This may seem a lil stupid, but can someone explain by diagram how our supercharger sysem works. IE: start at the intake and end at the exhaust... thanks! iam new to boost...

this should help you out a bit

That should help.

 

tagged for later...always good to get a walkthrough

 

Goddamn.

Someone really took their time in a CAD program, that **** is so detailed, it looks real!

 

it's actually pretty simple. you have the throttle body, which is on the top driver side of the supercharger. when you step on the gas, the throttle body opens, and air goes through it. as it goes through the supercharger, the air goes through the supercharger rotors and gets compressed. that compressed air then goes into the inake manifold. the pistons move down, the intake valve opens, and the compressed air is sucked into the piston, and your injector shoots a little big of gas as well. the intake valve closes, the piston moves up, compressing the air even more, and then the compressed air/gas is ignited, which forces the piston back down. as the piston goes back down, the exhaust valve opens, and the burnt air/fuel goes out it. it then goes through the exhaust manifold, through the cat, and out the exhaust pipe.

 

ok well maybe i should of been more detailed for what i was looking for... the biggest concern is where does the intercooler come in? with turbos the air is cooled first right? or am i wrong... uuuuggggg... i just thought the intercooler had something to do with the air but iam all mixed up between turbos and superchargers...

ok so maybe the cooling system now...


and if its not too much how does meth injection work?

 

The aftercooler (on an ss/sc) cools the incoming air. As air is compressed it heats up, hot air = bad in laymans terms, so the aftercooler cools it down so the engine can more efficiently burn it.

Intercoolers are the same concept except they go about it a little bit differently

 

Youa re correct the intercooler does have to do with the air. The SS/SC is intercooled using a water/coolant mix.

In the video you see the air comes in and is blue then turns orange as it gets warmer going through the SC. Then it is orange just after as it travels through the intercooler and turns back to blue on the other side of the intercooler after it has been cooled. On the SS/SC the intercooler is built into the front of the intake manifold.

On turbos they can do either an air to water in the same way as the SS/SC does or air to air which takes the air after the turbo then runs it through an air to air cooler to cool the air. The air is then pushed into the intake manifold.

 

ok so lets get this straight

air gets sucked in through the filter, then it gets compressed in the supercharger, then it travels through the intercooler/aftercooler, from there it goes into the intake maniflod.

is that accurate?

just wish there was a vid like the engine one for the cooler...

 

Typically on a turbo, the air is run directly thru the intercooler for an air-to-air setup. Because of space constraints on the SS/SC, the air is run through the intake manifold which has small tubes with fins similar to a radiator which takes the heat out of the air, transfers it to coolant, then the coolant is run through the aftercooler.

Someone correct me if i'm wrong

 

yeah, the S/C intake manifold has the aftercooler built into it to cool down the charge before going into the intake ports.

 

ok so theres one in the intake manifold that cools down the charged air, transfers the heat into the coolant, than the warm coolant travels through the aftercooler (in front) cools it, then recirculates?

 

Yes

 

yeah if you watch the video again you can see them in the intake mani

 

ok good good, glad ive got this settled, ok now how does meth injection work?

 

The warm coolant from the intercooler (also the aftercooler - it is the same thing) travels into the Heat Exchanger which is the radiator mounted on the front of the vehicle, in front of the engine coolant radiator. The heat exchanger then cools the coolant and it is pushed back through the intercooler to cool more air. The actual intercooler itself is in the engine video posted above - it is the part on front of the intake manifold that is 4 tubes with radiator like fins on them.

I believe most people using meth injection on the Cobalt spray the mixture just before the supercharger.

 

i dont know why but i always thought that a heat exchanger (one in the front) was called an "Intercooler" ? dont know where that started

 

Seems to me that supercharged cars have a aftercooler, and turbos have a intercooler.

 

I believe that to be technical:

Intercooler means that the compressed air is cooled internally during the compression process. Therefore anything which cools the compressed air is intercooled.

Aftercooler means that the compressed air is cooled after the compression device. Hence an intercooler is typically also an aftercooler.

Thanks to Wikipedia I can give a good explaination as to why the two terms:

"The inter prefix in the device name originates from historic compressor designs. In the past, aircraft engines were built with charge air coolers that were installed between multiple stages of supercharging, thus the designation of inter. Modern automobile designs are technically designated aftercoolers because of their placement at the end of supercharging chain. This term [intercooler] is now considered archaic in modern automobile terminology since almost all production vehicles have single-stage superchargers."

right on....although its not really being sucked in its being brought in due to the lower pressure in the chamber...kind of like gravity

j/w...overboost are your calipers painted sb orange?
