Heat exchanger help

[JM PRO]

Hi team,

I've read all the other threads we have on this site and appreciate everyone's input. The current project I am working on is a 383 stroker, with Eaton M112 supercharger at 8 pounds of boost. Car will be running E85.

I've got 2 options I have at this stage of the game.

(Option 1)
Buy the Mishimoto heat exchanger that is 26" long x 7" high and 2.25 thick. Add 3 8" fans to it. It will be located behind the crdboard gas tank and below the mid rail. There will be a panel covering the gas tank and mid rail. This location will get very little air flow so fans have to do most the work.

(Option 2)
I have a new cherokee radiator that I bought for a project and never used. It measures 35 x 11.5 x 2.5. Has 3 10" fans. As you can see in the pics, it will be roughly 50% above mid rail and get much better air flow.

My question boils down to how much do we need to keep that intake charge cool. Will option 1 with the hidden, cleaner packaging work totally fine or option 2 is the must. I can also raise the Mishimoto heat exchanger up above mid rail as well for more air.



I am all ears.

Superchargers Achilles heel is intake temps. So keeping the the charge air cool is how you make power.

Getting the heat exchanger out in clean air as much as possible is ideal.
Also get as big of a heat exchanger as you can fit.
Good pump is key and -12 lines.
I learned the hard way on pump and size.

Here is a link to the Mishimoto heat exchanger I am talking about in option #1

first thing you have going for you is keeping the boost to 8lbs. that right there will see air temps of 150-160. high but not unmanageable.

second is using e85 which has a great natural intercooling effect. although dont expect to be able to see the temp drop if you have port injection and your IAT sensor is in the plenum.

you can't oversize the cooler. put the water cooler. put the biggest thing in you can. I would also put a temp sensor in the cooler flow at the outlet so you can keep an eye on it. fans may be necessary if you have limited airflow, but only necessary to run under boost.
