SuperCharger Vs Turbo

Hey pplz i just bought my self a non turbo skyline for the reson i wanna put a super charger in it , what u guyz rekon would b better for street racing , drags , 1/4 mile etc.. ? SuperCharger or a Turbo ?? So hard to choose the blowoff valve sounds soo goood haha thx guyz

Well from what info ive gotten skylines are awd NO..? then thatll end the whole conversation on either go turbo/charger. In a awd case my opinion is to go with a turbo. To put this quite simple AWD+TURBO seems to be the best set up for 1/4 times at the track. You will launch crazy on anyone fwd and slightly have the upperhand on rwd. Your turbo/turbos should you decide a twin turbo set up, should spool madly straight off the line. You can launch at 8000 rms and have full boost from get go. full boost pushin alot more hp you could get from the super charger. why you ask, simple, with a large single or twin turbos you can cheaply raise the boost to insane levels and double the performance from the turbos SAFELY. Your street racing will follow the same path as long as the roads have little grip. I see little to no use to add a supercharger unless your pockets are hurting after getting that skyline.

The skyline is actualy a rwd , u still say the turbo for rwd??

I want to know about the price difference of a total set up. turbo vx supper charger $$$$ vs $$$$$

Full system including instalation and excess parts neccesarry for it.

How does a turbo charger or Super charger blow your engine. What can you do to make sure you dont blow your engine up.

fdassdf yea what he said

Running forced induction can damage your engine if you are running on stock internals. If you are planning on running more than 7 psi of boost on most cars, you gotta replace piston rings, gaskets, etc. because your engine will be running hotter/harder. You also risk detonation (the air/fuel mixture runs lean and detonates too early) when you are running a turbo/supercharger. This can be prevented by buying bigger fuel injectors and fuel pump (so your air/fuel mixture doesnt run lean), retarding and fine tuning your ignition timing(which you should do anyways) and/or running higher octane fuel.

As for price, a turbo setup starts cheap but can build up quick. In addition to a turbo, you need an assortment of mandrel bent pipes, a custom set of headers, an intercooler (strongly suggested), flanges and gaskets, turbo hoses and clamps, possibly new fuel injectors and fuel pump, oil line (for the turbo), and some sort of heat shielding (recommended).

Not too sure about superchargers, that aint my forte.... :biggrin:

Geez. I WANNA TURBO NOW! :crying:

A supercharger requires four things.

A longer serpentine belt.
A supercharger designed for your manifold/plenum application.
A larger throttle body.
A more powerful fuel pump.

Superchargers do not contend with lag, and can make quite a bit of power, as well as being quite reliable. For good examples of supercharger applications, look no further than the Pontiac Bonneville or Buick Riviera. 3.8L V-6's making 240+ hp and equal torque, if not more.

However, I'm unaware of superchargers being available for RB20DE's. (the NA FR Skyline coupe engine, if I'm not mistaken.)

After about 80 SC's won't be as potent as a turbo will be, granted turbos might have a little lag, but once its engauged hang on. Turbo's tend to trap higher 1/4 mile speeds.

the stock 3800's are making 240/280 tq, I have a modified one in my fiero I know the HP is roughly 300 at the wheels. Not sure on torque, either one you do will take work, but I do believe to adapt an SC will take much more.

either way if you want to turbo/sc you'll need to drop the compression some to run a higher amount of boost and as said before go through the motor so you don't blow the crap out of it. Go either way its going to get expensive.

heres a vid of a fiero with a 3800 SC modified http://www.fierox.com/speed.mov the SC whine is awesome, as I'm sure a turbo is too..

I think by now everyone knows the different between turbo and supercharge. I think this will explain it better.

If you need big power from a smaller(or less powerfull) engine turbo is the way to go, but if a big (more powerfull) engine because of the advantages(instant boost) supercharging is the way to.

I hope this helps

Regarding that short clip....... Wow..... "There's 80!"..... wow... that was pretty damn quick.

Yep i still say turbo for rwd. dont you?

A very small turbo, yes. That would work fine. But only a small, easily spooling one.

RWD layout cars, turbochargers, and cornering have a very funny history together. It generally is one of NOT WORKING.

As an example, on which Cbass can back me up on, I cite the infamous Porsche 930 Turbo of the late 70's. One, single, large turbocharger (A KKK unit, if I'm not mistaken) made for a drastic change in the handling of the well-balanced 911. The turbocharger's characteristic was best described as a "light switch". Without careful shifting and braking techniques, you'd deal with a car that skipped from 160hp to 330hp once spooling occurred.

While in a Skyline, this characteristic may be less prevalent, and factory turbo setups are available, it still must be mentioned that RWD turbo cars have had, for about as long as they've been in existence, suspect and tricky handling.

Superchargers have more linear power and torque curves. While they may not produce the sheer power of a turbocharger, I'd still put in a call to Shorrock or Paxton for my Layla before I put in a call to Garret or IHI.

I have a 1ZZ-FE engine it is a 4 banger. it is in a 2002 mr2 spyder. I was wondering what you think I should do to the engine. should I turbo or super charge it. I am leaning toward turbo charging but am woried about the cost and all the other stuff that comes with a turbo.

My Mr2 has sequential transmition. Dont know how that will work with a turbo on it.

Give me your expertice and help me out on what to do to my car.

Something to note: While turbochargers recycle you hot exhaust fumes from your motor one of the advantages of superchargers is that they bring in the cool air from the outside of the car which is much easyier on your motor. You will also need to probably lower the compression on your motor if you turbocharge it (i think for the same reason.)

My buddy just bought a Procharger for his 98 Cobra and it sounds absolutely awesome.(Albeit my ears are still ringing from it 4 hours later)

Turbo gives out more power but less reliable
Supercharger is more reliable, but less power.
i think it will depend on wich one u buy. im 75% wrong on this tho too

Dude, turbos use exhaust gas to spin the turbine, which is connected via shaft to the compressor, which sucks air in through the air filter and into your engine. It doesn't spit your exhaust gas back into the car. And you have to lower the compression if you supercharge at the same point as you do when you turbo.

Supercharger doesn't bring in cold air... nor does a turbocharger.

When you compress air, it generates heat. Which is why you have to lower compression to fight off detonation. And that's why you intercool your system to help cool the air so you can run more boost/higher compression or both.

Both are equally reliable as well, just depends on if you're motor has been properly built for the application. And if you maintain your setup properly as well.

i got a contour with a supercharger on it. Id rather have a turbo personally, they sound cooler, get more eventual power, and are funner to drive

Yeah I just figured that out.....

Not necessarily, the centrifugal superchargers tend to do better up top than the roots superchargers. I see plenty of Centri GTs trapping over 110 with just sc and 117 with some exhaust work and pulley. :dunno:

The difference between the Roots and Centrifugal type blowers is the way the work.

The Roots blower doesn't the compress air. It works like an air pump, it just brings in gobs of atmosphere into the cylinders.

A Centrifugal type, works just like a Turbo. It compresses the air and forces it more or less into the motor. It also generates less heat than a Roots type cause of this, seeing as the actual unit is not attached directly to the motor.


Basically, the Centrifugal supercharger is a motor driven turbo...

Now watch out for the Twin Screws :naughty: :p


I should be getting one by summer of next year :bananasmi :bananasmi :bananasmi

You can launch at 8000 rms and have full boost from get go.


i would love to hear what stock tranny is gonna take an 8k launch

I could easily use an of the 3 and be happy with all of them.

Roots for torque
Centi because they are easy to install, and put out good numbers
Turbo, because I have 3 GTRs :)

i would love to hear what stock tranny is gonna take an 8k launch


Im pretty sure the skyline awd twin turbo tranny is vertually bulletproof. If not an 8k launch take a 6k launch is still the same outcome..off the line OWNAGE..agree?

GTR trannys are the weakest link in the whole drive train. They cannot take that abuse a lot. 3rd will let go.

I forgot to mention, the stock clutch will not handle that many either.

thats what i thought. i havent heard of any stock cars taking those kind of launches (maybe some supercars?)
i figure ya gotta get an upgraded stall convertor or clutch
