Ok, so my statement has got a lot of attention. Turbos have been placed in the front mainly to have the turbo spin up to speed as quick as possible. Not to give it the hottest air possible. And another thing, engines are not producing power because of the heat of the gas burning, its because of the EXPLOSION from the gas and oxygen. Its not a coal burning locomotive, its a car. I thought this was common sense?:icon14:

Maybe I read his response wrong. But that is precisely what he said. He just went into detail. Delta-temp and such? Yep. That explosion you're talking about creates heat. That is energy.

You two are on the same page but different languages. :tiphat:

"First off, heat is the only source of power in an engine. That's why we burn gas under pressure--to create heat."

^ that is what he said......so tell me again that we said the same thing, :gtfo2:I don't think so

Combustion produces what? Give me an answer.

I didn't mean that you two were stating the same words but your ideas are similar in theory. You're on the physical side of things and he's at the chemical side of things.

rufio11 12-08-2009 06:15 PM

I'm saying that the physical force of the combustion is what drives the piston down and gives the power to spin the wheels of the car, not the heat.

So how bout that STS turbo? lol Any progress Brazil?

Wrong again and wrong.

Heat spools a turbo faster, that's why it's best placed close to the engine--where the exhaust gas is hottest and thus most energetic. Everyone seems to grasp that flow of air through a turbo makes it work; however, few seem to fully appreciate the interrelatedness and importance of the heat portion of the equation. I doubt you would argue with F=ma, so I baffled why PV=nRT is such an issue.

Further, an "explosion" in the combustion chamber i.e. an uncontrolled burn of the fuel air mixture is a side-effect of detonation, and is VERY dangerous for an engine. What you want is a nice clean burn front that emanates from the spark and burns in a controlled manner towards the periphery. This ramps pressure up on the piston safely as well as extends the period which the burn produces pressure (i.e. torque). This is why slower burning fuels like diesel make so much more torque. And just as discussed earlier, that pressure is a result of the heating of the air through combustion of gas and oxygen.

I know these boards are for fun and collective education, but you should really be careful when pontificating about subjects which you don't seem to fully grasp. 10 people have probably read that and been like -- "OK, so how do I get more explosion in my cylinders?"

rufio11 12-09-2009 02:53 AM

Its called an internal combustion engine for a reason. Spark plug sparks, sets of the fuel air mixture, explosion happens at the top of the piston travel, and then is pushed back down by the explosion. Did I miss something in the obvious?:shakes head:

On the matter about the turbo needing hot air because its more active then cold air, that only matters if the air (exhaust in this cause) is not moving to begin with. The engine is a Air Pump, what comes in must come out and is forced out with the return of the piston traveling back up. That process is what forces the air(exhaust), no matter HOT or COLD, quickly through the exhaust manifold and into the turbo.

So because there was an explosion before the air could be expelled, and explosions cause heat, (that is why the gas/air/exhaust is HOT and not COLD), things get hot. This doesn't mean that Heat is needed to make a turbo run. Trying to make this as easy to understand as possible, don't get why its not.

I'm not an expert and never claimed to be, but come on, this stuff just makes sense right? We all know that HOT air is very active and violent, and will rise, And COLD air is, lets just say sleepy and likes to stay put. This has no affect on the speed at which the Turbo spools when any engine is running. If that were the case then a hair dryer would move a turbo faster then a leaf blower of equal force. They would be the same if you could control the experiment.

There, I tried to make it easy to understand the way I think about this subject

Thanks for reading.:icon23:

So are we needing hot air intakes now for turbo cars? Just kidding, gotta love it. STS is just another option out there for some people.

zfokaiz 12-09-2009 12:06 PM

and they give you a cool a## sound! but im leaving the heat vs. combustion up to rufio and king david.

1slow370 12-09-2009 04:12 PM

actually there was a guy who did a hot air turbo setup that was actually intercooled using the fuel to promote better vaporization. Was done to an ~88 fiero by a man named "smokey" yunick (not sure on the spelling). :stirthepot:
