sory for newb question but why wouldnt it matter with map sensors??

 

B/K with a MAP (Manifold Absolute Pressure) set up air flow is measured at or after the Throttle Body so the intake air that is vented by the BOV is never measured, With a MAF (Mass Air Flow) system if the BOV is DOWNSTREAM of the MAF sensor (and most MAF sensor are mounted UPSTREAM of the TURBOS in turbo applications), it vents air that has already been measured and could cause RICH A/F Ratios, HOWEVER this is not as great a problem as it may seem as the BOV only vents when the throttle is closed rapidly, and during closing throttle transitions the ecu will be cutting fuel flow sharply anyway.

 

The base map of a Power FC has better tuning than a M2 ecu, it doesnt need any tuning for the mods he's running.

For the record guys, I'm runing the stock BOV's with BNR hybrids at 17-18psi with no problems at all...plus I love the sound of the stockers.

THAT is why I love my BLITZ!! its different.

 

I like the sound of the Blitz too. But my best friend is running a hard tuned WRX with a Blitz BOV and it leaks boost. It may not help that he's running 19.5lbs. of boost, but none the less. I don't want to take chances on leaking. Just my .02

Apparently the Blitz BOV's are famous (or infamous) for leaking when they start getting older.

 

does ANYONE know how to get the HKS SSQ for our car under three hundred bucks? Every where I check, its mad expensive. Couldn't I just buy the valve, a flange to fit, and weld a pipe to the flange and route it to the existing stock hose, instead of buying the "elbow" piece? I don't even know what this elbow piece that adapts to the stock configuration looks like, but from what the stocker looks like, I don't see how fabricating some sort of flange would be that hard as long as welds are done well.

 

my blitz never leaked on my 7 lb honda...

but the gasket tore on my FD.
lost boost and had to replace the gasket.

probably buy a new one when i up my boost to 12-14 or something.

 

Stevey629, if you want an HKS for cheap, PM me. I can probably hook you up with one for a cheap price. Just give me your lowest quoted price and I will do my best to beat it. Laterz.

You know, I have been in the industry a while, and have heard this too, but, much like the Autometer quality question, its generally from people with second or third hand knowledge. I have only seen a Blitz BOV fail once, and it had the soft spring in it, that was the problem.. We replaced it with the stiff and it worked perfectly

I have had a Gen 1 Blitz on my turbocharged Neon for about 4 years now, and it doesn't leak, even at 22psi




I have a Gen 2 Blitz on the FD because I had such great performance from the first. It sounds awesome (I prefer the 1st gen one actually, I may switch them) and should be adequate for the upgrade path I plan to do.. If I have to, I'll add another one! Althought I don't think I'll ever be making enough power to warrant that.

 

thats a pretty clean pic.

 

A Neon boosting 22lbs? That's nutz bro. You must have one serious powerhouse there. Congrats on getting that engine to hold together!! What's your mod list on it? I generally hate Neon's, short of the ACR anyway, but I'd like to hear what you have done to it. What do you plan on doing to your FD? Laterz.

Zach

P.S. I have presonally seen both a Blitz and a GReddy Type S fail. Both were around the 19 to 20 psi mark though. Kinda tough for a BOV at that pressure. That's why I'm a fan of the HKS SSQV.

 

Neon Specs

There's everything that has been done to it. Needless to say its not much fun to drive on the street with a 4 puck solid hub clutch and fwd/no LSD.. 30 mph roll ons are brutal tho, the local supras tremble =D

But to keep this FD BOV related, here is a pic of my blitz genII location





My main plans right now are mazdaspeed bushings (DAMN they are expensive!) , suspension and wheels/tires. It has 82k on it so its a little rattley. I plan to get as many miles out of the engine that I can, then get a street port, upgraded twins, and a paint job.

 

Very nice bro, very nice. I may have to look you up if I run across anything that I need custom made for my FD! Laterz.

Im not used to turbo and blow-off valves but i have a question about my stock one that i would like to have answered. My bov blows when im on vacuum. Is the bov malfunctioning??

 

I like the A'PEXi dual chamber mostly because it was on my car when I bought it so it was kind of free. It has a good wooshing sound at low boost and a pshhhht sound at 10psi. Not obnoxious at all.

 

get the blitz dude...

When people hear the whoosh they know what sup, but when they hear the high pitch whistle sound (hks,....etc) they might think it's just some ricer fake BOV cuz it sounds like those...

 

My project speaks for it's self...

What did you do to make it sound as loud?

 

Wow..... Gotta love these BOV threads...... I picked the stock cuz well, cuz there's nothing wrong with it that needs to be replaced in the first place.......

 

Wonder if you guys know of this site

http://www.935motorsports.com/bovmultimedia.htm

I like the HKS cuz its reliable for up to 18psi (correct me if im wrong), also i've never heard about any problems relating to it. You should get whatever you want cuz its your car. At least it's not one of those cheap *** 50 dollar pre-recorded BOV sound device that i see on magazines...

 

I take it that you have vented your stock BOV. Have you had any problems with your car since? I am still deciding because of the issue w/ it either being a one way valve or not.

 

The fact that the BOV and its sound quality is the most often discussed subject on this forum is complete proof that the FD has dropped to the price range where kids are buying them.

It is a shame really.

I saw an FD a month ago and its 19 year old owner told me (somehow with a straight face) that once he installed his 2nd BOV his 1/4 mile time dropped 4/10ths (he had a huge red BOV in the IC piping and had the stock BOV still in place.

He didn't have a clue, but ignorance didn't keep him from bragging to everyone who would listen that his car had the best BOV sound in town.

I think if I see another BOV sound thread in the next week it will be a certain sign of the end of the world.

 

WVRx7, Your such a party pooper. ;-)

I just got a JDM blow-off from "RE Roscoe" that added 15 MPH to my top end, so that now I can easily break 200 MPH when ever I want to race.

Best of all, the "Maxi-Kudzu Nueral Network Blow-Off Valve" plays "Dixie" every time it vents,

 

I agree with you 100%. I have had my car 4 years now, and month by month this forum continues to go downhill as far as Q&A goes. Most of the knowledgable tuners have left, and now it's just kids asking about NAWS and loud BoVs.
