Tubos and Superchargers

Does anyone know if any vehicle was produced with both a turbo and supercharger?

I had a conversation with someone and he says that there are such cars that came as a standard. But I do not believe him, because he could not name one.

Hope I can get an answer from this board to end the despute.

Thanks,:confused:

I think it's called twincharging, and though I don't know any cars that came equipped like that, it has been done.

twincharging- thats messed up. it would probably be unreliable.

The Nissan March, and the Lancia rally cars had both a turbo and a supercharger. There was also a fairly popular kit to add a turbo to the Toyota MR2 that already had a factory supercharger.

It is a very good system indeed, but cost and complexity are the only reasons there are not more twincharged production cars.

In fact a twincharged engine would produce more tourqe than a twin turbo, and almost as much hp.

Have to agree totally with that Darkaccord.

Once you have the supercharger and turbo bolted onto the engine, you can vary the blower drive ratio, and turbine a/r to get any boost characteristics you want.

It can be more supercharger like, or turbocharger like, or something in-between. I have done this myself, its great fun and very educational.

As for reliability, if its properly engineered, and properly maintained it will be completely reliable, in the sense that it will not leave you stuck on the side of the road somewhere.

But like all things automotive you need to look after it as well.

how complex would twincharging really be?

Not very.

space and weight are probably why no one uses both.

I think people don't think they need tourqe. Thats somewhat true but only in a really light car.

Yeah, thats why a 200BHP car without a turbo can always beat a 500BHP car with a turbo. All that space and weight is a killer.

Now all you need is a complete comedy routine so you can go make money like Seinfeld. :rolleyes:

he was refering to using both a supercharger and a turbo. now a 600hp turbo car could probably beat a 700hp twin charged car that weighed in at 200 lbs more with all the weight up front weighing down the wrong two wheels. :thefinger :icon16:

i'd like to do that toa car sometime.

Who 'da thunk a 200lb supercharger! Wooo-eee Cleetus!

yur asking a lot of yur engine by having both a turbo and supercharger.

O/k, which is going to stress out the engine most ?

Turbocharger at 15psi boost
Supercharger at 15psi boost
Twincharge at 15psi boost

If all are properly intercooled and tuned, and produce similar maximum torque and power, why is one going to blow up your engine and another not ?

Stop yelling yur ruining my birthday:mad:

Why would one blow up my engine?

It can be done reliably and not much more than just Turbo - I've done it.

would someone please tell how on earth turbos and superchargers work in laymens terms.please be as informative as possible:dogpile:

LOL...I'm a super noobie but I guess that it'd be easier for me to explain it to your because I won't even use car terms to explain it. LOL. Correct me if i'm wrong but do it in a nice way, because when it comes down to real life, i'm a nice guy but I can eat anyone's head off with my fist :P.

Anyways, turbochargers and superchargers work based on the same principal to give you car more horsepower and torque. They compress the air going into the cylinders (using a compressor, LOL), which contains the oxigen needed to create the powerful explosions. Now it's not because the air is compressed that the explosions are more powerful, but it's because there is more room for fuel to enter the cylinder. It's a more compact way to add power rather than putting in an engine with a higher volume in the cylinders. Thus, we get the idea that a 5.0 L engine is more powerful than a 2.0 L engine because more fuel and oxygen can fit in each cylinder in order to create more powerful explosions. Turbochargers work on the exhaust of the engine in order to spin a turbine inside the Turbocharger and allowing it to function. A Supercharger uses the power of the engine's rotations in order to provide more power because blocking the exhaust of the engine is not a good idea in my opinion.

Well, that's the basics of it and probably all you need to know!

By compressing the air, you have more oxygen molecules to combust with gasoline (assuming you can keep the air/fuel ratio steady). This means that there's more pressure from the explosion, which means more torque, which means more HP.

I won't get into the rest.

A turbo is not "blocking the Exhaust" as bad as you think.
Lets say you have 2 identical cars both running 5psi, one form a turbo and one from a supercharger. And you run the 1/4 mile.
The one with the turbo is gonna be faster, because the supercharger takes more power to make 5psi than a SC.
I dont know exsact %'s but a SC takes like 15-20% of power away and a Turbo takes like 5-10%.
Now I know some one is gonna say "but the SC does'nt have lag and the turbo does" welll yes that true, but as long as the size of the turbo is matched with the power you plan on making it will not be a problem, the lag time will be made up in efficancy.
That and on roots style SC its diffecult to run a intercooler.

Remember that a turbocharger uses the thermal energy in the exhausts to power the compressor, most people tend to think that they use the velocity of the gases an the flow. The downside of this are that there will be a pressure increase in the exhaust manifold, however with a efficient turbocharger the pressure in the exhaust manifold can be held at the same pressure as in the intake of even lower.

You car correct sir! You must of read "Maximum Boost by Corky Bell" to?
So in a way is free enery that usally wasted.
