I've attached some pictures for your viewing pleasure.

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.

[vrooooom]

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.

Yes, it is stock.

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.

[c0riolis]

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

[c0riolis]

Here is what Fred said:

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.

[vrooooom]

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

Would be good to see a heads up bn the VRSF, BMS, and MAD Race intercoolers to compare quality, fitment, and performance bn them to determine the pros and cons of the top bar & plate ICs.

Need that water to air setup to materialize as an off the shelf option. 30-35f over ambient on a 93* day doesn’t blow my hair back and makes me question if it’s worth chasing with the Evo3 or if I just enjoy the car on the street and in the fall/winter on track for a few years before going the M2C route.

It’s been a tremendous platform to grow with, it just isn’t the optimal tool to chase the big fish with under a heat warning.

StageFP made one, I think it's $1000-1500

Don’t see it for sale anywhere online? Is anyone successfully tracking their car with it?

Most people won’t see those deltas with the top bar/plate ICs or the Evo3 when just driving on the street. For instance, on the street I’m only 10-13F above ambient up to 117mph, 15F at 130mph, and that’s with 470whp.

For guys like us that have higher hp M2s and track them pretty hard, that’s when any of these ICs are going to see 30-35F above ambient on 140-155mph tracks, lap after lap on hot days. Thing is, that’s perfectly fine for cars running E30-60.

On 93 octane timing starts to get pulled above 110F. On higher Emix, I’ve only seen it being pulled with IATs >145F—that was back when I had my Evo2 on track and was seeing 50-60F above ambient IAT and why I switched to the Evo3.

So, unless it’s a 115F ambient day (at which point I will not be on track!) we shouldn’t see timing pull from any of the top bar/plate IC’s or Evo3 when running an Emix. That sounds like a cheaper approach to me than water to air retrofit or a bad sounding, heavier M2C.

Still would like to see how the top bar/plate ICs stack up.

Side note: Any S55 guys I know tuned to our power level and are actually pushing the car hard still have to upgrade the exchanger and TMIC for additional cooling and they’re still slower bc they’re heavier. They can bump their tune up a little more to even out or get a little better on power to weight, but they still have more weight to brake and sling around the corner. And, if all else fails, I just out drive them.

I thought I’d fair better with IATs below 135* on E50 but it wasn’t happy. Maybe something was off. Got the log to Bend Cal to review.

If I could get full strength even for 15 minutes I’d be a happy camper. Wouldn’t let me rip 2 laps without falling on its face today.

On the street it’s fine, and it’s a street car 340+ days a year so there is that.

Interesting. Let’s see what Bend says. I’ve never noticed timing pull at 135F with high Emix.

How were your other temps?

Rock solid but I’m 6MT, Barber is a 3rd-4th gear track, and I didn’t get to lay 450+ down for extended periods. Had I been able to run it harder, I think oil temp would have easily hit 240+ as all my cooling is stock beyond intercooler.

Coolant seems to fair the best out of the three. IATs are my problem right now.
