Anyone that knows about Turbos?

Question

Hi. I would like to know what will happen if on a small 4 piston 1100cc carburetor engine which from the factory is naturally aspirated and produces 55 Horse powers @ 5.000 RPM I put a huge Turbo from a truck or so...Will the engine handle that much pressure? Do i need a boost controller? will the block snap?

P.S. when I say huge Turbo I mean something like this: http://www.youtube.com/watch?v=GzYl3cF-xMU

Any answers are welcome. I don't even have a car but I just want to know.

Answer 1

nope, sorry..

Answer 2

In order to take advantage of forced induction, you would have to change the compression ratio.  Trying to add a lot of air to an engine that was designed for normal aspiration will result in detonation with will lead quickly to engine failure.  By running low boost levels, you can get a small increase in performance by simply bolting on a turbo.

However to really increase the power output and take advantage of the flow of a large turbo, you would need to modify the compression ration and valve timing.

And yes no matter what other options you choose you will need some form of boost control to avoid detonation.

Answer 3

you need boost controller..

Answer 4

Any weak link in the combustion chamber will give way (head gasket,head bolts,piston crown,cylinder wall....)when the first turbo boost occurs.Don't even try to see the detonation.

Answer 5

I don't think the exhaust from such an engine as you describe can drive the turbine in the link.

The second problem is that of using a carburetor. You will need way to make it air tight to keep the gas charged fumes from leaking out and exploding (or burning) inside the engine bay.

If you work all that out, the engine will self destruct due to detonation unless you work out a new timing curve.

If you could work out the problem, you could start on gas, then switch to diesel when the boost hits about 20 PSI.

To work this all out will take time, money and a lot of replacement engines.

Answer 6

no, sorry
