Another Mopar Off My Bucket List - Barracuda Fastback

I believe the only option you have that is anywhere near efficient is to add the 4" inter cooler to the top of the manifold. You can try to get something into the manifold but it won't be big enough not to heat sink and be useless.

I have had this conversation more than once with a very good FI builder. He builds high buck TT setups on very spendy cars for a living. The heat soak is worse on a blower car because it is working ALL the time.
One thing to check though, is that if whatever core you use, be sure it can take the pressures of an A/C system. Most of them aren't made for higher pressure systems.

The exchangers my son ordered were rated at 250 psi. We had avoided the top mounted intercoolers because of height (and expense). The thought of using one of those center mounted heat exchangers from them did occur to us but we were afraid to lose the manifold's center supports thinking that we might ruin the ability to have a good seal between the manifold and blower.

I had suggested to my son that we try to consult with 'bigger brains' before making a decision on direction. He believes that the coolant flow will be fast enough to stay cold inside the intake. I was intrigued about the prospect of making our own system but didn't want to expend the effort on a setup that wouldn't produce a gain.

One of my concerns was that this particular manifold does not have the typical air gap beneath it that you see on Chrysler big blocks. The hot oil splashing against the bottom would further heat our intake charge. I suggested that we add an aluminum shield beneath the manifold to prevent oil from being flung directly on the bottom.

If you're correct and this design will be too inefficient to provide a cooling effect, I'm not sure we could tell without putting a temperature sensor inside the manifold. We could test with the compressor on and again with it off. My son is pretty adamant about staying the course. I think he gets upset with me when I suggest drop kicking this idea to the curb. He's controlling the purse strings on the project so the final decisions are his. I commend him for trying to be innovative whether or not he succeeds. I wish that I had more experience with these things so I could give him more intelligent advice. - That's why I am very interested in your input. Maybe some of your advice will sway him or lead to further modifications that will get us to a system that will work. Thanks.
