Basically turbos use exhaust to make hp and supercharger uses hp to make hp. Turbos are basically air and exhaust driven where as superchargers are belt driven, so I would put the exhaust to good use, and make some hp rather than just to make noise coming out of your car but it all depends on the driver. Turbos require a little more maintance and are more pricey than superchargers.

is it possible to install a supercharger adn a turbo charger??? because a supercharger is installed behind the fuel rail isnt it??? and the turbo is installed somewhere along the exhaust/ intake system??? i donno im just going out on a limb with this stuff...

its entirely possible to do supercharger and turbo. but its stupid if you ask me. the only good thing is that it will sorta act like a twin turbo setup, where you have a small turbo for low end operation and a big turbo for high end... but the only problem i see, the supercharger becomes more of an air flow restriction towards high end where the boost from the turbo goes higher then superchargers boost. and a common misconception, if a supercharger is pushing 6psi and your turbo is pushing 10, you don't get 16 psi. the boost you get is which ever is pushing out the most at what ever RPM you are at. they don't add together.

the article from ford vs chevy seems to make sc sound like the superior option without just out and saying it. i know it can't be that cut and dry since turbo is such a popular option. i have to admit that the most attractive feature of the S/C is what the site claimed to be easier to set up and requiring less modification.

anyone have some input regarding this? thanks

Re: What is turbo? What is a super charger?

ok then i have heard about a pro-charger, a belt driven and air inducted turbo. what the **** is this. it not only makes not a lot of sense but i want to know y you couldnt just do one or the other. y have the best of both worlds in this case

cuz there's no application for our car, thats why no one uses one..

a pro-charger is a supercharger, since its driven directly off the motor via a shaft instead of the exhaust gases like a turbo, except instead of the traditional roots (screw) type supercharger, the belt/pulley is attached to basically what looks exactly like a compressor housing and wheel of a turbo, so there's no turbo lag.

Re: What is turbo? What is a super charger?

what about a dexi charger, or something called something like something like that. I ran into a guy who had a mustang, he said it was like a supercharger, but with more computer control to obtain the most horsepower at each different level of rpm, if that makes any sense at all.

Re: What is turbo? What is a super charger?

^imo twin turbo is good but not as efficient as a single turbo. twin turbos dont exactly spool at the exact same rate and do cause different boost levels to occur.

turbo has a two sides hot and cold which contain fins on each side attached to a rotating shaft. the exhaust side spins one side to make the compressor side suck in air through an inlet then pushes it out to the rest of the system. as rpms increase so does the amount of exhaust pressure to spin the hot side of the turbine. this cause the compressor side to spin faster... this is called spool. the air that is coming out of the compressor side is pressurized and considerable hot ... needing something to cool it before it is forced into the intake of the motor. that is what a intercooler is for. pressurized air flows through the intercooler which gets cooled by the forward motion in which is moving to cool the air inside of it through its fins. once full boost is reach it remains constant through the rest of the rpm band.

supercharger has a compressor side that is spun by a pulley. by changing the size of the pulley you can manipulate the amount of boost. this pulley is driven by the crank pulley. as the pulleys rpm increase so does the boost. so you do not hit max boost until you are at the end of your rpm range. for example 3 thousand rpm on a 6psi pulley would be close to 1.75 psi.. just and example. you can use intercoolers to cool the air from a supercharger but you will lose pressure in doing so.

high horsepower one should go turbo. something that you just want to slap on for 50more hp then go supercharger.

as far as all this talk about supercharger and turbo... yes it has been done and yes i ve seen the car drive. it was on a scion tc at last years hot import nights show here in ny. the points that i read on this post are valid due to the restrictions of the super being in the way of flow of the turbo.... so yes the almost contradict each other but, if you use a supercharger to spool a BIGGER turbo then it works out. boost is boost... its pressure that is force fed into the intake of your motor. w/ fine tuning you can make this happen. i believe it is a waste. you are better off spraying off the line to spool a turbo faster.

hope this helps you out.

thats not necessarily true. JRSC hits max boost (6psi) at like 2k and holds till red line. and SC's max boost and when it hits it has a lot more to do with pulley size. yes thats only way to really control it. but the size of the SC alone. the type of SC. centrifugal, much like a turbo, will typically increase boost as rpms increase. however the roots type or twin screw, like the JRSC, are positive displacement. they always put out boost. even at idle, they'd put out around 2-3psi. but most, if not all, have a bypass so there isn't any boost at idle.

Re: What is turbo? What is a super charger?

how is that possible.... as the rpms raise so does the rpms of the charger's pulley. so your saying if the rpms increase you stay at the same boost level??? how ...there is nothing to keep you as the same boost level. the pulley will rotate faster causing more pressure. do you have any documented proof from ex: JR on this so i can clear up the confusion.

Re: What is turbo? What is a super charger?

ask and you shall receive.
read under where it says positive displacement.

this is an excellent reference.

Re: What is turbo? What is a super charger?

I can also concur as I have the JRSC on my car. Whatever gear I'm in and whatever RPM I'm at, when I mash the throttle to the floor, my AEM boost gauge shows me that I'm achieving damn near close to max. boost (starts at 6 and works up to 7, 8, or 9 whichever it holds at) immediately. I know everything from what I've read about it being progressive but it seriously is instantaneous for whatever reason.

I'll try to get a video up sometime to show you proof.

supercharger has a compressor side that is spun by a pulley. by changing the size of the pulley you can manipulate the amount of boost. this pulley is driven by the crank pulley. as the pulleys rpm increase so does the boost. so you do not hit max boost until you are at the end of your rpm range. for example 3 thousand rpm on a 6psi pulley would be close to 1.75 psi.. just and example. you can use intercoolers to cool the air from a supercharger but you will lose pressure in doing so.

high horsepower one should go turbo. something that you just want to slap on for 50more hp then go supercharger.

as far as all this talk about supercharger and turbo... yes it has been done and yes i ve seen the car drive. it was on a scion tc at last years hot import nights show here in ny. the points that i read on this post are valid due to the restrictions of the super being in the way of flow of the turbo.... so yes the almost contradict each other but, if you use a supercharger to spool a BIGGER turbo then it works out. boost is boost... its pressure that is force fed into the intake of your motor. w/ fine tuning you can make this happen. i believe it is a waste. you are better off spraying off the line to spool a turbo faster.

hope this helps you out.


Just so your audience knows, there is a difference between the twin turbos they see stock on Nissan Skylines (with the RB26), Mazda RX-7 (13B) and Toyota Supras (with the 2JZ) and twin turbos on something like a V-8 in a Mercedes. That difference is that the turbos are sized differently in the import engines. The first turbocharger is fed off of all the cylinders and is small on purpose, to spool quickly and efficiently. The second turbocharger is also fed off of all the cylinders and is larger, and at the magical RPM (different on all of those before-mentioned engines) the smaller turbo, in effect, "turns off" and lets the bigger one take over. This bigger one is created for the high-RPM and high boost maps of the engine, making it more efficient.

But a single turbo needs to have compromises made (too small, too big, or right in the middle) as to where its most efficient. So in essence, a single turbo is less efficient than a twin turbo.

Re: What is turbo? What is a super charger?

wow... the reason i guess ive been confused about this is due to the comptech charger i had installed on my friends s2k. as rpms went up the boost then gradually grew then around 7400 it hit 6psi. not sure if has to do to the fact that its different in its design or what i guess im just gonna have to do more homework. im so much more familiar w/ turbo and all motor that ive neglected superchargers.

so why do i keep coming across twin turbo car changing over to single. i can mention 3 off the top of my head and at which one of them a 900 +hp skyline.... the owner and tuner had told me that the single is better because of its steady spool rate. from that i just followed his understanding on it. what do i know... im not a tuner.. i just build H and F motors and do custom turbo kits.... never asked enough questions i guess.

to be honest, I've always known what akaprelude said to be true.

A twin turbo set up is for low and high range horsepower. One spools fast, the other is a larger, but slower spooling turbo. I'm not saying your wrong but I've never heard otherwise.

Well that steady spool rate is true kinda... it's steady because you're going to get lag at the bottom and it'll steadily increase until the "sweet spot" in the RPM range where boost is hard-charging. And guys switch to single turbo setups partly because it's more reliable (because factory twin turbo setups have limitations on how much they can flow) and the real reason is because they can ultimatetly make more horsepower. You can't effectively use a twin turbo setup for more than, like 500whp. If you go over that, the smaller turbo becomes obsolete because the regular flow coming out of the engine will overwhelm it. I would venture to say that people switch from double to single because of the cost in upgrading two turbos as opposed to one.

Damn, I wish I had diagrams and articles to explain this ****. I don't have any real world experience, I've just read and saved like every import magazine from 2002 and I can say I have a pretty extensive knowledge I guess, haha.

As for the supercharger, here's the difference in a ProCharger (aka centrifigul) versus a Jackson Racing (aka Eaton-Roots).

The ProCharger is like a little turbo, only instead of exhaust gases pushing the impeller, a belt turns it. But on the inside of the procharger, it's not as simple as a belt turning a turbine impeller to compress gases, instead, the belt is actually turning a series of belts housed inside the charger and that's why at low speeds, it takes a long time for those belts to effectively turn that turbine. So kits like the ProCharger will really only start to see HP and boost increase above 4,000rpm pretty much as a standard across the board no matter what your application has it on.

The Roots-supercharger has a direct correlation to engine speed because it's only got one pulley on the supercharger that affects how fast the rotors on the inside turn. It'll give instant boost too because when the crankshaft pulley starts moving quickly, the rotors on the inside move in correlation, but since the rotors inside the supercharger are larger than the smaller turbine of the ProCharger, they'll flow more instantly. The negative effect to a roots supercharger is that they are very inefficient. The two rotors coming together to trap and push the air down into the manifold is its design flaw. Because when you try to compress air like that, some of it is going to start getting compressed, but won't enter into the manifold at that time, so it stays out into the intake charge until the rotors come back again to try and suck it in again.

And what does compressed air do? It heats up just like anything under high pressure. This is why our superchargers are inefficient. It creates higher intake temperatures and has a limit as to how much air it can move. This will increase detonation if not using the proper fuel.

Re: What is turbo? What is a super charger?

so this info is from things you have "READ" in magazines. im still scratching my head on the whole twin turbo idea... smaller one and larger/ one to spool other??? usually twin was setup on v6 import motors .... which usually had 3 cylinders spooling each turbo. hence the manifolds split to accomodate each turbo. not 6 cylinders spooling 2 turbos. why would they kill off three cylinders running one of those turbos???

Re: What is turbo? What is a super charger?

No, the motors I was talking about were all inline-6 cylinder. The newest one to use this concept of two different sized turbos is the new BMW 335 or 135. An engine that is in the "V" configuration will have two of the same turbos, with each turbo feeding off of a bank of 3 cylinders, so you are right on that one. But there are very very few V-6 motors that are twin turbo out there as opposed to inline 6 twin turbo. Only the Mistubishi 3000GT VR-4 comes to mind for me and we'll see what technology this Ford EcoBoost uses when it comes out, because it will be a V-6 as well.

Re: What is turbo? What is a super charger?

yea im talking about cars such as the 300zx twin and 3000gt vr 4 twin. as far as the inline six you are right. due to the fact that it is one big turbo manifold you would have two turbos ...one to spool fast to help the other one spool for its high end. okay see there was confusion. i thought you were talking about ALL TWIN TURBO CARS. sorry i dont come across supras and skylines everyday to pay attention to something like that. ive only ever seen them hooked up w/ massive single hairdryers LOL. so we are definetly on the same page.
