OT: Difference between a supercharger or turborcharger? In Cars | Forums

[adadaead]

For all who like muscle or japanese muscle cars. Can you explain to me the difference between the two chargers. And is there such thing as a turbosupercharger or superturbocharger or a procharger (whatever the right word is)?

By japanese muscle i'm talking about Supras(Twin turbo ), rx-7/8, Nissan Skyline, Subaru WRX...etc
I guess there is some European muscle cars except for the exotics but i don't know...
This discussion is open for all you car buffs... if there is any

Both super and turbochargers compress air in order to force more of it into the cylinder, providing more oxygen that allows more fuel to be burnt per stroke. The difference between the two is that a supercharger draws power mechanically from the engine in order to compress the air, whereas a Turbocharger uses the exhaust gasses of the engine, run through a turbine, to power the process.

A turbocharger is more efficient, but cannot be engaged as quickly as a supercharger because it suffers from "turbo lag", caused by the fact that takes time for the turbine to spin up.

The turbo got its power from exhaust gases, the supercharger its driven mechanically or hydraulically from the engine.
With the turbo you got all extra power at high rpm, like a kick when the turbo starts to charge.

The supercharger is more linear in its pressure.
The purpose over overpressure in the inlet is to fill the cylinders better, is more power, more oxygen, and to give more power at low rpm.
Many high rpm-engines have to little torque on low rpm.

The Turbochargers on most large American Piston Aircraft are called Turbosuperchargers but are just Turbos as you would have on your car just a bit bigger....wanna see?

You can see the turbo on here behind the engine, before i replaced it with a brand spanking new engine it came with the exhaust and turbo assy but none of the hoses or baffles............ wanna know how much for one, well about â£48,000 a couple of years ago for one................................
you can throw on another â£1500 to â£2000 plus for hoses and baffle parts then there is labour to fit it, total extras i have seen for fitting one of these with add on bits as above ( Not by me BTW ) was well over a cool â£10,000

Oh and yes the oil filter does have that support structure above it so it is a pain in the proverbials to remove it or even undo it as a spanner wont fit on...

Cars bite. Really! You take the best car in the world, and give me the worse airplane in the world, and you'll never catch me.

I know it's a truck and marine engine, but the Detroit Diesel series takes some beating. Anything upwards of a V6 (V8, V12, V16 etc), it was a turbo-supercharged, 4 valves per cylinder two-stroke diesel! An engineering masterpiece, but juicy as hell!

i can guaruntee that the fastest car in the world will smoke the slowest airplane in the world . . . .

yeah, diesels basically have to be turboed or they hardly produce enough power to drag their own weight around, let along a truck.

Fun thing about a diesel is, especially with that cummins turbodeisel you can get in Dodge trucks is this: you can up the mixture and the compression to crazy levels and the thing keeps giving you more and more power. sure, its dumping unburned gas out the tailpipe, but the power it gives is incredible. I've got a vid of an F-350 with a Cummins turbodeisel in it (Dodge engine in a Ford truck, I know . .) . . the thing is lifted, has big knobby offroad tires. Not a car you would expect to be overly fast, right? Well its at a drag strip, facing a Supra. lights go green supra jumps ahead, then the F-350 takes off, leaving a black cloud out of the tailpipe and runs a 10.5 or something. That truck does a faster quarter mile than almost all the hypercars you can buy. I think the Enzo runs the 1/4 is 11.something. Of course, the Enzo is going to have a higher top speed and there will be no handling comparison, but for brutal acceleration the giant american diesel truck wins. The race being over, just set your mixture back to normal and drive home, truck as normal as could be.

if i remember correctly..

a SUPERcharger, takes the same power curve of your engine, and litteraly just bumps that curve higher.. making more power thu the entire rev range (but keeping the same curve more or less)

A TURBOcharger, can be tuned for low, mid or high rpm boost.

(more or less in quikest of laymans terms. im sure ill be correted if wrong :P )

Her is what the Eaton mechanical supercharger on my Cobra looks like



It's the big grey thing on top. The air is brought in through the throttle body, compressed by the belt driven screw inside the compressor, and forced over a water to air intercooler to inject compressed cold air into the cylinders. (It has it's own radiator as well) It produces 9 lbs of boost and adds appx. 25% more horsepower and torque to the engine.

Here is an aftermarket Procharger system on the new 2005 Mustang;



You can increase the horsepower significantly by increasing airflow into the compressor and reducing backpressure on the exhaust. Read that as a new air intake & larger throttle body as well as tuned headers and low restriction exhaust. You can also increase boost pressure by simply putting a slightly smaller pulley on the compressor, but if you go too far, you will blow up the motor!

It produces alot more low end torque as well as giving you a wider power curve as mentioned above. increased torque is what you would want to take off quickly without loosing traction and smoking the tires.

They needed them on high altitude fighters to increase the oxygen level in the fuel/air mixture so it would ignite correctly. On a car, that is usually not a problem.
