempted to play around with it.

Set it and forget it, works in this application, for me and many others.


what nut? On the back side of the bov facing you?

 

When I first got my aps bov I put it on backwards. Once it was on correctly it worked awesome. It is not a loud bov but seems very effective.

 

Its already dialed in......install and forget it

 

the arrow pointing to it

 

The white arrow on the backside of the bov facing ou when you open the hood is the adjusting nut (allen key) for how tight or loose the valve will be.

 

That is the locking nut for the adjuster. loosen that nut and then stick a hex key in the top. Turn it clockwise to stiffen the BOv and counter-clockwise to Soften the valve.(lefty loosey righty tighty)

It comes set fine. But you can fine tune it if you wish.

Thanks for all your orders guys. We have these on the shelf so the backorder is over. We plan on having them instock all the time.

Let me know if you have any questions. We have installed these and played with them and know all about them.

AHHHHHHHHHH you beat me

Ben

 

thanks for clearing it up for me

 

that could be a bit confusing. You'll want to stick the hex in the top of the screw. Youll see it.

haha the funny thing is i came back to edit my response to put in locking nut.

 

Yeah, I definitely like the APS better than the MR bov which I had.
No studdering or idle problems here, all I hear is whoosh!
My MR bov had stalling issues?
