Two Quick Boost Actuator Q's...
Okay, so I literally have tools in hand and I'm about to try the boost actuator mod that some have done and everyone has atleast heard about. But before I do, I had two quick questions I was hoping you guys could help me with...
#1: Is the front bolt the only one with an adjustable slot (i.e. I don't have to pay attention to where the back one was originally adjusted to)?
#2: On Chuck's webpage where I got most of the info from, he said that the way he first adjusted it it built boost at 80mph with just the slightest touch of the throttle, so he turned it down some. I guess I just don't see how is building boost is bad?
Any tips, tricks, comments, or advice? Thanks, later...

I didn't see any one answer quickly, so I'll try since you have tools in hand.
I have an 01 but should be the same.
The answer to #1 is Yes
#2 I think the issue is that at 80 you need to push down on the throttle to maintain the speed, at least for me it was. The blower being at full bypass will be most efficient in terms of fuel economy according to what I have read.

See #7
I have had several blown cars and this is the first blown engine with a bypass. Kind of different! On those configurations any movement of the throttle produced boost. So I guess I agree with you!

Here is more information from my Ford Factory Service Shop CD.
A little off of the subject....
"Supercharger Bypass Vacuum Solenoid and Actuator
The Supercharger Bypass Vacuum Solenoid will bleed off boost during sudden throttle closing. This prevents damage that can occur if the throttle is quickly closed while the engine is still under heavy boost. The solenoid is located on the upper LH side of the engine. The solenoid uses engine vacuum to operate a actuator and linkage that connects to the pressure bleed off valve. The actuator is located near the solenoid and is connected to it by a vacuum line."
"At partial-throttle opening or when vacuum is present in the intake system, a vacuum-controlled bypass valve reroutes some discharged air from the supercharger back through the intake plenum. This prevents the supercharger from cavitating, causing reduced performance, increased temperatures, and poor economy."

MXRacer,
The front bolt has a fairly large slot. The back moves a little. Before you mess with it (my opinion) I'd get a Sharpie pen and outline the edge of the actuator where it contacts the S/C. I did and was REALLY glad I did so that I would have a point of reference.
What David posted was very interesting. I'd never seen that before. I can also say that on mine , depending on where the actuator was tightened down, there was a noticeable effect on 0-60 times with the G-Tech. Don't know why, but it did. Just mark your starting point and experiment - it shouldn't hurt it but don't go to extremes. The factory is very close and it seems to be a really, really fine adjustment IMO.
