Got it, like it, recomend it for mid level mods, and for those who do not care for ricey vta.
It's solid, durable, and works well to 30psi. The logo, Absolute Power Superiority, is cool too.

 

I have it and love it. No stalling issues or idle problems.....................
You cant hear it under normal driving conditions or when you rev your engine, but when you get on it you can hear it.

 

I just want the most reliable bov that can hold boost well. I will be turning up the boost and adding mods later on. If there is a better bov that is mod freindly please suggest. About the forge one i missed the group buy so that sucks.

 

tial BOV holds up to 40psi i believe... i had tial but since its VTA...i never experience with it... i now have APS... to say the least... it holds boost better than stock but recently after installing the EBC... the boost isn't holding stable at all... i thought it couldve been my setting but i had the same setting for over a month with no problem and now it keeps hitting the limiter... i have greddy profec B II by the way...

Your problems are in your EBC ,chek your gain to be low as posible and set gain no to exeded 10% to 15% if you are boosting at 20 - 25 psi. then your warning light shoud be clouse to the star Boost so it will open fast and it will hold., The APS BOV is one of the best for stock or mild mods cars . But if oyu are going to go Big like a Gt35R then you will need use TIAL BOV .

 

My opinion quoted on the first page of this thread is just that; my opinion.

I have played around with an APS valve a few months ago, and I can fully respect the design and the product as a whole.

I just don't believe in the use of 50/50 valves.

In my experience, I have found that a 50/50 valve provides no functional benefit over that of a solely recirculating valve aside from a slight increase in atmospheric blow-off valve sound.

Another thing I don't like about it is that they use brass for the main piston. The thermal expansion properties of brass is much higher than that of aluminum and has the potential to to cause expansion of the piston under high levels of heat which can inhibit the movement of the piston.

Aside from that, it's a nice product and people seem to have had good experiences with it.

--------------------------------------------------------------------------------------------------------

The only reason I mention the issues with brass pistons is that we used to use brass for our pistons in our valves and occasionally experienced those problems. We are now using aluminum and have never experienced thermal expansion issues.

If APS has taken steps to prevent these potential expansion problems, all the better, but I have never found any information to that effect.

 

i have it.........works great....i got it because after alot of research the APS was the only DV that didn't have any driveability issues.......i was going to get the JDM MR but some people said they have had issues with them

 

im boosting 21 psi.. i had gain set at 13%...no problem for a month and now it keeps hitting the limiter...

 

I concur 100%. Bulocal is the one who got me into APS. Shortly after, i began a few appreciation threads about how i loved APS. Ive had the stocker and the MR DV valve with my hks intake. I experienced stalling with the MR. My Stocker was leaking. I gave APS a shot and it worked great. Ive had mine in for about 15k miles. Recently, i changed my HKS filter to a cone filter and i have had no rpm decrease as i once had with the sponge filter (nothing major though, couple hundred rpm dip at idle and then raises back up).

 

i have an aps bov and couldnt be happier. makes a nice whoosh under boost and drives perfect

 

Like others have said, it doesn't vta unless under full boost. I like it because it doesn't have the whoosh sound everytime I shift between gears, only when in full boost. Easy to install too.

 

everyone who has the aps what other mods do you have and what boost are you running? How do you know the aps will hold 30psi?

 

I did some testing between stock and APS

I set my EBC to boost at 21 psi

on APS - It boosted 21 psi and holded strong like i wanted

With Stock BOV, i had the same setting and it only boosted 16 psi..

the stock DO leak under high boost and doesn't hold too good neither..
