Intercooled??

[Special Ross]

Is the Eaton/Magnuson S/C intercooled? Does anyone know if the S/c from RSM is intercooled too?

No they are not.

[Special Ross]

I assume intercooling is good. I don't know that much about it. How come there isn't an intercooling setup?

Thanks

no room...

i believe that superchargers also produce less heat than turbos that's why you don't see many setups supercharged wise w/ intercoolers... also in the 3.4 there's less space to work w/....

i duno really just assuming and making stuff up since it kinda makes sense.. ;)

hopefully someone w/ the hardcore knowledge will chime in.

With our cars, room is definitely a problem. The cooler the air, the more dense it is and more oxygen per square inch at the same RPM's. Engines LOVE cool air. You'll likely see a LOT more AFTERCOOLED superchargers than intercooled. It cools the air AFTER it comes out of the blower. If I remember right the air is cooled BEFORE it gets to the blower when it comes to an intercooler. Overall if you can find room for an intercooler, definitely go for it. It'll make the set up a ton more reliable :)

A starion intercooler fits. You would have to make your own piping though.

All intercoolers go after the power adder. Thats the point of them. TO cool the charge that comes out of the SC/Turbo. Aftercoolers are watercooled. Intercoolers are Air-Air

[Doug]

Oh yeah a superchargers generally don't heat up the air as much as a turbo. Unless you have a big SC or its out of it efficiency range.

[jaketuff]

You could always use the world's best known "intercooler,"

N20!!!!:D

That too... if I remember right a spray of NOS will charge air to like -127 degrees farenheit almost instantly. Even with a small 50 shot. It's cool :D

Not sure how you would hook it up but hey.
it's designed to go in fornt of a front mount intercooler and gets air temp way down.

Even a 35 shot nitrous kit would seriously boost the SC's power because it gets the air charge so cold.

[Doug]

The problem with those kits is when you spray your intercooler the intake charge temp goes way down very fast. Most cars can't handle the extreme change in temperature that quickly and lean out big time. My friend was doing this to his FD and almost blew it up.

well seems like some tuning troubles there. people due this all the time with CO2 fire extinguishers. Gives the same effect.

If what you were saying was true the same thing would happen with nitrous in a N/A car. It drops the intake air temp way down, lower than spraying an intercooler.
So nitrous cars would blow up as soon as they sprayed.

Sounds like your frined isn't getting enough fuel. Most people with turbos stay way rich to avoid any type of problems like this.

[Doug]

No, This kit is spraying N20 on the outside of your intercooler. When your spraying N20 into the engine you also spray extra fuel. Hence you have both a nitrious and fuel solinoids. When you spray on the IC you are not giving your engine any extra fuel and the computer can't compensate quick enough.

Not always true
There are people running dry kits.
The reason you add more fuel with nitrous is the same reason You get larger injectors and such with a turbo.
This falls about under the same thing as with nitrous kits that look at O2 readings to add more fuel. it's too late for that the nitrous has allready been burned. This is why dry kits arent that safe even if computerized. But with the turbo and more air or colder denser air. it will raise boost pressure and the map or maf sensor will pick it up and adjust fuel curves since it's moving more air. nitrous is added after the maf so it wont pick it up and for the amount of power being added the map isn't reading much. this is why you have to add nitrous with the fuel. the motor doesn't really know how to read it or most of the time can't even see it.

If the engine is still haivng troubles then it's pushed too far out of stock parameters and needs fuel mods to work properly with the n-ter cooler. he would get the same problems by upping his boost. it's not really the fault of the n-ter cooler. Just sounds like the stock fuel system is being pushed almost to it's max.
kinda like the straw that broke the camels back thing.

[Doug]

The cars fuel system is no where near stock. He has a big single turbo and is pushing about 18 psi. He has about 20 grand (3mm race seals, Race Port) in the motor and everything supporting it. His Power FC controls fuel and adjusts it accordingly. The problem is it can't read the change in temperature quick enough. His RX-7 made over 500 whp last time he dynoed. And thats with out the IC spray.

anyway

Our cars (2.4L) only have a 1 bar MAP sensor so it can't see any boost. Thats why I have to use a check valve. So it can't adjust. And it wouldn't matter because my car is Speed Density and at WOT uses set parameters for how much fuel the car gets. Thats why I have to use a S-AFC to control my fuel at WOT.

So I guess the IC sprayer would work on the 3.4L better :)

[aleroboy]

I wonder if the 3 bar map used in the 2.4L sc kit would help you at all. As well as the factory reprogram they do to make the car read boost. Just a thought.

[Doug]

I believe they use a 2 BAR on the GM SC kit. The problem is that the sensor itself is 212bucks without the program. Then you have to convince the dealership to reprogram your computer. If they are allowed too.

Well it's cheaper than a stand alone. :p
everything has to cost a fortune now days:(

[SpyhunteR]

it's expensive but the 2bar sensor and a lil reprogramming of the stock ecu would go a long ways..


problem.. finding someone who'd be willing to do it...

[Doug]

Yeah but you get a lot more with a standalone like the Haltech.

[SpyhunteR]

well obviously.. and you would hope so.. since you can pretty much change and screw w/ whatever you want on the haltec...


jeeze.. thank you mr. obvious
