I don't remember what they started with but given the big gains of I think 150whp+ AMP saw with that modified procharger intercooler at around your power level, I'm surprised no real big gains noticed.
I would have thought some fairly noticeable benefits vs. the small stock ecs intercooler.

Not sure if you meant it the way that it came out but that is false.
You wont see any cooler intake air temps because the IAT Sensor is before the fuel. But you do get the added benefit of higher octane and burn properties. And your combustion temperatures will drop. if you had a sensor placed as close to the combustion chamber as possible that could hold up to fuel saturation and be after the fuel is injected you would see a major difference in IAT's.

I was sure that's what he meant just wanted to clarify it so someone doesn't misunderstand what he was said.
But it absolutely does cool your intake air temperature. not in the charge tube or in the top of the intake. but in the bottom of the runners and into the combustion chamber it does. But due to the location of the sensor it isn't seen. That's why you have cars out there (granted mostly race cars) running crazy timing with no intercooler on E-85.

I'm not trying to go back and forth or argue. I see your post and relies you are knowledgeable and a senior member.
E85 is only around 105 octane but resist knock better than higher octane fuels. and that is mostly due to the fact that it has a higher latent heat of evaporation which means absorbs more heat (cools IAT'S) from the combustion charge as it goes from a liquid to vapor, which in turn makes it more resistant to detonation.

Honestly the crash bar thing is way overrated IMO. The foam piece that goes over it still blocks everything, and even if you remove that the ammount of air is limited by the opening on the grill, which is smaller than the inlet to the radiator/fmic. I think the key to keeping cool is fresh air to the radiator/condensor. I could have easily go 8-10" wider, but I wanted the fresh air to filter condenser and radiator.

Foam isn't removed. No difference to bumper cover on fitment or how it mounts, because nothing changed.
IATs never went over ambient in 2-4th gear pull, but it is powering through clutch, so can't report any performance gain besides it makes enough power to just free spin the clutch at will. With it just spinning clutch though I don't know if this is accurate, but on street with power turned down 2-4th they never go over ambient now. Before it would be below until top of 4th then go up quickly.
Also MAP sensor pegs 250kpa at 6k now. Before it only hit 245kpa peak. So making more boost now for sure.

good stuff. time for a triple plate!
I always wonder how much saturating the IAT sensor with meth may give a falsely low reading
modifying the crash bar certainly helped my car too. easy to use a hack saw blade to trim the foam without changing how the nose fits on the car or is supported. If having issues cooling I'd recommend it personally at least.

So basically it appears the larger FMIC avoids heat soak for longer time, and may make more power, but until a clutch that can hold is put in, no conclusion can be made. It does keep IATs lower for multiple runs, but for a single 4th gear pull it doesn't make a difference at all. So would it effect a single dyno pull, I doubt it. Would it effect trap speed at 1/2 mile, probably.
Of course spraying the IAT sensor with meth ***** everything up, but my car runs on meth, and is setup that way, so if someone wants to find out without meth, they can do it on their car. I'm not removing meth or messing with that just to test internet theories. I'm sure it has a huge effect.
