What is my freakin' problem?

[StreetStyleJPTI]

I know I am a pain in the ass, however, I do apologize for the inconvenience. (updated)Well, I have a new factory turbo on the way, but I am still trying to figure out if that was the problem all along. If you don't already know, I have an issue with over boosting...and when I stomp on it, in 1st, it sometimes doesn't build boost... but the rest of the gears seem to...it also seems like its to quick to build boost...like there should be more resistance/hesitation...but when it boosts, it shoots up to 10 psi+. My boost gauge reads 21-22 HG idle...and 23-24 when I let off the gas and I'm driving. No manual boost controller...WGA has been replaced (a week ago)...just have a AEM CAI and Greddy RS BOV...all vacuum lines have been replaced and zip tied/clamped tight...no unusual smoke...Also, when I'm driving I can hear this weird sound, but not all the time though...just usually at lower rpms when I hit the gas, and it's not a whine/grind/or whistle...not turkey either...it's like the sound you would hear if your car into 5th right away and floored it (at lower speeds where you should only be in 1st) and imagine that sound a lot louder and more distinct.

So...what's the problem? the noise? over boosting?
my car will not build boost in first either, never seen an issue with it.
all your vacuum readings are correct
it's a small turbo, its spools fast and dies quick
is that noise your cai? it's going to make incoming air sound a lot different.
if you dont have any boost control i cant imagine anything other than your wastegate or line to it,
sorry im not of any real help.

 

[StreetStyleJPTI]

I know its not the CAI (the sound is new and different). The line to the wastegate is perfect.

Is it dirt slow or does it run hard? You won't ever build boost (at least on the gauge) in 1st.

 

[Mark94]

Mine never builds boost in 1st too. Never knew that was normal and thought it was odd so thanks nvmsp.

 

[BradC]

I build boost fine in first gear

 

[StreetStyleJPTI]

I wouldn't say it runs hard, and its not really slow. Like I touch the gas and boom I'm up to 8...10...psi+.

 

[Jaysanooch]

The problem is...you don't have a problem.

1. 1st gear is very torquy to begin with...you won't feel the build up like 2nd gear and on.

2. Spikes... well you most likely had a weak WGA but it didn't help by putting an aftermarket ATP WGA.

3. I would get spikes of max 9.5psi and held 7.8psi when on stock boost with my ATP WGA so...that sounds normal to me to. Who knows how accurate these thing are made.

Try another WGA and also try shortening the vacuum line to WGA as much as possible.

I'm not saying it won't build boost in 1st, I'm saying it won't show up on your gauge.

 

[StreetStyleJPTI]

It is a problem, because it isn't a spike. It just builds boost and keeps going.

 

[BradC]

I'm not saying it won't build boost in 1st, I'm saying it won't show up on your gauge.

And I am saying sure it will. Mine does and always has.

 

[StreetStyleJPTI]

I've been in an MSP before where it hits 6 psi and stays. But of course, not mine!

 

[nvmsp]

And I am saying sure it will. Mine does and always has.

What boost gauge do you have? and Ask others if boost shows up in 1st on their guages.

Mine never has shown boost in 1st and I know many others who will tell you the same. It doesn't even only apply to msp's. I've seen the same thing happen in RX7's, 1st gear is too quick.

 

[fr0st]

mine appears in 1st gear.. just a little.. 2-3psi maybe

SW boost.

I dont understand why it wouldn't show boost? The car is making boost, so the gauge shows it, no?

 

[StreetStyleJPTI]

the gauge reads to 10psi (i dont push it any further). It builds up to that (no spike) I mean it seems to build quickly if that makes ense...like i hit the gas hard and a couple seconds later and im at 10psi.

 

[shane02pro5]

Let's talk rpm's here and beyond 1st gear. What rpm's do you hit full boost in 2nd and 3rd?

 

[mspHtown]

I'm not saying it won't build boost in 1st, I'm saying it won't show up on your gauge.

man im sorry but how dumb is that? i can hit a decent amount of boost (and it shows up clearly on my boost gauge) in first gear. my friends wrx shows boost on the guage in first gear. my friends turbo gsr shows boost in first gear.

our stock turbo spools faster than s***. if it isnt showing up on the gauge then something is wrong.

 

[terbow]

sometimes u cant get in boost cause of the lack of engine load. thats why 2-5 will show boost. when u have a boost controller thats y they tell u to test in a higher gear, cause u might not be able to get enough load for the turbo to spool to full boost in 1st or even second. it depends on car, if ur on a hill etc.

but yea, if ur making boost itll show up unles ur gauge is broken. thats just silly to think it wont show cause ur in 1st but its really making boost.

I didn't show boost in first until i went to hard pipes, intake and a catless exhaust .... then I finally could boost in first ...
