"with almost no tradeoffs."

I win. I never said how much power it took away I just said there is some. it might even be 1 hp for every 50 but its something.

or this.

well you are a little bit right but mostly wrong ..... heh

Nothing is free but the comparisons to supercharging are an eye opener...
I didn't realize how much turbochargers were using the heat energy.

/\ yeah - good reason to keep the turbo close to the exhaust ports ........

Superchargers are more unique!

Yep that's how i am with everything.

Dangit! let me have a win somewhere.

BTW they can't be "more unique" they are either unique or not . Am I starting to piss you off yet ? LOL

You would never piss me off every time you post I see boobies.

:yelrotflm

Boobies - the answer to all our problems ....

Except for your avatar... That is all wrong!

But Brettus' on the other hand....:worship:

I was under the impression that if you were to take energy from something and use it that you could not replace it with the same amount of energy.

For example a turbine spinning from exhaust gases, yes it will blow by but you are restricting flow which will impede power.

Hmmm maybe I'm wrong.

You are exactly right, there is not a free lunch; energy is not created from nothing.

I would like to see the following on a normally aspirated car:

Dyno test #1 run a normally aspirated car with a turbo on the exhaust and the boost going into a closed chamber; then you would see the amount of power lost to the exhaust restriction under boost.

Dyno test #2 would be the same car (turbo now removed) with a blower mounted and the boost going into a closed chamber for a comparison.
I think the turbo would loose less power in this test than a blower, but there would have to be a measurable amount of power loss for each.

Updated:
Only nitrous is a "free lunch", but only because the gas was already compressed when added to the car.
And you pay for that lunch when filling the bottle!

how are you gonna discharge the compressors into a closed container? i seriously doubt a turbo would live long enough to finish the test. and a positive displacement compressor like the SCs is no better... closed chambers fill up. that changes pressure delta's which they need to function properly
