can't kill turkey and i'm stalling w/ dual bpv/bov

[505zoom]

you might know a little more about tuning etc. im not sure what your mods are tho you mentioned making a new map . with that at your disposal im sure you could work around it alot more easy then these kids haveing custom fabed pipes or stock plastic pipes rigging them up would

I have not used the MPI tuner to tune the shifts. My mods are listed on my cardomain page, there is a link in my sig.

My first setup was just rigged up, and it worked great. I called DiscreetSpeed that day, and he rigged his up the very next day using a different BOV. Lots of people have since then done the same thing, and this thread is the only one that I have seen major problems in.

Ricer = sound.

Fuction over fasion. Simplicity is the key in tuning, having 2 things to do something 1 bpv can do is ricer to me. If you like the 2 bpv/bov for the sound, more power to you. Still makes you a ricer for wanting a sound.

"the whistle tips go WOoooOo WooooOOO" - Bubba

So I'm a ricer because I have a dual valve set-up?
(boom08)

When driving my car before, it felt very dangerous and I didn't want to drive it especially with my wife in the car because I feared I would stall out in the middle of an intersection. Before the dual valve, I would stall out in traffic if I put the clutch in quickly after inching up or if I put the car in neutral after being above or close to 3k RPM's. I even stalled out on an on ramp to a highway. I guess I downshifted too slowly going around the corner and it stalled out on me. Very scary with many cars behind you and knowing that your stearing cut out on you on a 180 degree turn.

Now I have no problems at all. The RPM's fall slowly to 750 after shifting into nuertal in high rpms, and I no longer worry in traffic.

Please watch what you say, because I speak from experience and am extremely grateful to 505 because now I can enjoy my car without any reservations. I did not do it for the sound, but for safety.

Great post, thanks man... glad it works good for you too.

I can really care less if you were the first to buy a msp. Fact is fact, you let off air that is read, the ecu will send fuel to accomadate it. What happens when there is fuel but no air?? you bog.

I've been tuning turbo hondas and nissans for over 3years and consider myself an expert when it comes to turbo engine tuning and installs.

I've seen some sick crazy turbo setups here, not a single one is using bpv/bov. Like i said they do the same thing, one just makes the sound.

There are dual stage bpv that keeps it fully closed in low boosts and reacts quick in highboost.

bleh to each his own , i could careless really about ricer s*** . its about performance to me . your set up seems reasonable . (2 valves tuned properly can relieve pressure faster then 1) but i totaly belive that either 1 BPV or even 2 BPV can be tuned to work properly with minimal or zero surge inturn producing better performance . obviusly not the stock one tho

Send me a PM if you ever need any help with your setup, I won't jack your thread anymore with this.

 

[Autox MSP]

Mark94, You wouldn't even have had that problem to begin with if you had recirculated your Bov.

exactly you want that noise.

hes obviusly talking about his experiances with venting only NOT bpv only
because with just BPV there is no problem to begin with

 

[Mark94]

Mark94, if you were worried about stalling then why not just get a recirculated bov??

exactly you want that noise.

Check it out my man...

What do you see here, THAT's RIGHT... A RECIRC FITTING ON MY BOV!

That's the way Essential Speed designed it and I payed for the fitting because I did not want to stall. I just wanted to recirc. I didn't care about sound... just performance.

505's discovery eliminated a flaw in the system.

Stop being a putz and realize that this set-up is useful for some people.

Now I'm left with this recirc fitting on my BOV that is getting no use... Oh Well, at least my car is driveable now.

 

[Autox MSP]

explain the flaw?? so you telling me that you were stalling with the bov reciruclating?? because that would fuction like stock, correct me if i'm wrong. Unless you had the wrong spring in the bpv.

I've never ever seen a recirculated bov car stall. So if your telling me that ours does, i would say its the way you installed it.

 

[NoVaMSP]

mark here is a pic of a single BPV that wirks fine and is quite loud

has any one ever done side by side befor and after same day tests on a track or a dyno with a maf car venting ??

Thats the forge bpv, direct bolt on for your cars. No need for the dual setup.

Ofcourse the Hiboostkit comes with the HKS racing bov recirculated. I've used the HKS on a turbo MAF equipped 240sx with no problems at all.

The ES intake places the BPV return flange too close to the MAF. The incoming air creates turbulance at the MAF, sending a false reading to the PCM. In Mark's case, now that he doesn't have all the air that was coming out of the SSQV going into the intake, he doesn't have that condition.

That thing does not get rid of the surge... and despite the minority opinion in this thread, getting rid of it is NOT to get a car that sounds like it was in a stupid movie.

 

[Mark94]

Yup, stalled with the HKS recirculated. That is why I bought his kit even though it was much more expensive than any others. I wanted it to function like stock coupled with the performance of a FMIC.

The HKS had the original spring it so that is not the problem. The spring is also adjustable and I adjusted that hing fractions of an 8th of an inch to get to no stall. Nothing worked. People from this board stopped by out the kindness of their heart to try and diagnose it but no one could.

Later it was thought that the recirc fitting was too close to the MAF and some of the air was pushing back to the the MAF when recirculated so ES sent us all new intake pipes with the fitting about 4 inches further away from the MAF. I was so excited to take it for a drive after replacing the pipe but it still the stalled.

At this point I had invested so much time and money in trying to find a solution and ES wasn't helping any, so I figured that I would give this a try. I didn't want to hack into my pipes for something that may not work so I put the stock upper intercooler pipe back on and rigged the stock BPV back on with the help of some items from Home Depot and low and behold, no more stalling and no more surge.

The next day I was looking in the phone book for welders who could weld a fitting on the upper intercooler pipe from ES.

Had the fitting welded on and haven't looked back since.

I spoke to 4 other people who have the ES kit and they all have the problem also. After everyone telling me that I have a boost leak, I ruled that out because how could 5 people install a kit with a bad connection?

ES has now said that it is the HKS that is causing the stalling. Something that it can't hold the pressure and is leaking air.

I don't believe that at all.

The dual valve set-up worked for me... that's all I can say.

[NoVaMSP]

so what yer sayin is the ES intake is crap ? isnt the injen really close also ?

 

[Autox MSP]

okay, then the ES piping is the calprit for their piss poor engineering. But for the rest of us, its not warrented.

People here have PM'd me that have the HiBoost kit and want to know how to hook up the dual valve set-up because they are stalling also with the HKS recirculated in the HiBoost kit.

[NoVaMSP]

also would it be possible to buy a diff maf like a blow by that might not be affected by air passing it ?

The original prototype injen made had the same problem. It was on Spicy's car.
