build my own boost controller...

Todd, BTW, I did tried both set up & found
that in my case regulator before reliaboost
work much better. Lastly, are you using
stock or aftermarket wastegate ? That would
make a difference due to the spring tension
in the wastegate. In anycase, be gentle with
the settings.

Ok, I will try that set up.
So your running the Reliaboost as the relief valve?
As that may be why you saw a difference instead of using the relief valve mentioned in the article.
I have a GURU rebuilt, so the spring is improved from stock.

Whoo-hoo... 25psi musta felt good for that brief moment!
I so worry about high boost... dont exactly want to come back down from it. Must be kinda like heroine.
had a 240sx with a turbo sr20det... got to the point where i was daily driving it with 28+psi. Blowing stuff like crazy, but (at the time) a cheap engine to replace.

I'm seeing 1 bar at 3000 rpm but that's
with a slightly leaking exhaust. Going
over to an Apexi AVCR soon cause I'm
getting one for free. BTW, I'm running
a GT25TO4S turbo.

Well, when I was taking it apart to try reversing regulator and relief, as Jchen suggested, I tried adjusting the regulator and blowing and found that the body itself was not tight and was leaking. So I tightened it and no more leak. I will try it again on the car soon. Hopefully that was the problem.
Jchen, you are useing this same setup except:
The reliaboost as the relief
And you run the regulator first, then the relief
Correct?

Hey guys. I don't own an 951 (yet) but have been following this post. I started messing around with turbo dodges a few years ago to learn how to blow up engines the cheap way. I'm finally through the "boost till it blows" phase and am approaching the level of maturity required to own/tune a car thats not quite so cheap to replace engines in (try $300 for a good used shortblock on the turbo dodges).
Anyway, I thought I'd share a couple turbo dodge boost control links...
http://www.thedodgegarage.com/turbo_boost.html
http://www.xmission.com/~dempsey/perform/
they cover many of the same ideas you guys are talking about here. They also go into some designs of staged boost control, which is basically just multiple boost controllers at different settings, selected via soleniods. The other good thing is everything they design is CHEAP.
Just thought some of it might be interesting reading for you guys. I don't think they have any new secrets, just a little more discussion on the topic.
Also, J Chen... did you ever finish/evaluate that cheap DIY anti-lag device I posted about back in July '04?

Chen: Are you still running with the Audi Controller? And did you say you used the reliaboost in place of the other regulator?

Oh sorry, the relief.
And in what order are you running them? relief first then regulator?
I tried running jsut the Reliaboost with the check valve and did not notice any difference.
Right now I have the relief and then the Reliaboost as the regulator and not noticing much difference.
