boost creep-please help

[91screamineagle]

I'm fairly new to the DSM world and this may sound stupid but, will a slipping clutch cause boost creep? I set my boost controller to about 14 psi and throughout the rpm range, it reaches in excess of 20 psi sometimes. Please let me know what you think.

no slipping the clutch will not cause creep.

So I should have just had the turbo ported when I ordered the stupid thing. I heard the EVO III's are bad for it but I figured I could still run relatively stock boost with no problems, but I guess I was wrong. Thanks for the input, I appreciate it.

The lower you try to set your boost level, the worse the creep.

So should I set my boost higher and upgrade my fuel? I just dont want to hurt my new engine with all that boost b/c it's not built much and I don't want to blow it.

You could also get the boost creep elimination kit from www.dpconcepts.com. Saves a LOT of hassle in taking the turbo off again and porting it out.

Yes, that is one way to get around creep but usually requires other supporting mods to support the fuel mods and higher boost level, how high you're creeping to also plays a role as well. 14b isn't exactly the turbo you would want to run 24psi with on a DD even if you have proper tuning and fuel mods. The real fixes to boost creep are porting, like the link provided, or external wastegate.

i did a little porting to, turned the boost up to 17psi and it holds fine. i have the fuel mods done tho. http://www.dsmtuners.com/forums/showthread.php?t=191447&page=2&pp=25

hope this helps you

So if I want to go with an external WG, I have to get a different turbo like a T3, right? I love my 16G, as far as spool up and power but I just spent alot of $ on it and I can't really afford a whole new setup.

No, an external wastegate is usually mounted on the exhaust manifold or the O2 housing.

 

[91screamineagle]

but what about my internal wastegate? Do I just leave it unhooked?

You weld it shut for a manifold mount, remove the flapper and open up the wastegate passage for an O2 mount. The better option of the two would be a manifold mount as an O2 mounted WG will most likely still requires the same amount of porting as the tech article when keeping the internal wastegate. IMO, porting is your best option since it costs little to none, keeps your car quiet and stock looking as well as a great opportunity to get intimate with your turbo system.

Thanks for the help. I appreciate it.

You're welcome.

I love how I keep getting totally ignored on creep threads. DPConcepts provides a $30 kit that takes about 15 mins to install that is GUARANTEED to stop boost creep. Why would waste all this time and effort on externals and porting (which can actually hurt flow if not down correctly), when you can use this easy kit?

Because if you take a die grinder and a carbide burr to the back of where the wastegate flapper hits the turbine housing, you can port enough material off so the flapper can open 90*. And it takes about five minutes to do. Porting has been done for years with positive results. And it's fun, at that.

All that kit does is move the actuator arm closer to the flapper arm pivot point. JB Weld could do that for $5.
