How to hook this up?

[DCEPTCN]

I got one just like this the other day for $7 because I've exhausted the Buick fund for a while and needed something cheap. If it sucks, heck I only paid $7! Will it work on these cars? Now, it doesn't have any instructions with it and I would hate to hook it up backwards or something and have a problem, so I thought I'd ask first. Does/has anybody run one of these and how does it hook up? Thanks.

Do a google search for manual boost controller, install should be very similar to a number of units out there, including some tother homemade ones. You can also search here for the unit that (I believe) sinful6 was selling awhile ago as it was almost the same.

I think there's a couple of guys in Maine that run them.

Then again they figured it out on their own.

It's basically backwards of what the boost control solenoid does. The solenoid vents to atmosphere; this is hooked INLINE from the boost/vacuum source, to the wastegate actuator.

When boost comes on, at the point the boost pressure exceeds the pressure adjustment on the ballspring, the ball will move back, allowing pressure to reach the actuator. Since the air chamber in the actuator is a closed system, if you look closely at your ball spring assembly, you likely will see a small bleeder hole if it's like mine- this is so that the pressure can bleed back out during the times when the ball valve has closed. You shouldn't let this hole get plugged, it will interfere with operation (not a disaster, just less inclined to hold boost).

I found adding mine that boost seemed to come up faster than with the bleeder valve, but I also found that there was a tendency for boost to overshoot what I set it at, then settle back, so I run it a little lower than I intend to avoid knock when I punch it. This effect would likely become augmented if the valve got dirty/sticky.

Oh....make sure you don't get it BACKWARDS! The actuator would never receive any pressure, and you'd get overboost.

One more tip!!

Go to an autoparts/paint store and get an HLVP spray gun regulator. The regulator installs between this and the turbo, I use the boost contorller to adjust spoolup and the regulator to limit boost

I need to hear more about that - I'm not sure what you mean or how it works, but I'm interested. Do you mean

vacuum-and-turbo->regulator->boostvalve->actuator?

Or is it somehow retaining the stock piping?

Ball and spring design

Yours must be a ball and spring type design for this to work. I looked into these norgren valves but the relief will take 71 DAYS to get shipped from Norgren. http://www.autospeed.com/cms/A_0670/article.html?popularArticle

This person has some good info on how the system works.

 

[kgouldsk]

That's a good article. I may just look into sourcing a regulator here - I'm presuming the self releasing ones are common.

Let me know if you find any in the US. I'd rather have a higher quality one than the brass fitting kind.

How should I adjust my threaded rod on my car when I install this thing?
