Finally Installed my RA Bumper Vent for larger intercooler

I really think that people have taken this crash beam thing way too far. I bet people would be alot more comfortable if we called this a bumper support, because that's what it is..lol. It is quite literally there to adhere to the 5mph crash specs as laid out by the US government for all vehicles and hold the bumper skin on. But keep in mind that some vehicles accomplish this with a fiberglass crash beam, i.e., 2g DSM cars. How do I know this? By putting a larger FMIC on one, of course . I really don't want anyone to take this as me telling them that you are silly for not doing this mod, but to be uneasy about it from a safety standpoint is not realistic. I will say that if want or have a taller intercooler (i.e., evo x) and you don't have this done (or some other method of getting more air through the top of it, if there are others out there), then you would have been better off just putting a block of aluminum along the top of your stock RA intercooler, because the part not seeing airflow is not working as an air to air heat exchanger as intended, but simply an increased mass heatsink.
Again, I am not poo pooing anyone being apprehensive in doing this, and I am by no means twisting anyone's arms. I am just trying to make sure everyone has all of the facts to make an educated decision. And another point is that if you are that worried about cutting a few holes in the stamped sheet metal crash beam on your car from a "safety" standpoint, a few pieces of sheet steel and 20 minutes with a welder can make the piece with the holes cut in it significantly stronger than the oem piece, "upgrading" your "safety"...lol.

Honestly I personally am not worried about cutting the holes, Its more of a price standpoint ahaha and also deciding whether to drill/dremel myself or to buy the evo x beam!!
I do think it is a great piece to our Ralliarts, performance wise as well as aesthetically speaking

Just remember I have NO CLUE if the Evo beam will work. I actually don't think it will as it appears to be missing a few mounting points for the RA bumper. People tend to think the two are interchangeable, but the front ends are a great deal different. I have yet to see someone try an evo crash beam with one of these, but if I do, I will let everyone know.

A strong dremel will most likely not get the job done, unless you have a very good cut-off wheel. You would be better off with a good sawzall or angle grinder with a nice cutting disc.

Here is a comparison of the OEM FMIC vs a CBRD FMIC and the bumper was NOT modified in any way.. Looks like it's working to me: https://www.evolutionm.net/forums/8375796-post169.html

I'm curious if the USDM does as well since it's much cheaper.

Please do not spread false rumors and misinformation as fact on this site. We are here to learn and to help one another, so making up information based on your best guess only leads to ignorance.

I did not make a statement based on my best guess or some other information. It is called thermal dynamics and heat transfer 101. The thermal conductivity of aluminum is of a fixed quantity. An intercooler is set up to get rid of the unwanted thermal energy through forced convection (air being forced across the intercooler). In an absence of forced convection, i.e., no airflow, the intercooler can only work through radiation. So, to reiterate, my statement of fact that if a portion of the intercooler does not have air going over it, that portion is only working as a radiant heatsink is 100% true, valid and verifiable. At that point, that portion of the intercooler is not working as intended. Will a larger intercooler keep the IAT lower versus the stock without this? Absolutely. Will the larger intercooler with airflow going across the entire surface area keep the IAT lower versus the larger intercooler with the upper portion blocked? Absolutely. The long and short of it is if someone thinks an intercooler doesn't perform better with airflow going over the entire surface area as it was designed to do, they need to buy a honda.
And as far as the very nice comparison Bryan did between the stock intercooler and the CBRD intercooler, that is extremely useful information, but I am pretty sure you are drawing the wrong conclusion from the data. The CBRD intercooler is a bar and plate intercooler versus the tube and fin we have stock, so if it were equal size, it would still work more efficiently than the stocker. But that isn't the only reason that intercooler outperforms the stock one in his data. That intercooler is very nice and SIGNIFICANTLY larger than the stock fmic. To ignore that fact shows that you don't understand why he saw a drop in MAT/IAT delta T like he did.
These are the facts. Without considering the facts before making statements based on your best guess or misinterpreting information you have seen, you are doing exactly what you thought I was doing, but I hope now that you understand that I was not spreading ignorance. I am trying to eliminate it.
