Of course it would make it less reliable, but the idea was to have it linked to a button not make it last forever 
supercharger?

MR2 supercharger
Clutch activated superchargers have been used in OEM applications.
Did you already know that, or did you learn that from reading the comments on youtube of the video clip I posted?

A switchable supercharger would be ideal for my needs; I spend a lot of time not accelerating, not running at WOT, and being happy about my little fuel sipper. The turbo is more than adequate for accelerating or maintaining speed on the uphills. Having available additional power that cost even more fuel, but which would only get switched on every now and then, would be great. Sort of like NO2 and Water/Methane, and like turning the TC/SC off.
If the system isn't engaged often, would that make the clutch driven nature of it last longer, or are you saying that idling it would still be damaging?

Why has an electric pro charger not entered this discussion?
Zero parasitic power loss or wear when not engaged.
Honestly, I think the idea of adding a second charger in combination with the stock turbo would be a silly waste of resources. The thing starts boosting at 1,800 rpm.
The only reason to pursue staged charging for out application would be if you go oversized with the main turbo, and need to assist it into it's higher boost threshold.

I have known that. I researched the idea years ago for a project that never happened. I believe both of those are equivilent to a M45, which is way to small for what I had been wanting to do. I can across a few other applications, but I forget what they were.
Preloader, that is an awesome idea. Would open up a lot of packaging options and remove parasitic drain for the majority of the time.

I think my beef is power off the line is completely useless for real world purposes. People who like to burn rubber showing off how horrible their traction is like things like that.
Now I'll admit the 1.4 could use a little more oomph off the line, especially when you're stopped on a hill with the A/C going on a hot day, but it gets by. I wouldn't waste space or money on a supercharger to solve it.

My Cavalier had a turbo that would hit full pressure (10 PSI) by 2500 RPM and it was just a smoke show in first and second if I wasnt careful. Low end power is great if you can actually use it. Leaving rubber on the road on a whim in first and second isnt gets old fast.

I don't know. You have to reach forward and press the button and then reach forward and press it again. On a scale of 0 to 10 10 being the hardest I'd say it scores between a 0 and 1.
Why do you ask?
I've owned 6 vehicles before the Sonic. 86 tbird, 87 grandprix, 92 c2500 pickup, 95 lumina, 06 grandprix, 06 vue.
The Sonic is the only one I've ever even had to consider turning the A/C off to take off from a stop. I think that's the point, not how hard it is to push a button.
Yes, there is still plenty of liquid boiling in the evaporator but the second you turn the compressor off the evaporator pressure starts rising, especially on a 90-100F day. You will notice it warming up immediately.
All of that said, I don't think I made that big of a deal out of it. It's just one of the things I dislike about my Sonic is all. I'd still buy another one and I don't want it to have a supercharger.

In all honesty I can't see it being useful either. There are plenty of mods that will give u a little more off the line without spending super/pro/turbo kind of money. Unless ur gonna go real fast, add horses and torque in other areas. Maybe lighten up the car. If ur still not satisfied but a sti

I agree, except for trying to satiate with a Subaru.
A much simpler/cheaper approach is a small nitrous shot programmed to engage at the lower half of the powerband.

This is the 3rd car I've owned were I benefit from toggling the A/C off/on for better acceleration. Down here in the lower working class it's pretty common.
I think almost all of them benefit from it, but the Sonic is the first I've had that damn near needs it if you're on a hill.
Don't give me that lower working class crap, I'm poorer than you.

Doesn't the compressor shut off automatically at WOT?
I know others have already said this, but it's also in use in non-OEM applications. Blitz makes a S/C system for the Echo/Yaris/xA/xB that is exactly this, it's even variable as to how much slip the clutch will have to allow you to run different level of boost on the fly. Buddy of mine has one is his xB, gets it close to the Sonic stock, but doesn't have a lot of headroom above that without swapping out the clutch pulley for a static smaller size one.
