hahahahaha...chicks dig the bov...

 

im glad we came to that conclusion. it kinda makes you wanna take it off when your mom thinks its cute tho...

 

well all my life i had N/A cars so i love the sound and chicks dig it.hahaha i admit i have a ricer fetish.hahaha

 

seriously they do.... haha

 

if i was a chick, i'd get wet hearing it...

and it reminds me of my race and culture (i'm 100% filipino)....pssssssssshhhhhhhttttt

 

i dont know but im gonna find out again when i go tracks this weekend, cause i just sold my blitz bov and it was running fine, but when i bought the turbo xs type h-my car felt slow at tracks and i could just feel the difference, i don't know could be just a bad night. anyway i put my stock one back on and drove to likelike to h3 to test it out and it felt much better.

 

so do men...
old ladies get scared by it.

I just got the APS 50/50 bov...my car seems much happier. Shifts are smoother, no lag like I felt with the stock recirculating valve (did the silencer mod)...idle is normal...

Before doing the silencer mod, I could not hear the stock recirculating valve...after, I could hear a distinct but subtle"whooosh".

My APS pretty much sounds the same, volume and pitch wise until I get it up to 5k+ RPM's...then it vents part of the pressure to atmosphere...sounds nice but definately not loud...I know because my cousin has an STI as well with the RFL...that thing is loud!

 

I know some of you don't want this to turn into a tech discussion, but it's a comment that is in dire need of a technical answer.

Many if not most stock diverter valves will leak at higher boost pressures. This has been tested many times by myself and others. If a valve starts to leak at say 19 psi, and your target boost is 24 psi, you'll be running the turbo harder that it should to obtain 24 psi at the intake manifold. As the compressor head psi goes up, the compressor discharge temperature goes up, creating more heat for the intercooler to relieve (which it cannot), and ultimately creating a higher intake temperature, and making less horsepower.

If you are running less boost than the stock diverter valve will leak at, then switching to an aftermarket blowoff valve will be nothing more than a noise maker. However, if you are running boost above the leak-point of the diverter valve, then you have a boost leak that is costing you horsepower via higher intake charge temperatures. In that case, switching to a properly configures blowoff/diverter valve will be like picking up a bit of intercooler efficiency, and you'll be working the turbo a little easier for the same intake psi.

 

Only 'cause this is the regional forum and we try our best to keep tech stuff in the tech forum for the benefit of all (and 'cause Imprezer has so requested it)

 

why does anyone throw away $$ on fast and the furious??

or was that just me. b

 

I run the type-h on my car...

I only bought it because the stock on started to leak at 18psi... I run around 19 to 19.5 peak boost. When I first put it on the car it didn't seem to run right, but after I put in the correct number of spacers it works great. It holds boost and I peak at 19 (give or take a little) and hold 17psi to redline. If I wouldn't have needed to buy one, I wouldn't have... I personally don't like the attention that it can bring to the car. Not that my yellow car doesn't catch anyones eyes anyway...

 

yeah i think i need those spacers also, do u or anybody u know have an extra one laying around-cause i had to put back my stock bypass valve, because my car didn't seem to run right also.

i didn't know this until justin(04sleeper) told me at tracks.
so anybody with spacers pls let me know.

yo rudy, you can use anykind washers that are about the size of a quarter. maybe a lil' bigger.. i bought some washers at napa and they work fine...

 

thanks men, do u have extra ones? if not, how much is it?
