Ok, ONE. It's still off the crank, and it's still a PARASITIC DRAG. Now show me a dynochart of a whiple on a I4 engine.

Listen to what your saying....
You can turn the screws on a SC with your HAND. How much PARASITIC DRAG do you think that is? 2hp? 5hp at the MOST? And you get HOW MUCH in return?? Lets see, more power than stock and NO LAG??? Not to mention not having to plumb in an intercooler?
Read my first post about what I think about PARASITIC DRAG 
Like I said before, all those drag cars that they worry about every little HP and pound of weight dont seem to mind all this parisitic drag, why is it even a point? Go ask the guys with the '03 Cobras how their car even runs with all that DRAG.......
If your whining about parasitic drag, then you must be running out of things to gripe about.
Your alternator is off the crank, you should take that off cause its a parasitic drag too.
My whole point is to shut up those of you that think a SC isnt as good or better than a turbo. Deal with it.

How is it a parasitic drag when it takes almost nothing, yet gives so much more power??

the more air that the blower moves, the more hp it takes to spin it!
so it may take 3hp to spin it at idle when its boosting less than 1psi, but may take 25 hp to spin it when its boosting 15psi, thus making alot more power than it uses!

You have got to be kidding me...... A blower gives boost depending on how fast you have it set to turn, thats why different size pulleys are used. Smaller pully=SC turning faster=more boost.
Really I didn't know that. Still not full boost.

Its all in the design.
I have 2 mechanics here right now laughing at this post, total experience in building performance V8s is about 30 years. Guess you know more than they do. I had to tell them to see this post cause I knew they would get a kick out of it. I guess my experience building 2 SC motors are a mute point here, too 
Get this straignt- An engine can have equal output whether SCed or turbo charged..ITS ALL IN THE DESIGN.
Wow, that's same great info. So they have experience with V8s, what were we discussing here? Umm 4cyls,, wow how relevant. No **** an engine can have equal output, but I GUARANTEE, the engine in discussion is more able to use HIGH power made by a GOOD turbo design than a GOOD supercharger design.
But since you're so great at this stuff, I wish we could get someone to fund a little project for us, to see who can get the most power outta a zetec, you with a supercharger, me with a turbo.... 
All hail the boost god.............Kremit

And thinkmoto turbo lag is not defined as the period of RPM where you don't have boost... but you probably can't understand that... we've already seen how smart you are.
kremit seriously now do you think anyone will listen to you and make a sound decision from what you say????
No, but they should.
But, hey, ya'll should all go slap s/c's on zetecs, and I'll put a turbo on mine.  Because of course SC's are soooooooo much better.

I already have a turbo, so somebody just needs to get a supercharger.  I was just reading an article about the new Cobra, speak of the devil. They did a comparison with a new Cobra vs a new Mach 1 with a vortech. The vortech'd Mach 1 out performed the 03 Cobra in virtually every respect, though that's understandible since the Mach is lighter and had higher compression. They did do a test where the measured how much boost they had at what rpm. Don't remember the Mach1 but the Cobra had 7psi at 2250rpms and 9psi around 5000. That surprised me, I didn't expect it to have that much boost at that low a rpm. I only have around 4-5psi at 2250 and I don't get 7psi til 2500rpm, but I get 9psi by 2800rpms. It is nice to have a discussion like this, even though we're so far off the main topic. The zetec sections are usually pretty slow. I'd like to post more, but I'm freezing right now and it's way past my bed time, got to wake up early tomorrow. I will post more later on the subject, including the scenario's when a supercharger would out "perform" a turbo.
