boost creep help??????

[cbr600teardrop]

what do you mean buy type properly? iv been using ispell

 

[LandoAWD]

Oh hell, here we go:

"buy" is not the same a "by", for instance. "iv" is not the contraction "I've". I assume you're old enough to drive, thus you should be more than old enough to spell at a third grade level.

Also, capitalization and punctuation go a LONG way in keeping you from appearing foolish. Not only that, but people will put in effort responding to your posts; is it not fair that you put effort into your posting?

Any other questions, PM me or read the rules 3 or 4 times. It'll sink in.

Don't think of the air coming out of your turbo as a pressure. Look at it as cubic feet per min. PSI to PSI from one turbo to the next is not exactly the same.

Next subject, this 38mm wastegate you speak of, how do you make it work, as in threading it through the hole, and sealing it to the the port? Pics of this bad boy and maybe even an install?

Sorry for the bad grammer i am from ky.

I would loose power if i put a 50trim on my car?

 

[JusMX141]

I just feel elitist about my internal gate which is 38mm and forces me to run 20psi minimum.

You mean minimum or maximum?

Most guys can't keep 34mm flappers closed above 20psi....I can't imagine how much a 38mm flapper would be trying to blow open. We ran into this personally on my buddy's car. I ended up getting a AGP actuator for a SRT4 turbo and modifying it to work:

why would i have to run a 50 trim at 10 psi when i can run my 14b at 16 or 18 psi why couldnt i run the 50trim at the same psi i mean 18 psi is 18 psi right?

In terms of airflow, the 50 trim generates about 50% more air than your 14B at any given boost level. That means that your boost level would have to be set around 1/3rd less than it would with the 14B in order to not overrun your fuel system.

I would think your car would feel slower at 10psi with a 50 trim than 15-16psi with the 14B just because it's a bigger turbo and would take longer to spool. No sense waiting forever to make 10psi.

I initially threw 10psi out there as a safe number to run....without a logger, you have no way of knowing what the magical number is.

Well what if i get bigger injectors and a afc?

Useless if you can't log the car.

 

[cbr600teardrop]

What kind of logger would you suggest?

 

[shaggyslaser]

Get yourself into DSMLink, it'll help you out in the long run. Skip the logger and the SAFC.

First, run a line right from your lower intercooler piping to your WGA (wastegate actuator) to see if the problem is actually your boost controller.

How high is your boost creeping? If it's 20 or less, just get injectors and an afc, or better and cheaper- EPROM tuning. The power difference is huge from 15 to 20, even on a 14B turbo. My talon has a 14B on it and even if I turn the boost down to 14 (making it a real dog), it doesn't creep at all with 3" turbo-back exhaust.

I thought mine (Evo 3 16G) was creeping to 25+ but it was just a crappy boost gauge, I wish I wouldn't have ported my turbo to help the creep because now I can't get over 23 psi at higher rpms no matter what.

As for a logger, my favorite is tmolog with my laptop.

 

[cbr600teardrop]

Anything cheaper than a dsm link? Or would that be my best bet?

My boost controller says my highest is like 19 psi.

 

[DSM90AWD]

To the O/P, I think you need to step back and figure out what your goals are with the car prior to throwing parts on. Maybe start with the DSMTuners FAQ/Upgrade Path ?

Now...about using the Edit option instead of making 3 posts in a row...

I mean minimum. I have a mounstrous spring.

And to the OP... what makes you think you wont' have the same creep problems with the 50-trim? In my opinion you will have worse creep with the 50 since the boost you will be attempting to run (10-12psi) is much less than the optimal efficiency as compared to your 16G.

 

[cbr600teardrop]

From what i have read on here the turbo housing is bigger to allow beter flow witch will do away with the boost creep just like porting my 14b.

 

[JusMX141]

From what i have read on here the turbo housing is bigger to allow beter flow.

....just like the 3" exhaust allowed better flow which caused this whole boost creep mess to begin with?

Bigger isn't always better, my son.

 

[cbr600teardrop]

YEA but i could either port my 14b and get a adjustable wastegate actuator get a 16g and do the same or get the 50trim a data logger like dsm link and some bigger injectors and be better off.

Porting = Free
34mm flapper = $26
Running 15psi on your current setup = Free.

Total cost, $26.

_________________________________________

SBR G50, PTE 5031E, etc. = $699
Oil supply and drain line kit = $60-$100
DSMLink = $550 IF you're lucky enough to have an EPROM ECU
EPROM ECU = $150-$200
FIC 650's / PTE 680's = $250

Shooting high, that's $1799 spent.

Good luck!

I'm sorry. There's just too much stupid here to abide.
