Larger Maggie intercooler

I want to change(supplement) the intercooler on my Magnuson supercharger. If you are familiar with the setup, the intercooler is at the bottom of the supercharger, with a holding tank of radiator fluid that sits on top of the battery(at least in the Corvette).

What I want to do is set up a small(?) intercooler that would be mounted near the radiator. I want to do this to lower my IAT's, the built in intercooler just doesn't lower the temps low enough. How much would something like this cost, and where could I get this done?

:popcorn:
 
Don't get rid of the intercooler under the blower just add a heat exchanger to pull the heat out of the IC fluid......that is probably why your IAT's are so hot. The fluid heats up then is just recirculating in the system and being stored under the hood where temps are already hot.

It would be very cheap to fab up especially considering all you are doing is adding it into the system already installed on the car. Fab the brackets yourself, and use a front mount water to air heat exchanger from a Lightning/Cobra/GT500. Reroute some hoses and you are good to go.

That is exactly what I am talking about. I was thinking of adding a radiator(heat exchanger) down near my radiator and then add more coolant to the holding tank or just getting rid of the holding tank.

I need more cooling of the fluid that is run through the supercharger, and the tank just isn't doing it.
 
You could remount the tank in the trunk (to get it away from engine heat) and/or get a bigger one. Like I said, go buy a heat exchanger (aftermarket or OEM) from a Lightning/Cobra/GT500 and fab up some mounting brackets to hang it in front of your radiator, then run the appropriate hoses. If you get an OEM heat exchanger (still very effective) this project wouldn't cost you more than $75 in parts.

Side note......what kind of IAT'2 are you seeing anyway??

FWIW, dont use coolant... use straight water and if desired a bottle of water wetter. It will cool much better than any coolant will.

also as stated, just get a good quality heat exchanger and mount it up front. dont get one of those cheap autozone/ murrays ones with the tube and fin design (they dont work well).
 
The Maggie intercooler uses Dexcool to cool the supercharger, so I will use that. However, would a small air-to-water intercooler work to cool down the fluid? I m thinking it would. On really hot days, the temps can hit 240 degrees. This is with a 170 degree thermostat and my fans coming on at the lowest setting in the ECU. I figure I need more coolant and a more efficient way of lowering the temps in the coolant.

OK now I am confused.

So the aftermarket IC system pulls fluid from the OEM cooling system?? Or do you have a dedicated intercooler system (with its own fluid)??

Because if the system is dedicated your thermostat and fan setting have little to do with the IC temperature (it will help to run them cooler but not significant advantage).

And if the system does pull from the coolant system than you are SOL. Adding a small heat exchanger in front of the stock radiator isn't going to help at all. Your engine will heat up that fluid far faster than you can cool it down. About all you can do is get a huge aftermarket radiator, good set of fans then run your lower thermostat and use water/Water Wetter mix.

With the Corvette, you have a stand alone tank that is connected to your Magnuson supercharger. This supercharger is a closed loop system that runs from the tank to the supercharger, then back to the holding tank. What I want to do is put an intercooler(heat exchanger) between the holding tank and the supercharger and put this down near my radiator where I can get some airflow to reduce the temp of the coolant that flows through the supercharger. The Magnuson are famous for heat-soaking, so I figured that if I put a radiator type intercooler(heat exchanger), I could lower the IAT's.

OK then follow what I said previously. I was just confused when you said......

While it is good to keep the engine cool, it is doing very little to lower IAT's.

run water/ water wetter and no coolant, youre leaving a lot on the table running coolant. trust me. the only downside is if you drive in the winter, youll have to add coolant. but in the summer, dont use it.

and as already stated 5x, just put a heat exchanger in front. ive found that the Setrab stack styles work excellent!
 
there is the CTS-V heat exchanger, it is huge!

there is also some talk of slowing the pump to get the most cooling from the heat exchanger.

You could get another vette one and double them up, might make it easier to mount.

Meth!
 
im on board with water/water wetter in both your intercooler system and in your radiator just make sure to change that before winter time. add a front mount heat exchanger too. i dont know what kind of turner you use, but with hptuners, i have both of my fans come on at 195 and off at 190 i've never seen my car above 200 even with the ac on, i've never really been a fan of low temp thermostats.
 
I have a very similar setup on my cavalier. Intercooler cores are inside the intake manifold.

I used a intercooler pump from a ford lightning and an aftermarket heat exchanger made for a 03 cobra that I found on ebay. The system calls for dexcool but I found better results with distilled water and water wetter.

If you can get rid of that heat it will make a big difference, I also run a water/meth injection setup that goes through the s/c. Keeps the supercharger cooler and the charge air.
