so that black plastic pc with an "M2" is the shroud that redirects the flow into the top portion of the FMIC? That's stock? if so then I guess that was really meant to redirect the flow to the radiator coz the stock FMIC is just way down low (short).

I assume it does that, yes. The FMIC is much closer to it than with the stock setup though so it might disturb the airflow a bit. Either way, I am fairly confident that things are better with it than without it.

Yes, it is stock.

That shroud most likely sits directly on top of the stock IC. Without anything to sit on top of, I wonder if it flaps and vibrates at highway speed.

are you happy w/ the performance of the ER?

I do not think so, it's pretty well attached.

I am still in the middle of installing it, everything is off but I found that a bracket was broken [1] so I am waiting on the part before putting everything back together with the ER FMIC.

So I cannot tell you how it performs but the fit and finish of the entire kit is top notch.

Correct, it's for the radiator, not the intercooler.

I don't know about that - it was spaced out for the radiator, but the ER intercooler sits closer and occupies most of that space. On my car - there isn't really any way ducting could work without blocking the top half of the intercooler.

I messaged Fred from ER to ask about this and will follow up once I get a reply.

Here is what Fred said:

Quote:
Typically #2 in the diagram is removed. You can reinstall it but I believe you need to trim it to fit.

It helps so trimming it to fit would be ideal. However, the difference is very small and possibly insignificant so removing it isn’t a big issue either.
So I guess either way works but I'll probably try to fit it.

Yeah I personally would likely also try to keep that pc that scoops some air into the back of the bumper. Seems to make sense, even though could be "insignificant".

How much better performance does the VRSF race provide over their 6.5 comp?

Considering following M2guru in swapping from CSF to VRSF and in deciding if the extra bs involved in the Race is worth the hassle.

The Comp has the race fin pack and depth, but is about the size of the 5" version (a little thicker as said as above)

The Race is better - the frontal surface area does all the heavy lifting when it comes to cooling.

On the VRSF website, the "race" isn't listed as for the M2. I assume it's a bit of a custom fit? Piping, too, or just the brace? Maybe I missed that somewhere in all the posts. I may consider that one instead...hmmm...

Yeah, see your thread in the track section - it will require the M235i V brace (about $50)

And the current question is if the additional blockage of the radiator by the bigger ICs significantly impacts the cooling ability of the radiator for track use... Maybe I should start a gofundme so I could buy them both and then run them back to back and share the results... :-)

I think what I will do is just run the 6.5" for a while to get data and if I feel like it's not cooling the IAT enough then make the move to the race. My purchase of coilovers keeps getting pushed back every year... :-(

The VRSF is like an inch taller than the CSF - the same height as the ER. I don’t believe there is any impact to the cooling system, but I’ll watch your progress closely.

I wouldn’t be too surprised if the cooling increase is just marginal over the CSF though, as the comp isn’t as tall - it may be a tight squeeze and require you to use washers to space out the brace (just eyeballing it)

I’d support a go fund me - love data
