New types of turbo's in the works., Interesting....READ!! Options

[d3monc3lica]

I was looking thru the new HCI magazine and i came across 2 new forms of turbo induction.


----------------------------------------------------------------------------------
Squires Turbo Systems (STS)
The first being a new idea first tested on an Acura Integra (go figure) , but it had outstanding results. The turbo setup was situated in the back of the vehicle, under the wheel well!! Where the muffler was supposed to be, the turbo, filter and wastegate were located.........

Turbo Assembly

The second interesting new induction method was created by Cry02, it basically utilzes compressed carbon dioxide gas to power a compressor similar to the compressors that are found on turbo setups. Looks like it could have potential, however finding information on it is becomming a loss for now, ill update when i find more on it.

it's a freaking type R, i was wondering why the no. were so low in the 1/8 and 1/4

That's rediculous. This has got to be a play by a shop that doesn't have what it takes to properly fit a turbo.

1. Turbines are spun be HEAT. That's why turbos are mated right up to manifolds. Putting the turbo way back there looks like a good way to shed alot of heat....

2. I see cold water slpashing all over an orange-hot turbine housing.... I see... small cracks appearing over time.... I see.... small cracks turning into big cracks....

I'm all for trying new things, but this really looks like a hack job to me. I've seen a write up on it in a magazine once, and I was suprised they took it seriously.

You sure about that?

Altho a turbine wheel looks like a "pinwheel" or a "fan", it is a common miconception that its actually designed to work with exhaust pulses hitting the vanes. While exhaust pulses pushing the vanes soes come into play as a sort of secondary order force, turbines really are powered by heat.

Thats why if you look at the exit of a turbo manifold, the ports are pretty small. This would seem to go against the "less backpressure is better" rull for turbo cars, but that adviceonly applies to exhaust after the turbine. Forcing the fresh exhaust gasses thru a small space makes them hotter, which means they have more energy. Once the gasses enter the turbine housing, they expand into the larger spce, and dissapate heat. Again, the turbine wheel is not a "waterwheel" design. That is to say, it's not desigened to catch pulses around it's circumfrence. It's designed to harness the expansion of gasses and therefore the dissapation of heat.

Ok So if I stick my turbo in an oven I'm going to be making boost? Heat being the main factor in making the turbo spin doesn't make any sense.

Haha, not quite! But if you where to dissapate heat from your pressurized exaust gasses by say... running them down the length of your car's underbody where cold air rushes by... they would remain pressurized, but not have as much of the energy to expand, dissapate, and spin the turbine as would hot gasses.

Of course, according to the Ideal Gas Law, we could be arguing semantics here, as there is a direct relation between pressure and heat. However that does not make my initial statement that turbines are driven by heat any less true. Nor does it change the fact that turbine performance would suffer if the exhausts gasses where cooled before reaching the turbine.

Your arguments are true, but how you arrived there is false.

If you are reffering to the part about the outlets of the turbo manifold, then it's down to heat and pressure not being completly interchangable in that part of the turbo system. However, different manifold/turbine housings have been designed to emphasize either pressure, heat, or both. Is that the part that could be considered false or am I lost here?
