Man, I never saw IATs higher than 135F. But 180-190F, holy cow!:fearscream:
Have you ever thought about a small tank of compressed air to blow cold air into the intake... you know, "only when necessary"? ;)

Would need a big ass compressor :tearsofjoy:

Yea, 180-190F was just cruising on the interstate. Imagine what it would be like if you tried to do a pull.

That is actually quite a bit worse than my cruising IATs, even after the car has been heat soaked on the freeway for 20+ mins. Then again, I have the ADE 1K fmic.

Ha Ha! And I remember asking Dzenno what he thought about spraying water on the FMIC 5+ years ago on one of the other forums.
@R.G. how did it work for you? Did you see IATs drop any?


It works Jeff. Also a complete waste of time. Methanol or just a decent IC and no puddles will need to be left in staging lanes.

You could always build a new manifold with the A2W exchanger built in
This is what needs to happen. High HP SVT Cobras and AMG 55K cars still run the Water to Air cooler under the intake manifold. Once that's complete, utilize an AC cooling kit like Killer Chiller

Regardless, I still want to try an A2W barrel style core, inline with the A2A FMIC. Its just a matter of finding one that will fit.

I think you mentioned having the A2W post-FMIC. But from a thermal-management perspective maybe the A2W should be pre- FMIC? I.e., hottest compressed air off the turbos should contact the A2W first?

I think the issue you'll run into are the various front facing/centerfeed manifold arrangements, and also twin and single turbo plumbing will cause a configuration nightmare. I'd like to hear someone's vision for an intake manifold which can fit everything.

Issue is zero room. Unless you use an aquarium cooler lol. Not sure if that's a thing but sounded hilarious in my head.

If you're going to go to the trouble of getting all the N20 bits and pieces, F just spraying the IC with it!

I thought that too, but there really is no room over there and much more room on the driver side. Also, this would not be compatible with top and bottom mounts equally. lastly, I think the temperature delta between the two would cause condensation. Would probably be better to step the temp down? Besides, if the A2W does a good job, the FMIC might actually heat the air, wouldn't be as effective at that point.

The work's already been done.
Here ya go. Ready for Chiller Killer fitment instead of water (although I'd just use water and a small electric pump). And yes, I realize this is for an S54 but the principle is the same. If someone can make cast and sheet metal manifolds, they can make this.

I see what you mean. But what is the difference between putting the cooler inside the manifold vs what I'm suggesting, a barrel style core where the charge pipe goes? The above method may be more efficient but who is going to make it? Wouldn't my suggestion still suffice?

That area is cramped already. Then you have everyone with inlet relocation kits that have coolant tanks in that area. This is a solution that would def work for you but if you get a company like Evolution of Speed on a project like this, they can fab up a complete intercooler / manifold combo for the price of an intercooler and manifold. Oh, and then add the port injection to the manifold like EoS already does and you're a full blown winner. The very large heat exchanger for the water to air cooler and the new pipe that goes from the outlets to the charge pipe goes in the place of the intercooler. It would be a tidy package.

Well I've already got that manifold, can't imagine buying another. I have also spoken to them about this same topic already. I think they have a different vision than what either of us are talking about(or I'm misunderstanding). A barrel core could fit there, with mods by most fab shops. It doesn't need to be a candidate for mass production like a casting would. So while I agree a dedicated manifold would be better, I am curious what people think about the next best options with some compromises.

Where would you suggest that be mounted exactly? I've seen that style core before but it doesn't really fit the dimensions of the available space, without removing things.

Remove the charge pipe and relocate the power steering reservoir. Put a BOV on the cooler or on a silicone tube with a Tial flange.

Barrel a2w intercoolers don't support big power. They are small and restrictive.

That VF is just like a RMS SC kit we installed on e46. They are very heavy and are meant for sc.

You guys are over thinking it... You just need a normal a2w intercooler, a large heat exchanger, good size pump, and large lines.

It wouldn't be difficult to fit a n54 with a s55 style IC and large heat exchanger where the a2a intercooler use to be.
