bullseye housing fixed creep sorta

[SRiz]

I just installed a bullseye housing on my 14b and it used to creep to 21psi now only 15psi so defenetly better but i flipped up the wastegate and it opens MAYBE 45 degrees! what the hell its 38mm i know but it should go 90 am I wrong has anyone ported it so it goes 90 degrees... also I have a stock 2g manifold and stock 2g 02 this ###### isnt helping in the creep...

The flapper doesnt open that far anyways.

Why are you only running 15psi?

 

[CanadianTSi]

Yes you port the edges so it can open further.

 

[SRiz]

the wategate is set to 9 psi! and its creeping to 15psi it shouldnt creep

The key in porting for boost creep is in the turbine inlet. Without properly porting the inlet, anything else is just hit or miss. Getting that housing for a 14b for solving boost creep is basically a waste of money, could have easily done it with your original housing, not to mention the well known possible leaks in the mating area between the center section and the turbine housing and possibly losing a couple hundred rpm in spool up time as well.

What RPM is this creeping happening?

Do you have a boost controller?

How is the boost controller hooked up if you do??

 

[oldman]

On a side note, if you plan on running more than 15psi, you will have nothing to worry about.

I would recommend you to port your 02 housing to get rid of that unwanted creep.

You see, you have a newer housing with 38mm wastegate flapper, but maybe your 02 may be restricting that flow, specifically the area were your wastegate bleeds unwanted exhaust gases, thus preventing building boost.

I have a boost contoller but its just hooked up to the wastegate right now and im ###### gonna run 17 psi so ## right i really dont care... better than creeping to 21psi ...ne way the reasons behind me getting the housing was obviously stop the enormuos creep and it is FULLY transferable to a 16g which is gonna be one of my last upgrades, and i hear a lot of creeping on 16g so ill be good there.Imma port the 02 and exhaust manifold soon I dont mind turbo lag cause it still is a 14b so w/e thanx for all the help

 

[Stapl3]

Imma port the 02

That was your ENTIRE problem the whole time, not the housing. You're wasting your money and time with that thing.

Learn how to put a coherent English sentence together please. Also, I'd suggest doing more research on why boost creep happens.

yeah i didnt do to well in Engrish... Ummmm the only reason I got this is cause i hear the 16g is major sux0r in creeping even with everything ported... so yeah i like wasteing time and uber money to pwn my car!

Well you heard wrong. Boost creep porting is different from most turbo vendor port jobs which mainly addresses improving flow and spool, not boost creep. You came on here asking for help because whoever misled you to believe that a Bullseye housing will solve your boost creep has been proven to be wrong so stop arguing and start listening. The key to solving boost creep through porting is in the turbine inlet where the wastegate path begins, the bullseye housing is no exception. Read through these two articles so you'll get a better idea where and how much to port.

I understand and agree with you. The bullseye housing almost fixed my creep and I'm sure that if i port my 02 housing it will cure it. For now I have no regrets getting the Bullseye housing it did exactly what i wanted it to. I'd like my stock boost to be 10 and high to be 17 but I can deal with 15 and 18. Im not gonna port the Bullseye Housing, but thank you for your help I accomplished what I wanted, and when I do get the 16g I hope never to deal with creep again.
