Is my S/C Intercooled? Pics attached.

[after_shock]

I dont think it is but just after some confirmation as to whether my S/C is intercooled or not?

Apologies about the bad light in the pics had to take them last night and it was the only chance got to do them!

First 3 are of the back parts of the engine and the last is a side shot of the front incase any of the pipework runs that way for it.







Thanks

Before the air enters your S/C it should pass through a raditor (Intercooler). Should be a good a place to start.

The intercooler is mounted beneath the charger. If you have one there should be water hoses leading to a small radiator strapped to the front of the main rad. You would have a water reservior and mini pump also. From the pics is doesn't look like it is intercooled.

Check for the hoses, reservior or second rad.

Incorrect. You cool the air leaving the S/C.

Didn't realise that the pulley was at the back of the engine I thought they were always at the front ? Cleary not though - is this just on one type or sort of charger ?

As has been said if it is intercooled you need to look for another rad at the front of the car.

That is not intercooled..............

Thanks for the replies!

Just trying to work out the next path to go, really dont want to start taking the engine to bits, pistons/heads etc just work with whats on the outside, air filter, manifolds, s/c and go from their.

HHmmmmm... me thinks the first thing you should do is enrol in a basic mechanics course! S/C have a radiator in front of the main rad for cooling the matrix inside the SC itself.

i doubt wheather a basic mechanics course would cover a supercharger i learnt somethin out of the this though not all chargers have the belts at the front of the engine

[MadMaxHSV]

All chargers will have the belts at the front of the engine to drive off the crank pulley, but some have them at the back as well with a transfer shaft to the front (Harrop and Maggie's) so the orientation of the charger housing allows for a shorter path to the air intake (ie. the inlet is at the front).
The Harrop run the transfer shaft underneath the charger through the valley so its hidden.

I was only looking where I was told to look!

erm thats some scorching on the exhaust manifold heatsheild

Please tell me how you cool the air once its left the S/C as the S/C itself ports the condensed air mass straight into the head... Please tell me! You seem so confident about your knowledge... Saturate me with information!

All turbo cars induct air through a filter, then via an intercooler and then forced into the engine..... I know its the same with a S/C engine..... Please prove me wrong.

There is a 'radiator' or two under the SC that cools the air leaving the SC before it enters the heads. These radiator(s) have a selfcontained coolant circulating system with the coolant passing thru another radiator in front of the car.

and so confident too!!!

Firstly, turbo cars don't draw air in via the intake then cool it. You don't seem to understand how the process works.

Why would you cool air at atmospheric pressure and ambient temperature, then compress it and get it hot?
It gets compressed first. Compressing air generates lots of heat, hence intercoolers being used to cool it. Engines like cold, dense air.

Induction > Compression > Cooling > Combustion. Just incase you still don't get it, here's a picture. Tip: start with 'ambient air inlet' and work your way around the system.



and here's an illustration of how a turbo works...



So as you can hopefully see, air gets compressed, then cooled, then fed into the engine.

Superchargers are the same in principle, just executed differently. The air is still compressed, but it's done mechanically as opposed to using the exhaust gas turbine. The process however, is exactly the same. Induction > compression > cooling > combustion.

So if you'd like to explain the logic behind cooling before the air is compressed, I'd love to hear your theory as to the thermodynamic advantages! It'd certainly have me re-evaluating what I do for a living if you're right.

As I'm sure we both know, not all superchargers require intercooling, nor do all turbos to a lesser extent. Low boost pressure = less compression of air required = less heat generated, you can get away with it.
Where higher boost pressures are used, there'll be more heat. Thus somewhere between compressing the air, and the engine using it for combustion, it makes sense to cool it, agreed?

Where superchargers are used, you'll find the coolers are still placed between the blower and the engine regardless of setup, if intercoolers are used that is. Of course, this means in some cases, like the ones you refer to, they're not visible.
Often these are 'charge coolers', where water is circulated to take the heat out, passed through a small radiator to remove this heat, and so on. As it gets a bit hot in there. They sit between the intercooler and engine.

As for examples, well below there's one of millions randomly plucked from google...I'm sure eaton and the like have plenty of pictures for you to look at. I believe the LS9 has the setup you don't believe exists, standard fit.

So there we have it, you can now consider yourself saturated with knowledge, and proven wrong, as requested.

Epic fail!

[V2RAC]

Serious question, in a two belt sc set up (front and rear) What is the rear belt for and what does it connect with? I'm assuming the front one drives the sc internals. I await "saturation"

[MadMaxHSV]

The front belt connected to the crank pulley spins a pulley on the front end of the transfer shaft.
This shaft runs to the back of the engine bay where another pulley connects via the second belt to the actual SC pulley spinning the rotors.
This just allows the SC pulley to be at the back so the intake can be at the front.

I do apoligize, STU R you have proved me wrong. I was unaware of any cooling radiators before the supercharged air enters the block. And yes it does make sense, I take my hat off to you. However I did not fail epicly. All Turbo cars do induct through a filter, then through the turbo, Via an intercooler then into the engine.
