Granted weather or not he does this, I think it's important to get the whole SVT vs regular Zetec discussion in the open, if it hasn't been done already. Here's a good thread with some more info on Turbo's vs SC's. The main poster to look for is P-51. He's one of the smartest guys on the Focaljet. He's custom installed his own turbo kit, was one of the first guys in N. America to buy the Pectel Focus kit and tune it himself, and he's a former Ford Engineer. He says it all right here: http://corner-carvers.com/forums/showthread.php?s=0964030ae99abf694fa8f4f7fce55009&postid=157113#post157113

But you didn't have the benefit of my expertise then.   
And I believe the term you were looking for is "boost threshold". It's mentioned in the link I posted.
P.S. Your in Ontario? Aren't insurance rates sky high there, especially if you got mods? I hear they're denying coverage after the fact even if all you got is lowering springs. Or is that a different part of Canada?

www.car-part.comDozens of SVT contour engines from totalled cars or rebuilt. Most expensive was $2500, most were 1100 A(1460 C), not 6K! Same tranny, new compy.  In Nova Scotia I found 2 more in Ontario. But that's it. Most in Usa.

Also a SC, because it's tied to the crank, is a parasitic drag on the engine
*Not Zetec related but I dont care*
Everytime I hear this I laugh my ass off.
Part of my truck buildup will include a 4-71 blower on my slightly modded V8. Pushing a small amount of boost, (Im after the look and sound more than brutal power) I can rely on getting 75 or more HP and massive torque.
Im really gonna be hurting on that small loss of power to turn the blower when Im getting so much more power in return.......
Guess all those race engines with a SC that I see on the track must really be hurting too.
And on the topic of less torque from the SCs, there are different designs of the SC itself, some will give as much as a turbo setup, and some are made for top end power.
IMO, while both are good for power, I would rather have the instant pull of a SC off idle than wait for a turbo. Im a big fan of low-end torque.
rant off....

Let's see, no insurance rates are not super high here I'm only paying about 2100 for the year,which is good for the type of driver my record shows(2 speeding tickets)and that's full coverage. Since everybody has there own opinion on this FSVT engine and what a bad idea it is to buy new plus put s/c on it, I think I'll spend the 12000 on building a bullet proof turbo zetec. I think I was taking the easy wayout, and since I do all the work on my car myself (with the help of dad and his friends hoist)and it's my daily driver I didn't want to not have a car for a while that was the best way to go I thought so in the intrest of making all you happy I will turbo my zetec.

INCORRECT. Because the S/C is crank driven it will not reach full boost until a certain RPM,, you don't just sit a supercharge on the intake and expect it to instantly make boost. Ask anyone with a supercharger (plenty of duratec owners on here) I believe the vortech for the duratec doesn't reach full boost until over 3k rpm. You can easily setup a turbo to reach full boost at the same place a s/c does or before. Not all turbos have lag, they have something else, can't remember what it's called, which is the point before they reach full boost but it is NOT LAG. A small turbo with a good setup will not have any lag. And as low compression is good for s/c AND turbo. High compression is good for n/a and nitrous... Why is this even being discussed,, you're not even gonna do it anyways.
Actually a S/C has it's turbine spinning all the time in sync with the engine, cutting the lag time way way down. You are right about the super charger not reaching full boost until a certain RPM because of the rate of speed of the pulleys, but the same applies for a turbo. Since the turbo turbine is spun by exhaust gasses, you will also need to reach a certain RPM, or a certain amount of exhaust pressure to spin the turbine to achieve full boost. Any turbo setup will have more lag than a S/C just for the fact that it's not constantly spinning like a S/C. Unless you weld your exhaust exit(s) closed, which I wouldnt recommend.
Thanks for attending class, you've just been schooled
