"Supercharging increases air density and significantly increases power on an otherwise stock engine. In short, supercharging makes a V-6 perform like a V-8 and makes a small block V-8 perform like a big block V-8. OEM manufacturers like Ford, GM, Mazda, Mercedes, and Jaguar offer factory installed superchargers on several models due to the tremendous benefits. Our supercharger systems offer more torque and horsepower per dollar than any other single engine modification. Most other modifications available require specific matched parts, in-depth tuning, are not smog legal, and won't produce the performance gains you'll receive from just the simple addition of a supercharger system"

While spool-up may take a bit of performance off the line, once things get up to speed the performance is much better and takes less of a toll on engine life. With a supercharger they tend to lessen the life of the engine, especially in the crankshaft and the bearings.
Oh, and the reason you don't see turbo cars in Top Fuel is because they ARE NOT ALLOWED by the rulebook.

Supercharger owns a turbocharger any day my friend..
You don't see top fuel cars running turbocharers, they are either blown or supercharged.
Actually the reason why TopFuel rails don't use turbos is because they're not allowed to, as per the rules. If you look at any class that allows BOTH turbo and supercharger power adders, the turbocharged cars will almost always be faster (ie. NMCA). It's simple physics, really -- turbos are more efficient, period.

it depends alot on your engine type, how it takes to either the super or the turbo. what other internals you have, and what type of power band you are looking for. read up on it a good bit before deciding.
as a side note, to get the maximum efficiency out of any forced induction, you should look at changing some other things in your car. exhaust system, fuel injectors, etc... there's alot that goes into a proper a blower setup, if you just slap something on there and don't build your engine around it you're cheating yourself. ;]
Turbo is used in high RPM's
Superchargers are always on
Depends what turbo & supercharger you're comparing. It's not unusual at all for a properly sized turbo to spool up quicker and make a ton more power than say, a Vortech supercharger for any given engine.

That's because they're not allowed to run turbochargers in top fuel, not because superchargers are better
Superchargers have more parasitic loss than a turbo, in other words it takes more power to turn the supercharger than it does a turbocharger. Turbochargers run off of exhaust heat & pressure, superchargers off of a pulley from the crankshaft.
Turbochargers only put pressure on the engine when you really step on the gas beyond normal acceleration and create boost, a supercharger will stress the engine at all times because it creates boost relative to engine RPM. Less stress on the engine during normal driving is a good thing, so the turbo wins out in that respect.
But a turbocharger also has special requirements, such as letting the engine idle for a while after it's been run at high speeds, so the turbine has time to wind down and you don't cut off the oil supply while it's still spinning. Turning off the engine suddenly after having the turbo spool up - just once - could destroy the turbocharger.
If you have unlimited funds and are going to pay someone knowledgeable to install it, you'll probably be much happier with a turbo if its set up properly. If you don't have the money or the desire to be so careful with the engine maintainence, a supercharger would probably be a better option. However I'll be honest and say that most people who don't know this sort of thing and dive into either option end up with a blown engine in a few months regardless from misuse. With either option look into getting an oil cooler and if possible an intercooler, it helps with engine reliability and can give more power.
they both have strengths and weaknesses. depends on the car your putting one on. I personally like turbos better. most places mod cars with turbos, not superchargers. I cant think of many popular supercharged cars. Ford SVT Cobra, Ford GT... um, can't think of any others off hand.

I am not looking at aftermarket add on's , I am about to get a supercharged Jag XKR convertible. Just wanted some feedback from people with experience in eighter method

A turbocharged car would left at the line.. They run it due to rules yes, but they run it because of the shot. After that it's all air/fuel compression..
A factory car with a turbocharger and one with a supercharger, the supercharged car will eats its ass alive.. I have seen it happen all to many times. Pound for pound and price, superchargers are the leaders of the pack.

That's not what the numbers and recordbooks say. All indicators (ie. national titles, ET's, trap speed records) all say that when it comes to turbo vs. superchargers, turbos win out every time. Where do you get your info from?
The Supercharger is nicer around town because of the instant throttle response. Also more fun in the rain and easier to control slides when the engine is so snappy feeling.
The Turbocharger is nicer on the highway and for big horsepower. It's easy to turn up/down the boost for cruising or the racetrack. The turbo doesn't produce power down low, but for the most part, when do you need power down low? around town.
City driving = supercharger
Highway/racing = turbocharger
At least, in the opinion of someone who owns both...
One is belt driven and pushes air into the intake and the other takes its pressure from the exhaust gases. Well that?s how I remember it.
It really depends what your application is. Be careful though, if you already have an engine with a high compression? you really want to be careful. Same goes for NOS

Listen to Cheesefrog man, he knows his shit. A Supercharged Supra for example, would get destroyed by a Turbo Supra.
Same goes for a Supercharged Mustang VS Turbo Mustang
Same goes for a Supercharged Viper VS Turbo Viper
and on, and on, and on....
They TheDoc, do you own a supercharged or turbocharged car, or are you merely talking out of what you have read in magazines?

I only read golf mags these days
I had a 91 stang with a whipple charger..
Currently have a 1990 Chevy Silverado that is waiting for me to get some more time. Has about $50k into it but still has the stock motor.. I don't have a place to work on it anymore.. It's just chillin at my Dad's house waiting on me to move out to Colorado.
Go for an all aluminum 350 small block. All roller (crane) with eagle pistons and rods. All this NOS crap and what not... no good if your bottom end (crank shaft and so forth) is weak. Get good bearings in the bottom, and one of those oil scrapers in the oil pan to keep enough oil everywhere.
It depends of wich car you want to use ... and what else you got under the hood ...
The turbo provides virtually an unlmited ammount of horses ... as much as your exhaust air flow produces (makes the turbin spins faster from what I understand) ...
But with turbo you get "lag" and stuff ... just get good advice from somebody who really knows their stuff ... not gfyers ;)
I rebooted, deleted temp files, history, cookies and everything...still cannot view the news clip. All I see is that fucking gay ass music video from "Rick Roll". Anyone else have a different link to the news clip?
Actually, one of those 502 crate engines would also be a good solution and deliver enough power. They are really nice. Not sure how the bottom end is in those, but they got 502 HP
My Turbo Supra did 737 to the rear wheels, nobody has bothered to supercharge a Supra
The Supercharged S2000 did 350 to the rear wheels, and turbo S2000s typically put out far higher numbers.
A Turbo Mustang, with equal drivers, chassis, and tires, with a proper tune, would kill a whipple Mustang.
Honestly, I don't remember exactly anymore.. I think it was up around the 400 range. It was my fav by far though and one day I will do another one but I will go with a small block 400 this time. Young and dumb the first round.
I'm much more into doing the car up now.. Had a 2000 eclipse with more into it than I can list but didn't do much to the motor. Right about $8k in the system, still have the system sitting my garage waiting on my truck.
My truck, old picture it looks a bit different now.
As stated before, it really is a matter of what you want. Now those quoting numbers, remember, turbos require alot of internal strengthening before running properly (i.e. upgraded camshafts, cam gears, valve springs, retainers, aluminum gaskets, port & polish, angled valve jobs, etc...) before you can run it without worrying about detonation. Also you have to take into consideration the amount of maintanence a turbo requires. So dollar for dollar, supercharger will be the better bet. The power is linear, this means at idle you are running about 3-4 psi. Turbos run 0 psi at idle and spool slower, power generally comes at about the 5500 rpm range then the power rules. So the turbo will be playing catch up in the race. Superchargers are not made for top end power (this is where the turbo will gain and rule) but more for low end torque and power. Means at the light you will spank the turbo but at the end the turbo will eat you. Although it is possible to bolt on both to a stock engine, the turbo will cause the engine to detonate under the all the added induction it is receiving. Thus the addition of stronger internals. You have to also properly tune both for maximum efficiency. Compressions plays a major role here so make sure to keep this in mind. Try adding a stroker kit (no pun intended) and then base your decision on the final numbers and where you would like the power. Nuff said.
A turbo will make more power in the end.. But a supercharger will deliver it faster.. Newer multi turbo setups are blowing (pun intended) superchargers away but it will be awhile before any real racers make the switch.. I mean, alot of still use carburators!!
Don't forget, you can run anti-lag systems on turbo cars and launch your car from a stop under boost. My Supra can build 15 psi for launching using the 2-step rev limiter built into the AEM engine management system.
