Turbo vs Supercharger

I'm investgating to get a new turbo or supercharger for my NA Tiburon and I wanted to be clear on some things. (Just to ease my mind)

1) What's the differance between a Turbo and Supercharger?
2) Which one gives a greater differance in horsepower
3) How is the gas mileage affected by installing either or?


Thanks for your help.

this has been covered quite a few times, and that's just in the short time I've been here.
not to be mean, but try a forum search.
Just in case you are too lazy, turbo is better, mileage will drop slightly, but will go down more, because you will have your foot on the floor more often.

thanks for the compliment j/k

No I'm not lazy. I just wanted a current direct/acurate information thx.

gotcha.

Forced induction technology has not changed very much. Go search.

You guys seem to be misunderstanding the reason I asked. I already know the differenaces, but I wanted to know what you guys thought just to make sure my facts were straight. If you weren't going to help me why did you post? lol

oh, in THAT case.
deffinitely a turbo because they are more efficient, tuneable, and upgradeable (just swap the impeller).
The mileage won't change at cruising RPM's (around town, etc). and can actually improve.
at open throttle, it will suffer, but the gain in power is way worth it.
difference is only the way the compresser is powered.
super = belt driven
turbo = exhaust driven.

alright that's what I'm talking about for help LOL

When you mean suffer, are we talking about like from 20mpg to 16 mph or something smaller?

yeah, not too bad.
maybe 20% at most.

Yes so either 20 to 16
or 21 to 16.8. Meh, not too bad
Unless Hyundai found away around it.

Now what would the mileage be with a supercharger?

bout the same.
at the most, 25 instead of 20.

hmm so then I can see your point that a turbo would a better by. Any other points or advice you have?

turbo is quiter (superchargers make a whining noise)
only bad thing is that you have to let the car warm up/cool down to protect the turbo bearings.

How forced induction works. Includes Turbochargers, Roots Blower, Centrifugal blowers, and Nitrous oxide.

Eh, I wouldn't really say N2O is FI.

1. What's the differance between a Turbo and Supercharger?

A turbo-charger is driven off the exhaust, which is free power, but you will have spool time (turbo lag) where it takes a small amount of time for the exhaust gases to spin the impeller. A super-charger is belt driven off the engine. This uses power from the engine to run, much like and A/C compressor. This also makes a super-charger's boost instant.

2. Which one gives a greater differance in horsepower?

I would say that the turbo since it has no parasitic loss like a super does. Also a turbo is much easier to get more power out of and will be more efficient.

3. How is the gas mileage affected by installing either or?

As long as you’re not throttle happy you shouldn't loose much of your mileage with the turbo. Just remember that it will only boost while under load. You will loose a lot more mileage with a super-charger since you're always boosting and the super is always using power.

Well it does, technically, force more oxygen into the cylinders.

It increases the oxygen % in the air, but it doesn't force in more molecues of O2.

That's true.

Well the reason I posted it up as FI is because N2O really doesn't appear in the natural atmospheric world. While you can use N2O to increase power in NA applications, N2O can also be used in greater function in an FI application.

The addition of N2O in an intake charge will lower the charge temperatures as well as create a boost on power.

Depending on the type of supercharger is how much parasitic loss is apparent as well as ease of installation. Most roots blower are able to be bolted on with no other modifications and can increase power up to 50%.

The turbo does not have a parasitic loss in the same manner a supercharger does, but it is still a restriction of the exhaust until the turbo begins to spool. I have seen a Supra dyno sheet that maxed out at 1137 whp at 8000 RPM, with an increase of 600 whp between 6500 and 7500 RPM. But the car only made 250 whp up to 5000 RPM. That car should have been able to make more power while not under boost.

You contradicted yourself with your second sentence.

I meant the atmosphere does not contain nitrous. It must be injected. Better?

Why not give it its own classification? All 3 fall under "power adders": supercharging, turbocharging, and nitrous.

whoa thats some crazy lag. wat turbo did he have, t88?

basically it comes down to this

turbo: very practical for streetable cars, makes decent power out of waste.

Super: you need this if your wanting some crazy boost and big hp. not as effective for japanese fourbangers as it is for domestic v8s

WHAT THE HELL IS THT A YELOW SPACE SHIP!!!!!
jk
thats a good question, and it depends what you want. turbochargers are undeniably far more efficient, however lag is the drawback unless you are going to run supplamental turbochargers (1 large and 1 small). thats rarely an option though due to price, space under the hood, and all that frigen plumbing. superchargers are instant power, but like anything belt driven (ie. air conditioner, mechanical fans) it puts resistance on the engine. id recomend a turbo, preferably one with ceramic ball bearings. (ceramis spools faster requires less stall speed, and lasts much longer). hope this helps

one more thing id like to add. despite what some people are saying turbochargers were originally intended and used to increase gas milage.any car will get BETTER gas milage with a turbo pushing low boost than it would with out a turbo.that is of course under NORMAL driving conditions. that rule of course goes out the window if you like to keep your foot glued to the floor. i tested the thery by setting the wastegate on my gn to 0. not only was it slow as death, but my gas milage went WAY down. and its tough to argue with stock gn's 3,000 lbs, 12-13 et. and 26 mpg. are there any non turbo 13 second heavyweights with that mpg? im not saying their aren't (but i cant think of one) if their are they are about 15 or so years of technology newer. food for thought

When youre racing dont turbos take a while to kick in?
Arent they bad for drag racing?
