It actually tucks really close to the side and barely overlaps the radiator. I doubt it would rob much air from it.

Yeah the afe style one doesn't stick out too much, so it doesn't block air flow from the kidney grills as much. The eventuri one takes up like a quarter to half the kidney grills.

No, I don't think so. Seems like a nice little added pathway to funnel a little cooler air from the nose of the car into the intake without removing any air from the DCT cooler or radiator. I'm sure the air in that area just buffets up anyways.

Probably wishful thinking, but IATs always increase under hard braking from reduced airflow across the FMIC so maybe this will also keep a little more concentrated flow moving into the intake. I just need to go look at my Evo3 pics to make sure I have clearance.

You can pick them up for $50 right now, so worth a shot! Thanks for the heads up.

Yeah man you got it, hopefully it helps out with IAT's.

I know the MILVS are proven when I built my engine I was going to use them, I had a few concerns tho and wanted to see how they progress. I was also going to do the exhaust cam swap but my builder talked me out of it.

The MILVS look really good on the s55 so far, it gave the s55 a bunch of area under the curve at the top end of the rpm band where the stock turbo nornally dips off dramatically. The MILVS were also installed by a really reputable bmw shop (bpc). But yes it does lack some testing data, but knowing cobra Marty it should be a solid product. Someone here was going to try it on the m2 as well, he already bought the MILVS just waiting for an install.


In terms of the exhaust cam it's not available yet, if you're talking about the n52 exhaust cam then yes your builder was right to talk you out of it. The results behind those cams were sketchy and imo probably don't offer any gains. But the modified cams that Marty is working on should be legit.

I have seen and read plenty on the MILVS and it's not the product I had concerns about. The n52 cam was what I was looking at.

Yeah imo the n52 cam doesn't give any gains, and it was the guy testing that provided the shady data. He likely switched tunes afterwards.

That's me, but things have taken a back seat since I bought a home. The MILVS, Blistien coilovers, Turbosmart Diverter Valve, and VRSF Competition intercooler all need to be installed. But before that, I need a HPFP upgrade...

Also, interested in the findings on the scoop, I have the eventuri one - I doubt it does much, but fluid mechanics isn't my thing

Anyone out there have data on how much a GTS or CS style vented hood helps to lower engine temps?

I'd be curious to see the data as well. In theory it would be effective because it allows the positive pressure building up under the hood to vent and thus creates a vacuum behind the radiator allowing for better air flow.

I also recommend getting a crank seal plate as well, just incase water makes its way down to the serpentine belt and causes it to slip. It is an unlikely occurance but it could happen.

Yeah, all the race cars and high end sports cars have vents, but placement and size is key.

It’s a nice cosmetic upgrade as well, and I wondered if either style was also a simple engine temp bang for the buck upgrade compared to other cooling alternatives being thrown out.

I don’t know anything about the crank seal guards, but this one seems cheaper than Kies? https://www.fcpeuro.com/products/bmw...8aAi92EALw_wcB

Yeah that's the VTT one, a decent choice as well. If you get the VTT one you might as well buy directly from VTT and get a deal on the CBC as well.

Personally I prefer the Malo industries one: https://maloindustries.com/ or on ebay (still sold by them) for less https://www.ebay.ca/itm/N54-N55-Cran...-/174465721785

I think it is less on ebay because their site should be in CAD as well.


Ok the reason why I prefer the malo plate is because:
1) The tabs are a bit more reinforced than VTT meaning it is stronger
2) The tabs are round so it is easier to position, whereas the VTT plate is more oval.
3) comes in silver, I personally don't like anodized finishes because I've had so many poor anodized parts in the past and they flake.
4) Comes with good hardware - i.e. stainless bolts (won't rust whereas the grade 12.9 alloy steel VTT bolts can rust. It only needs to take 30 nm of torque iirc so such a strong bolt is not needed), and loctite
5) CNC aluminum like all other plates.

Overall I personally prefer the MALO plate, as it is also made in Canada and I like the guy who makes it, but the VTT plate is a good choice as well and it would be a close second for me.

I do not personally like the Kies plate because of the mounting ring, not all bmws - especially the n54 has the recessed crank seal. Most of the time the N55 and s55 does have a recessed seal but if your car doesn't or the seal is not recessed enough then that can cause an issue. So I rather not pay double for a mounting ring that may be more of a concern that a benefit.

Behind the radiator is a perfect position for placement, and that is exactly where the gts vent is.

Just a little sneak peak

Before the major indepth article about why crank seal plates are needed, what causes failures, and why I like the malo one the best - this will be a long read but imo worth it.

No, I don't think so. Seems like a nice little added pathway to funnel a little cooler air from the nose of the car into the intake without removing any air from the DCT cooler or radiator. I'm sure the air in that area just buffets up anyways.

Probably wishful thinking, but IATs always increase under hard braking from reduced airflow across the FMIC so maybe this will also keep a little more concentrated flow moving into the intake. I just need to go look at my Evo3 pics to make sure I have clearance.

You can pick them up for $50 right now, so worth a shot! Thanks for the heads up.
Gents

I used the AFE scoop on my F20 m135i which has sealed air intake lower box. Effects on m2 may not be as noticeable as M2 lower part has an extra hole in it to allow more air to flow.

Scoop may not be as effective on m2 n55 as it would be on f2x n55

Hey Gents, no data on the AFE scoop but for what it costs & the simple install its certainly worth a try imo.
As for the GTS vented bonnet i am certain it helps with cooling, the amount of heat you feel coming from the vent is proof its more than cosmetic.

I grabbed a scoop b/c I figure WTH, I'll give it a shot.

I'm getting more interested in the idea of the vented hood b/c they also look great. Thoughts on if the CS or GTS style would flow air better and let less water in?
