Hydraulic turbo
 
I was behind some sort of tanker truck today and it had a funky looking turbo-like device on the back that was made to shoot out some sort of liquid.
The concept behind it looked as though it had the normal hydraulic fittings (one in and one out) connected to the center compressor wheel area.
:confused::confused::confused:
When the oil was pumped through it it looked as though it turned the wheel and shot the junk out. Is this even an idea worth thinking about? It just seemed as though you could have instant boost if it was connected to our cars.

Why, hydraulic fluid is inefficient.

All it is a turbo with the intake and the exhaust side separated and in different areas with hydraulic fluid flowing between the two. The only advantage is to keep the compressor wheel of he turbo closer to the intake track. I have only scene it in diesel applications where space next to the exhaust is limited.

This may be an option for an ambition RX-8 owner in the future where exhaust space is an issue, but stick to the old snail type for the FD.

oh yeah, i was thinking about replacing mine, I would only look to get some pre-boost. :D

edit: I wasn't thinking about replacing mine

it's called a centrifugal pump....which was probably conceptually invented/implicated long before the turbo or internal combustion motor was used

even before the wheel itself was invented??? kidding

Well thinking critically,

A turbocharger's main advantage is that it uses exhaust gas to drive the turbo. Call it 100% efficiency since it doesn't sap energy from the driveshaft.

A supercharger uses a motor to drive the turbo. Nearly instant response. I don't know any auto-specific numbers, but motors/alternators generally work to 90%+ efficiency. That means you'll put 81% of the energy back into driving the turbo that you've sapped off the driveshaft.

You're talking about using fluid to drive the turbo. The Tookwikcharger, haha. It would be nearly instant response, but wherever you get it from you'd need to beat 81% efficiency. Considering friction will be a major factor, plus the fact that efficiency varies across the range of turbo rpm, you probably won't beat the supercharger. And the mechanicals would be messy.

PS: I know that isn't your sweet a$$ in the avatar, so whose is it?

yeah, that is my ass in my avitar. but anyways...

Talking about the turbo, what i mean is... would it be possible to supplement the existing turbo with a hydraulic system that could be creating 'boost at idle' if you will?
It seems like this would require modifying the turbo to much though.

Oh and back to the ass, its really not mine, its my girlfriends...:crazy:
Not really, its Vida Guerra.
