BerinG:

The tunes are adaptive. You can add/remove timing at all sorts of temperatures. Build a tune that will run good hot, and you'll be safe when cold (though you can tune in a bit more performance at low temps).

That's the GREAT thing about the EECV

SLIP STREAM SVT:

well, you're not taking into account 2 things;
1) the extra load on the engine from a supercharger that turns 3 revolutions for every single revolution of the crank + driveshaft parasitic loss.

2) the fact that the vortech supercharger 'mists' oil into it's drive assembly. Misting doesn't happen when motoroil is thick as molasses.

I'm running 0w oil, and the car does start down to -30 (with windchill)... but not happily. You're not even sure the supercharger is running until the car is warmed up and the whistling comes back... but it appears to run. Only time will tell if i'm doing real damage to the supercharger, but right now, things seem positive.

Would I do the vortech again if given the chance? I dunno.. if it was a competent shop, maybe, with 2 big differences:

1) move the battery to the back
2) move the filter up a little bit.. maybe to where the battery tray was, with a splash shield.

There's nothing wrong with being worried about the daily driveability of an aftermarket component (like superchargers). Some will pass it off as unecessary worry, but would you like to spend $4000 on something for your daily driver that's going to leave you stranded in the cold back country?
