2 Heat Exchangers in series
Ok folks, with the texas heat going on in full effect, my IATs are very high to the point where I am loosing timing and hp.
I can get my hands on the oil cooler that goes below the factory heat exchanger at an angle. Since my car is an 03 it doesnot have this oil cooler. I plan on using the stock oil cooler in the same location as a heat exchanger which will run in series with the stock heat exchanger. I already have a cm30 pump.
Will this setup be beneficial in terms of iat or is it just stupid. I want to keep my iat lower than 140 since I heard after 140 F the timing is pulled by 9 degrees.

Absolutely! Renntech has one that is included with their pump... very expensive. I'm putting one on my car as we speak...
The Renntech heat exchanger is 19" x 3" x 1.25" in size (not including end caps) 24" including endcaps and connectors. And it is run in series with the stock heat exchanger...

Well like usal I have some input, So it been bothering me these high IAT, and it seems like no mater what you do there is so little change to them. It got me thinking, The placement of the IAT is where? To me it looks like it is in the Y fitting that comes out of the supercharger going into the intercooler cores. If that is correct than the reading your seeing is pre cooling. Now maybe I'm missing somthing but that seemed to make sense. So now the hard part, fixing the problem? The computer thinks your Iat are one thing but you have changed the cooling system to run cooler. What to do...

so, the sensor is AFTER the I/C

I run a supplemental heat exchanger on my car and it works well. However it depends on the size pulley you are running. More boost more heat. Remember you want your new heat exchanger to have more surface area. So choose oner that is tall and long over one that is just thick.

but so long as u are happy thats fine
same goes with their TB's, they are all mb parts reused. Not that there is anything wrong with that

what's more complicate is that their reasoning is in terms of the whole SYSTEM, not in terrms of single parts ...as it was recently repeated to me
therefore it comes very difficult for us to get a new better and stable equilibrium point after modding a few parts alone

Adding an extra HE to the front will help, but you do need a decent sized reservoir to make a difference, especially if you crank up the flow. EVO Sport uses our power steering units and that is the smallest one I have seen that functions well. I have not seen another kit that does as well with a little one. i am still looking to find something that will fit in the bumper. in front of the radiator but below the actual metal bumper so it won't take up airflow. I'm hoping for at least 2 gallons

Shardul, The diagram you made is good, but I think it can improved upon. I would move the pump that is between the reservoir and intercooler as close to the reservoir as possible. Then, completely reverse the flow pattern you had drawn. This way you are feeding the ic directly from the reservoir, which now will have the coolest fluid. One pump needs to push the fluid forward to negate the g-forces on the fluid in the lines when launching. Doing it this way would also make the best use of ice if you decided to add it to the reservoir.
