Turbos are much more efficient, and in the end will make more top-end power. Supers are more usable for daily driving though. I love the sound of a turbo spooling up, but I hate turbo lag. I like my engines to be responsive.

You're right, twin turbos are very nice and have very little lag.

back in WWII Pratt&Whitney(or was it Wright? I can't remember) toyed around with a turbo-supercharger; it was basically both rolled into one - it was belt driven to eliminate lag, but when the exhaust was sufficient, it was run by turbine. not sure how it ever worked out, but seemed pretty interesting to me.

That'd be hot if they could work that out a turbo-supercharger. If you're ever bored you should try to find somethin on it and post it. I'm curious as to how it would work

There is still such thing as twin-charging... using a supercharger and turbo at the same time, kinda like twin turbo's. I remember reading in a issue of SCC quite a while ago that they were going to try and twin-charge a Mini Cooper S. That would be pretty sweet, all the response of a super with the high end power of a turbo.

this wasn't a supercharger plus turbo setup, it was actually(this is highly simplified) a turbo, with a belt attavhed to the compressor side; I'm assuming it had some sort of clutch to disengage the belt at higher rpm.

I don't really care.
Only ever drove one turbo before--a Daytona with a 5 speed. Kinda fun WHEN the turbo kicked in. Sure took awhile though.
Drove my Aunts 3800 S/C Regal. Good torque. Not much up high but I expect the engine has more to with that then the S/C alone.
So I don't care, either would do.

i like both and dislike both, i like supercharges but only centrifugal superchargers, not roots. centrfugal are easier to intercool/aftercool, and has a powerband of a turbo, with less lag. but it takes power to operate it.
turbo's are cool but dont like the heat build up, they get too hot. boost creap, and turbo lag. but they are verry upgradable and has more potential.
for allaround power, good for street/strip, supercharger all the way (vortec)

Lag and creep are features of poorly designed or improperly sized turbos, for street applications. The itsy bitsy turbon on my SRT makes 12psi at 2200 RPM. That's plenty quick to spin the tires. Big "drag" turbos will have some lag (on our small displacement 4 cylinder engines), but its a tradeoff. You can't make big power on small displacement engines without some sort of sacrifice.
Creep is caused when there isn't enough flow through the wastegate. Not all turbo systems creep.
I'm a turbo guy, but I'll be interested to see how much power we can squeeze out of the SS/SC setup.

I wish the Cobalt SS was t/c'ed

supercharger
"vanishing point" cop on radio- we have reason to believe its supercharged
haha that movies sick if you havent seen it its hard to find but definitley worth the effort ... you'll want to buy a challenger within the first five minutes
"mad max" i love it when he has the lever on his stick to engage the supercharger....you can't beat the noise they make
besides tv....i love superchargers that stick out of the hood on rearwheel drive cars.....though the cobalt isnt its a bit of an american muscle throwback and is def hotter then a turbo
performance wise no lag....

I've driven my friends SRT4 and the turbo is BADASS but i've also raced a few GTP's in my SVT Focus and hearing that SC scream is awesome! All i've gotta say is.....
STILL WAITING ON THE SCREAMER!!
I want my damn Cobalt SS/SC...

We plan on doing both!
we have developed and tuned a twincharger kit for the Cooper S and plan on one for the Cobalt SS as well. check out the link!

There's one produced for the Probes I'm going to pick up one day.

Mmmm... twincharging.
Mark - have you guys looked at ION Redlines at all yet? I'm wondering about the intercooler setup on these cars, as you probably know they have a laminova air-to-water setup integrated into the intake.
I'm wondering if this will be a limiting factor in the amount of power we can safely attain from these cars, and if we will have to go to FMIC if possible to do mods such as your twincharger system?
