It's ALIVE! - I'm boosted!

[Kooldino]

I think it's connected good...I can double check tomorrow.

 

[acidbug]

Wow...I can't Believe How many Problems you are having!! Didn't you say you were having this proffesionally installed??

Sorry to hear about the problems...But if u had it proff..installed you should take it back to them to get these things fixed...

Otherwise..Have you dyno'd it?? and why are u running such a low psi?? I though that you got a different ecu to let you achieve higher boost without problems??

All the stalling problems you have stated occured with my ride in the first week after intalling it. But within a week my problems were resolved by themselves..had a little to do with my BOV leaking at idle. Then again you have the intercooled kit and a whole lot of other places to look for leaks...I could be wrong...but the ECU sort of learns to not stall out after a hard rev after a week or so. Strange but this problem went away by itself. I am running 5psi at the momment.

I am pretty sure the stall is just something we have to deal with. It has nothing to do with building boost. Like you said, even if you rev it in neutral it will stall. Mine does it too.

Could have something to do with the MAF not being far enough away from the filter. It isn't really a problem, just gotta learn how to get around it.

I wouldn't worry about it, just learn to drive it without letting it drop from high rpm.

That reaaaaally NOT should be the way to solve it..There has to be SOME explanation for this..Everyone has always complained about the stalling issue, but pretty much danced around it..I think its about time we figure this out!

 

[Norman@spool]

Ok primarily after one of our kits get installed we get called about an irregular idle or stalling.
There are a few things that can cause this.
There are also a couple of theories out there.

As you may know our kit runs the BOV venting into the atmos, I think FM's runs a recirc setup.

Yes theoritically if you are dumping umetered air into the atmos the MAF does not take this into account and you should stall.
However we have run quite a few cars without any stalling issues venting into the atmosphere including spoolins car. So if this is actually true about atmos venting bov's then why do half of the people out there do not encounter any problems on the same exact car. Also alot of the MSP guys run bov's venting into the atmos without any stalling issues.

Things we have noticed:
Most of the guys with the HKS have had more of a problem than the Greddy bov's

Most people have had minute vacum leaks that have effected stalling and did not track the leak weeks or months later.

For some freakish reason we have noticed that some peoples stalling problems just dissapeared like deep stated.

For those having excessive problems where the car does not even catch itself or stall extremely easy a vacum leak is usuall suspect. Or the BOV is leaking.

For those people with slight stall issues we are still trying to figure this out.

 

[KzA]

thanks 4 the info Norm....whats going on with Terry??

 

[spoolinmp3]

I am here!
I was out of town and we have been real busy lately.
We are holding some shipments due to the fact that we are recalling the dumptubes and intakes. They have to be redesigned and we are waiting on some flared fittings to come in so everything can go out. In regards to Normans explanation we have had alot of people initially complain of stalling and it usually comes down to vacum leaks. We will be putting together a turbo MP3 next week and will experiment with it

 

[KzA]

TErrrrry yay!

When you put together that MP3, take pics and make a step-by-step installation manual..It is in HIGH demand within your customers..

BTW..What would be the best way to contact you about pricing a kit?

 

[Kooldino]

Wow...I can't Believe How many Problems you are having!!

Well, you read the updates, right? Basically my only problem now is the occasional stall *KNOCK ON WOOD*. That may be remedied tomorrow.

Didn't you say you were having this proffesionally installed??

Nope, I did it myself. Although I did it in the shop and a pro helped me out a bit.

Otherwise..Have you dyno'd it??

Nope, not yet.

and why are u running such a low psi??

Safety.
If I ran high PSI, I'd run into problems such as...
1-the stock fuel pump not keeping up, causing a lean condition
2-more likely to knock at high boost
3-additional heat

I don't see a reason to boost above 5psi right now. To be honest, it would be really stupid of me to do so. I'm nervous enough about the engine as it is.

I though that you got a different ecu to let you achieve higher boost without problems??

I got the different ECU to BOOST with fewer problems. I won't boost high until I have engine management.

Yeah, I'm noticing that it's stalling less and less the more I drive it (ie, the more the ECU learns).

 

[Kooldino]

Right, and FM owners don't complain about stalling much as far as I see...

Yes theoritically if you are dumping umetered air into the atmos the MAF does not take this into account and you should stall.
However we have run quite a few cars without any stalling issues venting into the atmosphere including spoolins car.

But you can't totally count spoolin's car because he's running a totally different engine management system.

So if this is actually true about atmos venting bov's then why do half of the people out there do not encounter any problems on the same exact car.

Well, most people who stall, the car just BARELY stalls...change a few slight variables (which automatically exsist between the different cars), and it can make or break the car stalling or not.

Also alot of the MSP guys run bov's venting into the atmos without any stalling issues.

True, but it's a different ECU.

Things we have noticed:
Most of the guys with the HKS have had more of a problem than the Greddy bov's

That's just one more reason that shows that it's probably the BOV.

Most people have had minute vacum leaks that have effected stalling and did not track the leak weeks or months later.

For some freakish reason we have noticed that some peoples stalling problems just dissapeared like deep stated.

The ECU learns over time.

Like I said to Terry last night...I'm not guaranteeing that I'm right in my thinking that the BOV to atmosphere is the cause of a lot of the stalls, but what I'm saying is this: We can debate back and forth all day long about whether it's significant enough to make it stall or not. In the end, my logic is that whether it effects it or not, it's not going to hurt to recirculate it anyway. To update the kits to recirculate would probably take an hour to redesign, and it would probably cost about $2 per kit to do. So I see no reason not to go ahead and make it standard in the kit. I'd really urge you to do that. On top of that, I feel it would help fix the issue if the BOV is leaky to begin with (if the spring was too loose)...since it would "leak" right back into the compressor anyway. Again, no reason not to do it. And while you're redesigning the intake, I'd really like to see it bend down (since there is a good amount of free space between the block/tranny and the IC pipe) to get some slightly cooler air.

Let me know what you guys think!

add i more VERY credible reason.
the stock MAF 's have different voltage ranges at idle AND EVEN with just the key in the ON position. these voltage ranges at idle vary from .6 - 1.6 volts.
many different meters , many different ranges , many of the same vehicles. just because there part numbers match does not mean that they react to incoming air and turbulence from compressor surge the same.

 

[serpentkilla1]

I'm using the hks ss bov venting to the atmosphere, i'm not having that stalling prob. I had that prob the first 2 days. The car was real lazy no power, i had to keep my foot on the gas to keep it running and lot of black smoke coming from the exhaust. I thought i had everything tighten down but one of the pipes still manage to com un-dun. I had a leak on the charge side of the ic. Now that that is fixed the car runs great.

 

[Kooldino]

Perf - So basically you're backing up my "variance between different cars" theory?

I see you've talked with your MAF guy and found out the MAF has an analog output.

hey bill, yes it is.
they did not flow the right meter the first time. some kind of a mix up. all corrected now!!
